fastadmin,如何配置多级栏目下拉

直接上案例演示,情景分析,我这里有一个文章,后台需要调用文章栏目下拉框使用.文章栏目存在多级.

我看到这个多级下拉功能,在权限管理,角色组中,有这个功能,通过分析,把代码抄过来了..

首先,我们在common模块中的ArticleCategory模型中,写一个查询所有栏目的方法.

项目\application\common\model\ArticleCategory.php

/**
     * 返回文章栏目列表
     * @return array|false|\PDOStatement|string|\think\Collection
     */
    public function getArticleCategoryLists()
    {
        $result=[];
        $list=$this->where(["status"=>1])->order("id","asc")->field(["id","pid","name"])->select();
        $result=$list;

        return $result;
    }

随后,在后台控制器的初始化函数中,把这个数据,给拼装一下,项目\application\admin\controller\Articles.php

   public function _initialize()
    {
        parent::_initialize();
        $this->model = new \app\common\model\Articles;

        $ArticleCategory=new ArticleCategory();
        $articleCategoryLists = $ArticleCategory->getArticleCategoryLists();


        Tree::instance()->init($articleCategoryLists);
        $result = Tree::instance()->getTreeList(Tree::instance()->getTreeArray(0));

        $categoryLists=[];
        foreach ($result as $k => $v) {
            $categoryLists[$v['id']] = $v['name'];
        }


        $this->view->assign('categoryLists', $categoryLists);


    }

这里调用了fastadmin自带的用了Tree方法,把一个二维数组,拼接成(id=>名称)的一维数组,这样在前端通过控件,直接调用.

use fast\Tree;

新增

{:build_select('row[pid]', $categoryLists, 0, ['class'=>'form-control selectpicker', 'data-rule'=>'required'])}

修改

{:build_select('row[pid]', $categoryLists, $row['pid'], ['class'=>'form-control selectpicker', 'data-rule'=>'required'])}

实现效果
