Magento products by categories

Question

Does anyone know how I can get a list of products belonging to a specific category from within a view file in Magento?

Solution 1

You can use magento object to filter.

Example:

$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);

It all depends on which view you're in. ;-)

First off, I hope you stayed within your template set (default in my example).

Use this as an example:

<?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 ;-)
?>

I'm using the above code to display sister categories in my template - it's not ideal but it works.

It's sort of a hack because I did not yet have time to learn all the layout XML madness. Otherwise if you use the XMLs you need to keep in mind - it all depends on where you are at. Where means the template file and essentially also the layout (in terms of app/design/frontend/default/default/layout/*).

I know it's not much, but I hope it helps to get you started.

Here is the code to get products from any particular category. You can use this in view file as well.

// 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 } ?>

I pretty much needed the same. Here is how I have done it:

$prod_whole = array();
if(!empty($_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);

Hope this helps.

You can also use $currentCategory = Mage::registry('current_category');
