Hello,

I want to use AJAX to submit a form & replace some content while the code runs in the background. I've made a form that works but if I ad the AJAX callback it no longer actions the form.

This may be really obvious but I can't seem to get it working, is there a trick to it?

Here is a simplified version of what I'm trying to do. Any feedback is appreciated.

function trial_registration_form($form, &$form_state) {

  $form = array();
  $form['#method'] = 'post';
  $form['#action'] = url(register.php');
  $form['#suffix'] = '<div id="form-register-message"></div>';

  $form['name'] = array(
      '#title' => t('Name'),
      '#type' => 'textfield',
      '#required' => TRUE,
    );
    // submit
    $form['submit'] = array(
      '#type' => 'submit',
      '#value' => t('Submit'),
      '#ajax' => array(
        'callback' => 'trial_registration_form_submit',
        'wrapper' => 'form-register-message'
      ),
      '#submit' => array('trial_registration_form_submit'),
    );
    return $form;
 }

function trial_registration_form_submit($form, &$form_state) {

  // create message
  $content = t('Thank you for registering. An email with login details will be sent to you shortly.');

  // Process form submission.
  $commands = array(
    ajax_command_replace('#form-register-wrapper', $content),
  );

  $replace = array('#type' => 'ajax', '#commands' => $commands);

  return $replace;
}

Try this:

function trial_registration_form_submit($form, &$form_state) {
   $element = $form;
   if(!form_get_errors()) {
       $element = t('Thanks for registering. We will contact you soon');
   }
   return $element;
}

This works for the ajax submit. This will replace the form with our custom message.

Changing the #action of the link will cause the ajax to fail. Why are you changing the action? You should almost never have to do this in Drupal.
