Yii 1.從類別及其子類別獲取產品[無限制嵌套]

Question

我正在開發一些基於目錄的項目，其中包含無限嵌套（實際上，最高級別爲3，我猜，但必須是動態反正）。

讓我告訴就要做：

OrganizationCategory型號：

public function relations() 
{ 
    return array(
     'organizations' => array(self::HAS_MANY, 'Organization', 'organization_category_id'), 
     'parent' => array(self::BELONGS_TO, 'OrganizationCategory', 'category_parent_id'), 
     'children' => array(self::HAS_MANY, 'OrganizationCategory', 'category_parent_id'), 
    ); 
} 

public static function getParentCategories() 
{ 
    if (is_null(self::$categories)) 
    { 
     self::$categories = array(); 
     $criteria = new CDbCriteria(); 
     $criteria->order = 't.category_title'; 
     $criteria->condition = "t.category_parent_id IS NULL"; 
     $arr = self::model()->with('children')->findAll($criteria); 
     foreach ($arr as $item) 
      self::$categories[$item->primaryKey] = $item; 
    } 

    return self::$categories; 
} 

public static function createTree($children, $counter) 
{ 
    $tree = ''; 

    if(count($children)){ 

     $tree .= CHtml::tag('ul', array('class'=>'menu_open_'.$counter)); 

     foreach($children as $child): 

      $childrenSub = self::createTree($child->children, $counter+1); 

      $tree .= CHtml::tag('li', (empty($childrenSub) ? array('class'=>'no_child_li') : array())); 

      $organizations = Organization::model()->findByAttributes(array('organization_category_id'=>$child->category_id)); 

      $tree .= CHtml::link($child->category_title, array('organizationCategory/view', 'slug'=>$child->category_slug)); 

      $tree .= $childrenSub; 
      $tree .=CHtml::closeTag('li'); 

     endforeach; 

     $tree .= CHtml::closeTag('ul'); 

    } 

    return $tree; 
} 

CategoryController：

public function actionView($slug = '') 
{ 
    $model = $this->loadModelSlug($slug); 

    $organizationsList = Organization::getOrganizations($model->category_id); 

    $this->pageTitle=$model->category_title; 
    Yii::app()->clientScript->registerMetaTag($model->meta_description, 'description'); 
    Yii::app()->clientScript->registerMetaTag($model->meta_keywords, 'keywords'); 

    $this->render('view',array(
     'model'=>$model, 
     'organizationsList'=>$organizationsList, 
    )); 
} 

組織模型getOrganizations（）：

public static function getOrganizations($category_id) { 

    $criteria = new CDbCriteria; 
    $criteria->condition = 'organization_category_id = :cat_id'; 
    $criteria->params = array(':cat_id'=>$category_id); 
    $result = self::model()->findAll($criteria); 

    return $result; 
} 

貓egory view.php

<?php if(!empty($model->children)) { 
echo OrganizationCategory::model()->createTree($model->children, 1); 
} ?> 

<?php $i=1; foreach($model->organizations as $organization): ?> 
    blah blah blah 
<?php $i++; endforeach; ?> 

正如您可以猜到，現在，我只能得到這些產品，這是僅與當前顯示的類別相關聯。

我的目標是從類別及其所有子類別 - >子類別 - >子類別獲取產品。

我試圖找到解決方案几乎無處不在，但仍然無法在我的項目中實現這個瑣碎的任務。

我希望提供的任何幫助，感謝

對於其他人誰也有興趣在這個問題上，我已經解決了它在一個這樣的方式：

在類別控制器視圖動作我打電話：

$model = $this->loadModelSlug($slug); 
$organizationsList = Organization::getOrganizationsFromSubcategories($model); 

在組織模式：

public static function getOrganizationsFromSubcategories($category) { 

    $childCategoriesIds = OrganizationCategory::getChildCategoriesIds($category); 

    $criteria = new CDbCriteria(); 
    $criteria->addInCondition('organization_category_id', $childCategoriesIds); 
    $result = self::model()->findAll($criteria); 

    return $result; 
} 

而且，國際泳聯lly，在組織類別：

public static function getChildCategoriesIds($category) 
{ 
    $arr = array($category->primaryKey); 

    if (!empty($category->children)) 
     foreach ($category->children as $child_category) $arr = array_merge($arr, self::getChildCategoriesIds($child_category)); 

    return $arr; 
}
