I have some content that has state field. I would like to permit users with the same state to delete this content.
Can I implement this in Drupal?
Can I implement it with PHP code?



PS. Do not include <?php ?> tags.

; $Id:
name = Custom
description = Custom validate node delete permission
package = Custom
core = 6.x


     * file
    function MYMODULE_form_alter(&$form, &$form_state< $form_id){
        case 'node_delete_confirm':
          $form['#validate'][] = 'my_custom_validate';

    function my_custom_validate($form, &$form_state){
      $nid = $form_state['values']['nid'];
      $node = node_load($nid);
      if(/* conditions */) {
        // some procedure to check fields
        $message = t('You have not any permission to delete this node!');
        form_set_error('nid', $message);

Place this files into /sites/all/modules/custom/*.* and activate it on module administration page. Enjoy.

  • It's wrong to add a "version" line in .info files; Drupal core modules use such line, but third-party modules should not use it. – apaderno Apr 10 '11 at 12:20
  • for sure. I'm forget to delete this line – dobeerman Apr 10 '11 at 21:51
