Q:

Codeigniter - multiple input with loop

I wanted to make the multiple inputs with loop and the different value for each data I fill, it seems this code is working but it was only for getting 1 data to 3 data with the same value, what I wanted is that I can make different value for each data in the form.
Or maybe do I need a model for this one or something? been struggle for few days here please help
this is what i expect for the result in the form loop

but what i get is image 2
controller.php
public function aksi_soal3(){
        $ps5 = $this->input->post('soal');
        $ps6 = $this->input->post('opsi_a');
        $ps7 = $this->input->post('opsi_b');
        $ps11 = $this->input->post('kunci_jawaban');

        $data = array(
            array(
                'soal' => $ps5,
                'opsi_a' => $ps6,
                'opsi_b' => $ps7,
                'kunci_jawaban' => $ps11
            ),
            array(
                'soal' => $ps5,
                'opsi_a' => $ps6,
                'opsi_b' => $ps7,
                'kunci_jawaban' => $ps11
            ),
            array(
                'soal' => $ps5,
                'opsi_a' => $ps6,
                'opsi_b' => $ps7,
                'kunci_jawaban' => $ps11
            )
        );

        $this->db->insert_batch('soal',$data);
        redirect('guru/index');

A:

You need to do something like below,
Controller
public function aksi_soal3(){
        $ps5 = $this->input->post('soal');
        $ps6 = $this->input->post('opsi_a');
        $ps7 = $this->input->post('opsi_b');
        $ps11 = $this->input->post('kunci_jawaban');
     $data = array();
    foreach($ps5 as $key=>$value) {
        $data[]  = array(
                'soal' => $value,
                'opsi_a' => $ps6[$key],
                'opsi_b' => $ps7[$key],
                'kunci_jawaban' => $ps11[$key]
            );
    }
        $this->db->insert_batch('soal',$data);
        redirect('guru/index');
    }

View
<input type='hidden' name='kode_soal[]' value='$soal->kode_soal''>
            <textarea placeholder='soal[]' name='soal'></textarea>

            <input type='text' name='opsi_a[]' placeholder='jawaban a'>
            <input type='text' name='opsi_b[]' placeholder='jawaban b'>
            <input type='text' name='kunci_jawaban[]' placeholder='Kunci jawaban' >
