How can i looping calling every 2 row in my database when clicking next button codeigniter php
Question
I try to make my program called every 2 row every time i click next button. where should i put the increment function?. i use codeigniter
so far i only could manage to make this program which is stopped after i clicked the next button only once
This is my controller
public function form_1(){
$data = array();
$limit_per_page = 2;
$total_records = $this->keur_model->get_total();
if(isset($_POST['next'])){
$this->session->set_userdata('counter', 0);
$start_index = $this->session->userdata('counter') + 2;
// die(var_dump($start_index));
}else{
$start_index = 0;
}
$data["listpertanyaan"] = $this->keur_model->form1($limit_per_page, $start_index);
// $data["links"] = $this->pagination->create_links();
$this->load->view('form2',$data);
}
And This is my model
public function form1($limit_per_page, $start_index){
$this->db->limit($limit_per_page, $start_index);
$query = $this->db->get("tb_pertanyaan");
if ($query->num_rows() > 0)
{
foreach ($query->result() as $row)
{
$data[] = $row;
}
return $data;
}
return false;
}
and this is my html
<body> <form method="POST"> <?php $count = 0; foreach ($listpertanyaan->result_array() as $list) { ?> <label><?php echo $list['desk_pertanyaan'] ?></label> <input type="text"></input><br> <?php $count++; if ($count == 2){ break; } } ?> <input type="submit" name="next" value='Next Question'> </form> </body>
i expect the loop is actually continue based on total rows in the database. the x variable is supposed to be a parameter that know where the next row started because i have a column called no_urut in my database which is a sequential number

Can you use pagination concept, you can fetch the data from the db with limit 2 and the next button will include the limit and offset
$this->db->from('nation');
$this->db->limit($limit, $start);
$query = $this->db->get();
