這篇文章主要介紹了laravel5.3 vue 實現收藏夾功能，本文透過實例代碼給大家介紹的非常詳細,需要的朋友可以參考下
下面透過本文給大家介紹laravel5.3 vue 實作收藏夾功能，具體程式碼如下所述：
{
"private": true,
"scripts": {
"prod": "gulp --production",
"dev": "gulp watch"
},
"devDependencies": {
"bootstrap-sass": "^3.3.7",
"gulp": "^3.9.1",
"jquery": "^3.1.0",
"laravel-elixir": "^6.0.0-14",
"laravel-elixir-vue-2": "^0.2.0",
"laravel-elixir-webpack-official": "^1.0.2",
"lodash": "^4.16.2",
"vue": "^2.0.1",
"vue-resource": "^1.0.3"
}
}1.0.2 修改gulpfile.js
將原來的require('laravel-elixir-vue' ); 修改為require('laravel-elixir-vue-2');
const elixir = require('laravel-elixir');
require('laravel-elixir-vue-2');
/*

| file for our application, as well as publishing vendor resources.
|
*/
elixir(mix => {
mix.sass('app.scss')
.webpack('app.js');
});1.0.3 修改resource/assets/js/app.js
#將原來的el: 'body' 改為el: '#app'
const app = new Vue({
el: '#app'
});1.1 安裝npm 模組
（如果之前沒有執行此動作）
#npm install
1.2 建立模型及遷移
我們需要一個User模型（laravel附帶），一個Post模型和一個Favorite模型以及它們各自的遷移檔案。因為我們之前創建過了 Post 的模型，所以我們只需要創建一個 Favorite 模型。
php artisan make:model App\Models\Favorite -m
這會建立一個 Favorite
模型以及遷移檔案。
1.3 修改posts 遷移表及favorites 的up 方法
給posts 表在id 欄位後面新增一個user_id 欄位
php artisan make:migration add_userId_to_posts_table --table=posts
#修改database/migrations/2018_01_18_145843_adduser_table_togrations/2018_01_18_145843_adduser_table_togrations ##
public function up()
{
Schema::table('posts', function (Blueprint $table) {
$table->integer('user_id')->unsigned()->after('id');
});
}
database/migrations/2018_01_18_142146_create_favorites_table.php
public function up()
{
Schema::create('favorites', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->integer('post_id')->unsigned();
$table->timestamps();
});
}php artisan migrate
1.4 使用者認證
因為我們之前就已經創建過了，所以這裡就不需要重複創建了。 如果你沒有建立過使用者認證模組，你需要執行php artisan make:auth2. 完成搜藏夾功能
修改routes/web.php2.1 建立路由器Auth::routes();
Route::post('favorite/{post}', 'ArticleController@favoritePost');
Route::post('unfavorite/{post}', 'ArticleController@unFavoritePost');
Route::get('my_favorites', 'UsersController@myFavorites')->middleware('auth');public function favorites()
{
return $this->belongsToMany(Post::class, 'favorites', 'user_id', 'post_id')->withTimeStamps();
}2.3 建立文章控制器
因為我們之前已經建立過了，這裡也不需要建立了。 如果你沒有創建過，請執行php artisan make:controller ArticleController2.4 在文章控制器中加入favoritePost 和unFavoritePost 兩個方法注意要頭部要引入use Illuminate\Support\Facades\Auth;<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Post;
use Illuminate\Support\Facades\Auth;
class ArticleController extends Controller
{
public function index()
{
$data = Post::paginate(5);
return view('home.article.index', compact('data'));
}
public function show($id)
{
$data = Post::find($id);
return view('home.article.list', compact('data'));
}
public function favoritePost(Post $post)
{
Auth::user()->favorites()->attach($post->id);
return back();
}
public function unFavoritePost(Post $post)
{
Auth::user()->favorites()->detach($post->id);
return back();
}
} •引入axios模組resource/assets/js/bootstrap.js 在最後加入
import axios from 'axios'; window.axios = axios;
// resources/assets/js/components/Favorite.vue
<template>
<span>
<a href="#" rel="external nofollow" rel="external nofollow" v-if="isFavorited" @click.prevent="unFavorite(post)">
<i class="fa fa-heart"></i>
</a>
<a href="#" rel="external nofollow" rel="external nofollow" v-else @click.prevent="favorite(post)">
<i class="fa fa-heart-o"></i>
</a>
</span>
</template>
<script>
export default {
props: ['post', 'favorited'],
data: function() {
return {
isFavorited: '',
}
},
mounted() {
this.isFavorited = this.isFavorite ? true : false;
},
computed: {
isFavorite() {
return this.favorited;
},
},
methods: {
favorite(post) {
axios.post('/favorite/'+post)
.then(response => this.isFavorited = true)
.catch(response => console.log(response.data));
},
unFavorite(post) {
axios.post('/unfavorite/'+post)
.then(response => this.isFavorited = false)
.catch(response => console.log(response.data));
}
}
}
</script>
在視圖元件使用之前，我們先引入字體檔案resource/views/layouts/app.blade.php 頭部引入字體檔案
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css" />
並在app.blade .php 加入我的收藏夾連結
// 加在logout-form之后
<form id="logout-form" action="{{ url('/logout') }}" method="POST" style="display: none;">
{{ csrf_field() }}
</form>
<a href="{{ url('my_favorites') }}" rel="external nofollow" >我的收藏夹</a>使用元件
// resources/views/home/article/index.blade.php
if (Auth::check())
<p class="panel-footer">
<favorite
:post={{ $list->id }}
:favorited={{ $list->favorited() ? 'true' : 'false' }}
></favorite>
</p>endif
然後我們要建立favorited() 開啟app/Models/Post.php 增加favorited()方法
注意要在頭部引用命名空間use App\Models\Favorite;use Illuminate\Support\Facades\Auth;
public function favorited()
{
return (bool) Favorite::where('user_id', Auth::id())
->where('post_id', $this->id)
->first();
}引入Favorite.vue 元件resources/assets/js/app.js
Vue.component('favorite', require('./components/Favorite.vue'));
編譯
npm run dev
效果圖
3. 完成我的最愛
3.1 建立使用者控制器##
php artisan make:controller UsersController
app/Http/Controllers/UsersController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
class UsersController extends Controller
{
public function myFavorites()
{
$myFavorites = Auth::user()->favorites;
return view('users.my_favorites', compact('myFavorites'));
}
}// resources/views/users/my_favorites.blade.php
extends('layouts.app')
@section('content')
<p class="container">
<p class="row">
<p class="col-md-8 col-md-offset-2">
<p class="page-header">
<h3>My Favorites</h3>
</p>
@forelse ($myFavorites as $myFavorite)
<p class="panel panel-default">
<p class="panel-heading">
<a href="/article/{{ $myFavorite->id }}" rel="external nofollow" >
{{ $myFavorite->title }}
</a>
</p>
<p class="panel-body" style="max-height:300px;overflow:hidden;">
<img src="/uploads/{!! ($myFavorite->cover)[0] !!}" style="max-width:100%;overflow:hidden;" alt="">
</p>
@if (Auth::check())
<p class="panel-footer">
<favorite
:post={{ $myFavorite->id }}
:favorited={{ $myFavorite->favorited() ? 'true' : 'false' }}
></favorite>
</p>
@endif
</p>
@empty
<p>You have no favorite posts.</p>
@endforelse
</p>
</p>
</p>
@endsectionRoute::get('/', 'ArticleController@index');
上面是我整理給大家的，希望未來會對大家有幫助。
