I have a multistep webform with required fields. The problem is that when I press the "previous"button in order to go to the page before the validation triggers and does not allow me to change the page. How can I disable the validation if the "previous" button is pressed?

I followed this question but it didnt work by adding this code:

if(isset($form['actions']['wizard_prev'])){
  $form['actions']['wizard_prev']['#validate'] = ['::noValidate'];
}

  • Where did you write that code?

  • @Jdrupal in hook_form_alter. I also use the drupal.org/project/clientside_validation module

    You could try $form['actions']['wizard_prev']['#limit_validation_errors'] = []; instead.

  • If the validation is set with JS, you can't remove it by PHP.
