How to query table based on value from POST method in CodeIgniter - php

Question

I am fairly new to codeigniter.
I have the following code in my views/check_availability/index.php file:
<?php $type = $_POST['type']; ?>
Create Reservation
<?php foreach ($check_availability as $check_availability_item): ?>
<h2><?php echo $check_availability_item['room_type'] ?></h2>
<div id="main">
<?php echo $check_availability_item['room_description'] ?>
</div>
<p>View article</p>
<?php endforeach ?>
This is my code under models/check_availabiliy_model.php file
public function check_availability($type = FALSE)
{
if ($type === FALSE)
{
$query = $this->db->get('lf_rooms');
return $query->result_array();
}
$query = $this->db->get_where('lf_rooms', array('type' => $type));
return $query->row_array();
}
This is the code in my controllers/check_availability.php file
public function index()
{
$data['check_availability'] = $this->check_availability_model->check_availability();
$data['title'] = 'Available Roooms';
$this->load->view('templates/header', $data);
$this->load->view('check_availability/index', $data);
$this->load->view('templates/footer');
}
Under views/check_availability/index.php file I want to filter the room_type field when I call the check_availability function based on the value from POST method like $type = $_POST['type'].
Currently this is the code that I used to query all the record from lf_rooms table:
<?php foreach ($check_availability as $check_availability_item): ?>
but how can I pass the value of $type variable to check_availability function?

Answer 1

You should get the POST parameter in the controller, query the database accordingly and only display the results in the view. The view should not hold any logic.
public function index()
{
$type = $this->input->post('type', TRUE);
$data['check_availability'] = $this->check_availability_model->
check_availability($type);
}
