Laravel框架简单的用户管理[CURD]操作

一个基于laravel和bootstrap的简单的用户管理,适合刚入门的我们,在做的过程中可以加深自己对laravel基础理解,里面存在一些问题,还未修改,比如css和js的引入,表单提交地址等不规范(我是这样认为的,如果你只追求功能那就没任何问题)

多看文档,多做,文档有些点虽然没说,但他娘的的确写在里面了~

larvael 5.5 文档

目录结构

 

  1.样式放在public文件夹下

  2.模板文件以.blade.php为后缀,放在resource/views目录下

  3.路由文件位于routes目录下web.php

  4.表单文件需要在表单中加  {{ csrf_field() }}

遇到的坑

  1.表单提交时,提交地址填写问题,自己注意下点击后跳转地址是否和路由一致

  2.表单提交时,_token都传过去了,值没传过去,奶奶个腿,原来input没给名字,日狗了,写bootstrap时在id上写了name名....尴尬(┬_┬)

常用操作

  创建控制器

  php artisan make:controller UsersController

  使用 PHP 内置的开发环境服务器为应用提供服务,在浏览器中通过 http://localhost:8000 即可访问应用,要一直开着

  php artisan serve

1.模板文件

   

  index.blade.php

2.路由文件

  web.php

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/ Route::get('/',function(){
return '首页';
});
//用户
Route::get('/user', 'UsersController@index');
Route::get('/user/add', 'UsersController@add');
Route::post('/user/doAdd', 'UsersController@doAdd');
Route::get('/user/edit/{id}', 'UsersController@edit');
Route::post('/edit/save', 'UsersController@save');
Route::get('/user/del/{id}', 'UsersController@del');

3.控制器

  UsersController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
class UsersController extends Controller
{
/**
* 遍历用户
*/
public function index()
{
$list = DB::table('user')->select('id','name', 'age')->get();
return view('user.index',['list'=>$list]);
} /**
* 加载添加用户页面
*/
public function add()
{
return view('user.add');
} /**
* 执行添加用户页面
*/
public function doAdd(Request $request)
{
$data = $request->post();
unset($data['_token']);
$id = DB::table('user')->insertGetId(
['name' => $data['name'], 'age' => $data['age']]
);
if($id){
echo '<script>alert("添加成功");window.location.href="/user";</script>'; }else{
echo '<script>alert("添加失败");window.location.href="/user";</script>'; } } /**
*
* 加载用户编辑页面
*
* @param $id [用户id]
*
*/ public function edit($id)
{
$list = DB::table('user')->where('id', $id)->first();
return view('user.edit',['list'=>$list]);
} /**
* 执行用户编辑
* @return boolean
*/
public function save(Request $request)
{
$data = $request->post();
$id = $data['id'];
unset($data['_token']);
unset($data['id']);
$res = DB::table('user')
->where('id', $id)
->update(['name'=>$data['name'],'age'=>$data['age']]);
if($res){
echo '<script>alert("更新成功");window.location.href="/user";</script>'; }else{
echo '<script>alert("更新失败");window.location.href="/user";</script>'; }
} /**
* 删除用户
*
* @param $id [用户id]
*
* @return boolean
*/ public function del( $id)
{
$res = DB::table('user')->where('id', $id)->delete();
if($res){
echo '<script>alert("删除成功");window.location.href="/user";</script>'; }else{
echo '<script>alert("修改失败");window.location.href="/user";</script>'; }
}
}
