MySQL Database Index Page
I'm looking for a way to create an index of my MySQL database tables. The basic concept is to have a list of the table names on the left hand side of the page. Clicking on a name will bring up the database contents (repeated to display each record) o nthe right hand side. Any idea or tutorial on how to accomplish this? Thanks!
Okay, great! I worked with it and modified it a tiny bit to insert a DW table into the results. But when I Insert the php script into each table block, it displays only the first column of data, not the rest.
<?php
// connect to database
$conn = new mysqli('localhost' , 'user' , 'pw' , 'dbase');
?>
<?php
// get table names from database
$listTables = $conn->query("show tables") or die($conn->error);
// get table names from link
$table_name = $_GET['table_name'];
if(isset($table_name)) {
$sql = 'SELECT * FROM '.$table_name.'';
$getTableList = $conn->query($sql) or die($conn->error);
?>

Sending colour from a JSP page into a MySQL database field
Dear All,
I am working on trying to send different colours into a MySQL database field from a JSP page.
This is so that I can represent different pieces of data on my webpage tables in different colours providing status depending on the user request.
What is the best way to write JSP code for this?
thanks,

There is idea how can resolve this problem

Strange problem with MySQL database
Hello,
I'm totally puzzled by a strange error occurring with PHP/MySQL on my website... I hope someone has got an idea of what's going on and can let me know.
In short, I have a MySQL database set up on the remote server where the website is hosted. Some pages of my website access this database with PHP.
If the website is viewed with a browser in Windows (Firefox), it works well, the database data appear on the pages.
If the website is viewed with a browser on Mac OS (Firefox, Safari), it doesn't work: the database isn't accessed, I get no error, just everything on the page below my PHP code is missing.
I've attached two screenshots to show this. The website URL is: http://www.cerc.co.uk/CERC/v02/
The pages were this occurs are: the home page (index.php and alternative index2.php), the Abous us/News page and the About us/News/Archives page.
I really don't get where my mistake is. I would like to keep the remote server connexion details outside the root folder, but I guess that if there is no solution to this problem, then I'll have to move it back (I think it might have worked like that).
Thanks in advance for any comment,
Emilie
More details
I'm using DW CS4 on Windows XP emulated via VMware on Mac OS 10.5 (don't ask why, I wasn't given any choice). I've set up a localhost server on XP via XAMP and the news database is also there.
Because I'm currently flipping often between the testing server and the remote server, I quickly got fed up to change all the time the connexion mode to the database (localhost or remote server) and have to resynchronise the files each time. Hence I decided to automate a bit the way the database is connected to.
1. These 4 HTML pages with PHP code have got the below two lines when the PHP code starts:
$pathpfx = "../.."; // see mysqlconnexion.php
include('assets_design/php/mysqlconnexion.php');
2. mysqlconnexion.php (see code below) calls a "connexion" file (in PHP) depending on the value of one parameter ($conxchoice). If $conxchoice = 1, the "connexion" file on the localhost is called. If $conxchoice = 2, the "connexion" file on the remote server is called. I've stored the appropriate version of mysqlconnexion.php on the localhost and the remote server (and I have checked it a million of times, they're in the right place).
<?php
// This code is called by and therefore included in the code of some PHP pages,
// independently of where the pages are located within the website folder.
// - Connexion to local server: I couldn't get the function include_once to work
// with a relative path, hence the use of an absolute path.
// - Connexion to host server: I couldn't get the function include_once to work
// with an absolute path, hence the use of a relative path. This leads to the
// following problem: the path of conxsrv.php needs to be adapted to the
// position of the calling PHP page within the website, in order for
// conxsrv.php to be found on the server (it is located outside the website
// root folder). The variable $pathpfx is used for this purpose.
$conxchoice = 2; // connect to 1 = testing server, 2 = host server
// Connexion to database
if ( $conxchoice == 1 )
{ include_once('C:\xampp\htdocs\CERC\assets_testing_server_only\conxloc.php'); }
if ( $conxchoice == 2 )
{ include_once("$pathpfx/cgi-bin/sqlconx/conxsrv.php"); }
?>
I would guess that a first hint of solution lies in the comment block, but I've really tried everything I could think of to work with relative path/absolute path respectively, unsuccessfully.
3. The "connexion" file looks like:
<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_conx = "aaa";
$database_conx = "bbb";
$username_conx = "ccc";
$password_conx = "ddd";
$conx = mysql_pconnect($hostname_conx, $username_conx, $password_conx) or trigger_error(mysql_error(),E_USER_ERROR);
?>
With aaa, bbb, ccc and ddd the appropriate value depending on the file. The # lines were introduced by DW when these files were created (I've then changed the variable names and moved the files to another place).
ScreenshotsWell, my question has actually not been answered yet but the problem, as strangely as it appeared, has now disappeared. Best but scariest of all, I didn't do anything. Weird.
Hope it never comes back,

