I have a problem after inserting some data from array, the insert data works properly. But the Redirect doesn't work, I don't understand the error, because no error message show just the blank page, I have tried and tried until it become habit that makes me tired.
Here is the Function Controller that I use:
public function all() {
    $data       = array();
    $idkelas    = $this->input->post('kelas');
    $idabsen    = $this->input->post('idabsensi');
    $idabsen2   = $this->input->post('idabsen');
    $id         = $this->input->post('idsiswa');
    $hadir  = $this->input->post('hadir');
    $smt        = $this->input->post('semester');
    $jamke  = $this->input->post('jamke');
    $count      = count($id);
    // to absensi
    $this->db->query("UPDATE absensi SET jmlhadir = '$count' WHERE idabsensi = '$idabsen2'");
    // to absensidetail
    for($j=0; $j < (int)($count); $j++) {
        $data[] = array(
            'idabsensi'     => $idabsen[$j],
            'idsiswa'       => $id[$j],
            'statusabsen'   => $hadir[$j],
            'semester'      => $smt[$j],
            'jamke'         => $jamke[$j]
            );
        }
        return $this->db->insert_batch('absensidetail', $data);
        redirect('absensi/absen/pilihkelas/'.$idkelas, 'refresh');
}
This is the View:
<form action="<?php echo base_url()?>absensi/absen/all" method="post">
<input type="submit" class="btn btn-info btn-large" value="ABSENT ALL" />
<table class="table table-striped table-bordered table-condensed">
            <thead>
                <tr>
                    <th>No.</th>
                    <th>No. Induk</th>
                    <th>Student Name</th>
                    <th>Gender</th>
                    <th>State</th>
                    <th></th>
                </tr>
            </thead>
            <tbody>
            <?php $i=0 ?>
            <?php foreach($kel as $d):
            $i++;
            ?>
            <tr class="list-users">
                <td><input type="hidden" name="idsiswa[]" value="<?=$d->idsiswa?>" readonly><?=$d->idsiswa?></td>

                <td>
                    <div class="btn-group">
                        <a class="btn btn-mini dropdown-toggle" data-toggle="dropdown" href="#">Actions <span class="caret"></span></a>
                        <ul class="dropdown-menu">
                            <li><a ><i class="icon-pencil"></i>Press Button<BR>ABSENT ALL First</a></li>
                        </ul>
                    </div>
                </td></tr>
            <?php endforeach ?>
            </tbody>
        </table>
     </form>
I really hope someone can help me. Thank You
