PHP syntax

[brettpower]

I want to have a section of my admin interface inform a user if a file does or does not exist.

Basically I want to have the page echo "YES" if the image exists or echo a link to upload the image if it does not exist.

Any ideas?

That is exactly what i need,  however, I can't get the syntax right.

[code]<?php
$filename = ../uploads/xxxxxx.gif';

if (file_exists($filename)) {
  echo "";
} else {
  echo "";
}
?>  [/code]

I have an existing variable ( $row_Upload['campaign'] ) that pulls a campaing ID number that is used on several parts of the page.  The file that I want to verify the existance of is simply the variable with .gif added onto the end.  I can't figure out how to plunk my existing variable into line 1 of the above code with .gif on the end to get the code to work.

Also, if the file does exist, I want a hyperlink to ../uploads/xxxxxx.gif, and if the file is not found, a hyperlink to ../file_upload.php.

If anyone understands what the heck I need, please help.

Thanks.
