改了个BUG，关于分类列表页面左侧分类显示问题

这个是原始图片，问题就是左侧分类列表，理论上点击一级分类，左侧应该出二级分类，点击二级分类左侧应该出三级分类，依次往下，点击最小层分类显示同级分类。但是现在点击二级分类或者三级分类显示为空，随排查问题，发现在

在CategoryMysqldb.php里面，第514行 $id = $category['id']; 应该改为 $id = $category['_id'];原因是第486行 '_id' => $currentId,Key值是"_id",解决了第一层和最终层问题，发现中间层还没有解决，再查发现第476行函数getFilterCategory原始代码如下

    public function getFilterCategory($category_id, $parent_id)
    {
        $returnData = [];
        $primaryKey = $this->getPrimaryKey();
        $currentCategory = $this->_categoryModel->findOne($category_id);
        $currentCategory =$this->unserializeData($currentCategory) ;
        $currentUrlKey = $currentCategory['url_key'];
        $currentName = $currentCategory['name'];
        $currentId = $currentCategory['id'];
        $returnData['current'] = [
            '_id'        => $currentId,
            'name'       => $currentName,
            'url_key'    => $currentUrlKey,
            'parent_id'  => $currentCategory['parent_id'],
        ];
        if ($currentCategory['parent_id']) {
            $allParent = $this->getParentCategory($currentCategory['parent_id']);
            $allParent[] = $returnData['current'];
            $data = $this->getAllParentCate($allParent);
        } else {
            $data = $this->getOneLevelCateChild($returnData['current']);
        }
        return $data;
    }

分类信息传递混乱，改为如下代码

public function getFilterCategory($category_id, $parent_id)
    {
        $returnData = [];
        $primaryKey = $this->getPrimaryKey();
        $currentCategory = $this->_categoryModel->findOne($category_id);
        $currentCategory =$this->unserializeData($currentCategory) ;
        $currentUrlKey = $currentCategory['url_key'];
        $currentName = $currentCategory['name'];
        $currentId = $currentCategory['id'];
        $returnData['current'] = [
            '_id'        => $currentId,
            'name'       => $currentName,
            'url_key'    => $currentUrlKey,
            'parent_id'  => $currentCategory['parent_id'],
        ];
        if ($currentCategory['parent_id']) {
            $allChild = $this->getChildCategory( $currentId);
            if(is_array($allChild) && !empty($allChild)){
                $data = $this->getAllParentCate($allChild);
            }else{
                $allParent[] = $returnData['current'];
                $data = $this->getAllParentCate($allParent);
            }

        } else {
            $data = $this->getOneLevelCateChild($returnData['current']);
        }

        return $data;
    }

完美解决