Accessing MySql database in jsp
hi everyone!!!
i m new to java with little knowledge of jsp.
i want to access mysql database in jsp to develop a web page.
i have jdk and mysql installed and these are working. what are other requirements and how to do this.
plz help.
OS: MS Windows XP/ Fedora 10Learn JDBC API: [http://java.sun.com/docs/books/tutorial/jdbc/index.html]. Create a DAO class which uses JDBC to interact with Java and takes or returns the desired data in form of DTO's. Use and test it as a plain vanilla Java application with a main() method. This require a JDBC driver (a concrete implementation of the JDBC API) in the classpath. MySQL offers JDBC drivers as download at their homepage, it is called "Connector/J".
Once you got the JDBC part to work, create a Servlet class which holds an instance of the DAO class and uses its methods to interact with the database. In the doGet() you can place logic to preload data from the DAO class for display. In the doPost() you can place logic to process data for create, update or delete using the DAO class. Finally let it forward the request to a JSP.
In the JSP you can use JSTL/EL to display data. For tabular view you may find the JSTL c:forEach useful. For plain display, just use EL the usual way. -

You can also enable an SSL HTTP/1.1 Connector on port 8443 by
following the instructions below and uncommenting the second Connector
entry. SSL support requires the following steps (see the SSL Config
HOWTO in the Tomcat 4.0 documentation bundle for more detailed
instructions):
* Download and install JSSE 1.0.2 or later, and put the JAR files
into "$JAVA_HOME/jre/lib/ext".
* Execute:
%JAVA_HOME%\bin\keytool -genkey -alias tomcat -keyalg RSA (Windows)

with a password value of "changeit" for both the certificate and
the keystore itself.
By default, DNS lookups are enabled when a web application calls
request.getRemoteHost(). This can have an adverse impact on
performance, so you can disable it by setting the
"enableLookups" attribute to "false". When DNS lookups are disabled,
request.getRemoteHost() will return the String version of the
IP address of the remote client.

ignored in both cases.
maxActiveSessions: If 0 or greater, having too many active
sessions will result in some being swapped out. minIdleSwap
limits this. -1 means unlimited sessions are allowed.
0 means sessions will almost always be swapped out after
use - this will be noticeably slow for your users.
minIdleSwap: Sessions must be idle for at least this long
(in seconds) before they will be swapped out due to
maxActiveSessions. This avoids thrashing when the site is
highly active. -1 or 0 means there is no minimum - sessions
can be swapped out at any time.
maxIdleSwap: Sessions will be swapped out if idle for this
long (in seconds). If minIdleSwap is higher, then it will
override this. This isn't exact: it is checked periodically.
-1 means sessions won't be swapped out for this reason,
although they may be swapped out for maxActiveSessions.
If set to >= 0, guarantees that all sessions found in the
Store will be loaded on startup.
maxIdleBackup: Sessions will be backed up (saved to the Store,
but left in active memory) if idle for this long (in seconds),
and all sessions found in the Store will be loaded on startup.
If set to -1 sessions will not be backed up, 0 means they
should be backed up shortly after being used.
To clear sessions from the Store, set maxActiveSessions, maxIdleSwap,
and minIdleBackup all to -1, saveOnRestart to false, then restart
Catalina.

Is there anyone who can help me to design a index page
Hi guys
I would like to design a index page like this site :
http://www.hostplate.com
Is there anyone who can help me ?Your example site is built with WordPress (a popular open source framework).
You'll need to have a good working knowledge of HTML, CSS and some familiarity with PHP code & the ability to set-up a MySql database on your server. The good news is that there is a wealth of on-line information available to you.

