delete（删除处理页面）
<?php
$code = $_GET["code"];
$db = new MYSQLi("localhost","root","","0710_info");
$sql = "delete from fruit where ids='{$code}'";
if($db->query($sql)){
header("location:del_page.php");
}else{
echo "删除失败!";
}
第三步：实现对数据库中数据的修改功能（与主界面连接）
代码如下 ：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>修改功能</title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>
<link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css"/>
</head>
<style>
*{
margin: 0px auto;
padding: ;
}
.input-group{
margin-top: 15px;
}
.sub{
margin: 20px 260px 10px;
}
</style>
<body>
<div style="height: 100px;"></div>
<?php
$code = $_GET["code"];
$db = new MYSQLi("localhost","root","","0710_info");
$sql = "select * from fruit where ids='{$code}'";
$result = $db->query($sql);
$arr = $result->fetch_row();
?>
<form action="update_processpage.php" method="post">
<div class="panel panel-default" style="max-width: 600px;">
<div class="panel-heading">
修改数据
</div>
<div class="panel-body">
<div class="input-group">
<span class="input-group-addon">代号</span>
