PHP development news release system news deletion page
Create new_del.php file
We have passed the id of each piece of data in the form of get on the news list page
<a href="new_del.php?id=<?php echo $row['id']?>">Delete</a>
When we modify the page, we only need to receive this id, and then delete the data in the database
The code is as follows
<?php
header("content-type:text/html;charset=utf-8");
$id=$_GET['id'];
$conn=mysqli_connect("localhost","root","root","News");
if($conn){
$sql="delete from new where id ='$id' ";
$que=mysqli_query($conn,$sql);
if($que){
echo"<script>alert('删除成功，返回首页');location.href='new_list.php';</script>";
}else{
echo "<script>alert('删除失败');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
exit;
}
}die("数据库连接失败" .mysqli_connect_error());
?>This will delete our The function is completed
Combining the previous chapters, we have completed the simplest news release system
<?php
header("content-type:text/html;charset=utf-8");
$conn=mysqli_connect("localhost","root","root","News");
$id=$_GET['id'];
if($conn){
$sql="delete from new where id ='$id' ";
$que=mysqli_query($conn,$sql);
if($que){
echo"<script>alert('删除成功，返回首页');location.href='new_list.php';</script>";
}else{
echo "<script>alert('删除失败');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
exit;
}
}die("数据库连接失败" .mysqli_connect_error());
?>
