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
//删除练习我们信息部分代码
require_once('conn.php');
$id = $_GET['id'];
$sql = "delete from contact where id='$id'";
$res = mysql_query($sql);
if($res){
echo "<script>alert('删除成功');location.href='contact.php';</script>";
}else{
echo "<script>alert('删除失败');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.
