Question
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?
Solution
custom.info
PS. Do not include <?php ?> tags.
; $Id:
name = Custom
description = Custom validate node delete permission
package = Custom
core = 6.x
custom.module
<?php
/*
* file
*/
function MYMODULE_form_alter(&$form, &$form_state< $form_id){
switch($form_id){
case 'node_delete_confirm':
$form['#validate'][] = 'my_custom_validate';
break;
}
}
function my_custom_validate($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.
