Magento 产品按类别

Question

有谁知道我如何从Magento 的视图文件中获取属于特定类别的产品列表？

Answer 1

您可以使用 magento 对象进行过滤。

例子：

$categoryId = 123; // a category id that you can get from admin
$category = Mage::getModel('catalog/category')->load($categoryId);

$products = Mage::getModel('catalog/product')
    ->getCollection()
    ->addCategoryFilter($category)
    ->load();

print_r($products);

Answer 2

这完全取决于你在哪个视图中。;-)

首先，我希望你留在你的模板集中（在我的例子中是默认的）。

将此作为示例：

<?php
$_cat         = $this->getCurrentCategory();
$_parent      = $_cat->getParentCategory();
$_categories  = $_parent->getChildren();

/* @var $category Mage_Catalog_Model_Category */
$collection = Mage::getModel('catalog/category')->getCollection();
/* @var $collection Mage_Catalog_Model_Resource_Eav_Mysql4_Category_Collection */
$collection->addAttributeToSelect('url_key')
    ->addAttributeToSelect('name')
    ->addAttributeToSelect('is_anchor')
    ->addAttributeToFilter('is_active', 1)
    ->addIdFilter($_categories)
    ->setOrder('position', 'ASC')
    ->joinUrlRewrite()
    ->load();

$productCollection = Mage::getResourceModel('catalog/product_collection');
$layer             = Mage::getSingleton('catalog/layer');
$layer->prepareProductCollection($productCollection);
$productCollection->addCountToCategories($collection);
// $productCollection should be ready here ;-)
?>

我正在使用上面的代码在我的模板中显示姐妹类别 - 这并不理想，但它有效。

这有点像 hack，因为我还没有时间学习所有的布局 XML 疯狂。否则，如果您使用 XML，则需要牢记——这完全取决于您所处的位置。 在哪里表示模板文件，本质上也是布局（在 app/design/frontend/default/default/layout/* 方面）。

我知道这并不多，但我希望它可以帮助您入门。

Answer 3

这是从任何特定类别获取产品的代码。您也可以在视图文件中使用它。

// if you want to display products from current category
$category = Mage::registry('current_category'); 

// if you want to display products from any specific category
$categoryId = 10;
$category = Mage::getModel('catalog/category')->load($categoryId);

$productCollection = Mage::getResourceModel('catalog/product_collection')
                                 ->addCategoryFilter($category);

// printing products name
foreach ($productCollection as $product) {
    echo $product->getName(); 
    echo "<br />";
}

<?php
$c_id = 2;
$category = new Mage_Catalog_Model_Category();
$category->load($c_id);
$collection = $category->getProductCollection();
$collection->addAttributeToSelect('*');
foreach ($collection as $_product) { ?>
<a href="<?php echo $_product->getProductUrl(); ?>"><?php echo $_product->getName(); ?></a>
<?php } ?>

Answer 5

我非常需要同样的东西。这是我的做法：

$prod_whole = array();
if(!empty($_menu)) //$_menu = array of Categories with some basic info
foreach($_menu as $v)
{
    if($v['name']=='HOME')
    continue;

    $cat_id = $v['id'];

    #/ Setup Products
    $category = Mage::getModel('catalog/category')->load($cat_id);

    $collection = Mage::getModel('catalog/product')->getCollection()
    ->addAttributeToSelect('*') // select all attributes
    ->addCategoryFilter($category)
    ->setPageSize(8) // limit number of results returned
    ->setCurPage(0)
    ->load()
    ;


    $prod_collection = array();
    foreach ($collection as $product)
    {
      $prod_collection_1 = array();

      #/ Basic Info
      $prod_collection_1['id'] = $product->getId();
      $prod_collection_1['name'] = $product->getName();
      $prod_collection_1['price'] = (float) $product->getPrice();
      //$prod_collection_1['desc'] = $product->getDescription();
      //$prod_collection_1['short'] = $product->getShortDescription();
      $prod_collection_1['type'] = $product->getTypeId();
      $prod_collection_1['status'] = $product->getStatus();
      $prod_collection_1['special_price'] =  $product->getSpecialPrice();
      $prod_collection_1['direct_url'] =  $product->getProductUrl();


