I have a directory where users can upload an image, this is given their username.

When used, it is checked to see if it exists:

$img = "<img src='"._SEP.$site_data['dir_path'].$file_dir.$uname.".gif' alt='VOID'>";
if (!file_exists($file_dir.$uname.".gif"))
{
$img = "No Image";
}

However, if there is no username then an image is shown anyway, there is no image name '.gif' in the folder, even though it shows another image from somewhere else. Is this a peculiarity of 'file_exists()' (maybe using stat), or what.

 

If before all of this I put:

if(strcmp($uname, "")==0)	{	$uname = "VOID";	}

then it works as expected...

 

This just seems to be an extra unwanted step!

 

 

Sorry about this post, sort of solved it as it was written...

Should you be checking to see if $site_data['dir_path'].$file_dir.$uname.".gif" exists, not just $file_dir.$uname.".gif" ??

 

Depending on where you're at in your directory structure, that'd be your problem.

No, because i'm using mod_rewrite with includes etc, and the actual src path needs to be different. But either way they still wouldn't exist...

this should work better in this instance:

$img = "No Image";
if(isset($uname))
{
$img = "<img src='"._SEP.$site_data['dir_path'].$file_dir.$uname.".gif' alt='VOID'>";
}
