篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了转载laravel中使用WangEditor及多图上传相关的知识，希望对你有一定的参考价值。

1. 创建项目及安装所需安装包

1.1 创建项目

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

1.2 创建数据库及配置文件

vim .env

1.3 安装中文包

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

安装之后将语言包移动到对应位置就好了，语言包默认位置是resources/lang

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

修改config/app.php将local的值改为zh-CN

1.4 安装`laravel-admin`

composer 安装

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

在config/app.php加入ServiceProvider:

Encore\Admin\Providers\AdminServiceProvider::class

发布资源

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

安装

php artisan admin:install

1.5 快速生成前端登录注册模块

php artisan make:auth

执行迁移

php artisan migrate

2. 快速生成文章管理

2.1 创建迁移表

php artisan make:migration create_posts_table --create=posts

2.2 修改迁移表`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 执行迁移

php artisan migrate

2.4 创建模型和控制器

模型

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

控制器

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

2.5 新增文章后台路由

Admin/routes.php

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

2.6 修改`app/Admin/PostController.php`里面的form和grid两个方法

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

            $grid->id(‘ID‘)->sortable();
            $grid->title(‘标题‘);
            $grid->subtitle(‘副标题‘);
            $grid->type(‘类型‘)->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(‘内容‘)->limit(100);
            $grid->created_at(‘创建时间‘);
            $grid->updated_at(‘修改时间‘);
        });
    }

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

            $form->display(‘id‘, ‘ID‘);
            $form->text(‘title‘, ‘标题‘);
            $form->textarea(‘subtitle‘, ‘副标题‘)->rows(3);
            $form->select(‘type‘, ‘类型‘)->options([
                ‘0‘ => ‘php‘,
                ‘1‘ => ‘laravel‘,
                ‘2‘ => ‘javascript‘,
                ‘3‘ => ‘python‘,
                ‘4‘ => ‘golang‘,
                ‘5‘ => ‘linux‘,
                ‘9‘ => ‘other‘
            ]);
            $form->image(‘cover‘, ‘封面‘);
            $form->editor(‘content‘, ‘内容‘);
            $form->display(‘created_at‘, ‘创建时间‘);
            $form->display(‘updated_at‘, ‘修改时间‘);
        });
    }

3. 集成`WangEditor`编辑器

3.1 移除已有组件

修改app/Admin/bootstrap.php

<?php

use Encore\Admin\Form;

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

// or

Form::forget([‘map‘, ‘editor‘]);

3.2 集成富文本编辑器wangEditor

先下载前端库文件wangEditor，解压到目录public/vendor/wangEditor-3.0.9。

然后新建组件类app/Admin/Extensions/WangEditor.php。关于WangEditor设置部分请阅读官方文档

<?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;
// 上传路径
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("最多可以上传4张图片");
                break;
            case 5:
                toastr.error("请选择一个文件");
                break;
            case 4:
                toastr.error("上传失败");
                break;
            case 3:
                toastr.error(result[‘info‘]);
                break;
            case 2:
                toastr.error("文件类型不合法");
                break;
            case 1:
                toastr.error(result[‘info‘]);
                break;
        }
    }
}
editor.create();

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

EOT;
        return parent::render();

    }
}

新建视图文件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>
然后注册进laravel-admin,在app/Admin/bootstrap.php中添加以下代码：

<?php

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

Form::extend(‘editor‘, WangEditor::class);
调用：

$form->editor(‘body‘);

3.3 完成`WangEditor`图片上传

3.3.1 创建上传路由`routes/web.php`

Route::post(‘/uploadFile‘, ‘[email protected]‘);

3.3.2 创建上传文件控制器`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‘ => ‘最多可以上传25张图片‘]);
            }
            $m = 0;
            $k = 0;
            for ($i = 0; $i <= $len; $i++) {
                // $n 表示第几张图片
                $n = $i + 1;
                if ($file[$i]->isValid()) {
                    if (in_array(strtolower($file[$i]->extension()), [‘jpeg‘, ‘jpg‘, ‘gif‘, ‘gpeg‘, ‘png‘])) {
                        $picname = $file[$i]->getClientOriginalName();//获取上传原文件名
                        $ext = $file[$i]->getClientOriginalExtension();//获取上传文件的后缀名
                        // 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‘ => ‘上传成功‘, ‘newFileName‘ => $newFileName ]);

                        } else {
                            $k = $k + 1;
                            // return response()->json([‘ResultData‘ => 4, ‘info‘ => ‘上传失败‘]);
                        }
                        $msg = $m . "张图片上传成功 " . $k . "张图片上传失败<br>";
                        $return[] = [‘ResultData‘ => 0, ‘info‘ => $msg, ‘newFileName‘ => $newFileName];
                    } else {
                        return response()->json([‘ResultData‘ => 3, ‘info‘ => ‘第‘ . $n . ‘张图片后缀名不合法!<br/>‘ . ‘只支持jpeg/jpg/png/gif格式‘]);
                    }
                } else {
                    return response()->json([‘ResultData‘ => 1, ‘info‘ => ‘第‘ . $n . ‘张图片超过最大限制!<br/>‘ . ‘图片最大支持2M‘]);
                }
            }

        } else {
            return response()->json([‘ResultData‘ => 5, ‘info‘ => ‘请选择文件‘]);
        }
        return $return;
    }
}

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

 ‘upload‘  => [

        ‘disk‘ => ‘admin‘,

        ‘directory‘  => [
            ‘image‘  => ‘image‘,
            ‘file‘   => ‘file‘,
        ],
        // 将upload改为uploads
        ‘host‘ => ‘http://localhost:8000/uploads/‘,
    ],

预览图技术分享图片

可以看出WangEditor上传多图是没有问题的可是有时候我们想给文章配多个封面图怎么办？下面我们就来完成，laravel-admin的多图上传。

4. laravel-admin 多图上传

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

将$form->image(‘cover‘, ‘封面‘); 修改为$form->multipleImage(‘cover‘, ‘封面‘);

4.2 创建图片修改器

laravel修改器使用说明，请阅读相关说明文档在app/Models/Post.php里增加setCoverAttribute() 和setCoverAttribute两个方法

<?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);
    }
}
