Using MySql and PHP with Dreamweaver on a Mac

Hello all,
As always if the answers to these questions are obscenely
obvious please humour me.
I use XHTML and CSS in my websites and realise that it is
time that I dabbled with SSI. So I've started using PHP.
However, I have been following the installation directions of
MySql and am running into problems. I am installing the relavent
software and am then unable to find it on my Mac, the startup files
are there but the actual MySql data appears to not be installed
despite my computer telling me it is...... I am using a G3 running
OSX 10.4 is this good enough? I noticed talk of needing a PowerPC
or Intel mac. Is this the case?
Also, would I need MySql installed on my actual computer if
the my servers have it already? And does Dreamweaver 8 have both of
these programs installed as standard?
If you could help out I would be very appreciative as I would
like to learn this stuff and I appear to be struggling at the
outset....
Cheers
M.A

MySQL is a relational database management system that
comprises a
database server and several utility programs. Although you
install it
like any other program on a Mac, the similarity stops there.
First, the point about PowerPC and Intel Macs is that there
are
different versions of the MySQL installer for each type of
processor.
I'm pretty sure that a G3 is OK, but you must choose the
PowerPC version
of MySQL, not the 64-bit or x86 (Intel Mac) version.
Once you have installed MySQL, you need to drag the
MySQL.PrefPane icon
from the disk image onto your System Preferences. This
installs a
Preference Pane that enables you to start and stop MySQL. The
Preference
Pane has an option to start up MySQL automatically, but in my
experience, it doesn't work on Tiger. You need to open the
Preference
Pane, and click Start MySQL Server each time you start your
computer.
The best way to work with MySQL is to use a graphical
interface, such as
phpMyAdmin. As Osgood has mentioned, I have written a book
about PHP and
Dreamweaver, which goes into all the necessary details. It's
also very
Mac-friendly with separate instructions where necessary for
PC and Mac.

Pb using mysql with php

I currently have apache/php/mysql installed.
[root@gaboo /]# pacman -Qi | grep apa
apache 2.0.53-2
[root@gaboo /]# pacman -Qi | grep mysql
mysql 4.1.10-1
[root@gaboo /]# pacman -Qi | grep php
php 5.0.3-5
But when I tried to make a mysql connection, I get
Fatal error: Call to undefined function mysql_connect() in /home/httpd/gg/pageprincipale.php on line 16
Moreover, when I display this php page :
<?php phpinfo(); exit(); ?>
I don't have a mysql section, displaying its settings.
The mysql extension is built-in into php5, everything seems at the right place, I can't find why it doesn't work.
Any ideas ? :?:

It works, but how often do I need to this? Everytime Pacman upgrades?
Instead, you can change the line:

How to create a dynamic newsflash using dreamweaver and PHP

Hi there,
I would like to create a dynamic newsflash using dreamweaver and PHP in that the newsflash will be pulling information from a MySQL database. The newsflash should also have a link to view more information about the piece of news a user wants to know more about. Which tools do I need to use in dreamweaver and how's the procedure to go about that. Any advice is highly appreciated. Thanx in advance!

I think you´ll need at least a MySQL table with the following columns:
- id (primary key, int, auto_increment etc)
- news_headline (varchar)
- news_teaser (text)
- news_content (text)
What I´d personally add are columns such as:
- news_date (date or datetime)
- news_external_link (varchar), if a "read more..." link is supposed to navigate to an external URL rather than displaying the contens of the "news_contents" column.
Based on such a MySQL table it should be easy to use Dreamweavers standard Server Behaviors to create the usual datalist.php, insert.php, update.php and delete.php documents, and there are numerous tutorials out there which will teach you how to do that.
Am I right when assuming that you´ll also need to know how to automatically pull, say, the 5 most recent news records from the database ?

