I am trying to make an android login system and when I try to register I am getting that the user failed to store and I am not able to find the error. I am using 000webhost I don't know if it has something to do with that. Please help and thank you
I have the Internet permission, and the login is working so I think is not a problem of the connection or the database. When I try to register, the code goes to the "user failed to store" section, printing out "Unknown error occurred in registration!".
This is the register.php:
<?php
require_once 'include/DB_Functions.php';
$db = new DB_Functions();
// json response array
$response = array("error" => FALSE);
if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['password'])) {
// receiving the post params
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];
// check if user is already existed with the same email
if ($db->isUserExisted($email)) {
// user already existed
$response["error"] = TRUE;
$response["error_msg"] = "User already existed with " . $email;
echo json_encode($response);
} else {
// create a new user
$user = $db->storeUser($name, $email, $password);
if ($user) {
// user stored successfully
$response["error"] = FALSE;
$response["uid"] = $user["unique_id"];
$response["user"]["name"] = $user["name"];
$response["user"]["email"] = $user["email"];
$response["user"]["created_at"] = $user["created_at"];
$response["user"]["updated_at"] = $user["updated_at"];
echo json_encode($response);
} else {
// user failed to store
$response["error"] = TRUE;
$response["error_msg"] = "Unknown error occurred in registration!";
echo json_encode($response);
}
}
} else {
$response["error"] = TRUE;
$response["error_msg"] = "Required parameters (name, email or password) is missing!";
echo json_encode($response);
}
?>
And this is the DB_Functions.php class:
<?php
class DB_Functions {
private $conn;
// constructor
function __construct() {
require_once 'DB_Connect.php';
// connecting to database
$db = new Db_Connect();
$this->conn = $db->connect();
}
// destructor
function __destruct() {
}

$RESULT = array();
for ( $i = 0; $i < $stmt->num_rows; $i++ ) {
$Metadata = $stmt->result_metadata();
$PARAMS = array();
while ( $Field = $Metadata->fetch_field() ) {
$PARAMS[] = &$RESULT[ $i ][ $Field->name ];
}
call_user_func_array( array( $stmt, 'bind_result' ), $PARAMS );
$stmt->fetch();
}
return $RESULT;
}
