How to Multiple Delete With CodeIgniter

Next create a database codeigniter_crud , create a student table like the following conditions below sqlnya:
-- -- Database: `codeigniter_crud` -- -- -------------------------------------------------------- -- -- Table structure for table `siswa` -- CREATE TABLE IF NOT EXISTS `siswa` ( `nis` bigint(11) NOT NULL, `nama` varchar(30) NOT NULL, `jurusan` varchar(10) NOT NULL, `alamat` text NOT NULL ) ENGINE=InnoDB AUTO_INCREMENT=998765336 DEFAULT CHARSET=latin1; -- -- Dumping data for table `siswa` -- INSERT INTO `siswa` (`nis`, `nama`, `jurusan`, `alamat`) VALUES (998765122, 'Yusuf Hamdani', 'RPL', 'Jln. Cipaku Haji Rt.02/07 No.15 Kel.Cipaku Kec.Bogor Selatan'), (998765335, 'Rahmayanti', 'Multimedia', 'Jln. Muarasari, Kel.Gunung Batu Kec.Bogor Barat'); -- -- Indexes for dumped tables -- 
Open Controller welcome.php then edit as below:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); class Welcome extends CI_Controller { /** * Index Page for this controller. * * Maps to the following URL * * - or - * * - or - * Since this controller is set as the default controller in * config/routes.php, it's displayed at * * So any other public methods not prefixed with an underscore will * map to /index.php/welcome/<method_name> * @see */ public function index() { $this->load->model('msiswa'); $data['hasilsiswa'] = $this->msiswa->ambildata(); $this->load->view('index', $data); } function delete_multiple() { $this->load->model('msiswa'); $this->msiswa->remove_checked_siswa(); redirect('welcome/index'); } } /* End of file welcome.php */ /* Location: ./application/controllers/welcome.php */ 
Create a new file in the Models folder where msiswa.php :
<?php class Msiswa extends CI_Model { function ambildata() { $ambildata = $this->db->get('siswa'); if ($ambildata->num_rows() > 0) { foreach ($ambildata->result() as $data) { $hasilsiswa[] = $data; } return $hasilsiswa; } } function remove_checked_siswa() { $action = $this->input->post('action'); if ($action == "delete") { $delete = $this->input->post('msg'); for ($i=0; $i < count($delete) ; $i++) { $this->db->where('nis', $delete[$i]); $this->db->delete('siswa'); } } } } ?> 
The snippet of this image describes the coding to display the existing data in the databasecodeigniter_crud student table :
This is for the process when the data will be deleted:
Then create a new file in the Views folder named index.php :
<!DOCTYPE html> <html> <head> <title>AZZURA Media | Membuat Multiple Delete Dengan CodeIgniter</title> <script type="text/javascript" src="<?php echo base_url(''); ?>assets/js/jquery-1.5.2.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("input[name='checkAll']").click(function() { var checked = $(this).attr("checked"); $("#myTable tr td input:checkbox").attr("checked", checked); }); }); </script> </head> <body> <h1>Multiple Delete Dengan CodeIgniter</h1> <form action="<?php echo site_url('welcome/delete_multiple'); ?>" method="post"> <select name="action"> <option value="null">Bulk Action</option> <option value="delete">Delete</option> </select> <input type="submit" name="submit" value="Action"> <p></p> <table border="1" id="myTable"> <thead> <tr> <th><input type="checkbox" id="checkAll" name="checkAll"></th> <th>NIS</th> <th>Nama</th> <th>Jurusan</th> <th>Alamat</th> </tr> </thead> <tbody> <?php if (count($hasilsiswa)>0) { foreach ($hasilsiswa as $data): ?> <tr> <td><input type="checkbox" name="msg[]" value="<?php echo $data->nis; ?>"></td> <td><?php echo $data->nis; ?></td> <td><?php echo $data->nama; ?></td> <td><?php echo $data->jurusan; ?></td> <td><?php echo $data->alamat; ?></td> </tr> <?php endforeach; } else { echo "<tr><td colspan=5>DATA KOSONG!!</td></tr>"; } ?> </tbody> </table> </form> </body> </html> 
Description in the index.php file , you must first download JQuery Docs: Selectors / checked then input jquery script to checkAll below:
<script type="text/javascript"> $(document).ready(function() { $("input[name='checkAll']").click(function() { var checked = $(this).attr("checked"); $("#myTable tr td input:checkbox").attr("checked", checked); }); }); </script>

Named the checkbox id like this, intended to call the javascript function we created, when the checkbox is clicked fed automate all checkAll:
For the post method submitted by the input checkbox we created, we named the checkbox mgs [], to create the array when the data is deleted, following the script snippet:
After completing all the above discussion, you can directly try the program that friend made earlier, if it is correct it will appear as below, so when checkbox next door clicked to eat data will check all, and to delete data Sahabat must choose Select Bulk Action Changed to Delete option then press Action button:
