Magento 2 Custom Stock Status Custom Development

How to change the stock status on Magento 2 based on custom options#

The Task#

The task is to change the stock status on the product view page based on a seperate backend attribute.

Magento 1 code#

In the file: app/designfrontend/default/{theme}/template/catalog/product/view/type/default.phtml

The code for doing this in magento 1 is:


    $_product = $this->getProduct();
    $qty = $_product->getStockItem()->getQty();
    $qty_txt = round($qty);
    $normally_instock = $_product->getData('normally_instock');

<?php /* @var $this Mage_Catalog_Block_Product_View_Abstract */?>

    available + qty > 0:
        in stock
    available + qty < 1 + normally in stock
    available + qty < 1
    not available
        temporarily not available

<?php echo $this->getChildHtml('product_type_data_extra') ?>
<?php echo $this->getPriceHtml($_product) ?>

The solution#

First thing to do is check where in the template is the stock indicator by showing template hints.

The template is /vendor/magento/module-catalog/view/frontend/templates/product/view/type/default.phtml

and the block class is: Magento\Catalog\Block\Product\View\Type\Simple\Interceptor for simple products

But there is a snare, the template for bundle products is /var/www/shootingstuff/project/vendor/magento/module-bundle/view/frontend/templates/catalog/product/view/type/bundle.phtml and the block is Magento\Bundle\Block\Catalog\Product\View\Type\Bundle\Interceptor

The incorrect way: Overriding core template files#

So we found the string In Stock in app/code/Magento/Catalog/view/frontend/templates/product/view/type/default.phtml. So changing stuff in this file only changes simple products.

For Downloadable you have to check: Magento/Downloadable/view/frontend/templates/catalog/product/type.phtml

For Grouped products: Magento/GrouperProduct/view/frontend/templates/product/view/type/default.phtml

For Bundled products: Magento/Bundle/view/frontend/templates/catalog/product/view/type/bundle.phtml

and the summary.html file.

So it is in alot of places…


The JS option#

This is probably the best way to do it.

Correct way is using dependency injection#
