PHP IF/ELSE

[davecheet]

I have six thumbnails on a page and a large image. On clicking the thumbnail the thumbnail reloads the page with a URL variable 'photo' which then becomes the enlarged image source. All of that works perfectly at the moment.

However, the first time the page is loaded the URL variable 'photo' is not present so I'm trying to use IF/ELSE to automatically make it show 'photo 1' if URL variable 'photo' is not present.

Unfortunately I just can't make it work. The image source returns blank when no URL variable is present instead of defaulting to $row_rs_properties['photo1']

Can anyone suggest why this code doesn't work?

$photo = isset($_GET['photo'])?$_GET['photo']:'photo1';
$photo=($row_rs_properties[$photo]);

Make sure that this comes AFTER the recordset.

Thanks Murray,

I pasted in your code after the recordset (and deleted my own) but still a blank result for the main image source. But now a blank return even when the URL variable is present.

Let's see the whole thing, please.

You were right though. I just reinstated my code but moved it to after the recordset and now it works like a swiss watch.

Problem Solved.

Excellent. I was scratching my head for explanations if that had not been
the case! 8)
