foreach $FILES create post how to

    I know this is probably super easy and I am overlooking something here.

    I have a form on the front-end of our website where users can upload an image via a form and it creates a product in our shop. We are using WordPress and Woocommerce but I felt this question was general enough to ask on here.

    Currently everything works fine when uploading one image, How would I make this work for when a user uploads multiple images?

    In the form I changed
    <input type="file" name="thumbnail" id="thumbnail" />
    to
    <input type="file" name="thumbnail" id="thumbnail" multiple />and I thought wrapping the below in something like this would work:

    if ($_FILES) {
      foreach ($_FILES as $file => $array) {
        // do necessary code
      }
    }

    But it doesn’t.

    Here is what I have that creates the post. Im not sure why wrapping it in the foreach $FILES won’t work?

    You can view the paste bin here: https://pastebin.com/VvwBAEG5

    In short I just need a way for the above code to create the post for each file uploaded, instead of just one file uploaded like it currently does.. Im all out of ideas

    Got it, so I changed the name of the file input from thumbnail to thumbnail[]. Then I wrapped the above paste in a function and added this part at the top of the file and it works perfectly:

    if ( $_FILES ) {
    	$files = $_FILES['thumbnail'];
    		foreach ($files['name'] as $key => $value) {
    		  if ($files['name'][$key]) {
    		  $file = array(
    		  'name' => $files['name'][$key],
    		  'type' => $files['type'][$key],
    		  'tmp_name' => $files['tmp_name'][$key],
    		  'error' => $files['error'][$key],
    		  'size' => $files['size'][$key]
    		  );

    			  $_FILES = array("" => $file);

    			  foreach ($_FILES as $file => $array) {
    			          //call my function
    				  create_var_product($file, $post_id);
    			  }
    		  }
    	}
    }
