首先，建立一个主页面（crud.php）
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<?php
$db = new Mysqli("localhost","root","root","student");
!empty(mysqli_connect_error())?die("连接错"):"";
$sql = "select * from student";
$data = $db->query($sql)->fetch_all();
//var_dump($data);
<table border="1">
<tr>
<td>ID</td>
<td>姓名</td>
<td>性别</td>
<td>出生年月</td>
<td>班级</td>
<td>删除</td>
<td>修改</td>
</tr>
<?php
foreach ($data as $i){
if ($i[2] == 1){
$i[2] = "男";
}
else if ($i[2] == 0){
$i[2] = "女";
}
else{
$i[2] = "保密";
}
echo "<tr><td>{$i[0]}</td><td>{$i[1]}</td><td>{$i[2]}</td><td>{$i[3]}</td><td>{$i[4]}</td><td><a href='dele.php?id={$i[0]}'> 删除 </a></td><td><a href='edit.php'> 修改 </a></td><tr>";
}
?>
<!-- 2-->
</table>
<a href="add.php">新增用户</a>
</body>
</html>
一、增加
1、建立add.php ，插入表单
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<form method="post" action="addpost.php">
<input type="text" name="Sno" placeholder="id">
<input type="text" name="Sname" placeholder="姓名">
<input type="radio" name="Ssex" value="1" id="man"><label for="man">男</label>
<input type="radio" name="Ssex" value="0" id="woman"><label for="woman">女</label>
<input type="text" name="Sbirthday" placeholder="出生年月">
<input type="text" name="Class" placeholder="班级">
<input type="submit" value="提交">
</form>
</body>
</html>
2、在addpost.php里做数据库增加处理
<?php
$id = $_POST['Sno'];
$name = $_POST['Sname'];
$sex = $_POST['Ssex'];
$birthday = $_POST['Sbirthday'];
$class = $_POST['Class'];
$db = new Mysqli("localhost","root","root","student");
$sql = "insert into student.student VALUES ('{$id}','{$name}','{$sex}','{$birthday}','{$class}',0)";
//var_dump($db->query($sql));
if ($db->query($sql)){
header("location:crud.php");
}else{
header("location:add.php");
}
测试一下：
1、主页
2、点击 增加用户 增加内容
3、点击 提交 ，看一下
4、完成 ^-^
