PHP development corporate website tutorial: deleting news information

Click delete to jump to the delnews.php file

Let’s take a look at the code of this file:

<?php
    //删除新闻资讯部分代码
    require_once('conn.php');
    $id = $_GET['id'];
    $sql = "delete from news where id='$id'";
    $res = mysql_query($sql);
    if($res){
        echo "<script>alert('删除成功');location.href='news.php';</script>";
    }else{
        echo "<script>alert('删除失败');location.href='news.php';</script>";
    }
?>

Link to the database, get the parameter id brought by the form, and then write the sql statement. Delete

Execute sql statement and delete successfully, jump to the display page so that we can view it on the display page
