<?phpnamespace AppAdminModels;use EncoreAdminTraitsAdminBuilder;use EncoreAdminTraitsModelTree;use IlluminateDatabaseEloquentModel;class Category extends Model{ use ModelTree, AdminBuilder; protected $table = 'category'; public function __construct(array $attributes = []) { parent::__construct($attributes);//这里根据自己的字段修改 $this->setParentColumn('parent_id'); $this->setOrderColumn('sort'); $this->setTitleColumn('name'); } }修改控制文件CategoryController.php
<?phpnamespace AppAdminControllers;use AppAdminModelsCategory;use EncoreAdminControllersAdminController;use EncoreAdminFacadesAdmin;use EncoreAdminLayoutContent;use EncoreAdminShow;class CategoryController extends AdminController{ /** * Title for current resource. * * @var string */ protected $title = '商品分类管理'; public function index(Content $content) { return Admin::content(function ($content) { $content->header('商品分类管理'); $content->body(Category::tree(function ($tree) { $tree->branch(function ($branch) { $src = config('admin.upload.host') . '/' . $branch['image']; $logo = "<img src='$src' style='max-width:30px;max-height:30px' class='img'/>"; return "{$branch['id']} - {$branch['name']} $logo"; }); })); }); }//下面是自己的代码//....... }添加路由app/Admin/routes.php
