在CodeIgniter中使用$ _POST值

Question

Application makes an AJAX request to a method in a controller.

The controller then calls a method in the model to run a query on the DB and then return the results.

AJAX "type" specified as POST.

Even though $_POST superglobal values are available for use in model, should one still list the $_POST values in the model method signature?

I'm thinking this is best practice so people dissecting a system can quickly see inputs going into model methods

$this->Students_table_model->attendance_history_get($_POST['students_id'],$_POST['start_date'],$_POST['end_date']);

public function attendance_history_get($students_id,$start,$end)

VS

$this->Students_table_model->attendance_history_get();

and then just using the available $_POST values in model method attendance_history_get()

Answer 1

I think you should use the codeigniter custom function $this->input->post(); to get the post value

$student_id = $this->input->post('students_id');
$start_date = $this->input->post('start_date');
$end_date = $this->input->post('end_date');
