ProductController for Mass Action

Question

I am working on a mass action to 'add a category'. I have most of the peripheral things set up correctly. I added 'add a category' to the mass action dropdown and I am returning a full list of my categories in a new dropdown similar to the way the change Status mass action works. I now need to get an Action function working to append categoryids to products.

Heres my module code with the ProductController last

Renderer to use in my observer to ouput categories

 class Clr_Categorymassaction_Block_Catalog_Product_Grid_Render_Category extends Mage_Adminhtml_Block_Widget_Grid_Column_Renderer_Abstract
{
    public function render(Varien_Object $row)
    {
        $product = Mage::getModel('catalog/product')->load($row->getEntityId());
        $cats = $product->getCategoryIds();
        $allCats = '';
        foreach($cats as $key => $cat)
        {
            $_category = Mage::getModel('catalog/category')->load($cat);
            $allCats.= $_category->getName();
            if($key < count($cats)-1)
                $allCats.= ',<br />';
        }
        return $allCats;
    }

}

Building the category tree

class Clr_Categorymassaction_Model_System_Config_Source_Category
{
    public function toOptionArray($addEmpty = true)
    {
        $options = array();
        foreach ($this->load_tree() as $category) {
            $options[$category['value']] =  $category['label'];
        }

        return $options;
    }



    public function buildCategoriesMultiselectValues(Varien_Data_Tree_Node $node, $values, $level = 0)
    {
        $level++;

        $values[$node->getId()]['value'] =  $node->getId();
        $values[$node->getId()]['label'] = str_repeat("--", $level) . $node->getName();

        foreach ($node->getChildren() as $child)
        {
            $values = $this->buildCategoriesMultiselectValues($child, $values, $level);
        }

        return $values;
    }

    public function load_tree()
    {
        $store = Mage::app()->getFrontController()->getRequest()->getParam('store', 0);
        $parentId = $store ? Mage::app()->getStore($store)->getRootCategoryId() : 1;  // Current store root category

        $tree = Mage::getResourceSingleton('catalog/category_tree')->load();

        $root = $tree->getNodeById($parentId);

        if($root && $root->getId() == 1)
        {
            $root->setName(Mage::helper('catalog')->__('Root'));
        }

        $collection = Mage::getModel('catalog/category')->getCollection()
        ->setStoreId($store)
        ->addAttributeToSelect('name')
        ->addAttributeToSelect('is_active');

        $tree->addCollectionData($collection, true);

        return $this->buildCategoriesMultiselectValues($root, array());
    }
}

</config>

Just in case I need to use

class Clr_Categorymassaction_Helper_Data extends Mage_Core_Helper_Abstract
{

}

Observer

<?php

class Clr_Categorymassaction_Model_Observer {
    public function addCategoryMassAction(Varien_Event_Observer $observer)
    {
        $block = $observer ->getBlock();
        if ($block instanceof Mage_Adminhtml_Block_Catalog_Product_Grid) {
            $block->getMassactionBlock()->addItem('Clr_Categorymassaction', array(
                'label'     =>  Mage::helper('catalog')->__('Add to Category'),
                'url'       =>  $block->getUrl('*/*/massCategory', array('_current' => true)),
                'additional'=> array(
                    'visibility'    => array(
                        'name'          =>'Category',
                        'class'         =>'required-entry',
                        'label'         =>Mage::helper('catalog')->__('Categories'),
                        'type'          => 'select',
                        'values'        => Mage::getModel('Categorymassaction/system_config_source_category')->toOptionArray(),
                        'renderer'      => 'Categorymassaction/catalog_product_grid_render_category',

                        )
                    )
                ));
        };
    }


}

ProductController

class Clr_Categorymassaction_Adminhtml_Catalog_ProductController extends Mage_Adminhtml_Controller_Action
{
    public function massCategoryAction()
    {
        $category = Mage::getModel('catalog/category');
        $productIds = $this->getRequest()->getParam('product');
        $cat = $this->getRequest()->getParam('Category');
        if (!is_array($productIds)) {
            $this->_getSession()->addError($this->__('Please select product(s).'));
            $this->_redirect('*/*/index');
        }
        else {
            //convert $cat -> categoryid eg:
            //$this = $category['label']->getCategoryId();
            try {
                foreach($productIds as $product) {
                    // append categoryId to $productId
                    //$product->setCategoryIds($cat);
                    //$product->save();
                   // $cat->setPostedProducts($product);
                }
               //$cat->save();
                //Save product
                }
                catch (Exception $e){
                  $this->_getSession()->addError($e->getMessage());
                  $this->_redirect('*/*/index'); 
                }
            }

I know my controller is in a pitiful state, any direction for how I can get the productIds assigned to the $cat category would be a life saver. Thanks for digging in to the bottom.

Answer 1

Try this in your controller:

$productIds = $this->getRequest()->getParam('product');
if (!is_array($productIds)) {
    $this->_getSession()->addError($this->__('Please select product(s).'));
    $this->_redirect('*/*/index');
}

$catId = $this->getRequest()->getParam('Category');
$category = Mage::getModel('catalog/category')->load($catId);

if (!$category->getId()) {
    $this->_getSession()->addError($this->__('Category not found.'));
    $this->_redirect('*/*/index');
}

try {
    foreach($productIds as $productId) {
        $product = Mage::getModel('catalog/product')->load($productId);

        if (!$product->getId()) {
            continue;
        }

        $productCats = $product->getCategoryIds();
        $productCats = array_unique(array_merge($productCats, array($catId)));

        $product->setCategoryIds($productCats)->save();
    }
} catch (Exception $e){
    $this->_getSession()->addError($e->getMessage());
    $this->_redirect('*/*/index');
}
