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

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

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 = <<

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：

然后注册进laravel-admin,在app/Admin/bootstrap.php中添加以下代码：

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

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
";

$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!
' . '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!
' . '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

图1

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

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);

}

}

显示效果