SQL Verification Problem / Muse Form Issue (Server uses MySQL muse uses SQLite) I'm in desperate need of help

       Alright well here is my issue... I have been trying to fix it on my own for the past week non stop and I have finally came to a solid conclusion as to the cause of the issue.
   I always get the error "The server has encountered an error..." in red text when anyone tries to submit a form and also when I try and test it myself. This led me to test the server / site for compatibility or issues by using the test:
mydomain.com /scripts/form_check.php
I got the first two checks green (pass) and the third test threw a red check meaning I was having an issue with SQL verification. This then led me to days of trying to work with my hosting provider (one.com) trying to solve the problem and I was told that they use mySQL on their servers and that they couldn't do anything on their end to solve the issue. I read alot that we are recommended in this case to try and get our host to add the SQLite database to their server or whatever it is they would do, long story short I guess many people are able to ask their host to make SQLite work and most accept and add SQLite functionality to their servers but unfortunately my hosting provider doesn't want to do this and they said they were sorry and that I would need to either switch the script to work with mySQL or figure something else out...
   I took a lot of time building my site and I dont want to take the form out. I absolutely need it... I know many post on here saying "forms dont work, oh poop " or "adobe sucks I dont want to use business catalyst grrr" but I tried to find the source of the problem and I've successfully came to the conclusion that my issue is that my script wants to use SQLite but in order for my sites forms to work the server needs to have SQLite as well... My idea is that if I can configure the script and the site itself to use mySQL instead of SQLite the SQL verification will then not be an issue and my websites forms will function with no issues. I am curious if a member of the staff with adobe has experience with this particular issue and can help me out? or if a member of the adobe community has solved this problem? If not I am hoping that with the description I provided that someone with knowledge of mysql, sqlite or code in general could help me modify the script or write a new script that will allow the forms to work properly. I know its a long shot, I say that because this discussion is full of people who used muse in favor of dreamweaver because just like a large number of people in the muse discussion area, I'm a graphic designer, with plenty of computer experience, art and design skill and I am extremely familiar with photoshop. Muse is perfect in so many ways. In fact, like I mentioned above, I don't even have a complaint at this time about muse. I understand the form issue in this case, and I imagine in thousands of other users situations, is all just a matter of scripts and compatibility.. Its just a little issue between the SQLite scripts we are all given when we export our muse website and the SQL version our various hosting service may be using on their servers.
   Just incase I missed anything, to provide just a bit more info on the topic and myself for anyone who may be able to help:
I can alter the text inside of the scripts easily if anyone happens to know any lines of code that easily solve this issue (making the muse contact forms, which are native to SQLite, functional on a server using mySQL)
I was told one way I could make the forms work on a server using mySQL (or any version other than SQLite) If I were to make changes to adobe muses SQL version by converting the SQLite db to mySQL db (db = database)
I am computer literate and I can take any directions necessary, I really just need to get this done, I really appreciate any help I can get!!
Thank you in advance,
Roy

Restrict Access to Page Using a password.php Instead of Server Behavior

I previously used "log in" and "restrict access to page" server behaviors for my client portal when I only had one client. I had my username and password stored in mySQL database. I recently have gained more clients that all needed to be redirected to their own customized landing page when logged in. Because of this, I used a password.php to store the usernames and passwords and to redirect to different pages. Now, I am wondering how I can restrict access to these pages (i.e. someone won't be able to access the pages by typing the url) since I will not be connecting to a database anymore.

I'm also confused by your statements.
>Now, I am wondering how I can restrict access to these pages
>(i.e. someone won't be able to access the pages by typing the url)
>since I will not be connecting to a database anymore.
It doesn't matter where you store the credentials - database or php file - the techniques for restricting access will be similar. I really don't understand why you moved away from the database when you got more clients. The more data you need to manage, the more reason to store it in a database.
After logging in, most sites direct users to the same page, yet pull user specific data from the database. If for some reason you can't do this and need to built individual pages for each client, then store the 'landing' page for the client in the php file or database. Restrict access to each page by comparing the logged in name with an allowed login name. Or a more dynamic approach would be to dynamically pass the page name to a database query that validates that it's ok for the logged in user to access.
Also, these questions are more appropriate for the app dev forum.

