1. 建立項目及安裝所需安裝包

1.1 建立項目

composer create-project laravel/laravel=5.3 blog_wangeditor --prefer-dist

1.2 建立數據庫及配置文件

vim .env

1.3 安裝中文包

composer require "caouecs/laravel-lang:~3.0"

安裝以後將語言包移動到對應位置就行了，語言包默認位置是resources/langjavascript

cp -a vendor/caouecs/laravel-lang/src/zh-CN resources/lang

修改config/app.php將local的值改成zh-CNphp

1.4 安裝`laravel-admin`

composer 安裝css

composer require encore/laravel-admin "1.3.*"

在config/app.php加入ServiceProvider:html

Encore\Admin\Providers\AdminServiceProvider::class

發佈資源前端

php artisan vendor:publish --tag=laravel-admin

安裝java

php artisan admin:install

1.5 快速生成前端登陸註冊模塊

php artisan make:auth

執行遷移python

php artisan migrate

2. 快速生成文章管理

2.1 建立遷移表

php artisan make:migration create_posts_table --create=posts

2.2 修改遷移表`database/2018_01_14_191442_create_posts_table.php`

public function up() { Schema::create('posts', function (Blueprint $table) { $table->increments('id'); $table->text('title'); $table->text('subtitle'); $table->text('cover'); $table->enum('type', ['0', '1', '2', '3', '4', '5', '9'])->default('0'); $table->text('content'); $table->timestamps(); }); }

2.3 執行遷移

php artisan migrate

2.4 建立模型和控制器

模型linux

php artisan make:model App\\Models\\Post

控制器nginx

php artisan admin:make PostController --model=App\\Models\\Post

2.5 新增文章後臺路由

Admin/routes.php

$router->resource('/post', 'PostController');

2.6 修改`app/Admin/PostController.php`裏面的form和grid兩個方法

 protected function grid()
    {
        return Admin::grid(Post::class, function (Grid $grid) {

            $grid->id('ID')->sortable();
            $grid->title('標題');
            $grid->subtitle('副標題');
            $grid->type('類型')->options([
                '0' => 'php',
                '1' => 'laravel',
                '2' => 'javascript',
                '3' => 'python',
                '4' => 'golang',
                '5' => 'linux',
                '9' => 'other'
            ]);
             $grid->cover('封面')->image('/uploads', 100, 100);
            $grid->content('內容')->limit(100);
            $grid->created_at('建立時間');
            $grid->updated_at('修改時間');
        });
    }

    protected function form()
    {
        return Admin::form(Post::class, function (Form $form) {

            $form->display('id', 'ID');
            $form->text('title', '標題');
            $form->textarea('subtitle', '副標題')->rows(3);
            $form->select('type', '類型')->options([
                '0' => 'php',
                '1' => 'laravel',
                '2' => 'javascript',
                '3' => 'python',
                '4' => 'golang',
                '5' => 'linux',
                '9' => 'other'
            ]);
            $form->image('cover', '封面');
            $form->editor('content', '內容');
            $form->display('created_at', '建立時間');
            $form->display('updated_at', '修改時間');
        });
    }

3. 集成`WangEditor`編輯器

3.1 移除已有組件

修改app/Admin/bootstrap.phplaravel

<?php

use Encore\Admin\Form;

Form::forget('map');
Form::forget('editor');

// or

Form::forget(['map', 'editor']);

3.2 集成富文本編輯器wangEditor

先下載前端庫文件wangEditor，解壓到目錄public/vendor/wangEditor-3.0.9。

而後新建組件類app/Admin/Extensions/WangEditor.php。關於WangEditor設置部分請閱讀官方文檔

<?php

namespace App\Admin\Extensions;

use Encore\Admin\Form\Field;

class WangEditor extends Field
{
    protected $view = 'admin.wang-editor';

    protected static $css = [
        '/vendor/wangEditor-3.0.9/release/wangEditor.min.css',
    ];

    protected static $js = [
        '/vendor/wangEditor-3.0.9/release/wangEditor.min.js',
    ];

    public function render()
    {
        $name = $this->formatName($this->column);

        $this->script = <<<EOT

var E = window.wangEditor
var editor = new E('#{$this->id}');
editor.customConfig.uploadFileName = 'mypic[]';
editor.customConfig.uploadImgHeaders = {
    'X-CSRF-TOKEN': $('input[name="_token"]').val()
}
editor.customConfig.zIndex = 0;
// 上傳路徑
editor.customConfig.uploadImgServer = '/uploadFile';
editor.customConfig.onchange = function (html) {
    $('input[name=$name]').val(html);
}
editor.customConfig.uploadImgHooks = {
    customInsert: function (insertImg, result, editor) {
        if (typeof(result.length) != "undefined") {
            for (var i = 0; i <= result.length - 1; i++) {
                var j = i;
                var url = result[i].newFileName;
                insertImg(url);
            }
            toastr.success(result[j]['info']);
        }

        switch (result['ResultData']) {
            case 6:
                toastr.error("最多能夠上傳4張圖片");
                break;
            case 5:
                toastr.error("請選擇一個文件");
                break;
            case 4:
                toastr.error("上傳失敗");
                break;
            case 3:
                toastr.error(result['info']);
                break;
            case 2:
                toastr.error("文件類型不合法");
                break;
            case 1:
                toastr.error(result['info']);
                break;
        }
    }
}
editor.create();