Populate Livecycle PDF from mySQL database using PHP
I'm trying to set up a database of loan agreements, where users will submit a form through Acrobat and their information will be stored in a mySQL database. Later, they can go back and download the PDF, which will be repopulated with their data in the mySQL db.
I made the form in Livecycle Designer and submit the information through HTTP POST. I can easily get the information from the form into the database...my only problem is getting that information back out into the PDF.
What would allow me to write back to the PDF, preferably using PHP? What kind of syntax would that require?
Thanks!I have a vital form that clients fill out, which is passed to many people in the company along the workflow. The form is a Planner and we have in the following PDF, Word Doc..
Well before, the Planner.pdf was originally created in Word, since most people have access to Word.. but evolved to a PDF form created from the Word Doc via Adobe LiveCycle Designer 8.0 w/ User Rights enabled so that the form could be filled out and saved using Adobe Reader.. which was a step better than Word.. being that it is free. But this needed to be easier and more to the point b/c some clients don't particularly like installing the latest version of Reader, even if you provide them the link. Nor do they like saving the form, filling the form, and attaching the form to send back.
My goal is to have the client fill an HTML version of the form, submit and be done with it, but everyone in the workflow be able to easily receive the filled Planner as a PDF form.
So some months ago I ran into this post Chris Trip, "Populate Livecycle PDF from mySQL database using PHP" #8, 22 Sep 2007 4:37 pm
which uses the command line Win32 pdftk.exe to merge an FDF file into an existing PDF on the remote server, and serve this to whoever.
My problem was with shared hosting and having the ability to use the Win32 pdftk.exe along with PHP which is predominantly used on Linux boxes. And we used a Linux box.
so i created the following unorthodox method, which a client fills the HTML version of the Planner, all field values are INSERTED into a table in MySQL DB, I and all filled planners that have been filled by clients to date can be viewed from a repository page where an XML file is served up of the corresponding client, but someone would have to have Acrobat Professional, to import the form data from the XML file into a blank form.. altoughh this is simple for me.. I have the PHP file already created so that when a Planner is filled and client submits. >> the an email is sent to me with a table row from the repository of the client name, #, email, and a link to d-load the XML file,
But I also have the PHP files created so that the Planner can be sent to by email to various people in the workflow with certain fileds ommitted they they do not need to see, but instead of the XML file beiong served up i need the filled PDF Planner to be served.
I can do this locally with ease on a testing server, but I am currently trying to use another host that uses cross-platform compatibility so i can use PHP and the pdftk.exe to achieve this, as that is why I am having to serve up an XML file b/c we use a Linux server for our website, and cant execute the exe.
Now that I am testing the other server (cross-platform host), just to use them to do the PDF handling (and it's only $5 per month) I am having problems with getting READ, WRITE, EXECUTE permissions..
Si guess a good question to ask is can PHP do the same procedure as the pdftk.exe, and i can eleminate it.
or how in the heck can i get this data from the DB into a blank PDF form, like i have described??

here i'm trying to connect to Users mysql database (i use Tomcat 4.1 and mysql servers and clients 4.0.1-alpha)
where is the problem ? when i run this servlet (http://localhost:8080/example/servlet/LoginServletJDBC ) it works ;
BUT when i type an username and a password (any user&pass) my servlet doesn't connect to the database (become a infinite loop without output ; i mean no any errors and exceptions)
i try other think : i changed the database with unexisting database and the result was that i was expected (Unknow database 'unexistingdatabase' )
what i miss ?
please... can anyone help me...
thank`s in advanceThe wireless security setting that the Actiontec modem/router is using may be different...and not compatible....than the setting that the Comcast product was using.
If you think that might the case, and you have the time to troubleshoot......
Temporarily, turn off the wireless security on the Actiontec modem/router
Reset an AirPort Express back to default settings, then see if it will connect using no security and allow an Internet connection when you do the Ethernet port test in the post above again.
If the AirPort Express cannot connect correctly using no security on the wireless network.....then it is a no brainer to know that it will never connect when security is enabled. So, if the AirPort will not connect using no security, you may have an incompatibility issue between the Actiontec and Apple products.
However, if the AirPort Express connects OK with no security, then this tells you that you will need to use a different setting for security on the Actiontec...the same that the Comcast router was using before.....so the Express will have a better chance of connecting.
That setting would be something like WPA/WPA2 Personal, or the same setting stated another way would be WPA-PSK-TKIP. -

Problem with connection in Mysql database in struts application
Helllo
i've just started learning struts for my new project where i'm having problem in accessing mysql database
the datasource being defined in struts-config.xml is as follows:

