 <?php

include('connect.php');


    if (isset($_POST['username']) && isset($_POST['password'])){

        $username = $_POST['username'];

        $email = $_POST['email'];

        $password = $_POST['password'];

        global $mysqli;

        $query = ("INSERT INTO lr (username, password, email) VALUES ('$username', '$password', '$email')");

        $result = $mysqli->query($query, $connection) or die(mysql_erorr());

        if($result === true){

            $msg = "User Created Successfully.";

这是我的代码,当我点击注册按钮时,我给了我这个错误

  

“致命错误:在第112行的C:\ wamp \ www \ Unnamed Site 2 \ Signup.php中的非对象上调用成员函数query()”

我仍然是这个PHP STUFF的新手需要帮助!

ASLO当我尝试连接我的DATBASE THRU DREAMWEAVER时给我一个错误的说法,那就是没有任何数据显示

感谢提前

答案 0 :(得分:2)

调用成员函数query()意味着您正在尝试使用名为query的函数,该函数不作为php或用户定义的函数存在。

你的变量$ query不应该有()。这用于调用函数。

只使用$ query =“你的SQL查询”;

$query = "INSERT INTO lr (username, password, email) VALUES ('$username', '$password', '$email')";

您不应该依赖用户输入。在使用$ _POST变量之前,你已经在制作$ _POST变量的新变量,这很好,但你应该准备好将它们发送到数据库中。
