You forgot to add $ sign
DbOperations.php
<?php
class DbOperations{
private $con;
function __construct(){
require_once dirname(__FILE__).'/DbConnect.php';
$db = new DbConnect();
$this->con = $db->connect();
}
/*CRUD -> c -> CREATE */
public function createUser($name, $surname, $username, $user_pass, $address, $pin, $mail, $phone){
if($this->isUserExist($username,$mail,$phone)){ //<--------change this
return 0;
}else{
$password = md5($user_pass);
$stmt = $this->con->prepare("INSERT INTO `user_data` (`name`, `surname`, `username`, `password`, `address`, `pin`, `mail`, `phone`) VALUES (?, ?, ?, ?, ?, ?, ?, ?);");
$stmt->bind_Param("ssssssss",$name,$surname,$username,$password,$address,$pin,$mail,$phone);
if($stmt->execute()){
return 1;
}else{
return 2;
}
}
}
private function isUserExist($username, $mail, $phone){
$stmt = $this->con->prepare("SELECT id FROM user_data WHERE username = ? or mail = ? or phone = ?");
$stmt->bind_param("sss", $username, $mail, $phone);
$stmt->execute();
$stmt->->store_result();
return $stmt->num_rows > 0;
}
}
