PHP開發 學生管理系統之添加資訊PHP頁面
接收從add.php頁面傳過來的數據，將數據保存到資料庫中
提示：本教程是將添加，修改，刪除，的PHP程式碼放在同一個PHP頁面，我們用了switch，case語句，下面的程式碼是不完整的action.php 檔案程式碼，等我們將添加，修改，刪除的功能完成，會將完整的程式碼展示給大家
先連結我們的資料庫
header("content-type:text/html;charset=utf8");
$conn=mysqli_connect("localhost","root","root","study");
mysqli_set_charset($conn,"utf8");
$conn=mysqli_connect("localhost","root","root","study");
mysqli_set_charset($conn,"utf8");
接收我們從新增頁面傳來的訊息
$name = $_POST['name'];
$sex = $_POST['sex'];
$age = $_POST['age'] ;
$class = $_POST['class'];
$sex = $_POST['sex'];
$age = $_POST['age'] ;
$class = $_POST['class'];
$sql = "insert into stu (` name`, sex, age, class) values ('$name', '$sex','$age','$class')";
$rw = mysqli_query($conn,$sql);##$rw = mysqli_query($conn,$sql);
新增資訊代碼如下
<?php
header("content-type:text/html;charset=utf8");
$conn=mysqli_connect("localhost","root","root","study");
mysqli_set_charset($conn,"utf8");
if($conn){
switch ($_GET['action']){
case 'add'://add
$name = $_POST['name'];
$sex = $_POST['sex'];
$age = $_POST['age'];
$class = $_POST['class'];
$sql = "insert into stu (`name`, sex, age, class) values ('$name', '$sex','$age','$class')";
$rw = mysqli_query($conn,$sql);
if ($rw > 0){
echo "<script>alert('添加成功');</script>";
}else{
echo "<script>alert('添加失败');</script>";
}
}
}
header('Location: index.php');
break;
?>下一步就是將我們新增的資訊展示出來
