Help with PHP Variable

[Scolez]

 

 

A variable is declared in index.php when the page loads (random number). When the user clicks on a link, I need to make a MySQL query with the variable. How would I do this?

 

When I ran the code with javascript ($.get("run.php");return false;) it doesn't recognize the variable.

 

I think I have to use Ajax but I just really dont know how that works, I just started PHP and MySQL a few days ago.

 

Help?

The description of your problem doesn't really help. Can you post some code and try again?

If I'm understanding correctly, you need to send the random number back to the server when the user clicks the link? Something like this?

<?php

if (isset($_GET['rn']))
{
    mysql_query('SELECT * FROM table WHERE rn = '.$_GET['rn']);
}


$rn = rand();

echo '<a href="?rn='.$rn.'">random number link</a>';

?>

$rn = rand();

<?php

if (isset($_GET['rn']))
{
mysql_query('SELECT * FROM table WHERE rn = '.$_GET['rn']);
}

echo '<a href="?rn='.$rn.'">random number link</a>';
?>

 

 

try this re-arrange code

Alright guys, I've figured it out. I used Ajax to send the variable with the request. Thanks for all your help
