Cakephp3: How can I return json data?

Question

I am having a ajax post call to a cakePhp Controller:

$.ajax({
                type: \"POST\",
                url: \'locations/add\',
                data: {
           


        

Answer 1

When you return JSON data you need to define the data type and response body information like below:

$cardInformation = json_encode($cardData);
$this->response->type('json');
$this->response->body($cardInformation);
return $this->response;

In you case just change this return json_encode(array('result' => 'success')); line with below code:

$responseResult = json_encode(array('result' => 'success'));
$this->response->type('json');
$this->response->body($responseResult);
return $this->response;
