Question

我已经定义了storedUsername和storedPassword，但仍然面临错误说明

注意：未定义的变量：第13行的C：\ xampp \ htdocs \ mongosample \ index.php中的storedUsername

<?php
include './connect.php';
if(($_SERVER["REQUEST_METHOD"]=="POST") && (!empty($_POST['username'])) && (!empty($_POST['password']))){
$postedUsername = $_POST['username'];
$postedPassword = $_POST['password'];
    $userDatabaseFind = $database->Bcard->find(array('username' => $postedUsername, 'password' => $postedPassword));

    foreach ($userDatabaseFind as $useFind){
        $storedUsername = $useFind['username'];
        $storedPassword = $useFind['password'];
    }

    if(($postedUsername == $storedUsername) && ($postedPassword == $storedPassword)){
        header('location:welcome.php');
    }
    else{
        echo 'Error';
    }
}   ?>

我知道，密码不应该以空白文本传递，所以请不要提及

您应该在foreach循环之前初始化变量

$storedUsername = '';
$storedPassword = '';

然后是你的foreach循环

虽然变量已定义但是出现错误
