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

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>';

        }
    }
}

效果:

列表页

　　

添加页

编辑页

要搞其他东西,没做效果,直接弹窗提示
