[RESOLVED] Post Data

[james3302]

I am keeping up a website that someone else made and I updated from PHP 4 to php5.2.4. He has a hyperlink that gos to here.

http://sega81.com/php/live/multiplexer.php4?wc=&wc=ADAM

Where ADAM is the information that is being passed to the multiplexer.php4 file.

The file iteself referneces that variable as $wc.

I remember that when sending post data using a form you use
$wc = $_POST['wc'];

and then you can reference it using $wc. But This does not work in this instance.

nevermind

$wc = $_GET['wc'];

[halojoy]

when you have
variables in URL
it is called $_GET['varname']
so .......

<?php

// this fails to give $wc a value, if no GET
// but else it will work
$wc = $_GET['wc'];

// in case this variable may not be set
// we usually do this assign/check
// if is isset then $wc= GET, else $wc = false
$wc = isset($_GET['wc']) ?   $_GET['wc'] : false;

if( $wc ){
    // do
}
?>
