Question

我有一个简单的学校博客网站，我需要帮助。我需要它，以便如果用户在提交帖子之前已经发布，那么他当前和之前发布的那些帖子将被突出显示。我知道我需要检查一下这个用户是否在我的数据库中，但不知道如何去做。先感谢您。如果需要，我也可以发布我的CSS或html表格。

由于

这是我的PHP

<?php
date_default_timezone_set('EST');
$date_posted = date('h:i:s Y-m-d');
?>

<!DOCTYPE HTML>
<html>
<head>
<link type="text/css" rel="stylesheet" href="post.css" />

<meta name="viewport" content="width=device-width" />
<title>Daily Dorm News</title>
</head>

<body>
<h1>Your Daily Dorm News Post! </h1>
<div id="container"> <?php if ( isset($_GET['name']) and preg_match("/^[A-Za-z0-9]+$/", $_GET['name']) ) {

    echo $_GET['name'];

} else {

    echo "You entered an invalid name!\n";

}

?><br>


Your email address is: <?php if ( isset($_GET['email']) and preg_match("/.+@.+\..+/i", $_GET['email']) ) {

    echo $_GET['email'];

} else {

    echo "You didn't enter a proper email address!\n";

}
?><br>
You Posted : <?php if ( isset($_GET['message']) and preg_match("/^[A-Za-z0-9]+$/", $_GET['message']) ) {

    echo $_GET['message'];

} else {

    echo "The message is not valid! The message box was blank or you entered invalid symbols!\n";

}
?>

This event happened :<?php echo $_GET["date"]; ?><br>

您需要：

创建登录。创建新帖子后，将其记录在数据库中。下次用户发布时检查记录。如果存在记录，请使用样式
如果您不想创建登录系统，请根据电子邮件地址进行检查。这种方法容易出现滥用错误等，

无论哪种方式，您都需要跟踪一些唯一标识符。

如何查看用户之前是否发布过，如果是，则突出显示过去的帖子？
