error when call JSON response - mylastof - 09-10-2020 Hello, I don't know this is bug or not. But ... I have Controller A with method like : Code: public function myjson() { when call : http://localhost:8080/a/myjson showing the output, JSON but the problem is, when call by other controller show Error like "Call to a member function setContentType() on null" ... ____ when code changed to Code: public function myjson() { no error RE: error when call JSON response - T.O.M. - 09-10-2020 If you want to return JSON from your controller method you should set JSON to response and return it - https://codeigniter.com/user_guide/outgoing/response.html?highlight=setjson#setting-the-output PHP Code: return $this->response->setJSON($json); Besides, variable $json may be an array (or maybe, it should be) - it is converted automatically to JSON. RE: error when call JSON response - davodm - 01-31-2021 I have the same problem on ResponseTrait.php at line 398. The problem is about calling setContentType in Response Class. So I suggest defining $this->response first in the "respond()" function. PHP Code: public function respond($data = null, int $status = null, string $message = '') RE: error when call JSON response - hasanbasri93 - 12-18-2022 (01-31-2021, 01:35 AM)davodm Wrote: I have the same problem on ResponseTrait.php at line 398.
