Get round register_globals

[simonp]

We trying to stop using register_globals but this code we have doesn't work without it. What would we need to change?

 

// only validate form when form is submitted
if(isset($submit_button)){
$error_msg='';
if($pagerName=='') {
	$error_msg.="<li>Please tell us your name</li>";
}
	if($pagerPhone=='') {
	$error_msg.="<li>Please tell us telephone number</li>";
}

 

Thanks!

not really sure! What I don't get is how PHP knows what any of them are as they are passed from a form??

but that is not recommended. instead, assign variables that you want:

$submit_button = $_POST['submit_button'];

You can pass session variables from one page to another.

 

Place session_start() at the start of each file that uses them.

This worked a treat - I knew it was something simple

 

Thanks all.
