ThinkPHP5.0基础增删改查
首先打开官网参考手册http://www.kancloud.cn/manual/thinkphp5/118003
检查所属环境是否否和，
参考官方文档安装TinkPHP5.0（三种方法）
并查看目录结构
配置一域名直接指向public，即可访问其下面的index.php入口文件
然后看其应用配置文件
配置文件基本不必更改，（若必要可更改访问默认模块）。
看其数据库配置文件
填写必要的东西
接下来创建Model，view等文件
相对于thinkphp3.2来说改变有所大，控制器名不能与模型名必须不同
以下是其简单代码：
Index.php控制器：
<?php
namespace appindexcontroller;
use thinkController;
use thinkRequest;
use appindexmodelGoods;
class Index extends Controller
{
public function index()
{
return view("goods");
}
public function insert()
{
$request = Request::instance();
$data = $request->post();
$goods = new Goods;
$result = $goods->insertData($data);
if ($result) {
$this->success("新增成功", "index/show");
} else {
$this->error("新增失败");
}
}
//展示
public function show()
{
$goods = new Goods;
$arr = $goods->show();
return $this->fetch("show",["arr" => $arr]);
}
//删除
public function delete()
{
$request = Request::instance();
$id = $request->get("id");
$goods = new Goods;
$result = $goods->deleteData($id);
if ($result) {
$this->success("删除成功", "index/show");
} else {
$this->error("删除失败");
}
}
//修改页面
public function update()
{
$request = Request::instance();
$id = $request->get("id");
$goods = new Goods;
$res = $goods->findData($id);
return view("update",["res" =>$res]);
}
//修改数据
public function save()
{
$id = $_POST["u_id"];
$request = Request::instance();
$data = $request->post();
// var_dump($data);die;
$goods = new Goods;
$result = $goods->updateData($data,$id);
if ($result) {
$this->success("修改成功", "index/show");
} else {
$this->error("修改失败");
}
}
}
模型Goods.php:
<?php
namespace appindexmodel;
use thinkDb;
use thinkModel;
class Goods extends Model
{
protected $table = "goods";//表名
//增加
function insertData($data)
{
return Db::table($this->table)->insertGetId($data);
}
//展示
function show()
{
return Db::table($this->table)->select();
}
//删除
function deleteData($id)
{
return Db::table($this->table)->where("u_id","=",$id)->delete();
}
//查询单条
function findData($id)
{
return Db::table($this->table)->where("u_id","=",$id)->find();
}
//修改
function updateData($data,$id)
{
return Db::table($this->table)->where("u_id","=",$id)->update($data);
}
}
基本的表单页面goods.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<center>
<form action="insert" method="post">
<table>
<tr>
<td>用户名</td>
<td><input type="text" name="u_name"></td>
</tr>
<tr>
<td>密码</td>
<td><input type="text" name="u_pwd"></td>
</tr>
<tr>
<td></td>
<td><input type="submit" value="提交"></td>
</tr>
</table>
</form>
</center>
</body>
</html>
展示页面show.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<center>
<table border=1>
<th>ID</th>
<th>用户名</th>
<th>密码</th>
<th>操作</th>
{volist name="arr" id="vo"}
<tr>
<td>{$vo.u_id}</td>
<td>{$vo.u_name}</td>
<td>{$vo.u_pwd}</td>
<td><a href="update?id={$vo.u_id}">修改</a><a href="delete?id={$vo.u_id}">删除</a></td>
</tr>
{/volist}
</table>
</center>
</body>
</html>
修改页面update.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<center>
<form action="save" method="post">
<table>
<tr>
<td></td>
<td><input type="text" name="u_id" value="{$res["u_id"]}"></td>
</tr>
<tr>
<td>用户名</td>
<td><input type="text" name="u_name" value="{$res["u_name"]}"></td>
</tr>
<tr>
<td>密码</td>
<td><input type="text" name="u_pwd" value="{$res["u_pwd"]}"></td>
</tr>
<tr>
<td></td>
<td><input type="submit" value="修改"></td>
</tr>
</table>
</form>
</center>
</body>
</html>
至此简单的增删改查都已完成。
