How to display cookie value if exists OR session value if cookie doesn't exist
I'm trying do display a value on my page. If a cookie exists for this value, i want that displayed. If not, i want a session variable displayed. I want these to be the default value on a text field, but to start with, for simplicity, i'm just trying to get them to display on the page how i need them.
My current code doesn't seem to work. It outputs a '1', whatever the conditions are.
Here's the code.
<p>if cookie then here, if session, then here:
<?php echo (((isset($_COOKIE["RememberMeUN"]))?$_COOKIE["RememberMeUN"]:"") || ((isset($_SESSION["Email_Address"]))?$_SESSION["Email_Address"]:"")); ?>
Hoping you can point me in the right direction.
