PHP development corporate website tutorial: Delete contact us information
We have already completed the function of adding and modifying, now let’s write the function of deleting
Click delete, then pass the parameter id, receive the parameter id on this page and perform the deletion operation based on the id
The code is as follows:
<?php
//刪除練習(xí)我們信息部分代碼
require_once('conn.php');
$id = $_GET['id'];
$sql = "delete from contact where id='$id'";
$res = mysql_query($sql);
if($res){
echo "<script>alert('刪除成功');location.href='contact.php';</script>";
}else{
echo "<script>alert('刪除失敗');location.href='contact.php';</script>";
}
?> determines the executed sql statement. If the deletion is successful, it will jump to the display page. If it fails, it will also jump to the display page.
