[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;
}
} 


I have solved my issue found out why for some reason when I submitted my form if I had error via callback the redirect was clearing it, so therefor no errors were showing up I had to call the main function with the view in it i.e $this->index();

PHP Code:

<?php

class User_group_list extends Admin_Controller {

    public function index() {
        $data['title'] = ucwords(str_replace('_', ' ', $this->router->fetch_class()));

        $data['breadcrumbs'] = array();

        $data['breadcrumbs'][] = array(
            'text' => 'Home',
            'href' => site_url('admin/dashboard')
        );

        $data['breadcrumbs'][] = array(
            'text' =>  ucwords(str_replace('_', ' ', $this->router->fetch_class())),
            'href' => base_url('admin/user_group')
        );

        $data['user_groups'] = array();

        $results = $this->get_user_groups();

        foreach ($results as $result) {
            $data['user_groups'][] = array(
                'user_group_id' => $result['user_group_id'],
                'name' => $result['name'],
                'edit' => site_url('admin/user_group/update' .'/'.$result['user_group_id'])
            );
        }

        if (isset($_POST['selected'])) {
            $data['selected'] = (array)$_POST['selected'];
        } else {
            $data['selected'] = array();
        }

        $this->load->view('template/user_group/user_group_list', $data);
    }

    public function get_user_groups() {
        $user_group = $this->db->get($this->db->dbprefix . 'user_group');
        if ($user_group->num_rows()) {
            return $user_group->result_array();
        } else {
            return false;
        }
    }

    public function delete() {
        $this->load->library('form_validation');

        $selected_post = $this->input->post('selected');

        $this->form_validation->set_rules('selected[]', 'selected', 'required|callback_validateDelete');

        if ($this->form_validation->run($this) == FALSE) {
            $this->index();
        } else {
            $this->session->set_flashdata('success', 'Success: You have modified user groups!');
            redirect('admin/user_group');
        }
    }

    public function delete_user_group($user_group_id) {
        $this->db->where('user_group_id', $user_group_id);
        $this->db->delete($this->db->dbprefix . 'user_group');
    }

    public function validateDelete() {
        $this->load->library('user');
        $this->load->library('form_validation');

        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!
