I have a content type on which I added a custom validation that there can't be more than 7 items of that content type that is marked as 'sticky'. That validation was added on the add and edit pages through omhm_mod_form_blog_node_form_alter(&$form, &$form_state, $form_id)
with the line $form['#validate'][] = 'omhm_mod_form_nouvelle_node_form_validate';
and my custom validation omhm_mod_form_nouvelle_node_form_validate
.
Now I have to make a page with views bulk operations with the same custom validation in place ... how can I do that ?
I'm trying to add the custom vbo validation views_bulk_operations_form_validate($form, &$form_state)
to my omhm_mod_views_bulk_operations_form_alter($form, &$form_state, $form_id)
hook with the line $form['select']['submit']['#validate'][] = 'omhm_mod_carrousel_views_bulk_operations_form_validate';
but nothing happens.
