致命错误:调用未定义的方法mysqli_stmt :: query() [英] Fatal error: Call to undefined method mysqli_stmt::query()

问题描述

嘿，你们中的任何一个都能找出我为什么遇到上述错误的原因吗?

Hey guys, can any of you find out why I'm getting the above error?

$mysqli=new mysqli("localhost", "***", "***","***") or die($mysqli->connect_error);


              function checklogin($username, $password){
                global $mysqli;


                $result = $mysqli->prepare("SELECT * FROM users WHERE username = ?");
                $result->bind_param("s", $username);
                $result->query();

推荐答案

调用$mysqli->prepare()将返回MySQLi_STMT的实例，但是MySQLi_STMT类没有query()方法.也许您是说 execute() ?

Calling $mysqli->prepare() will return an instance of MySQLi_STMT, but the MySQLi_STMT class doesn't have a query() method. Perhaps you meant execute()?
