title: Skip validation on node delete in Drupal 7
body: <p>How can I accomplish skipping validation when the user attempts to delete a node in Drupal 7?
  I am calling my custom validation function in the following manner:</p>
  
  <pre><code>function my_issue_form_alter(&amp;$form, &amp;$form_state, $form_id) {
      switch ($form_id) {
          case 'my_issue_node_form':{
              $form['#validate'][] = 'my_issue_node_form_validate';
              break;
          }
      }
  }
  
  function my_issue_node_form_validate($form, &amp;$form_state) {
      //custom validation done here
  }
  </code></pre>
  
  <p>I've been looking around for a couple days now and most of the possible solutions are considering the developer is creating a custom form, which I am not.</p>
  
  <p>Thanks in advance for any tips/advice.</p>
