PHP - using variable to limit output in url problem

[NTLDR]

Take a look at the globalize() function in includes/functions.php and how vB uses it. For the above example with state:

PHP Code:

globalize($_REQUEST, array('state' => STR_NOHTML)); 


Basicly means, take the variable index with the name state, from the $_REQUEST array (ie $_REQUEST['state']) make it a string with HTML removed with the variablt name $state
