Resizing images on upload problem

[wayne.davies]

Hi I have an image field in the back end, that expects multiple images. Now I've added this hook as the files are added:

$page->addHookAfter('InputfieldFile::fileAdded', function($event) {
    $inputfield = $event->object;
    wire('log')->save('image-resizing', "Resizing ");
    $image = $event->argumentsByName("pagefile");
    $image->size(800,0,array('upscaling' => false));
    $image->size(300,200,array('cropping' => true, 'quality' => 80 ));
  });

It works absolutely fine for a small amount of images, but uploading a large amount doesn't seem to work. No errors are logged either.

Now all thes photos appear to have uploaded in the back end, and show the thumbnails, but upon clicking save images are missing.

I've checked all my php settings and ensured they are all adequate enough.

memory_limit 512mb
upload_max_filesize 200mb
max_execution_time 300

If I disable this hook, I can upload all images fine.

Please could anyone other any insight into what may be causing this issue?

Thanks in advance

Witch PW version is this on?

Do you use DB-SessionHandler?

Can you view Apache logs? Any entries there?

Sorry forgot to mention that! Its ProcessWire 2.7.2 and yes I use the DB-SessionHandler.

I've checked all the logs, including Apache and nothing appears to show a problem.

If you can, disable the session DB-handler. It is known for this behave in regard with multiple parallel images uploads.
Or, if you cannot switch to session handling via files, the only other alternative is to switch PW Version up to PW 3.0.21+ (?) not sure the correct version where DB-Sessionhandler was updated / corrected.

Other possiblities are not there in your case, I believe.

Sorry, I forgot about it. Another solution would be to stick with PW 2.7 and the (old) SessionHandler-DB, but uploading multiple images packed into a ZIP!

(only one ZIP at a time)

This I uses on a client side with (old) SessionDB-Handler since PW 2.5, (upgraded to 2.6, then to 2.7) for years now, and it works correct!

Thank so much, would have never have figured that out! I've disabled the DB Session handler for now, and is all working fine.
