Using RAND() in php

Hello,
I need some assistence using this rand() function in php.
I have one mysql database and I want to get 4 items randomly,
but sometimes I get duplicated items.
how can I avoid this?
also, shouldn't I count the total items in database and then
use the random function?
this is the piece of code
$query = "SELECT id, titulo, icone FROM texto WHERE homepage
LIKE 'sim' ORDER BY RAND() LIMIT 4";
Thanks!

Use the DISTINCT keyword, like this:
$query = "SELECT DISTINCT id, titulo, icone FROM texto WHERE
homepage
LIKE 'sim' ORDER
BY RAND() LIMIT 4";
then each of the four will be distinct.

How to use Rand() (ANSI Function)as such in Oracle

I need to use Rand() function as such in ANSI format in oracle how to use it.
I don't want to use the available DBMS_RANDOM.RANDOM(), i want to use ANSI Function as such in Oracle
Please help me

I don't want to use the available DBMS_RANDOM.RANDOM()Whats wrong with dbms_andom?
In any case you can simply write a function wrapper to have same functionality as rand():
SQL> create or replace function rand (max_val int default 32767)
return int
as
begin
return dbms_random.value (0, max_val);
end rand;
Function created.
SQL> select rand(50) from dual
RAND(50)
44
1 row selected.

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 ?

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.

How can i use C/Javascript/php/Java in flex?

can i embed these language into my flex project?
since i have to check harddisk space, free memory remain. Also, i need to check the pixel of photos before the photos becoming bitmapdata
please help~

You can't. Why do you want to do this?
saipanBETTY0509 wrote:

I think what this means is "I want to check to see how much hard disk space is available. Also, I need to check the pixel dimensions of an image."
Is that right?
There is no way in the Flash Player (as far as I know) that you can determine the amount of free disk space. However, in AIR you can use air.File.applicationStorageDirectory.spaceAvailable to determine the storage space available in the application storage directory.
As far as determining the dimensions of an image, there are plenty of good resources out there on that. Maybe this one will be helpful to you?

How to use cursor in php?

for example:
CURSOR CUR_ORDER IS
select distinct a.sales_branch segment2,a.order_number,
a.delivery_id,
a.sold_to_customer_id customer_id,
a.bill_to_customer_id,
a.ship_to_customer_id,
a.purchase_order,to_char(a.ordered_date,'yyyy-mm-dd') order_date
from vv_ar_temp_tl a;
how to use it in php program?

Hi,
I do not know what exactly is Your question about. I'll try to give an overview:
1. "CURSOR CUR_ORDER IS" is PL/SQL syntax, not PHP
2. result of oci_parse call is in fact a CURSOR, so I think You already know how to use it.
3. if Your question is on how to pass cursor between PL/SQL and PHP, I use:
a) PL/SQL procedure:
CREATE OR REPLACE
PROCEDURE TEST_P (PO_REF_CURSOR OUT SYS_REFCURSOR) AS
BEGIN
OPEN PO_REF_CURSOR FOR -- Opens ref cursor for query
SELECT OBJECT_NAME, OBJECT_TYPE FROM USER_OBJECTS WHERE ROWNUM <= 5;
END;
b) in PHP:
$conn = ocinlogon($database_user, $database_passwd, $database); // connect database
$outrefc = ocinewcursor($conn); //Declare cursor variable
$mycursor = ociparse ($conn, 'begin test_p(:curs); end;'); // prepare procedure call
ocibindbyname($mycursor, ':curs', $outrefc, -1, OCI_B_CURSOR); // bind procedure parameters
$ret = ociexecute($mycursor); // Execute function
$ret = ociexecute($outrefc); // Execute cursor
$nrows = ocifetchstatement($outrefc, $data); // fetch data from cursor
ocifreestatement($mycursor); // close procedure call
ocifreestatement($outrefc); // close cursor
ocilogoff($conn); // close database connection
var_dump($data); // show content fo $data variable
Now $data contains arrays of columns with arrays of rows from query.
Hope it helps You,

Pawel

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

Is there any way to use the bundled PHP compiler without web sharing on?

