OpenCart 3.0.2.0 - how to display SKU on category & product pages

Question

In OpenCart 3.0.2.0, I'm trying to get the category & product pages to display the "SKU" variable for each product. The variable is in the database, along with other product data, but for some ungodly reason, OpenCart doesn't have an option to display it. You can display the product name, price, stock availability, etc, but not the SKU.

Does anyone know how to do this specifically in OC 3? They've switched from PHP to Twig for the templates, and I'm not sure what I'm doing wrong but the method I was using in OC 2.0 is NOT working in 3.0.

{{ product.href }} displays the product URL
{{ product.description }} displays the description
{{ product.price }} displays the price
...but {{ product.sku }} or {{ sku }} or {{ product['sku'] }} does NOTHING.

Answer 1

Try something like in default OpenCart code. This is working fine in latest opencart version 3.0.2.0

For Category page:

Step 1: Open file catalog/controller/product/category.php

Find:

'rating'      => $result['rating'],

Add after:

'sku'         => $result['sku'],

Step 2: Open file: catalog\language\en-gb(your language)\product\category.php

Find:

$_['text_price']        = 'Price:';

Add after:

$_['text_sku']        = 'SKU:';

Step 3: Open file: catalog/view/theme/default(your theme)/template/product/category.twig

Find:

<p>{{ product.description }}</p>

Add after:

{% if product.sku %}
 <p>{{ text_sku }} {{ product.sku }}</p>
{% endif %}

For Product page:

Step 1: Open file catalog/controller/product/product.php

Find:

$data['heading_title'] = $product_info['name'];

Add after:

$data['sku'] = $product_info['sku'];

Step 2: Open file: catalog\language\en-gb(your language)\product\product.php

Find:

$_['text_model']               = 'Product Code:';

Add after:

$_['text_sku']               = 'SKU:';

Step 3: Open file: catalog/view/theme/default(your theme)/template/product/product.twig

Find:

<li>{{ text_model }} {{ model }}</li>

Add after:

{% if sku %}
<li>{{ text_sku }} {{ sku }}</li>
{% endif %}
