how i get checked checkbox

    <?php $j=1; foreach ($dudu as $row2 ): ?>

    <td><input type="checkbox" name="popok[]"
  <?php if(strrpos($row->menu_allowed,''.$j.'')!==FALSE){echo 'checked';$j++;}/></td>

    <?php endforeach; ?>

if the data 1,2,3,4 it will check

1    2   3   4
[v] [v] [v] [v]

but if the data not sequential like 1,3,4 it only check the first box

1    3  4
[v] [] []

Answer 1

in your controller get the chek box value

<?php
class Test extends CI_Controller {

    function index()
    {

        $check_status = $this->test_model->get_checkbox_status();
        $data['check_status'] = $check_status;

        $this->load->view('testview', $data);
    }
}
?>

then in your view

<td><input <?php if($check_status==1){"checked='checked'";}?> type="checkbox" name="cb"  /></td>

UPDATE

use strrpos

<?php if(strrpos($check_status,'1')!==false){"checked='checked'";}?>

this will check 1

another method using a for loop

<?php  for($i=1;$<6;$i++) { >?

<td><input <?php if(strrpos($check_status,$i)!==false){"checked='checked'";}?> type="checkbox" name="cb"  /></td>

<?php } ?>