// var editor = new wangEditor('{$this->id}');
//     editor.create();

EOT;
        return parent::render();

    }
}

新建視圖文件resources/views/admin/wang-editor.blade.php：

<div class="form-group {!! !$errors->has($label) ?: 'has-error' !!}">

    <label for="{{$id}}" class="col-sm-2 control-label">{{$label}}</label>

    <div class="col-sm-{{$width['field']}}">

        @include('admin::form.error')

        <div id="{{$id}}" style="width: 100%; height: 100%;">
            <p>{!! old($column, $value) !!}</p>
        </div>

        <input type="hidden" name="{{$name}}" value="{{ old($column, $value) }}" />

    </div>
</div>
而後註冊進laravel-admin,在app/Admin/bootstrap.php中添加如下代碼：

<?php

use App\Admin\Extensions\WangEditor;
use Encore\Admin\Form;

Form::extend('editor', WangEditor::class);
調用：

$form->editor('body');

3.3 完成`WangEditor`圖片上傳

3.3.1 建立上傳路由`routes/web.php`

Route::post('/uploadFile', 'UploadsController@uploadImg');

3.3.2 建立上傳文件控制器`UploadsController`

php artisan make:controller UploadsController

修改app\Controllers\UploadsController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class UploadsController extends Controller
{
    public function uploadImg(Request $request)
    {
        $file = $request->file("mypic");
        // dd($file);
        if (!empty($file)) {
            foreach ($file as $key => $value) {
                $len = $key;
            }
            if ($len > 25) {
                return response()->json(['ResultData' => 6, 'info' => '最多能夠上傳25張圖片']);
            }
            $m = 0;
            $k = 0;
            for ($i = 0; $i <= $len; $i++) {
                // $n 表示第幾張圖片
                $n = $i + 1;
                if ($file[$i]->isValid()) {
                    if (in_array(strtolower($file[$i]->extension()), ['jpeg', 'jpg', 'gif', 'gpeg', 'png'])) {
                        $picname = $file[$i]->getClientOriginalName();//獲取上傳原文件名
                        $ext = $file[$i]->getClientOriginalExtension();//獲取上傳文件的後綴名
                        // 重命名
                        $filename = time() . str_random(6) . "." . $ext;
                        if ($file[$i]->move("uploads/images", $filename)) {
                            $newFileName = '/' . "uploads/images" . '/' . $filename;
                            $m = $m + 1;
                            // return response()->json(['ResultData' => 0, 'info' => '上傳成功', 'newFileName' => $newFileName ]);

                        } else {
                            $k = $k + 1;
                            // return response()->json(['ResultData' => 4, 'info' => '上傳失敗']);
                        }
                        $msg = $m . "張圖片上傳成功 " . $k . "張圖片上傳失敗<br>";
                        $return[] = ['ResultData' => 0, 'info' => $msg, 'newFileName' => $newFileName];
                    } else {
                        return response()->json(['ResultData' => 3, 'info' => '第' . $n . '張圖片後綴名不合法!<br/>' . '只支持jpeg/jpg/png/gif格式']);
                    }
                } else {
                    return response()->json(['ResultData' => 1, 'info' => '第' . $n . '張圖片超過最大限制!<br/>' . '圖片最大支持2M']);
                }
            }

        } else {
            return response()->json(['ResultData' => 5, 'info' => '請選擇文件']);
        }
        return $return;
    }
}

3.3.3 修改`config/admin.php` upload裏面的`host`

 'upload'  => [

        'disk' => 'admin',

        'directory'  => [
            'image'  => 'image',
            'file'   => 'file',
        ],
        // 將upload改成uploads
        'host' => 'http://localhost:8000/uploads/',
    ],

預覽圖

能夠看出WangEditor上傳多圖是沒有問題的但是有時候咱們想給文章配多個封面圖怎麼辦？下面咱們就來完成，laravel-admin的多圖上傳。

4. laravel-admin 多圖上傳

4.1 修改`app/Admin/PostController`裏面的`form()`方法

將$form->image('cover', '封面'); 修改成$form->multipleImage('cover', '封面');

4.2 建立圖片修改器

laravel修改器使用說明，請閱讀相關說明文檔在app/Models/Post.php裏增長setCoverAttribute() 和setCoverAttribute兩個方法

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    public function setCoverAttribute($cover)
    {
        if (is_array($cover)) {
            $this->attributes['cover'] = json_encode($cover);
        }
    }

    public function getCoverAttribute($cover)
    {
        return json_decode($cover, true);
    }
}