      #/ getCategoryIds(); returns an array of category IDs associated with the product
      foreach ($product->getCategoryIds() as $category_id)
      {
          $category = Mage::getModel('catalog/category')->load($category_id);
          $prod_collection_1['parent_category'] = $category->getParentCategory()->getName();
          $prod_collection_1['category'] = $category->getName();
          //$prod_collection_1['category_idx'] = preg_replace('/[\s\'\"]/i', '_', strtolower(trim($prod_collection_1['category'])));
          $prod_collection_1['category_id'] = $category->getId();
      }

      #/gets the image url of the product
      $prod_collection_1['img'] = Mage::getBaseUrl(Mage_Core_Model_Store::URL_TYPE_MEDIA).'catalog/product'.$product->getImage();


      $prod_collection[] = $prod_collection_1;

    }//end foreach.....

    $prod_whole[$cat_id] = $prod_collection;

}//end foreach categories.......
//var_dump('<pre>', $prod_whole);

希望这会有所帮助。

<?php

    $category_id = 10; // if you know static category then enter number

$catagory_model = Mage::getModel('catalog/category')->load($category_id); //where $category_id is the id of the category



     $collection = Mage::getResourceModel('catalog/product_collection');

        $collection->addCategoryFilter($catagory_model); //category filter

        $collection->addAttributeToFilter('status',1); //only enabled product

        $collection->addAttributeToSelect(array('name','url','small_image')); //add product attribute to be fetched

        //$collection->getSelect()->order('rand()'); //uncomment to get products in random order    

        $collection->addStoreFilter();          

        if(!empty($collection))

        {

                foreach ($collection as $_product):

                echo $_product->getName();   //get product name        

            endforeach;

        }else

            {

                echo 'No products exists';

        }              

    ?>

您应该始终避免将这样的代码放入视图中，这是非常糟糕的做法。 您也可能会遇到问题，因为可以缓存视图，从而导致意外行为。

你应该覆盖你正在使用的块，在那里放置代码。然后，您可以在视图文件中调用任何新方法。

例如，您可以复制 Mage_Catalog_Block_Product_List

来自：app/code/core/Catalog/Block/Product/List.php

到：app/code/local/Catalog/Block/Product/List.php

然后您可以添加一个新方法，可能使用上述帖子中提到的一些代码。 然后，您的新方法将在您的视图文件中可用（list.phtml 或使用此块的任何视图）

这是一个将所有产品及其类别导出到 csv 的代码

<?php 
set_time_limit(0);
ini_set("memory_limit",-1);
ini_set('max_execution_time','1800000000');

require_once '../app/Mage.php';
Mage::app(); 

$category = Mage::getModel('catalog/category');
$tree = $category->getTreeModel();
$tree->load();

$ids = $tree->getCollection()->getAllIds();
$fp = fopen('category-product-export.csv', 'w');
$field = array('Product SKU','Category Name'); 
fputcsv($fp, $field);

$_productCollection = Mage::getModel('catalog/product')
                        ->getCollection()
                        ->addAttributeToSelect('*')
                        ->addFieldToFilter('visibility', Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH)
                        ->load();

foreach ($_productCollection as $_product){
   $cats = $_product->getCategoryIds();
   $cnt = 0;
   $catName = '';
    foreach($cats as $id) {
        $category->load($id);
        $root = 'Root Catalog';
            $isRoot = strtolower($root);
            $categoryName = strtolower($category->getName());
            if($categoryName == $isRoot){
                continue;
            }
        $categories[$id]['name'] = $category->getName();
        $categories[$id]['path'] = $category->getPath();

        $path = explode('/', $categories[$id]['path']);
        $len = count($path);
        $string = '';
        if($id > 2){
            foreach ($path as $k=>$pathId)
            {
                $separator = '';
                if($pathId > 2){
                    $category->load($pathId);
                    if($k != $len-1){ $separator = ' || ';}
                    $string.= $category->getName() . $separator;
                }

            }
            if($cnt > 0) {
                $catName.= ','.$string;
            } else {
                $catName = $string;
            }

            $cnt++;
        }
    }
    //echo $catName;
    $field = array($_product->getSku(),$catName); 
    fputcsv($fp, $field);   

}
