I have a problem using #limit_validation_errors for a submit button on which I dont want all the validations to run. Here's my custom submit button :

$form['actions']['draft'] = array(
     '#type' => 'submit',
     '#value' => 'Save as draft',
     '#submit' => array(''),
     '#limit_validation_errors' => array(
       array('title'), // Validate $form_state['values']['title'].

It works perfectly in the sense that it checks the validation on the title field only, but the weird thing is, it does not submit any other field's values when submitted. I wrote a custom submit handler to check that. However, the values are present in $form_state['input'] but not in $form_state['values'].

What I want simply is, this form will submit with just the values given and overlook the validations when this custom submit button is clicked.

FYI : I can get $form_state['values'] perfectly in my custom validate function.

Any ideas? What am I doing wrong here?

It works as expected - in $form_state['values'] you have validated values, and in $form_state['input'] you have raw values. If you will limit validation to title field only - only this field will be transferred into "values" array.


I had to switch from a type="submit" to type="button" in order to disable errors + use ajax.

  public function buildForm(array $form, FormStateInterface $form_state) {

    // ...

    // Create Draft Button
    $form['#prefix'] = '<div id="send-emails-manual-send-by-role-wrapper">';
    $form['#suffix'] = '</div>';
    $form['actions']['save_draft'] = [
      '#type' => 'button',
      '#value' => $this->t('Save Draft'),
      '#name' => 'submit__save_draft', // TODO: Make constant
      '#limit_validation_errors' => [],
      '#ajax' => [
        'callback' => [$this, 'ajaxSubmitForm'],
        'wrapper' => 'send-emails-manual-send-by-role-wrapper',
        'method' => 'replace',
        'effect' => 'fade',
    return $form;  

   * Submit the form using ajax
  public function ajaxSubmitForm(array &$form, FormStateInterface $form_state) {
    $this->submitForm($form, $form_state);
    return $form;
