I have a form which has a checkboxes field.

This field has an ajax callback attached

$form['checkboxes'] = array(
  '#type' => 'checkboxes',
  '#title' => 'test',
  '#ajax' => array(
    'callback' => 'mymodule_ajax_callback',
    'wrapper' => 'test-wrapper',
    'method' => 'replace'

function mymodule_ajax_callback(&form, &$form_state) {
  return $form['another-field'];

When I check a checkbox, the ajax callback is executed. Then when I try to submit the form through form submit button, it reloads the same page with values in the fields, but the form is not submitted.

I have tried $form_state['rebuild'] = TRUE in the ajax callback also but it did not help.

I have added the #name and #id properties also to the submit button but no luck.

Is there any other solution which I can try?

  • Could you please post the code for the submit button? – user72672 Aug 28 '19 at 7:06
  • The submit function is not calling – Ahmad Aug 28 '19 at 7:22
  • @Jdrupal When I submit the form without checking a checkbox in that field, the form gets submitted successfully and the submit function calls – Ahmad Aug 28 '19 at 7:23
  • Event the validation does not work after ajax callback executed. – Ahmad Aug 28 '19 at 7:25

I think the problem is that you only return the another-field in the ajax callback.

You probably have to make a wrapper for the submit and the another-field.

So you willl have:

$form['ajax_wrapper'] = array(
  'submit' => array(
    // Submit button...
  'another-field' => array(
    // Another field...

And then return $form['ajax_wrapper'] in your ajax callback. Make sure to use $form_state['rebuild'] = TRUE;

  • This will work by I think this is not the problem. Because it is already working for one language and for other languages it is not working. – Ahmad Aug 28 '19 at 8:39
  • What do you mean by language? – user72672 Aug 28 '19 at 8:40
  • When you return only one field in your ajax callback, then the submit button "is not a part of the form" anymore, if you understand what I mean? You have to return all elements that you want to be in the form after you have checked the checkboxes. – user72672 Aug 28 '19 at 8:42