Is there any way to use the bundled PHP compiler without Web Sharing on? Is there a way to make sure Web Sharing only allows local access so others on the network cannot access it? Any other easy way to get a PHP compiler on a Mac? I currently run Mac OS X 10.7.4. Any other security issues that might pop up from leaving Web Sharing on? Basically I just want a local PHP compiler so I can do some coding.

You can use another router as an 'extender' (I know that this will work seemlessly with AirPort Extemes and AirPort Express's - you'll have to check with your router manufacturer to determine what they recommend for range extenders).
You may also want to take a look at this link - http://www.wi-fiplanet.com/tutorials/7-tips-to-increase-wi-fi-performance.html - it may offer some tips.

Creating a file on server, using Flash AS3 + PHP

I have a very simple PHP script that creates a new file on my server using a random number for the file name (e.g., 412561.txt). When I load the script directly from a browser, it works. But when I load the script from a very simple Flash (AS3) script, it does not work (i.e., doesn't create a file). The Flash script and PHP script are both in the same directory. Permissions on the directory and its content are 755. Temporarily setting those permissions to 777 does not solve the problem (i.e., PHP still doesn't create file when called via Flash).
Here is my phpinfo.
Here is the PHP file.
The contents of the PHP file are:
<?php
error_reporting(E_ALL);
ini_set("display_errors", 1);
$RandomNumber = rand(1,1000000);
$filename = "$RandomNumber" . ".txt";
$filecontent = "This is the content of the file.";
if(file_exists($filename))
          {$myTextFileHandler = fopen($filename,"r+"); }
else
          {$myTextFileHandler = fopen($filename,"w"); }
if($myTextFileHandler)
          {$writeInTxtFile = @fwrite($myTextFileHandler,"$filecontent");}
fclose($myTextFileHandler);
?>
Here is the html container for the Flash script. The Flash script features a single button which calls the PHP script when pressed. In case it helps, here is the raw Flash file itself. The code of the Flash script is as follows:
stop();
var varLoader:URLLoader = new URLLoader;
var varURL:URLRequest = new URLRequest("http://www.jasonfinley.com/research/testing/TestingSaveData.php");
btnSave.addEventListener(MouseEvent.CLICK,fxnSave);
function fxnSave(event:MouseEvent):void{
          btnSave.enabled=false;
          varLoader.load(varURL);
Directory listing is enabled at the parent directory here, so you can see there when a new text file is created or not. (Um, if this is a security disaster, please let me know!)
Can anyone please help me understand why this isn't working and how I can fix it? Thank you
~jason

#1, Yes that is a security risk, please disable directory index viewing.
#2, Always validate. I see no issue with the code you're using but clearly it's not working. The way you find out is your trusty errors.
Make a new document (or paste this into your existing) where a button with the instance name btnSave is on screen:
// import required libs
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.events.IOErrorEvent;
import flash.events.MouseEvent;
import flash.events.SecurityErrorEvent;
import flash.text.TextField;
// assign handler
btnSave.addEventListener(MouseEvent.CLICK, fxnSave);
// make a textfield to display status
var tf:TextField = new TextField();
addChild(tf);
tf.width = stage.stageWidth;
tf.height = 300;
tf.multiline = true;
tf.wordWrap = true;
tf.selectable = false;
tf.text = "Loading...\n";
// just making sure the textfield is below the button
this.swapChildren(tf,btnSave);
function fxnSave(event:MouseEvent):void
    // disable button
    event.currentTarget.enabled = false;
    // new loader
    var varLoader:URLLoader = new URLLoader();
    // listen for load success
    varLoader.addEventListener(Event.COMPLETE, _onCompleteHandler);
    // listen for general errors
    varLoader.addEventListener(IOErrorEvent.IO_ERROR, _onErrorHandler);
    // listen for security / cross-domain errors
    varLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, _onErrorHandler);
    // perform load
    varLoader.load(new URLRequest("http://www.jasonfinley.com/research/testing/TestingSaveData.php"));
// complete handler
function _onCompleteHandler(e:Event):void
    tf.appendText("Load complete: " + e);
// error handler
function _onErrorHandler(e:Event)
    if (e.type == SecurityErrorEvent.SECURITY_ERROR)
        tf.appendText("Load failed, Security error: " + e + " type[" + e.type + "]");
    else if (e.type == IOErrorEvent.IO_ERROR)
        tf.appendText("Load failed, IO error: " + e + " type[" + e.type + "]");
I get a Event.COMPLETE for mine, so the PHP script is definitely firing. Change the URL to something invalid and you'll see the IOErrorEvent fire off right away.
That leaves you to diagnose the PHP script. Check your error_log and see what is going wrong. You're suppressing errors on your file write which doesn't help you locate the issue saving the file. If you want to handle errors yourself you should do the usual try/catch and handle the error yourself (write a debug log file, anything).

