Non SuperUser can't upload Images: Unexpected token

Recommended Posts

Hi i'm having a recurrent problem I found on this forum: when using the image uploader I get the following error on console "Unexpected token < in JSON". But I couldn't solve it with any of the other proposed solutions:

  • setting debug to true
  • setting $config->uploadTmpDir = dirname(__FILE__) . '/assets/uploads/';
  • setting uploadTmpDir in php.ini

 

BUT This problem only appears for non superuser users (ie editors).

Running on a Digitial Ocean Server with NGINX and PHP 7.1. Version is ProcessWire 3.0.62

Note: Im using Fredi plugin, but i doubt that's the problem because I'm using it in other sites with no problem

 

Any idea how i could solve this (even with non ajax image upload) I need to sort this as fast and simple as possible :)

Thanks in advance

It looks like there is a PHP error message breaking the JSON - you need to go into your dev console and click on the image upload ajax call and go to the response tab.

Thanks @adrian

You made me realize I had code executing on ready.php which was embedding css in the admin page, hence the unexpected <

Others postings led me to think it was a system problem, rather than my own code.

      I am writing here instead of the ProCache forum because I have the impression that several nginx experts could solve this. In its new version, Procache proposes new .htaccess rules that are difficult to translate into nginx rules. We currently have a problem with the trailing slash of URLs which gives us a bad score in SEO analysis tools such as semrush.com. 
      Indeed, a canonical URL is either without or with "/", but cannot be served by both options. Although ProcessWire without ProCache respects this rule, ProCache has no difficulty serving both, which is considered an SEO optimisation fault. I believe that ProCache version 2 solves this problem with these new rules, but I can't understand the following. Does anyone have any idea how to translate this into a nginx rule?
      Attached also the whole proposed .htaccess for ProcessWire.

      I have a new server and wanted to use nginx. However, I have two ProcessWire websites which does not let me do anything. I'll get this error every time when I try to change something and sometimes when logging in. Deleted all caches already from ProcessWire and browser. This also happens after installing new ProcessWire and all directories were owned by www-data.
      I also have two working websites without any problems and all these four uses same kind of setting on nginx config. I don't understand why some of those working fine and some not.

      Hell,
      Although I use a config on an other of my sites that works well. An error 500 is driving me nuts.

      Hi,
       
      I'm trying to upload images from a folder into a page. I need to replace the images instead of adding. The image field already has the replace existing images turned on, but it doesn't seem to be enough.
       
      My code:
      foreach($files as $file) { if(substr($file, 0, 1) != '.' && $file != '.' && $file != '..') { // Get SKU $file_sku = substr($file, 0, 9); // Check for book $book = $pages->get('sku=' . $file_sku); if(!$book->id) { // Book doesn't exist } else { // Upload image into book !!! THIS CODE ADDS FILE INSTEAD OF REPLACING. HOW CAN I REPLACE? $book->book_images->add($upload_directory . '/' . $file); // Delete file unlink($upload_directory . '/' . $file); } // Save book if($book->id) $book->save(); } }  
      What am I missing?

      I'm trying to implement a front-end image upload form for user profile pictures, to a field called 'profile_picture'. The code is based on the various examples found around these forums but isn't yet 100% right.
      The form successfully submits the image to the server and updates the field in the dashboard. When you submit the firm, the page reloads and uploads the image but the template still loads the old image path (now broken path as the old image has been removed).
      I can only get the new image to show if I hit enter in the address bar forcing the page to reload.
      Any ideas? Is it a caching issue, or something to do with the order of the script? It makes no difference if I call the image after the upload form.
      <?php //Display current user image $userImg = $user->profile_picture->first(); echo '<img src="'.$userImg->url.'">'; $upload_path = $config->paths->assets . "files/avatar_uploads/"; $f = new WireUpload('userimage'); $f->setMaxFiles(1); $f->setMaxFileSize(1*1024*1024); $f->setOverwrite(true); $f->setDestinationPath($upload_path); $f->setValidExtensions(array('jpg', 'jpeg', 'png', 'gif')); if($input->post->form_submit) { if(!is_dir($upload_path)) { if(!wireMkdir($upload_path)) throw new WireException("No upload path!"); } $files = $f->execute(); if ($f->getErrors()) { foreach($files as $filename) @unlink($upload_path . $filename); foreach($f->getErrors() as $e) echo $e; } else { $user->of(false); $user->profile_picture->removeAll(); // wirearray (line added by @horst: explanation is three posts beneath) $user->profile_picture = $upload_path . $files[0]; $user->save(); $user->of(true); @unlink($upload_path . $files[0]); } } ?> <form class="forum-form" accept-charset="utf-8" action="./" method="post" enctype="multipart/form-data" > <input type="file" id="attach" name="userimage" accept="image/jpg,image/jpeg,image/gif,image/png" /> <input type="submit" name="form_submit" value="Submit"/> </form>
