laravel中使用WangEditor及多图上传

栏目: PHP · 发布时间: 6年前

内容简介：laravel中使用WangEditor及多图上传

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', 'UploadsController@uploadImg');

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

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);
    }
}
