Laravel admin 实现分类树/模型树

修改模型Category.php

<?php  namespace 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

<?php  namespace 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

$router->resource('categories',CategoryController::class);

select中使用分类树

$form->select('parent_id', __('Parent id'))->options(Category::selectOptions())->default(1);
