I am trying to write an auto increment in a custom module that will check how many records exist for a specific content type (responses) and then add to a custom field the count + 1.

Response 1, Response 2, etc…

Ultimately I want to count how many entities of the type responses exist that are also related to a parent entity that is referenced when I save the form, but at this stage I can’t even get it to count and populate my custom field on save.

I’ve hunted around and ended up with the following code (Im learning in Drupal 8)… can anyone see what I am doing wrong please. My work flow is just to create a new entity called responses and press save.

Thanks in advance for any assistance

// Add a custom submit handler function myschool_hook_node_responses_form_alter(&$  form, &$  form_state) { //Add a custom submit handler  $  form['#submit'][] = 'myschool_custom_submit'; }  // Custom submit handler to assign the custom field value myschool_custom_submit(&$  form, &$  form_state) {   $  form_state['values']['field_response_number']['und'][0]['value'] = myschool_preprint_increment();  }  // Custom function to increment by one function myschool_preprint_increment() { // Content type machine name $  type = "responses";   $  nodes = node_load_multiple(array(), array('type' => $  type));   // STILL TO DO – Add a check for reference ID = Parent Entity ID and count from that   if (!empty($  nodes)) {     $  pre_print_number = "Response";     $  pre_print_number .= count($  nodes) + 1;   }   else {     $  pre_print_number = "Response1"; //First response if empty    }    return $  pre_print_number;
