All images getting vanished expect first image, as the form gets some error

I have the same issue!
When uploading more than 65 Images into an Image field (with Multiupload) a notice is being displayed:
Notice: Undefined index: display_field in mfw_field_widget_value() (line 140 of /home/site/public_html/site/sites/all/modules/multiupload_filefield_widget/multiupload_filefield_widget.field.inc).

After this deleting images is not anymore possible and there are no images being displayed in the node.
Is there a patch for it?

For 65 images it works? If so this sounds like a server setting problem to me. Try increasing max_input_vars, max_file_uploads, post_max_size and max_file_uploads.

@czigor I uploaded the images in Packets with 20 images in each of it. After uploading 70 images only 66 images are being displayed in the backend and no images are being displayed in the frontend. I can't even delete an image in the backend. The only possibility to remove the images it to delete the whole node.

Your form might have got too big. Try to increase the php.ini max_input_vars directive.

@czigor Thank you! I've overwritten the max_input_vars directive in the htaccess file.
.htaccess:
php_value max_input_vars 5000

Did it help?

Yes, it worked.
But after 300 images I get this AJAX error message:
Eine AJAX-Anfrage ist abnormal beendet worden.

Is there a way to solve this problem without increasing the max memore size?

Hi seadil, yes you can increase the memory with a php.ini setting:memory_limit
Thake a look to this article: https://www.drupal.org/node/29268

Same issue here.
It occours also if the dimension requirements are not valid for an image.

This is actually a MFW issue.
The steps to reproduce are:

1. Minimal drupal install + MFW + Field UI
2. Create a content type with a file field with unlimited cardinality.
3. Go to the node add form of this content type.
4. Add several files to the file field. Do not fill in the required Title.
5. Submit the node.
6. Validation fails, so fill in the Title. Submit again.

Result: Only the first file appears in the file list.

Hello,

Any updates with a fix for this issue?

Hi,

I have attached the short solution to fix this issue. Please apply the patch.

Hi @all,

I have debuged the issue. We cannot use form_set_error in submission process. I have updated the previous patch.

@asghar: Great catch, seems to work for me!

That patch change only multiupload_imagefield_widget errors but error on any other field (eg node title field) that bug processing

Thank you all! Committed! 🍻
