laravel集成baum

本文主要是介绍laravel集成baum，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

安装git https://github.com/etrepat/baum 

运行install后会生成migrate，默认有id, parent_id, lft, rgt, depth, 其他根据自己需要自定

$table->increments('id');
$table->string('title')->comment('栏目名称');
$table->integer('parent_id')->nullable()->index()->comment('父级id'); //生成的
$table->string('keywords')->nullable();
$table->string('description')->nullable();
$table->integer('sort');
$table->integer('is_show')->comment('是否显示');
$table->integer('lft')->nullable()->index(); //生成的
$table->integer('rgt')->nullable()->index(); //生成的
$table->integer('depth')->nullable(); //生成的

模型：

model不继承Model，需要继承Node

<?phpnamespace App;use Illuminate\Database\Eloquent\Model;
use Baum;class Taxon extends  Baum\Node
{protected $table = 'taxons';protected $fillable=['title','parent_id','keywords','description', 'sort', 'is_show', 'lft', 'rgt', 'depth'];
}

自动填充

<?phpnamespace App\Jobs;use App\Taxon;
use Illuminate\Bus\Queueable;
use Illuminate\Foundation\Bus\Dispatchable;class TaxonFormFields
{use Dispatchable, Queueable;protected $id;protected $fieldList = ['title' => '','parent_id' => '','keywords' => '','description' => '','is_show' => '1','sort' => '50',];/*** Create a new job instance.** @return void*/public function __construct($id = null){$this->id = $id;}/*** Execute the job.** @return void*/public function handle(){$fields = $this->fieldList;if ($this->id) {$fields = Taxon::findOrFail($this->id);}return $fields;}
}

自定义request

<?phpnamespace App\Http\Requests;use Illuminate\Foundation\Http\FormRequest;class TaxonRequest extends FormRequest
{/*** Determine if the user is authorized to make this request.** @return bool*/public function authorize(){return true;}/*** Get the validation rules that apply to the request.** @return array*/public function rules(){return ['title' => 'required'];}/*** Return the fields and values to create a new post from*/public function fillData(){return ['title' => $this->title,'parent_id' => $this->parent_id,'keywords' => $this->keywords,'description' => $this->description,'is_show' => $this->is_show,'sort' => $this->sort,'lang' => 'zh-cn',];}
}

表单

<div class="form-group"><label for="taxon_title" class="col-sm-1 control-label">{{ trans('admin.title') }}</label><div class="col-sm-11"><input type="text" class="form-control" id="taxon_title" name="title" value="{{ $title }}"><p class="help-block">{{ $errors->first('title') }}</p></div>
</div>
<div class="form-group"><label for="taxon_keywords" class="col-sm-1 control-label">{{ trans('admin.keywords') }}</label><div class="col-sm-11"><input type="text" class="form-control" id="taxon_keywords" name="keywords" value="{{ $keywords }}"></div>
</div>
<div class="form-group"><label for="taxon_description" class="col-sm-1 control-label">{{ trans('admin.description') }}</label><div class="col-sm-11"><textarea class="form-control" id="taxon_description" name="description">{{ $description }}</textarea></div>
</div>
<div class="form-group"><label for="taxon_is_showe" class="col-sm-1 control-label">{{ trans('admin.is_show') }}</label><div class="col-sm-11"><input type="radio" id="taxon_is_show_1" name="is_show" value="{{ $is_show }}" @if($is_show == 1) checked="checked" @endif> {{ trans('admin.yes') }}<input type="radio" id="taxon_is_show_0" name="is_show" value="{{ $is_show }}" @if($is_show == 0) checked="checked" @endif> {{ trans('admin.no') }}</div>
</div>
<div class="form-group"><label for="taxon_sort" class="col-sm-1 control-label">{{ trans('admin.sort') }}</label><div class="col-sm-11"><input type="text" class="form-control" id="taxon_sort" name="sort" value="{{ $sort }}"></div>
</div>
<div class="form-group"><div class="col-sm-offset-1 col-sm-11"><input type="hidden" name="parent_id" value="{{ $parent_id }}" /><input type="submit" class="btn btn-default" value="提交" /></div>
</div>

添加分类

/*** 创建新表单页面** @return Response*/public function create(Request $request){$taxon = $this->dispatch(new TaxonFormFields());$parent_id = $request->get( 'parent_id', '');$taxon['parent_id'] = $parent_id;return view('admin/taxon/create', $taxon);}/*** 将新创建存储到存储器** @param Request $request* @return Response*/public function store(TaxonRequest $request){$parent = Taxon::find($request->input('parent_id'));$taxon = Taxon::create($request->fillData());$taxon->makeChildOf($parent);return redirect('admin/taxons');}

修改如果只修改数据，不修改分类结构就按照laravel修改就可以，

/*** 显示编辑表单页面** @param int $id* @return Response*/public function edit($id){$taxon = $this->dispatch(new TaxonFormFields($id));return view('admin/taxon/edit', $taxon);}/*** 在存储器中更新** @param Request $request* @param int $id* @return Response*/public function update(TaxonRequest $request, $id){$taxon = Taxon::findOrFail($id);$taxon = $taxon->fill($request->fillData());$taxon->save();return redirect('admin/taxons');}

删除

/*** 从存储器中移除** @param int $id* @return Response*/public function destroy($id){$taxon = Taxon::findOrFail($id);$taxon->delete();return response()->json(['error_num' => '0', 'link' => '/admin/taxons']);}
