Overriding the Product Controller

Unless you want to hard-modify the original ProductController, you would need an override to assign all the necessary Supplier data to your product page.

Create a new file in override/controllers/front, and name it ProductController.php. Open it up and add some generic override code inside php tags:

class ProductController extends ProductControllerCore
{

}

We have to override the initContentMethod

class ProductController extends ProductControllerCore
{
	public function initContent()
	{
		parent::initContent();
	}
}

Make sure you call the parent at the very beginning of it, then add the following inside:

if($this->product->id_supplier)
{
	
	$id_supplier_address = Address::getAddressIdBySupplierId($this->product->id_supplier);
	$supplier_address = new Address($id_supplier_address);
}

First off, we are checking the current product has a supplier. Then, we need its address id, which we use to instantiate a new Address object that contains all of the information we seek.

At this point, we can simply assign all we want to the template:

if (Validate::isLoadedObject($supplier_address))
				{
					$this->context->smarty->assign(array(
						'supplier_country'=>  $supplier_address->country,
						'supplier_company'=>  $supplier_address->company,
						'supplier_address1'=>  $supplier_address->address1,
						'supplier_postcode'=>  $supplier_address->postcode,
						'supplier_city'=>  $supplier_address->city,
						'supplier_phone'=>  $supplier_address->phone,
						'supplier_state' => State::getNameById($supplier_address->id_state),
						'supplier_vat_number'=>  $supplier_address->vat_number,
					));
				}

As an extra measure, we make sure the loaded address object is valid and exists

When you’re done modifying the file, reach the cache/ folder and erase class_index.php

Amending the product template

Now we are ready to display our data. Open product.tpl, located in your theme’s folder. You can choose any spot, I decided to go for the area below the social links in the center column.

			{if $product->id_supplier}
				<h4><a href="{$link->getSupplierLink($product->id_supplier)}"><strong>{$product->supplier_name}</strong></a></h4>
				<ul>
					<li>{$supplier_address1}</li>
					<li>{$supplier_postcode}</li>
					<li>{$supplier_city}, {$supplier_state}</li>
					<li>{$supplier_country}</li>
					{if $supplier_vat_number}
						<li>{$supplier_vat_number}</li>
					{/if}
				</ul>

			{/if}	

I am obviously checking if this product has a supplier, otherwise those variables would not be assigned. Save and refresh, you might need to clear cache in the back office (Advanced Parameters, Performance). We’re done!
