嘿，伙计们，我是php的初学者，我正在学习cookie，我现在正在学习教程，但我在调试这个假设存储名称和位置cookie的练习时遇到了问题。
这是我的php脚本
<?php
/**
* In this example, you create a script that can store the visitor’s first name and location in two browser cookies,
* retrieve and display the information from the cookies, and delete the cookies on request.
**/
define('URL', 'https://collabbro-bvcxtds.c9.io/app/php-practice/remember-me.php');
if (isset($_POST['sendInfo'])) {
storeInfo();
} elseif (isset($_GET['action']) and $_GET['action'] == 'forget'){
forgetInfo();
} else {
displayPage();
}
function storeInfo() {
if (isset($_POST['firstName'])) {
setcookie('firstName', $_POST['firstName'], time() + 60 * 60 * 24 * 365, '', '', false, true);
}
if (isset($_POST['location'])) {
setcookie('location', $_POST['location'], time() + 60 * 60 * 24 * 365, '', '', false, true);
}
header('Location:' . URL);
}
function forgetInfo() {
setcookie( 'firstName', '', time() - 3600, '', '', false, true);
setcookie( 'location', '', time() - 3600, '', '', false, true);
header('Location:' . URL);
}
function displayPage() {
$firstName = (isset($_COOKIE['firstName'])) ? $_COOKIE['firstName'] : '';
$location = (isset($_COOKIE['location'])) ? $_COOKIE['location'] : '';
}
?>
这是我的html
<!DOCTYPE html>
<html>
<head>
<title>Remeber me user information with cookies</title>
</head>
<body class="homepage">
<!-- nav -->
<!-- end nav -->
<h1>Remember User infomration with cookies</h1>
<?php if ($firstName or $location) { ?>
<?php echo '<pre>'; var_dump($firstName); exit(); ?>
<?php echo '<pre>'; var_dump($location); exit(); ?>
<p>Hey, <?php echo $firstName ? $firstName : 'visitor' ?> <?php echo $location ? 'in $location' : '' ?>! </p>
<p>Here's a little nursery rhyme I know:</p>
<p><em>Hey diddle diddle, <br>
The cat played the fiddle <br>
the cow jumped over the moon <br>
the little dog laughed to see such sport <br>
and the dish ran away with the spoon </em></p>
<p><a href="<?php URL ?>?action=forget">Forget about me</a></p>
<?php } else { ?>
<form action="<?php URL ?>" method="post">
<input type="text" name="firstName" id="firstName" placeholder="please enter your first name"/>
<input type="text" name="location" id="location" placeholder="Where do you live?"/>
<input type="submit" value="Submit" name="sendInfo" id="sendInfo"/>
</form>
<?php } ?>
<!-- footer -->
<!-- end footer -->
</body>
</html>
以下是我的调试步骤
我做的第一件事是vardump（）$firstName&$location在我的条件声明中<?php if ($firstName or $location) { ?>
这给了我什么，所以我检查我的张贴方法，看看它是否发送回页面（据我所知）
但是看着我处理输入的代码，一切看起来都很好，不知道发生了什么，谢谢你的帮助！
我觉得你的代码不错。尝试将forgetInfo（）中的-3600设置为-3600*24。时间函数在您的服务器中执行，cookie存储在您的计算机中（因此cookie时间在您的电脑中进行评估）。这可能是许多小时的时差。
