Multiple Checkbox Input in CodeIgniter

Posted on

Sometimes we need to insert multiple checkbox value to our database. We also need to combine our input values with our ID to get some table relations. For example, we will auto cluster students to class A and B. So, we need to have an input form there show students username, and optional value for class A or B.

If we press the submit button, it will process and save id_siswa and class to our new table. This table just for new relations. You know, if there is mandatori relations, so we need new table for save the relations.

Here is my simple code,

The controller

<?php defined('BASEPATH') OR exit('No direct script access allowed'); class Welcome extends CI_Controller { public function index() { $this->load->view('welcome_message');

	public function proses_kelas(){

	$id_siswa = $this->input->post('id_siswa');
	$kelas = $this->input->post('kelas[]');	

	$jml_siswa = count($id_siswa);
	for ($i=0;$i<$jml_siswa;$i++){ $data = array('id_siswa' => $id_siswa[$i], 'kelas' => $kelas[$i] );
	echo "sukses";

The view

<!DOCTYPE html>
	<title>Multiple checkbox</title>

<form action="http://localhost:8080/multiplecheckbox/index.php/welcome/proses_kelas" method="post">
<table border="1">
$ambil_siswa = $this->db->get('siswa')->result();
foreach ($ambil_siswa as $key) {


			<input type="hidden" name="id_siswa[]" value="<?=$key->id?>">
				<input type="checkbox" name="kelas[]" value="A"> A
				<input type="checkbox" name="kelas[]" value="B"> B
<?php } ?>
<button type="submit">Proses</button>

I didn’t model file, because in this case, I pull student data from view. Its just for example case study, you can implement this code to your case.