Apache, MySQL, and PHP

I am new PHP development and working on a test project. I've installed Apache, MySQL and PHP on my Windows XP box and now I'm a little confused. I created a database and some sample code to retrieve data. Now, on a server I'm using which supports this how do I upload this to the server for use?
I hope this makes sense. Is there a built-in app for that or do I upload my created db to the server.
UPDATE: I forgot to add that I am working locally and now would like to port this over to my domain and server. My host uses a linux box with apache.
Thanks in advance,

Hi,
Download the mysql admin gui from here : http://dev.mysql.com/downloads/gui-tools/5.0.html
If your host server allows connections from other hosts you can use the mysql gui to connect to the local database as well as the host database and export the tables to your new database on the host. This is the way I prefer to do it... but some hosts only allow SQL connections from the localhost itself which basically means you won't be able to connect to it using the mysql gui tools.
However you can still generate the database scripts from the gui tools and login to your hosts mysql manager - possibly phpMyAdmin and then simply execute the SQL script.
Hope this helps,
Brendan

Highscore list using Flash and PHP

Hi,
I want to make a highscorelist using AS3 and PHP(MySQL).
I cant find a good tutorial on internet how to make something like that but I got this so far:
import fl.controls.TextInput;
import fl.controls.TextArea;
var variables:URLVariables = new URLVariables();
variables.name = "Wil";
variables.final = 2000;
var request:URLRequest = new URLRequest();
////insert in the location of the php script ////////////////
request.url = "http://www.justenter.nl/script.php";
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.load(request); //sends the request
//when the request is done loading, it goes to the completeWriting function
loader.addEventListener(Event.COMPLETE, completeWriting);
function completeWriting(event:Event):void {
    var writingCompleted:TextField = new TextField;
    writingCompleted.autoSize = "center";
    writingCompleted.x =200;
    writingCompleted.y= 200;
    writingCompleted.text = event.target.data;
    addChild(writingCompleted);
He is sending the score and name to the database but he is doing that when i press ctrl-enter. He is sending the data I have given in:
variables.name = "Wil";
variables.final = 2000;
I want a input textfield and a button. And When I fill in my name in the input textfield he send it to the database when I press the button.
Is there someone that can help me out?
Tnx

import fl.controls.TextInput;
import fl.controls.TextArea;
var variables:URLVariables = new URLVariables();
//variables.name = "Wil";

request.url = "http://www.justenter.nl/script.php";
request.data = variables;
var loader:URLLoader = new URLLoader();
submitBtn.addEventListener(MouseEvent.CLICK,submitF); // where submitBtn is your button
function submitF(e:Event){
variables.name=nameTF.text; // where nameTF is your input texfield
variables.final = score; // where score is the variable you use to tally user score

I want to create a mysql and php forum.. need advice

Hi,
I want to create a forum to put on my site.. it doesnt have
to be very complicated - it can be as simple as this one
http://boards.gapyear.com
http://boards.gapyear.com but
I want it to be fully integrated into my site (so would prefer not
to use phpbb etc).
I'm using phpmyadmin and Im not too hot on mysql or php (but
am willing to learn!) so was wondering if anyone knows of a really
good tutorial to talk me through the processes of setting up such a
forum?
Would appreciate any advice.

The people who make the free forums (phpBB or SMF for
example) do it for
free in there own time and are experts in there field. They
need to be,
forums are complicated and prone to being hacked, so security
is your
number one concern.
Most can be integrated into your site with a bit of work, but
thats much
less work than creating your forum.

How to use MySQL to create a database

I downloaded MySQL and opened the folder and saw a plethora of files. I'm lost and don't know where to start. I want to create a database. Any suggestions? I have dreamweaver cs5. My computer is a mac book pro OS10.6.8.

To amplify osgood_'s excllent suggestions - MySQL is a database application that runs, typically, in a server environment. Full stop.
This is not a simple "install the app and everything's good" type of program. Please do more research before attempting to install it. Also understand the security implications of running a database on a server (or even locally) and learn how to lock it down. Finally, to install and run MySQL locally, you better get really good with Terminal.app and learn how to launch MySQL and configure it from the command line.
I personally use MAMP (Mac Apache MySQL and PHP - see http://www.mamp.info/) to do MySQL/PHP development and testing as it doesn't mess with the internals of my machine, keeps everything in a MAMP folder in my Applications folder, and it has a control panel for easy start/stop of Apache/MySQL services.
Not trying to squash your dreams of running MySQL locally but you do need more "domain" knowledge before doing so.
Hope this helps.

