Я следую этому руководству: https://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/
Я получаю: {"error": true, "error_msg": "Обязательные параметры (имя, адрес электронной почты или пароль) отсутствуют!"} при запуске register.php на POSTMAN с POST, и он выдает ту же ошибку на RAW.
единственная ошибка, которую я получаю, когда я ставлю: http://localhost/android_login_api/register.php на POSTMAN с методом POST: {"error ": true," error_msg ":" Обязательные параметры (имя, адрес электронной почты или пароль) отсутствуют! "}
и при задании значения параметра: http://localhost/android_login_api/register.php?name=arnav&email=arnav.kaushal800@gmail.com&password=password.Я получаю фатальную ошибку: на логическом для метода prepare ().

Даже после передачи всех параметров, я все еще получаю следующую ошибку: {"error": true, "error_msg": "Обязательные параметры (имя, адрес электронной почты или пароль) отсутствуют!"}.
