[RESOLVED] Conditional parsed variable

[Jon12345]

Sometimes I send people to www.mysite.com/index.php?refid=eminem

Othertimes I send people to www.mysite.com/index.php

My code below is supposed to assist my tracking:

<?php
$target=$_GET['artist'];
$refid=$_GET['refid'];
$offer=2995;
if($refid-true) {
$subid=$refid;
}
else {
$subid="indexpage";
}
?>

What I am trying to do is say if I have passed a variable, I will set $subid to the refid value that was passed along. But if no refid value was passed along, then I will use the value "indexpage".

Is my code corrrect to do this? I used =false but I am not sure about this!

Thanks,

Jon

try using isset() and even combining it with empty (or checking the validity of the refid to make sure it wasn't changed by the user to something invalid).

<?php

if ( ( isset($_GET['refid']) ) && ( !empty($_GET['refid']) ) )
{
	// Refid is set
}
else
{
	// Refid is not set. Do something different
}

?>

That was exactly what I needed. Thank you. 🙂
