[Solved] Form Validation Callback With Array "selected[]"

I have a post array called selected on my form name="selected[]";  The set message does not work.


I am still unsure on how to use callbacks with array. I trying to understand it.

My callback message works fine with single post but not array[]


How can I make call back pick up name="selected[]"; and display message.

PHP Code:

public function delete() {
$this->form_validation->set_rules('selected[]', '', 'callback_validateDelete');

if ($this->form_validation->run($this) == FALSE) {

redirect('admin/user_group');

} else {

foreach ($_POST['selected'] as $user_group_id) {
$this->delete_user_group($user_group_id);
}

$this->session->set_flashdata('success', 'Success: You have modified user groups!');
redirect('admin/user_group');
}
}

public function validateDelete() {

$this->load->library('user');

if ($this->user->hasPermission('modify', "User_group_list")) {
return true;
} else {
$this->form_validation->set_message('validateDelete', 'Warning: You do not have permission to modify user groups');
return false;
}
} 


There's only one rule - please don't tell anyone to go and read the manual.  Sometimes the manual just SUCKS!
