Drupal - make the cancel link on the confirm page a button

Question

When I press the delete button on some content, I'm taken to a confirmation page. The delete option is a button, while the cancel option is a link. That looks pretty weird. I found that there's a form_confirm() function in drupal, but I can't understand how to use it. Does anyone know how to make the cancel link into a button?

Answer 1

The reason the cancel link looks like a link, is because it is a link <a>, while the confirm button, is a form submit element <input type="submut>.

If you want to make the cancel link, to look like a submit button, you can do that with pure CSS.

Using hook_form_alter() , try this :

if($form['#theme'] == 'confirm_form') {
    $no = $form['actions']['cancel']['#value'];
    if (!is_null($no)) {
      // Get the text to put on the cancel button
      $value = preg_replace('/(<\/?)(\w+)([^>]*>)/e', '', $no);
      eregi('m|href\s*=\s*\"([^\"]+)\"|ig', $no, $href);

      $form['actions']['cancel']['#value'] = '';

      // Add our own button
      $form['actions']['docancel'] = array(
        '#type' => 'button',
        '#button_type' => 'reset',
        '#name' => 'cancel',
        '#submit' => 'false',
        '#value' => $value,
        '#attributes' => array(
          'onclick' => '$(this).parents("form").attr("allowSubmission", "false");window.location = "'.$href[1].'";',
        ),
      );
      // Prevent the form submission via our button
      $form['#attributes']['onsubmit'] = 'if ($(this).attr("allowSubmission") == "false") return false;';
    }
  }

Or this using no javascript (and replacing eregi() with preg_match()...

  if ( $form['#theme'] == 'confirm_form' ) {
    $no = $form['actions']['cancel']['#value'];
    if (!is_null($no)) {
      // Get the text to put on the cancel button
      $value = preg_replace('/(<\/?)(\w+)([^>]*>)/e', '', $no);
      preg_match('/href\s*=\s*\"([^\"]+)\"/', $no, $href);
      $form['actions']['cancel']['#value'] = '';
      $form['href']=array(
        '#type'=>'value',
        '#value'=>$href[1],
      );

      // Add our own button
      $form['actions']['docancel'] = array(
        '#type' => 'submit',
        '#name' => 'cancel',
        '#submit' => array('mymodule_confirm_form_cancel'),
        '#value' => $value,
      );

    }
  }

and

function mymodule_confirm_form_cancel(&$form,&$form_state) {
  $href=$form['href']['#value'];
  if ( !is_null($href) ) {
    $form['#redirect']=$href;
  }
}
