PHP连接mysql数据库进行增删改查--修稿数据

php

$id =  $_GET['id'];

$db = new Mysqli("localhost","root","root","student"); $sql = "select * from student.student WHERE Sno = {$id}"; $result = $db->query($sql); $date = $result->fetch_assoc(); //var_dump($date); ?>  "en">  "UTF-8">    
"post" action="editpost.php"> "hidden" name="Sno" placeholder="id" value=""> 姓名："text" name="Sname" placeholder="姓名" value="" >   性别： "radio" name="Ssex" value="1" if ($date['Ssex'] == 1){echo 'checked';}?> id="man">for="man">男 "radio" name="Ssex" value="0" if ($date['Ssex'] == 0){echo 'checked';}?> id="woman">for="woman">女   出生年月: "text" name="Sbirthday" placeholder="出生年月" value="">   班级or组: "text" name="Class" placeholder="班级" value="">    "submit" value="确认修改">   

2、建立一个之前写到的需要作出修改动作的页面（文件名为：editpost.php）

php

$id = $_POST['Sno'];
$name = $_POST['Sname']; $sex = $_POST['Ssex']; $birthday = $_POST['Sbirthday']; $class = $_POST['Class']; $db = new Mysqli("localhost","root","root","student"); $sql = "update student set Sname='{$name}',Ssex='{$sex}',Sbirthday='{$birthday}',Class='{$class}' WHERE Sno='{$id}'"; if ($db->query($sql)){ header("location:crud.php"); }

之后就可以进行测试了！

测试一下：

1、在首页点击修改（选择修改ID：111行）

2、可以成功提取 id 及 信息，就是地址栏的这个信息！

3、对内容进行修改

4、点击确认看一下

5、成功^-^
