How to send JSON response instead of php redirect?

Question

PHP

Hello, the situation is as follows, after submitting the forms, there is a redirect script

$this->response->redirect($this->url->link('information/contact/success'));

How can I send him a json code, so that instead of a redirect, I would run a script to open a popup. Thanks

Answer 1

json code so that instead of a redirect, I would run a script

JSON is an object , not a code , it is needed to transfer data , and a front-end script can already perform some actions based on this data .
You didn't specify what framework is used on the server, but since it's there $response->redirect(), it $response->json()'s probably also.

Answer 2

Or, as Aleksey Ukolov said , or at the beginning of the action, indicate in the header that Json will be returned and simply return an array.
