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

In the latest version of CakePHP $this->response->type() and $this->response->body() are deprecated.

Instead you should use $this->response->withType() and $this->response->withStringBody()

E.g:

(this was pinched from the accepted answer)

if ($this->request->is('post')) {
    $location = $this->Locations->patchEntity($location, $this->request->data);
    if ($this->Locations->save($location)) {
        //$this->Flash->success(__('The location has been saved.'));
        //return $this->redirect(['action' => 'index']);
        $resultJ = json_encode(array('result' => 'success'));

        $this->response = $this->response
            ->withType('application/json') // Here
            ->withStringBody($resultJ)     // and here

        return $this->response;
    }
}
