Help with a bug or error

Beginners - Learning PHP
#1

Hi everyone, I need some help, go figure. I have a php photo upload tool that someone built for me a while back but it doesn’t seem to work and nothing I do seams to fix it.

Everytime I try to load the image it gives me the following error:

“Error! Problem [6] reading full size image”

I have included the php file below I use to load the image. I don’t know if I maybe have something setup on the server wrong or what. It used to work on our old server, but never tried it till now on our new server.

PHP file Below:
THANKS

Ok, maybe I am getting somewhere… I understand the “6” in the error I think I believe the PHP file below is telling me that there is a resizing isssue with the images I am trying to load.

SO if my assumption is correct, can someone tell me how you change aceptable sizes???

Here is the other php file I think controling and returning the error:

function BuildCategories(&$categories)
{
$numCat = 0;
$query = "SELECT * FROM `Categories`";
//echo "query = $query<br>n";
if ($res = mysql_query($query)) {
while ($cat = mysql_fetch_array($res)) {
extract($cat);
$categories[$catName] = $catId;
$numCat++;
}
}
return $numCat;
}

function OptArray($a, $sel)
{
reset($a);
while (list ($key, $val) = each ($a)) {
echo "<option value='$val'";
if ($sel && ($sel == $val)) echo " selected";
echo ">$key</option>n";
}
}

Not enough information about the problem and Too much code.

Try and narrow things down a bit to let us know where to start. No one wants to just chug through your large chunk of code.

What have you done to trouble shoot it? What were the results?

The more you narrow things down, the more likely you are to get meaningful help.

#4

My guess is that this line (in the second file you posted):

$mog="/usr/bin/X11/mogrify -format " . $fmt;

is the one causing you trouble since you say you moved servers. From what I can tell this script uses an external program to resize the images and that may not be on the new server or you may not have access. Try looking in to that.
