Displaying more information about a product’s Supplier, directly on the product page, is quite easy in PrestaShop. It only needs an override and a tiny modification to the product template.
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:
[php]
class ProductController extends ProductControllerCore
{
}
[/php]
We have to override the initContentMethod
[php]
class ProductController extends ProductControllerCore
{
public function initContent()
{
parent::initContent();
}
}
[/php]
Make sure you call the parent at the very beginning of it, then add the following inside:
[php]
if($this->product->id_supplier)
{
$id_supplier_address = Address::getAddressIdBySupplierId($this->product->id_supplier);
$supplier_address = new Address($id_supplier_address);
}
[/php]
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:
[php]
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,
));
}
[/php]
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.
[php htmlscript=”true”]
{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}
[/php]
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!
