You're *assigning* a variable in this condition.

How do I specify it that I just want to check to see if the form field was
blank and if so, inform the user?  I know I could do this with JavaScript
but I need to be able to do correct conditions.

thanks

try that

if (!isset($_POST[imgList]) || empty($_POST[imgList])){

for the comparison.

if ( !isset($_POST[imgList]) ) { }

or if imgList is a text string, you could safely punt with:

if ( $_POST[imgList] ==  ) { }

I know I could do this with JavaScript
 but I need to be able to do correct conditions.

What do you mean by correct?  Why can't you do this in JS?  (Note that
even if you do it in JavaScript, you should *still* do it in PHP, to
support all browsers.  These days, quite a few corporate networks force
web traffic through proxies that block JavaScript, cookies and sometimes
even Flash.)
