$cardtype = @$_GET['type'];
$_SESSION['cardtype'] = $cardtype;
    PHP:
    
$cardtype = @$_GET['type'];
if($cardtype=="new"){	
	$_SESSION['cardtype'] = "new";
}
if($cardtype=="replace"){	
	$_SESSION['cardtype'] = "replace";
}
if($cardtype=="create"){	
	$_SESSION['cardtype'] = "create";
}
    PHP:
    why the session in first code cannot hold the value of $cardtype.
    when i try to change the code to the second code, then the session can hold the value of $cardtype to the following page. it is weird.
    i wonder why the first code cannot display the value? it should be can be displayed.

    Make sure you start with session_start();

    If the PHP directive register_globals is set to on then session values will also be made into variables. try to change different name for session.

    example :

    $_session[ctype] = $cardtype;

    ok the reason is that on the first code the session variable is set to blank if you go to that page and $_GET['type'] is not set . where as the second one if its not set to something specific it doesnt write to the session variable

    Make sure you have the value in $_GET['type'] and remove @ before this line.
