Greetings everyone,
here is my short guide to solving a common problem with the lack of support for outputting html content in product custom attributes.

Advantages of my approach are:
- No headache
- No plugins

So all we need is just a single file that located /catalog/model/catalog/product.php. Find this code around line 319:

Code: Select all

			foreach ($product_attribute_query->rows as $product_attribute) {
				$product_attribute_data[] = array(
					'attribute_id' => $product_attribute['attribute_id'],
					'name'         => $product_attribute['name'],
					 'text'         => $product_attribute['text']
				);
			}
and replace last key => value like this:

Code: Select all

'text'         => html_entity_decode($product_attribute['text'], ENT_QUOTES, 'UTF-8')
Voila. Now you able to put your HTML in custom product attribute field from admin area and get correct output that you can easily beautify via css ;)

/catalog/model/catalog/products.php
Except that this PHP file does not exist from the controller or model folders originally. The singular filename does.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.

um, I accidentally made a typo and already fixed it. soz.

incorrect path is
/catalog/model/catalog/products.php
and correct path is almost the same as above, but without "s" in filename :)
/catalog/model/catalog/product.php

Beside the fact that what you are posting is not understandable, why should someone use a twig editor when you have to edit a php file?

I was asking if you could edit the twig file to enter "Adding HTML to the Product Attributes OC 3.x," instead of the php file., and if so where ? (using the twig editor I thought was a easier way just from within admin area)
if Not ....does it have to be in the php file.

1. do still not know what do you understand as "twig editor" .. ?
Guess you mean the template editor in the backend.

2. whenever possible try to avoid to edit template files (as of OpenCart 3.x the template engine is twig, therefore these files end with .twig)
What if you change once the template?
Therefore the solution above is the correct one.
(beside this, editing the code inside the .twig file will cost you much more effort - but can be done).
