In my application I am using 2 php files where one contains all the funtions required for the application and the another is to retrive and send the data back to the user
My first php file is DB_Functions.php which contains the following code
<?php
class DB_Functions {
private $conn;
// constructor
function __construct() {
require_once 'DB_Connect.php';
// connecting to database
$db = new Db_Connect();
$this->conn = $db->connect();
}
/**
* Storing new user
* returns user details
*/
public function storeUser($name,$sex,$dob,$email,$college,$password,$latitude,$longitude,$pass) {
$uuid = uniqid('', true);
$hash = $this->hashSSHA($password);
$encrypted_password = $hash["encrypted"]; // encrypted password
$salt = $hash["salt"]; // salt
$stmt = $this->conn->prepare("INSERT INTO CFLASH_USERS(Name, sex, dob, mail, college, password, latitude, longitude, pass, salt, created_at) VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, NOW())");
$stmt->bind_param("ssssssssss", $name, $sex, $dob, $email, $college, $password, $latitude, $longitude, $pass, $salt);
$result = $stmt->execute();
$stmt->close();
// check for successful store
if ($result) {
$stmt = $this->conn->prepare("SELECT * FROM CFLASH_USERS WHERE mail = ?");
$stmt->bind_param("s", $email);
$stmt->execute();
$user = $stmt->get_result()->fetch_assoc();
$stmt->close();
return $user;
} else {
return false;
}
}
/**
* Encrypting password
* @param password
* returns salt and encrypted password
*/
public function hashSSHA($password) {
$salt = sha1(rand());
$salt = substr($salt, 0, 10);
$encrypted = base64_encode(sha1($password . $salt, true) . $salt);
$hash = array("salt" => $salt, "encrypted" => $encrypted);
return $hash;
}
/**
* Decrypting password
* @param salt, password
* returns hash string
*/
public function checkhashSSHA($salt, $password) {
$hash = base64_encode(sha1($password . $salt, true) . $salt);
return $hash;
}
}
?>
My second php file Register.php contains
<?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'];
$sex = $_POST['sex'];
$dob = $_POST['dob'];
$email = $_POST['email'];
$college = $_POST['college'];
$password = $_POST['password'];
$latitude = $_POST['latitude'];
$longitude = $_POST['longitude'];
$pass = $_POST['pass'];
// create a new user
$user = $db->storeUser($name, $sex, $dob, $email, $college ,$password, $latitude, $longitude, $pass);
if ($user) {
// user stored successfully
$response["error"] = FALSE;
$response["uid"] = $user["mail"];
$response["user"]["name"] = $user["Name"];
$response["user"]["sex"] = $user["sex"];
$response["user"]["dob"] = $user["dob"];
$response["user"]["email"] = $user["mail"];
$response["user"]["college"] = $user["college"];
$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);
}
?>
My table structure is 
I am unable to insert the data into it. I have checked for the post meathod to be wrong but it not wrong. So I thought that there will be an error with bind_param(). Please let me know where the error is and a solution to rectify it.
Please explain me about "Call to undefined method mysqli_stmt::get_result()"