<set-property property="readOnly" value="false" />
<set-property property="autoCommit" value="true" />
<set-property property="loginTimeout" value="" />
</data-source>
</data-sources>as i run the application
it gives the errors HTTP status 404-Servlet action is not available
Thx in advancestudent-java wrote:

HTTP 404 is a "Page not found" error. The request URL is simply wrong. Either there's a typo in the URL, or there is a typo in the servlet mapping, or the servlet is not there where you think. -

I have never had to open more than one MySQL database from within the same website before, but I do now. The website I have is designed where all the content comes from within the main database. I am building an Inventory system that I want within it's own database, in the event I would ever need to move the application to another server or something, I don't want this data residing in the main database.
Currently, I open the database connection from within a file called "common.php" that resides in a directory called "lib" that can be accessed from the root directory. Below is the proposed code that would be placed within the "common.php" file:
// Define Database Variables
$dbserver = "127.0.0.1";
$dbuser = array('clevelan_user1', 'clevelan_user2');
$dbpass = array('P@ssw0rd', 'P@ssw0rd2');
$dbname = array('clevelan_database1', 'clevelan_database2');
// Start Session
session_start();
// Connect to Databases
connectdb($dbserver, $dbuser[0], $dbpass[0], $dbname[0]);
connectdb2($dbserver, $dbuser[1], $dbpass[1], $dbname[1]);
// Database 1 Connection
function connectdb($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db
global $connection;
$connection = @mysql_connect($dbserver, $dbuser, $dbpass) or die ("could not connect to server");
$db = @mysql_select_db($dbname, $connection) or die ("could not select databsase");
return $connection;
// Database 2 Connection
function connectdb2($dbserver, $dbuser, $dbpass, $dbname) {
// connects to db
global $connection2;
$connection2 = @mysql_connect($dbserver, $dbuser, $dbpass) or die ("could not connect to server");
$db2 = @mysql_select_db($dbname, $connection2) or die ("could not select databsase");
return $connection2;
//End of Code Within the "common.php"
From within any page of the website, I want to access both connections by placing an include at the top of each page:
include_once("lib/common.php");
Currently, when I run the code above, any page within the website (the home page) provides error messages with regards to database connectivity (the pages are looking for there content from within the second database. It's as if the second database is the only database seen by the website.
I need help figuring out how I can have two MySQL databases open at the same time (the second database will only be open for short periods of time and then closed). But the main database is always open.Create one project using one copy of the exact tables.
create 2 different sessions.xml files each pointing to the same project. Set the login information in the sessions.xml files.
That should work fine.

