小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.
好久沒玩laravel了，5.6玩下（三）
好了，基礎(chǔ)的測試通了，咱們開始增刪改了
思路整理
先創(chuàng)建項目功能控制器
然后設(shè)置路由訪問規(guī)則
然后開發(fā)項目的增刪改功能
?
?
1 先創(chuàng)建項目的控制器
php artisan make:controller ProjectsController生成的文件在?blog\app\Http\Controllers ?這個目錄下?
?
2 設(shè)置路由訪問規(guī)則，找到文件? blog\app\routes\web.php 添加如下代碼
Route::resource('projects', 'ProjectsController');Route::get('projects/show/{id}', 'ProjectsController@show');意思是可以訪問projects的控制器
?
3 填充 項目控制器?
blog\app\http\Controllers\ProjectsController
<?phpnamespace App\Http\Controllers;use Illuminate\Http\Request; use App\Projects;class ProjectsController extends Controller {/***保存*/public function store(Request $request){$projects = new Projects;$projects->name = $request->input('name');$projects->author = $request->input('author');$projects->description = $request->input('description');if ($projects->save()) {return redirect('projects');} else {return back()->withInput()->withErrors('添加失敗，請重試');}}//更新public function update(Request $request,$id){$projects = Projects::find($id); $projects->name = $request->input('name');$projects->author = $request->input('author');$projects->description = $request->input('description');if ($projects->save()) {return redirect('projects');} else {return back()->withInput()->withErrors('更新失敗，請重試');}}//添加public function create(){return view('projects.create');}//編輯public function edit($id){$project=Projects::find($id);return view('projects.edit',compact('project'));}//刪除public function destroy($id){$project = Projects::find($id);$project->delete();return redirect('projects');}//列表public function index(){$projects = Projects::all();return view('projects.index',compact('projects'));}//顯示public function show($id){$project=Projects::find($id);return view('projects.show',compact('project'));} }?
4?設(shè)置模板頁
模板頁面位置在blog\resources\views 這個位置
1）在views\layouts\app.blade.php ?改成如下代碼
<!DOCTYPE html> <html lang="{{ str_replace('_', '-', app()->getLocale()) }}"> <head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge"><meta name="viewport" content="width=device-width, initial-scale=1"><!-- CSRF Token --><meta name="csrf-token" content="{{ csrf_token() }}"><title>{{ config('app.name', 'Laravel') }}</title><!-- Scripts --><script src="{{ asset('js/app.js') }}" defer></script><!-- Fonts --><link rel="dns-prefetch" href="https://fonts.gstatic.com"><link href="https://fonts.googleapis.com/css?family=Raleway:300,400,600" rel="stylesheet" type="text/css"><!-- Styles --><link href="{{ asset('css/app.css') }}" rel="stylesheet"> </head> <body><div id="app"><nav class="navbar navbar-expand-md navbar-light navbar-laravel"><div class="container"><a class="navbar-brand" href="{{ url('/') }}">{{ config('app.name', 'Laravel') }}</a><button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="{{ __('Toggle navigation') }}"><span class="navbar-toggler-icon"></span></button><div class="collapse navbar-collapse" id="navbarSupportedContent"><!-- Left Side Of Navbar --><ul class="navbar-nav mr-auto"> <li><a href="/home">后臺首頁 </a></li><li><a href="/projects">管理項目</a></li></ul><!-- Right Side Of Navbar --><ul class="navbar-nav ml-auto"><!-- Authentication Links -->@guest<li class="nav-item"><a class="nav-link" href="{{ route('login') }}">{{ __('Login') }}</a></li><li class="nav-item"><a class="nav-link" href="{{ route('register') }}">{{ __('Register') }}</a></li>@else<li class="nav-item dropdown"><a id="navbarDropdown" class="nav-link dropdown-toggle" href="#" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" v-pre>{{ Auth::user()->name }} <span class="caret"></span></a><div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdown"><a class="dropdown-item" href="{{ route('logout') }}"onclick="event.preventDefault();document.getElementById('logout-form').submit();">{{ __('Logout') }}</a><form id="logout-form" action="{{ route('logout') }}" method="POST" style="display: none;">@csrf</form></div></li>@endguest</ul></div></div></nav><main class="py-4">@yield('content')</main></div> </body> </html>其實就是在頂部增加2個鏈接? 一個項目管理? 一個后臺首頁? 其他都是原來的代碼
?
2）
我們新建一個projects文件夾
新建4個模板文件
create.blade.php
@extends('layouts.app')@section('content') <div class="container"> <div class="row"><div class="col-md-10 col-md-offset-1"><div class="panel panel-default"><div class="panel-heading">新增項目</div><div class="panel-body">@if (count($errors) > 0)<div class="alert alert-danger"><strong>Whoops!</strong> There were some problems with your input.<br><br><ul>@foreach ($errors->all() as $error)<li>{{ $error }}</li>@endforeach</ul></div>@endif<form action="{{ URL('projects') }}" enctype="multipart/form-data" method="POST"><input type="hidden" name="_token" value="{{ csrf_token() }}">項目標(biāo)題：<input type="text" name="name" class="form-control" required="required"><br>項目作者：<input type="text" name="author" class="form-control" required="required"><br>項目內(nèi)容： <textarea name="description" rows="10" class="form-control"></textarea><br><button class="btn btn-lg btn-info">新增項目</button></form></div></div></div></div> </div> @endsection?

show.blade.php
@extends('layouts.app')@section('content') <div class="container"> <div class="row"><div class="col-md-10 col-md-offset-1"><div class="panel panel-default"><div class="panel-heading">顯示項目</div><div class="panel-body">@if (count($errors) > 0)<div class="alert alert-danger"><strong>Whoops!</strong> There were some problems with your input.<br><br><ul>@foreach ($errors->all() as $error)<li>{{ $error }}</li>@endforeach</ul></div>@endif<input name="_method" type="hidden" value="PUT"><input type="hidden" name="_token" value="{{ csrf_token() }}">項目標(biāo)題：{{ $project->name }}<br>項目作者：{{ $project->author }}<br> <br><br>項目內(nèi)容：{{ $project->description }}<br></div></div></div></div> </div> @endsection?
