Re: [PHP] Session Variable Problem

Thanks again for all the help, however the plot thickens.

I have put:

<?php if(!isset($_SESSION)) {
    session_start();
 }
 if (isset($_POST['lend_fname'])){
$_SESSION['lend_fname']=stripslashes($_POST['lend_fname']);
}
if (isset($_POST['lend_lname'])){
$_SESSION['lend_lname']=stripslashes($_POST['lend_lname']);
}
if (isset($_POST['lend_street'])){
$_SESSION['lend_street']=stripslashes($_POST['lend_street']);
}
if (isset($_POST['lend_city'])){
$_SESSION['lend_city']=stripslashes($_POST['lend_city']);
}
if (isset($_POST['lend_state'])){
$_SESSION['lend_state']=stripslashes($_POST['lend_state']);
}
if (isset($_POST['lend_lname'])){
$_SESSION['lend_zip']=stripslashes($_POST['lend_zip']);
}
if (isset($_POST['lend_email'])){
$_SESSION['lend_email']=stripslashes($_POST['lend_email']);
}
if (isset($_POST['lend_phone'])){
$_SESSION['lend_phone']=stripslashes($_POST['lend_phone']);
}

?>

On the first page, Now what happens is it only sticks to the first two 
(lend_fname and lend_lname), the others still get lost. Any idea how or why 
the exact code works differently?

Thanks Again.
