Re: [PHP] Can you use null?
Hi, Just do a test on the result of the image URL field, and if the field value is null (or ), change the field to a default image URL... ? if($myrow[image_url] == or $myrow[image_url] == null) { $myrow[image_url] = images/default_image.gif; } echo IMG SRC=\.$myrow[image_url].\; ?