Will there be future database support of mySQL and php 5.5 on the dreamweaver CC?

Will there be future support of mySQL and php 5.5 on the dreamweaver CC? I have seen various topics on this, and havent seen any answers on this as of yet. I feel it is very important to have this available, and not from some external company as an addon or something. I come from cs6 products, and am debating whether or not I should even join the creative cloud, or participate any further with Adobe products.
I have been a fan of Adobe for quite some time. However, if there isn't going to be any database tools within DW, I may decide to pass on the CC and comepletely hand code it all from now on.
Has anyone found yes or no answer to this yet? I am assuming there is no news yet, as the adobe posts I have read have no additional info other than they haven't updated the tools, thus removing them from CC.

I very much doubt that any future addition of DW will include any 'official' support for mySql database interactivity. CC hide the server behaviours this time around in an extention to be activated by the individual, its still available in CC but at the users own disgression, mySql is dead. You should be connecting and querying your databases using other methods like mySqli. Adobe have seen it fit to go in other directions and dispite the outcry of dropping the server behaviours there has been a deafening silence from Adobe. From that you can take it they think it is no longer an important part of their software package.

I have not updated to CC because it contains zero that would be of importance to my workflow. The more experienced a code writer you are the less DW has to offer. Any serious code writer would not miss DW if it went out of business. Fireworks is more important to me which LOL is going out of business...go figure. I think the Adone execs are screwed up snorting cocaine or something. I'm not really even sure why I use DW, maybe out of habit.
Certainly hand coding for database connectivity and querying is the ONLY way to go if you are not interested in third party extentions because continuing to use the current available server behaviours is a backwards step. I don't know how good these third party extentions are because there has never been a lot of talk about them around here which leads me to believe not many are considering them, maybe.

Any tutorials on creating a simple Login using Mysql and sessions?

Hey guys. I cannot seem to find any information(online) or books that cover sessions in JSF and how to do a simple log in. I can get the application to query a mysql table and check the credentials and go to the next page, but I'm not sure how to make that page locked from non authorized access. I am very familiar with PHP and using it to create database driven applications. It's very straightforward, making safe logins using mysql, and creating sessions once the user has logged in(making pages locked unless the user is logged in, etc).. I have the core java server faces book but it's a joke. I feel like its an incomplete book. It merely skims a topic, and when you think it's going to get interesting it moves on to something else. It teaches basic stuff but nothing of what I want to do(or need to do). The older Javaserver faces book that came out in 2004 from O'Reilly doesn't seem to help either. I'm just wondering where people learn JSF at. I know Java, I would say pretty well as far as desktop applications go. I really like the way JSF is layed out and would really like to use it in my next project. At the level I know it now it's perfect for static web pages with no dynamic information.(but I could use plain html for that). Thanks for all your help.

Map the filter on the desired url-pattern and write doFilter() logic which checks if the user is logged in (basically: if there is an User object in the HttpSession) and handle accordingly (chain.doFilter() on success or response.sendRedirect on fail).
and creating sessions once the user has logged in(making pages locked unless the user is logged in, etc).. The HttpSession is backed by a cookie (as is PHP's $_SESSION, did you know that?), you don't need to do any low-level stuff with cookies. Maybe at highest if you ever want a "remember me on this computer" option.
booksThe mentioned books learns you the JSF basics. They doesn't really learn the best practices / practical use cases. There you have other resources for (or just practical experiences). Besides, I recommend you to go get a book which covers JSF 1.2 or newer. The mentioned ones are outdated, as is everything else older dan two years in the programming world.

