CodeIgniter-Access from model to controller - php

Question

I have the following code in Model:
<?php
class Route_Model extends CI_Model
{
function __construct()
{
parent::__construct();
}
public function getRoute($date = array())
{
try {
$data = array(
'route' => array(
'id' => 1,
'name' => 'budapest-athens',
'price' => 150,
'id' => 2,
'name' => 'rome-madrid',
'pret' => 250,
'id' => 3,
'name' => 'belgrade-bucharest',
'price' => 180,
'id' => 4
)
);
return $data;
} catch (Exception $e) {
return $e->getMessage();
}
}
}?>
And I want to access array elements in my controller.
How can I access each field separately?
Something like $price = $this->data['price']?
Thank you!

Answer 1

You are returning an array with two levels, if you want to get the price from the array $data, simply do this in your controller:
$data = $this->route_model->getRoute($date);
$price = $data['route']['price'];
Please, note that your array is not well formed because you have repeated keys and this may cause problems

Answer 2

This array will never work since you're overwriting keys, I think you would want the following array:
$data = [
'route' => [
[
'id' => 1,
'name' => 'budapest-athens',
'price' => 150
], [
'id' => 2,
'name' => 'rome-madrid',
'price' => 250
], [
'id' => 3,
'name' => 'belgrade-bucharest',
'price' => 180
]
]
];
Next to that, your try / catch seems unnecessary here, there is no real try. It's a hard-coded array, so unless this will actually do some interactions there is no need for the try / catch.
Anyway, to receive this data in your controller you should do:
$this->load->model('Route_model');
$route = $this->Route_model->getRoute();
var_dump($route);
exit;
Now you will have this array. Another wonder, are you actually trying to grab all the routes in this array, or is there something you want to do with the $date parameter? Since right now it doesn't looks like it's used unless you stripped some code away.
