Question

我一直在登录页面，我的代码没有工作，有没有人对我应该做什么有任何提示或想法。当我回显num_rows时，它显示0，而不是数据库中实际的行数。

        $Email = mysqli_real_escape_string($dbc, trim($_POST['Email']));
        $Password = mysqli_real_escape_string($dbc, trim($_POST['Password']));


        //Look up the email and password in the database
        $query = "SELECT * FROM Users WHERE Email = '$Email' AND Password = MD5('$Password')";
        $data = mysqli_query($dbc, $query);
        $count = mysqli_num_rows($data);
        echo "Num of Rows: " . $count . "<br/>";

Answer 1

将密码声明和查询更改为此。它会解决问题

$ Password = md5（$ _ POST [＆＃39;密码＆＃39;]）;

$ query =＆＃34; SELECT * FROM Users WHERE Email =＆＃39; $ Email＆＃39; AND密码=＆＃39; $密码＆＃39;＆＃34;;

PHP登录代码无法正常工作任何建议？