How do I set the PATH to use ImageMagick under PHP on my Server?

Hi,
I have the ImageMagick binaries installed. They are working in the terminal.
But when I try to use it out of a php script on the webserver, it cant find the DYLD_LIBRARY_PATH.
The manual says:
Set the MAGICK_HOME environment variable to the path where you extracted the ImageMagick files. For example:
export MAGICK_HOME="$HOME/ImageMagick-6.3.7"
If the bin subdirectory of the extracted package is not already in your executable search path, add it to your PATH environment variable. For example:
export PATH="$MAGICK_HOME/bin:$PATH"
Set the DYLD_LIBRARY_PATH environment variable:
export DYLD_LIBRARY_PATH="$MAGICK_HOME/lib"
I can do all this in the Terminal, but how and where do I set it, that it also works with the scripts on the webserver?
Thanks and Regards,
JO

Joachim,
I have not tested any of this but...
If you are just using the default Mac OS X Server install of Apache and the PHP module, then Apache's path is /usr/bin:/bin:/usr/sbin:/sbin (when running under the user:group=www:www). Basically, if the server is running under that user and PHP inherits the basic PATH of that user's shell, then anything linked into those directories should be available to the scripts, i.e. link your ImagMagick bin and lib paths into /usr 's directories. See 'man ln' in Terminal. User www doesn't have a defined shell, though, so I don't know where the PATH comes from.
Alternatively, you might be able to use Apache's env_module (on by default) to manipulate the PATH environment variable in a config file. See Apache's manual on environment variables.
Another means is to utilize 'suexec' in Apache and switch the user:group of CGI execution, etc. to a actual user with a definable .bash_profile (or whatever shell you are using). There are security concerns with this. See Apache's manual on suexec. You may want to also consider compiling PHP as CGI.
BTW: the new version of PHP has some new experimental native ImageMagick libraries built in. I assume it looks for the binaries in the usual places and/or may need to be compiled with their paths during ./configure.

Anyone use Flex with php for file upload? PHP Notice: Undefined index: Filedata

My code works. It uploads the file and inputs the file name into a database, but I can't shake this php notice. I think php is looking for multipart/form-data from the HTML form tag.
<form action="upload.php" enctype="multipart/form-data"/>
But I am using flex. The multipart/form-data info is sent as the second default argument of the upload() function. Does anyone have experience with this? Thanks.

ANy help would be thankful !

How to send the email without using server side (Php, java)

How to send the (Run time image or file) Email & Attachment in Flex web application. without using php, java.

Well, at some point your email needs to be handed over to an SMTP server. It's a fair amount of work, but if you want to just send an email you could open a socket to a mail server's SMTP port and follow the SMTP protocols to send your email.

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.

Dear,
If you want to use the code.
first you can write your code in a subroutine in module pool program 1
and then you can use it from module pool program 2 by
perform subroutine_name(program_name)
using P_1
changing C_1
if you wan to use one module pool data into other module pool.
so that is another requirement.
