＆＃13; 这是删除的代码我有两个表1_user_info（有登录的用户）2_posts用户将发布它的帖子有user_id外键我想删除添加此帖的用户的帖子，我希望帮助我请求

<?php
if($_SERVER['REQUEST_METHOD']=='POST'){

include 'connecttomysql.php';

 $con = mysqli_connect($dbserver,$dbusername,$dbpassword,$dbname);

 $ID = $_POST['user_id'];

$Sql_Query = "DELETE FROM posts WHERE user_id = '$ID'";

 if(mysqli_query($con,$Sql_Query))
{
 echo 'Record Deleted Successfully';
}
else
{
 echo 'Something went wrong';
 }
 }
 mysqli_close($con);
?>

Answer 1

试试这个解决方案:) 您可以编辑posts表并为每个帖子添加新行包含id 并且查询将是

$Sql_Query = "DELETE FROM posts WHERE user_id = '$ID' and post_id='$posts_ID'";

现在你只能删除想要的帖子。

如何从添加此帖子的用户中删除帖子中的行？
