Steps to reproduce:

  1. Create a node type with an image field with minimum dimensions of 300x500 pixels
  2. Create a new node of that type and attempt to upload an image which is smaller than 300x500 pixels
  3. Error message presented: "The specified file test.jpg could not be uploaded. The image is too small; the minimum dimensions are 300x500 pixels."
  4. Attempt to upload an image which is at least 300x500 pixels

Expected results:
Image is successfully uploaded and the error message is removed.

Actual results:
Image is successfully uploaded but the error message from the previous upload is still present.

From what I can tell the problem is in file_ajax_upload() in file.module. The markup generated by theme('status_messages') is prepended to the rendered form and ends up outside the form's ajax-wrapper div. When the form is submitted a second time only the ajax-wrapper div is replaced and the message is not removed.

The simplest way to get the status messages inside the ajax-wrapper is to replace line 238 of file.module:
  $output = theme('status_messages') . drupal_render($form);
  $form['#prefix'] .= theme('status_messages');
  $output = drupal_render($form);

I verified that this change fixes the problem however I'm new enough to Drupal that someone else should look at this. There might be a better way to solve this or an edge case which is broken by this change.

Version:7.15» 8.x-dev

Does this issue exist in 8.x-dev?

lxs’s picture

Yes, I am able to reproduce the same issue with 8.x-dev (September 24, 2012 - 08:19).

It also looks like $output = theme('status_messages') . drupal_render($form); still exists in file_ajax_upload() in Drupal 8 (now on line 951). I checked and my above patch does still fix the problem.

This could be a good starting point for a novice in creating patches and writing tests. It should be backported to D7 once is fixed in 8.x.

Test added, see attached patches.

This bug/fix seems to be applicable to all validations, not just image size. To keep the test simple, it checks file extension validation.

Closed #1020916: File ajax upload doesn't clear previous error message after successful ajax upload as a duplicate (although technically this was the duplicate since it's newer).

Is there a reason the tests aren't being backported to Drupal 7 also?

ndobromirov’s picture

I needed the patch in 7 and I was in a hurry in the middle of a project.
Probably sometime this week(end) I'll attempt to back-port the tests also.

Can confirm that the patch works on live with no side effects for almost 2 months now.

Hi, i believe there is a fix for this issue in Drupal 7 and its not fixed in Drupal 6.23.

Patch correctly fixes the issue for me, but the steps to reproduce need to be slightly tweaked:

1) Choose a file that doesn't pass validation
* Error appears
2) Click the upload button
3) Choose a file that doesn't pass validation again
4) File appears in dialog
5) Click upload
* Error appears
6) Choose a file that does pass validation
7) Click upload
* Error remains

After applying the patch, the error disappears after clicking upload, but it might be better to remove it after you choose a correct file?

lmeurs’s picture

As acbramley says in #22: moving the messages to inside the AJAX wrapper works great, thank you! His remark about error messages being removed right after selecting a file could be easily fixed by wrapping the error messages. The patch would look like:

- $output = theme('status_messages') . drupal_render($form);
$form['#prefix'] .= '<div class="file-upload-js-error">' . theme('status_messages') . '</div>';
$output = drupal_render($form);


There are two types of file validation:

  1. The file extension is validated client side,
  2. The file size is validated server side.

When selecting a file, Drupal.file.validateExtension() is fired which removes possible earlier inserted error messages right away. This only happens to error messages inserted client side by this same function, since these messages have the .file-upload-js-error class. By wrapping the server side messages in a DIV with the same class, they also immediately get removed as soon as a new file is only selected.

But there is a catch...

Situation: After uploading a too large file, a server side error is returned. When now selecting a file with an invalid extension the client side extension validator is not being fired.

This is because the onchange event has not been bound to the file field after the server side validation error. Drupal.behaviors.fileValidateAutoAttach.attach uses selectors to find the file field (child element), but file_managed_file_process() bases these selectors on the managed file element's ID (parent element). This ID gets incremented on each AJAX file upload / removal, but the ID of the file field only gets incremented in case of an invalid upload.

On top of this, the file field's selector is composed by appending "-upload" to the managed file element's ID which results in selectors like "#edit-attachment--5-upload" when the file field's ID at the same time could be "edit-attachment-upload" or "edit-attachment-upload--3" (the incrementation and position of "-upload" differ).


The server side error messages will be removed immediately when a new file is selected, as long as they are being wrapped as suggested and the selector problem is fixed (or use my workaround from #2235977-1: JS file validation is broken (because ajaxPageState is broken?)).
