I want to create an API in Codeigniter which will get the cart_list and cart_list will have latitude, longitude of a store, I want to check the distance between post parameters(latitude, longitude) and return the distance.
Now, I am trying to create a controller in controllers folder of Codeigniter and written a function to get the cart_list but I am unable to get the list, I just tried to return 'success' as in response to this api but I am getting response as
{
"status": false,
"error": "Unknown method."
}
distance_calculator
<?php
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
require APPPATH.'/libraries/api/REST_Controller.php';
class distance_calculator extends REST_Controller
{
function distance_calculator()
{
parent::__construct();
$this->load->model('mdl_cart_web');
}
function cart_list($offset = 0)
{
$limit = '';
$data = array();
$s_data = $_POST;
$carts = $this->mdl_cart_web->get_cart_list($limit,$offset,$s_data)->result_array();
$totalRows = $this->mdl_cart_web->get_total_cart_product($s_data)->num_rows();
// $data = $this->mdl_common->pagination_data('cart/get_cart_list/',$totalRows,$limit,'show_data');
$data['carts'] = $carts;
$data['total_cart'] = $totalRows;
$this->response('success', 200);
}
}
?>
I also declared route in routes file
routes
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
$route['default_controller'] = "home1";
$route['cart_list'] = 'distance_controller/cart_list';
I am calling this function as
http://test.pricewhirl.com/index.php/distance_calculator/cart_list
with GET method,and in response I get error unknown method.
I am a beginner in web development. Please help with this, thank you.
always add method name as post fix in code. like if you wrote a function with post method use -> cart_list_post() and if you wrote a function with get method use -> cart_list_get()
You must define the type of request in the method name :
function cart_list_get() {
....
}
From doc :
When your controller extends from REST_Controller, the method names will be appended with the HTTP method used to access the request. If you're making an HTTP GET call to /books, for instance, it would call a Books#index_get() method.
If you are using Rest Controller you have to use Postfix _post for POST method and _get for GET method in function like
public function abc_post()
I know this isn't an answer, but if you need documentation check out this article on how to make an api out of CI
