Question

我知道这类问题在某些地方得到了回答，但我无法找到并解决我的问题。我使用MySQLi进行登录，它在localhost上正常工作但在服务器上出现错误（致命错误：在非对象/ * PATH * /第14行上调用成员函数query（））。我的Localhost版本是（php：5.5.12和apache 2.4.9），服务器版本是（php 5.3.27）。

这是我的PHP代码

    <?php 
    include 'includes/loginheader.php';
    if (isset($_REQUEST['email']))
    {

        $username = $_REQUEST['email'];
        $password = $_REQUEST['password'];
        //$username = mysqli_real_escape_string($mysqli, $username);
        //$query = mysqli_query($con,"SELECT * FROM user");
        //$result = mysqli_query($query);


        $sql = "SELECT * FROM admin";
        $result = $con->query($sql);

        if(mysqli_num_rows($result) == 0) // User not found. So, redirect to login_form again.
        {
            ?>
            <script>
                $( document ).ready(function() {
                    $("#diverrorpanel").removeClass('hide');
                    $("#diverrormsg").text('Username/ Email Not Found');
                });
            </script>
            <?php
        }
        $userData = mysqli_fetch_array($result, MYSQLi_ASSOC);
        $hash = hash('sha256', $userData['salt'] . hash('sha256', $password) );
        if($hash != $userData['password']) // Incorrect password. So, redirect to login_form again.
        {
            ?>
            <script>
                $( document ).ready(function() {
                    $("#diverrorpanel").removeClass('hide');
                    $("#diverrormsg").text('Invalid Password');
                });
            </script>
            <?php
        }else{ // Redirect to home page after successful login.
            ob_start();
            session_start();
            $_SESSION['email'] = $username;

            header('Location: dashboard.php');
            //echo "Success";
        }

    }
?>
