File Upload (works locally, but not on remote server)

Question

I'm trying to upload a file (msword/doc) to a Apache server folder via an HTML form. It works when I test it locally (I'm testing it via MAMP), but when I upload it to a remote server (such as GoDaddy), it doesn't work. It shows "There was a problem with the file upload".

Below is the snippet of code that processes the file upload. I can't figure out what is wrong with my conditional.

      // Move the file to the target upload folder
      $target = FILE_UPLOADPATH . basename($new_file);
      if (move_uploaded_file($_FILES['new_file']['tmp_name'], $target)) 
      {
        // The new file move was successful, now make sure any old file is deleted
        if (!empty($old_file) && ($old_file != $new_file)) 
        {
          @unlink(FILE_UPLOADPATH . $old_file);
        }
      }
      else 
      {
        // The new file move failed, so delete the temporary file and set the error flag
        @unlink($_FILES['new_file']['tmp_name']);
        echo 'There was a problem with the file upload.' . PHP_EOL;
      }

Can you share the full $_FILES array, as the value in the error param may help shed some light on this — fullybaked, Apr 29 '13 at 16:05
Here is the $_FILES array output: Array ( [new_file] => Array ( [name] => sample.doc [type] => msword/doc [tmp_name] => /tmp/phpsTu20P [error] => 0 [size] => 119674 )) Thoughts? — kthaker, Apr 29 '13 at 16:25
Comment out your @unlink call for now to ensure that the only thing tested is your upload, and post results. Does the newly uploaded file still not appear in the directory — fullybaked, Apr 29 '13 at 16:29
@kthaker What does `var_dump(is_writable($target));` give you? — popthestack, Apr 29 '13 at 16:36
The issue was with permissions. I didn't realize the server I was testing on had ACLs set up. So my chmod permissions changes didn't go through. Thanks for the advice :) — kthaker, Apr 29 '13 at 16:49

If $_FILES['new_file']['error'] == 0 then the upload isn't the problem, but the call to move_uploaded_file() is. You probably have incorrect permissions on the directory you're trying to move the file to.

Are you sure that the folder you are uploading to has permission for files to be written to it? If not, use chmod 0777 and test with that.

Yes it has chmod 775 permissions. – kthaker Apr 29 '13 at 16:25

Does your destination folder have proper permissions? http://en.wikipedia.org/wiki/Chmod The directory write to typically needs 775: What are the proper permissions for an upload folder with PHP/Apache?

Also, do you want users to have direct access to the file? If not you should consider writing the file to a folder that is above your web root directory.

I double checked the permissions. They are 775. And yes, I do wants users to have direct access to the file. I think the problem may be in the 'move_uploaded_file' line. The database stores the filename in the table and shows it on the form after the upload. But when I check the upload folder, the file is not present. – kthaker Apr 29 '13 at 16:27

For me, I happened to be testing locally with a file under php's upload_max_filesize while testing remotely with a file over upload_max_filesize. See https://stackoverflow.com/a/30359278/3325776 for more info.
