Ajax производит неправильный вывод в Javascript

Я не могу понять, почему мой аякс выводит неправильный код. Его вывод нагрузок css, я считаю, что это из моего файла MySQLDao.php, но я не уверен. Код ниже. Кто-то сказал, что это потому, что строка «data: {action: 'getResults'} игнорируется, но я не уверен, как это сделать, поэтому она не игнорируется. Любая помощь приветствуется. Спасибо!

Часть моего кода JavaScript:

function callPHP() { $.ajax ({ type: "GET", datatype: "application/json", url: "MySQLDao.php", data: { action : 'getResults' }, success: function(output) { alert(output); } }); } callPHP(); 

Мой PHP-файл:

 <?php require("Conn.php"); header("Access-Control-Allow-Origin: *"); error_reporting(E_ALL); ini_set('display_errors', 1); //Class for holding queries class MySQLDao { private $dbhost = null; private $dbuser = null; private $dbpass = null; private $mysqli = null; private $dbname = null; private $result = null; //constructor function __construct() { $this->dbhost = Conn::$dbhost; $this->dbuser = Conn::$dbuser; $this->dbpass = Conn::$dbpass; $this->dbname = Conn::$dbname; } //Attempt a connection to the database public function openConnection() { //Try and connect to the database $this->mysqli = new mysqli($this->dbhost, $this->dbuser, $this->dbpass, $this->dbname); //If the connection threw an error, report it if (mysqli_connect_errno()) { return false; } else { return true; } } //Get method for retrieving the database conection public function getConnection() { return $this->mysqli; } //Close the connection to the database public function closeConnection() { //If there is a connection to the database then close it if ($this->mysqli != null) $this->mysqli->close(); } //-----------------------------------QUERY METHODS------------------------------------- public function generateRoomID() { $sql = "INSERT INTO room (room_id) VALUES (null);"; $result = $this->mysqli->query($sql); if ($result == true) { $toReturn["status"] = true; $toReturn["roomID"] = $this->mysqli->insert_id; return $toReturn; } else { $toReturn["status"] = false; $toReturn["message"] = mysql_error($this->mysqli); return $toReturn; } } public function saveRoom($data) { $roomID = $data[0]; $roomDescription = $data[1]; $columns = $data[2]; $rows = $data[3]; $this->mysqli->autocommit(FALSE); $this->mysqli->query("UPDATE room SET room_description='".$roomDescription."'

Мой класс подключения:

 <?php class Conn { public static $dbhost = "xxx"; public static $dbname = "xxx"; public static $dbuser = "xxx"; public static $dbpass = "xxx"; } ?> 

Мой базовый класс:

 <?php require("Conn.php"); require("MySQLDao.php"); $handle = fopen("php://input", "rb"); $raw_post_data = ''; while (!feof($handle)) { $raw_post_data .= fread($handle, 8192); } fclose($handle); if (empty($raw_post_data)) { $returnValue["status"] = false; $returnValue["title"] = "Error"; $returnValue["message"] = "No Data Recieved"; echo json_encode($returnValue); return; } else { $dao = new MySQLDao(); if ($dao->openConnection() == false) { $returnValue["status"] = false; $returnValue["title"] = "Error"; $returnValue["message"] = "Connection Could Not Be Established Between Server And Database"; echo json_encode($returnValue); } else { //Decodes data, dont change $body = json_decode($raw_post_data, true); $recieved = $body["data"]; //Gets the result of a query //$result = $dao->MySQLDaoMethodName(parameters); //Return the result of the query echo json_encode($result); } $dao->closeConnection(); return; } ?>
