如何查看用户以前是否发过帖子,如果是,请突出显示他过去的帖子


How to see if a user has posted before, and if so, highlight his past posts?

我有一个简单的学校博客网站,我需要帮助。我需要它,以便如果之前发布过帖子的用户提交帖子,那么他当前和以前发布的帖子将被突出显示。我知道我需要某种方式来检查该用户是否在我的数据库中,但不确定如何去做。提前谢谢你。如果需要,我也可以发布我的 css 或 html 表单。

谢谢

这是我的PHP

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

    echo $_GET['name'];

    echo "You entered an invalid name!'n";
}

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

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

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

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

您需要:

  1. 创建登录名。创建新帖子后,将其记录在数据库中。下次用户发帖时检查记录。如果记录存在,请对样式执行所需的操作

  2. 如果您不想创建登录系统,请对照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。
