Hi I am looking for the process of regeneration of csrf token in codeigniter when ever a form is submitted using ajax. I want the token to be regenerated without page refres

Answer 1

if it's not on session then you controller will be like this

public function save_date() // or whatever function you like
{
 $regen_token = $this->security->get_csrf_hash();
 $data = array(
      "data" => $this->input->post('datas'),
 );
 $insert = $this->w_m->save($data);
 echo json_encode(array("regen_token" => $regen_token));
}

in your ajax will be look like this:

$.ajax({
 url: "your url",
 type: "POST",
 data: { your data },
 dataType: "JSON",
 success: function(data)
 {
  $("name or id of your csrf").val(JSON.stringify(data.regen_token)).trigger("change"); // this will be the function that every post you'll request and it automatically change the value of your csrf without refreshing the page.
 },
 error: function(errorThrown)
 {
   console.log(errorThrown);
 }
});