CASE value WHEN [compare_value] THEN result [WHEN [compare_value] THEN result ...] [ELSE result] END
CASE WHEN [condition] THEN result [WHEN [condition] THEN result ...] [ELSE result] END
The first version returns the result where value=compare_value. The second version returns the result for the first condition that is true. If there was no matching result value, the result after ELSE is returned, or NULL if there is no ELSE part.
mysql> SELECT CASE 1 WHEN 1 THEN 'one'
-> WHEN 2 THEN 'two' ELSE 'more' END;
-> 'one'
mysql> SELECT CASE WHEN 1>0 THEN 'true' ELSE 'false' END;
-> 'true'
mysql> SELECT CASE BINARY 'B'
-> WHEN 'a' THEN 1 WHEN 'b' THEN 2 END;
-> NULL
The default return type of a CASE expression is the compatible aggregated type of all return values, but also depends on the context in which it is used. If used in a string context, the result is returned as a string. If used in a numeric context, then the result is returned as a decimal, real, or integer value.
Note: The syntax of the CASE expression shown here differs slightly from that of the SQL CASE statement described in Section 17.2.10.2, �gCASE Statement�h, for use inside stored routines. The CASE statement cannot have an ELSE NULL clause, and it is terminated with END CASE instead of END.
IF(expr1,expr2,expr3)
If expr1 is TRUE (expr1 <> 0 and expr1 <> NULL) then IF() returns expr2; otherwise it returns expr3. IF() returns a numeric or string value, depending on the context in which it is used.
mysql> SELECT IF(1>2,2,3);
-> 3
mysql> SELECT IF(1<2,'yes','no');
-> 'yes'
mysql> SELECT IF(STRCMP('test','test1'),'no','yes');
-> 'no'
If only one of expr2 or expr3 is explicitly NULL, the result type of the IF() function is the type of the non-NULL expression.
expr1 is evaluated as an integer value, which means that if you are testing floating-point or string values, you should do so using a comparison operation.
mysql> SELECT IF(0.1,1,0);
-> 0
mysql> SELECT IF(0.1<>0,1,0);
-> 1
In the first case shown, IF(0.1) returns 0 because 0.1 is converted to an integer value, resulting in a test of IF(0). This may not be what you expect. In the second case, the comparison tests the original floating-point value to see whether it is non-zero. The result of the comparison is used as an integer.
The default return type of IF() (which may matter when it is stored into a temporary table) is calculated as follows:
Expression Return Value
expr2 or expr3 returns a string string
expr2 or expr3 returns a floating-point value floating-point
expr2 or expr3 returns an integer integer
If expr2 and expr3 are both strings, the result is case sensitive if either string is case sensitive.
Note: There is also an IF statement, which differs from the IF() function described here. See Section 17.2.10.1, �gIF Statement�h.
IFNULL(expr1,expr2)
If expr1 is not NULL, IFNULL() returns expr1; otherwise it returns expr2. IFNULL() returns a numeric or string value, depending on the context in which it is used.
mysql> SELECT IFNULL(1,0);
-> 1
mysql> SELECT IFNULL(NULL,10);
-> 10
mysql> SELECT IFNULL(1/0,10);
-> 10
mysql> SELECT IFNULL(1/0,'yes');
-> 'yes'
The default result value of IFNULL(expr1,expr2) is the more �ggeneral�h of the two expressions, in the order STRING, REAL, or INTEGER. Consider the case of a table based on expressions or where MySQL must internally store a value returned by IFNULL() in a temporary table:
mysql> CREATE TABLE tmp SELECT IFNULL(1,'test') AS test;
mysql> DESCRIBE tmp;
-------------------------------------------+
| Field | Type | Null | Key | Default | Extra |
-------------------------------------------+
| test | char(4) | | | | |
-------------------------------------------+
In this example, the type of the test column is CHAR(4).
NULLIF(expr1,expr2)
Returns NULL if expr1 = expr2 is true, otherwise returns expr1. This is the same as CASE WHEN expr1 = expr2 THEN NULL ELSE expr1 END.
mysql> SELECT NULLIF(1,1);
-> NULL
mysql> SELECT NULLIF(1,2);
-> 1
Note that MySQL evaluates expr1 twice if the arguments are not equal.

Don't use IFNULL for comparisons (especially not for Joins)
(example:
select aa from a left join b ON IFNULL(a.col,1)=IFNULL(b.col,1)
It's terrible slow (ran for days on two tables with approx 250k rows).
Use <=> (NULL-safe comparison) instead. It did the same job in less than 15 minutes!!

