Add MPN, EAN and weight to products page

I want to add more info to products page like the MPN code, the weight of products etc, is that possible?

What's the abbreviation (like {{ text_manufacturer }} ) for MPN, EAN and weight?

Thank in advance!

In catalog/controller/product/product.php file,

find:
add below:
In catalog/language/your_language_code/product/product.php file,

add at the bottom:
In your catalog/view/theme/<your_theme>/template/product/product.twig file, add:
where you want.

Then, ensure to apply these steps: viewtopic.php?f=176&p=725084#p718325

This should resolved the issue.

Much appreciated, thank for your time!

Works as charm! Thanks a lot, you saved me as well!!

Hi
Thanks for the post as this is an issue I am looking at and cannot resolve. Here is the code that I am applying in the different files in context:

$data['product_id'] = (int)$this->request->get['product_id'];
$data['manufacturer'] = $product_info['manufacturer'];
$data['manufacturers'] = $this->url->link('product/manufacturer/info', 'manufacturer_id=' . $product_info['manufacturer_id']);
$data['model'] = $product_info['model'];
$data['reward'] = $product_info['reward'];
$data['points'] = $product_info['points'];
$data['mpn'] = html_entity_decode($product_info['mpn'], ENT_QUOTES, 'UTF-8');
$data['ean'] = html_entity_decode($product_info['ean'], ENT_QUOTES, 'UTF-8');
$data['description'] = html_entity_decode($product_info['description'], ENT_QUOTES,


$_['text_week'] = 'week';
$_['text_semi_month'] = 'half-month';
$_['text_month'] = 'month';
$_['text_year'] = 'year';
$_['text_mpn'] = 'MPN:';


{% if additionalfields %}
{% for key, additionalfield in additionalfields %}
<li id="customfield-{{ key }}">
<span class="text-bold">{{ additionalfield.title }}:</span>&nbsp;{{ additionalfield.text }}
</li>
{% endfor %}
{% endif %}

{% if mpn %}
{{ text_mpn}} {{ mpn }}
{% endif %}

{% if ean %}
{{text_ean}} {{ ean }}
{% endif %}

<li><span class="text-bold">{{ text_stock }}</span>&nbsp;<span class="{{ stock_color }}-text text-darken-1 text-bold">{{
stock }}</span></li>
{% if type_remainder == 'numerical' %}
<li><span class="text-bold">{{ text_remainder }}</span>:&nbsp;{{ remainder }}</li>
{% endif %}
I have done all the refreshes on Mods/Dashboard and even clear vqmod caches but nothing seems to work. Can you advise? Opencart 3.0.2.0. Thanks for your attention.
The result in product page is:

I don't see any relations between this topic request and the use of your: additionalfields array. You are setting the MPN, EAN and weight while conditioning the additionalfields array but not when it's excluded, according to your posted codes above.

Thanks for taking the time to reply.
I am trying to get the mpn etc to appear on product page as this thread suggests. I have followed your instructions. The additional fields are not my construction they were there as part of the theme I am using. I simply added the code as described in the thread.

If you were adding the code as described on the above's instructions, it wouldn't be between the additionalfields variable. It has to be outside of the condition.