How to get the data from mysql database which is being accessed by a PHP application and process the data locally in adobe air application and finally commit the changes back in to mysql database through the PHP application.
If the data is on a remote server (for example, PHP running on a web server, talking to a MySQL server) then you do this in an AIR application the same way you would do it with any Flex application (or ajax application, if you're building your AIR app in HTML/JS).
That's a broad answer, but in fact there are lots of ways to communicate between Flex and PHP. The most common and best in most cases is to use AMFPHP (http://amfphp.org/) or the new ZEND AMF support in the Zend Framework.
This page is a good starting point for learning about Flex and PHP communication:
http://www.adobe.com/devnet/flex/flex_php.html
Also, in Flash Builder 4 they've added a lot of remote-data-connection functionality, including a lot that's designed for PHP. Take a look at the Flash Builder 4 public beta for more on that: http://labs.adobe.com/technologies/flashbuilder4/ -
How to get data into the mySQL database?
First some background.
I have a website that has outgrown its designed dimensions and is a huge burden to maintain. See PPBM5 Benchmark
There is a lot of maintenance work involved, so I'm investigating a PHP/MySQL approach to easen the burden and to add functionality to the site. With the current Excel based structure and over 420 entries, it is cumbersome for me to maintain, but also for users to find what they need.
A MySQL based dynamic structure is a lot easier and offers vastly more selection capabilities, like selecting only records that meet specific criteria.
Data submission is done with a form, that contains most of the relevant data, but the drawack is that people submitting their data are often not technically inclined, give wrong answers due to a lack of understanding or making typo's. The test results are attached in one or two separate .txt files, but often they have not read the instructions correctly or did something wrong, so these attached .txt files can not be trusted automatically, they have to be checked before inclusion.
These were my initial thoughts:
1. Data collection:
To avoid spending all our energy and time on correcting typo's, getting missing data, correcting errors, I am investigating the use of CPU-Z in Ghost mode to create a .txt or .html file that contains all relevant hardware info we need and even more. It gives all the info we currently have, but adds data like number of memory sticks, DDR timings, stock clock speed and BCLK setting, video card info and VRAM size, etc.
To see what I mean, run CPU-Z, go to the About tab and press the Save Report button and look at the results.
This can all be done without user intervention in an automatic way, but maybe I need to add an Auto-It file to the test to make it all run as desired.
If this works and I'm able to extract the relevant data from the created file and can insert it into the database, we may be in business for the next version of PPBM5.5 or PPBM6. It does require a modification to the instructions, making them a lot easier, because there is less data to fill out.
2. Data submission:
The submission form can be simplified if the CPU-Z data can be used. We have to create an automatic way to attach the created .html file from CPU-Z to the submission form and we have to streamline the Output.txt and Output-MPE.txt files to be more easily included in the 'form.lib.php' file. It currently is manual labor and very time consuming.
3. Adding to Database:
I have to find a way to create database records from the Gmail forms I receive. All incoming mail messages need to be checked on relevancy and if relevant, need to be added automatically to the database and then offered for approval before final inclusion in the database. Data included in the database will then include submission date and time, Email address, IP address used, plus links to the files submitted and available on the website.
4. Publication of the database:
After approval of new records from step 3, all updates will be automatically applied to the database and accessible for users. I do not yet intend to introduce a user account , requesting login before all functionality is accessible. Too much trouble and administration.
Queries should be possible on things like CPU (check box), so include 17-920, i7-930, i7-950 but exclude i7-980X and i7-990X, Size of memory (check box), Overclocked (boolean, yes, no), SSD as OS disk, and similar options.
The biggest problem is to keep the color grading and statistical indicators (Top, D9, Q3, Med, Q1 and D1) intact on dynamically generated queries. Say you make a query which results in 20 observations, this should show the related colors and legends. Next query results in 48 observations and of course the color grading and legends do need to reflect that. Question in my mind, does the RPI remain constant, independent of the query or does that need to be recalculated on the basis of the query?
Next thing is to allow a user to select a specific observation and by simply clicking on it be shown, in a separate window (detail page) or accordion, all the CPU-Z related information about the hardware.
The graphs, Top-20 and MPE Gains, need to be dynamically adjusted, based on the query used.
5. Ideally, external links:
In an ideal situation, one could link the CPU-Z data to external price databases, looking up current prices for CPU, memory, video card, disks, raid controller, etc. to get instant BFTB charts, based on the query made. But that is the next step.
Situation now:
I have a MySQL database that is easily updated with the new submissions. Simply create a .CSV flie from the submitted forms and import that into the database. The bulk of the initial work is done.Lots remain to be done as you can see above, but that is for a later time.
Question:
I have this table, that needs to be filled with data in the submitted and attached files. Mr. X submitted his data and can be uniquely identified by his "Ref_ID". He attached one or two files in .TXT format with the relevant test data. These files are stored on the server with a concatenated name:
"Ref_ID","-","filename"
Say his Ref-ID is: 20110204-6cf5 and his submitted file is called: Output(99).txt then the file can be found on the server as
20110204-6cf5-Output(99).txt
I need to be able to open that comma delimited file, the contents may look like this: "439","1036","819","531" and insert these contents into the relevant record and fields.
Graphically,
is what I want to achieve.
This being my first exposure to PHP/MySQL, you can imagine I'm not clear on how to go from here.
Added complication is that I actually have 5 numbers to insert per record and two calculated fields, Total Score and RPI should be calculated fields. Haven't yet figured out how to handle calculated fields, maybe only in the PHP/HTML code and not in the database.
I hope someone can help me.You do have a very complex looking site and may need several tables in mysql to handle all that data. If you knew to phpmysql I would suggest taking a look at this tutorial it will help get you started in understanding how to $_GET info from a database and also how to $_POST data to a database. I am no expert just learning myself and I found this very helpful. This is the link http://www.adobe.com/devnet/dreamweaver/articles/first_dynamic_site_pt1.html
There are also many tutorials on Youtube to help build a CMS Content Management Site I would suggest the following: -
http://www.youtube.com/user/phpacademy
http://www.youtube.com/user/betterphp
http://www.youtube.com/user/flashbuilding
And many more on my channel here

CMS's are easier to maintain, add edit and delete content.
I have also recently bought a Book by David Powers Training from the Source very helpful.
Anyway hope you get it sorted.