IFNULL is like oracle's NVL function (these should help people searching for NVL() ..)

When using CASE, remember that NULL != NULL, so if you write "WHEN NULL", it will never match. (I guess you have to use IFNULL() instead...)

You can ORDER BY a dynamic column_name parameter using a CASE expression in the ORDER BY clause of the SELECT statement:
CREATE PROCEDURE `orderby`(IN _orderby VARCHAR(50))
BEGIN
SELECT id, first_name, last_name, birthday
FROM table
ORDER BY
-- numeric columns
CASE _orderby WHEN 'id' THEN id END ASC,
CASE orderby WHEN 'desc id' THEN id END DESC,
-- string columns
CASE orderby WHEN 'firstname' THEN first_name WHEN 'last_name' THEN last_name END ASC,
CASE orderby WHEN 'descfirst_name' THEN first_name WHEN 'desc_last_name' THEN last_name END DESC,
-- datetime columns
CASE _orderby WHEN 'birthday' THEN birthday END ASC,
CASE orderby WHEN 'desc birthday' THEN birthday END DESC;
END
Since the CASE expression returns the "compatible aggregated type of all return values", you need to isolate each column type in a separate CASE expression to get the desired result.
If you mixed the columns like
CASE _orderby
WHEN 'id' THEN id
WHEN 'first_name' THEN first_name
...etc...
END ASC
.. both the id and first_name would be returned as a string value, and ids would be sorted as a string to '1,12,2,24,5' and not as integers to '1,2,5,12,24'.
Note that you don't need a "ELSE null" in the CASE expressions, since the CASE expression automatically returns null if there's no match. In that case, you get a "null ASC" in your ORDER BY clause which doesn't affect the sort order. If for instance orderby is 'descfirst_name', the ORDER BY clause evaluates to:
ORDER BY null ASC, null DESC, null ASC, first_name DESC, null ASC, null DESC
Effectively the same as "ORDER BY first_name DESC". You could even add a new set of CASE expressions for a second order column (or more..) if you like.

How can I use mySQL with OC4J

Hello,
I have standalone OC4J and I want to use mySQL database (Oracle is no problem). My data-sources.xml for application (not global data-sources) is:
<data-sources>
<data-source class="com.evermind.sql.DriverManagerDataSource"
     connection-driver="org.gjt.mm.mysql.Driver"
     ejb-location="jdbc/MG_DBDS"
     inactivity-timeout="30"
     location="jdbc/MG_DBCoreDS"
     name="MG_DBDS"
     password=""
     pooled-location="jdbc/MG_DBPooledDS"
     url="jdbc:mysql://127.0.0.1:3306/test"
     username="root"
     xa-location="jdbc/xa/MG_DBXADS"/>
</data-sources>
Deploy return me:
Error initializing data-source 'jdbc/MG_DBCoreDS': DriverManagerDataSource driver 'org.gjt.mm.mysql.Driver' not found
Then I run this command:
java -jar %OC4J_HOME%\admin.jar ormi://192.168.1.14:23791/ admin heslo -application Register -updateDataSource -oldLocation jdbc/MG_DBCoreDS -jar mysql-2.0.11-bin.jar
this action is success and create in OC4J folder lib with jar file mysql-2.0.11-bin.
When I use this configuration in application, I get connection but creating Statement cause SQL Exception - No suitable driver.
When I try to restart OC4J, I get the same message as throught deploy - Error initializing data-source ...
What is go wrong???? Could me help anyone?
Thanks
Libor

pooling solution:
1) put driver mysql.jar into any directory wich described in OC4J application.xml file like
" <library path="D:\j2ee\home\lib">jdev-generated</library>"
2) put a new datasource in data-sources.xml:
<data-sources>
<data-source name="MySqlDS"
location="jdbc/MySqlDS"
class="com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource"
max-connections="100"
min-connections="5"
inactivity-timeout="200"
wait-timeout="10"
username="scott"
password="tiger"
url="jdbc:mysql://localhost:3306/oln?useUnicode=true"/>
</data-sources>
OC4J needs a special pooling class in comparision with other containers. For example, JBoss has own implementation of pooling broker, so pooling is enabled by default.
