Delete Message
Tip: Deleting a message involves authorized management, so the permission to delete a message is Only administrators have it, not everyone has the permission to delete, but this chapter shows you how to delete messages, it does not involve permissions
Deleting messages is actually deleting the data in our database
We passed in the id of each message before deleting the link
<td><a href="ressage_delete.php?id=<?php echo $ row['id']?>" >Delete</a> </td>
So receive the id on the PHP page, and then delete the related id, you can delete it The function
code is as follows
<?php
header("content-type:text/html;charset=utf-8");
$conn=mysqli_connect("localhost","root","root","ressage");
$id=$_GET['id'];
if($conn){
$sql="delete from ressage_user where id ='$id' ";
$que=mysqli_query($conn,$sql);
if($que){
echo"<script>alert('刪除成功，返回首頁(yè)');location.href='ressage.php';</script>";
}else{
echo "<script>alert('刪除失敗');location='" . $_SERVER['HTTP_REFERER'] . "'</script>";
exit;
}
}die("數(shù)據(jù)庫(kù)連接失敗" .mysqli_connect_error());
?>
