Magento 1.9 - To get all simple(associated) products of grouped product regardless of websites/store views

Question

I'm operating multiple websites(storeviews) and i want to bring all simple products on A website although it doesn't be checked to appear on A website on product-website tab.

There would be only grouped products on A website and then click them, i want to show all of simple products associated with the grouped product even they are not a member of A website.

Literally, I'd like to implement what shows in Magento Admin Page on A website catalog page.

So, I want to modify grouped.phtml file and it needs that a product(grouped product) that this module calls have to call all of associated simple product regardless of checking this website or not. Is there a way to implement this ? Please share your opinion.

app/design/frontend/base/default/template/catalog/product/view/type/Grouped.phtml

<?php $this->setPreconfiguredValue(); ?>
<?php $_product = $this->getProduct(); ?>
<?php $_associatedProducts = $this->getAssociatedProducts(); ?>
<?php $_hasAssociatedProducts = count($_associatedProducts) > 0; ?>
<?php if ($this->displayProductStockStatus()): ?>
<?php if ($_product->isAvailable() && $_hasAssociatedProducts): ?>
    <p class="availability in-stock"><?php echo $this->__('Availability:') ?> <span><?php echo $this->__('In stock') ?></span></p>
<?php else: ?>
    <p class="availability out-of-stock"><?php echo $this->__('Availability:') ?> <span><?php echo $this->__('Out of stock') ?></span></p>
<?php endif; ?>

Answer 1

Method 1

If you take a look at Mage_Catalog_Block_Product_View_Abstract::getProduct (/app/code/core/Mage/Catalog/Block/Product/View/Abstract.php) you can see that the block retrieves the product with a store filter applied to it.

You will need to create a custom module that overrides this function, calling the product without the store filter.

Take a look at http://inchoo.net/magento/overriding-magento-blocks-models-helpers-and-controllers/ for information regarding how to override blocks (and other classes).

To get you started /app/code/local/MyModule/Grouped/etc/config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <MyModule_Grouped>
            <version>0.1.0</version>
        </MyModule_Grouped>
    </modules>
    <global>
        <blocks>
            <catalog>
                <rewrite>
                    <product_view_type_grouped>MyModule_Grouped_Block_Rewrite_Product_View_Type_Grouped</product_view_type_grouped>
                </rewrite>
            </catalog>
        </blocks>
    </global>
</config>

/app/code/local/MyModule/Grouped/Block/Rewrite/Product/View/Type/Grouped.php

class MyModule_Grouped_Block_Rewrite_Product_View_Type_Grouped extends Mage_Catalog_Block_Product_View_Type_Grouped
{
    /**
     * Revert getProduct functionality to parent:parent
     * 
     * @see Mage_Catalog_Block_Product_Abstract
     * @return null|Mage_Catalog_Model_Product
     */
    public function getProduct()
    {
        if (!$this->hasData('product')) {
            $this->setData('product', Mage::registry('product'));
        }

        return $this->getData('product');
    }
}

You'll need to flesh out the module a little more, but hopefully that helps. The block override essentially calls the parent class' parent method (reverting to the default getProduct functionality)

This is untested!

A better way of doing this would be to create your own module that does exactly what you want without overwriting anything!

Method 2

Instead of overriding the functionality in the block class you could create a new block that extends Mage_Catalog_Block_Product_Abstract rather than Mage_Catalog_Block_Product_View_Abstract and simply leave the class empty. As you've extended from Mage_Catalog_Block_Product_Abstract the getProduct functionality will not assign a store to a product.

Then update the PRODUCT_TYPE_configurable node block in your themes layout XML to use your new block that doesn't use any of the store assigning functionality. Eg: mymodule/my_new_grouped_block

<PRODUCT_TYPE_grouped translate="label" module="catalog">
    <label>Catalog Product View (Grouped)</label>
    <reference name="product.info">
        <block type="mymodule/my_new_grouped_block" name="product.info.grouped" as="product_type_data" template="catalog/product/view/type/grouped.phtml">
            <block type="core/text_list" name="product.info.grouped.extra" as="product_type_data_extra" translate="label">
                <label>Product Extra Info</label>
            </block>
        </block>
    </reference>
</PRODUCT_TYPE_grouped>
