I have a variable in a link <a href= blah.php?city=LA> Los Angeles </a>
on next page the variable $state is set to = 'city'
this works fine until the varible "city" is empty
I need a way to NOT reset $state if city is empty


<?php if($city !== '' && $city !== 'N/A'){$state=$_GET['city'];} else {$state=$state;} ?>

with this once 'city' is empty it vives $state the value as $_GET[$city]
any ideas? there must be a way

If 'city' is not set, what is the default value for $state then?

PHP Code:

if (empty($_GET['city']) || $_GET['city'] == 'N/A') {
     // city unavailable in URL
     $state = ??
} else {
     // city available
     $state = $_GET['city'];
}

$state is set to nothing until the link is used then it is set to $state=$city
my problem is that on the next link clicked i loose both variables as they become empty

It seems to me that you have the links duplicated on each page and each link goes to a different page.
So if you picked a link that has no value then $state and $city become empty.

Or maybe you have this setup on one page only and each link displays different content.
And when a link has no value then the values in $state and $city are lost.

But I could guess all night on how your program is set up.

Either way, to solve your problem, using sessions would work very well.
