Get product carriers on product listing

[malo6]

I want to display text next to the product photo depending on the carroers assigned to the product.
I was partially able to do this on the product page. I modified controllers/front/ProductController.php by changing:
 

            $this->context->smarty->assign(array(
                'pictures' => $pictures,
                'textFields' => $text_fields, ));

To:
 

            $this->context->smarty->assign(array(
                'pictures' => $pictures,
                'carriers' => $this->product->getCarriers(),
                'textFields' => $text_fields, ));

And then in themes/themeX/templates/catalog/product.tpl I can use following code:
 

      {if ($carriers[0]['id_carrier']==30)}
          Custom message
        {/if}

The problem is that the same code doesn't work in product-list.tpl
I will be grateful for your help.

Add in product-list.tpl this {debug} popup with available variables should appear.

I have checked and there is no carrier information there.

In the product list, how do you send that variable? Because in the example given by you, if you send only in the product controller, it will be available only in the product page. You should use a hook, available in the template.

I send only in product controller. Any tips how to do it via hook?

[Ress]

You should do a function like this, in a module:

public function hookDisplayProductPriceBlock($params)
{
	// this check is necessary because the hook is executed several times, with different parameters (unit_price, weight)
	if ($params['type'] != 'before_price') {
		return false;
	}
	
	$product = $params['product'];
	$this->context->smarty->assign(
		array(        
			'custom_product_carriers' => $product->getCarriers(),
		)
   	);

	// you will need to create this tpl and put the code for the front end in it (you will be able to use the $custom_product_carriers variable).
	return $this->display(__FILE__, 'views/templates/hook/product_carriers.tpl');
}

And of course, don't forget to register the hook.

@Ress I'm getting an error:
 

Fatal error: Uncaught Error: Call to a member function getCarriers() on array in 

Line:
 

'custom_product_carriers' => $product->getCarriers(),

 

[Ress]

public function hookDisplayProductPriceBlock($params)
{
	// this check is necessary because the hook is executed several times, with different parameters (unit_price, weight)
	if ($params['type'] != 'before_price') {
		return false;
	}
	
	$product = new Product($params['product']->id);
	$this->context->smarty->assign(
		array(        
			'custom_product_carriers' => $product->getCarriers(),
		)
   	);

	// you will need to create this tpl and put the code for the front end in it (you will be able to use the $custom_product_carriers variable).
	return $this->display(__FILE__, 'views/templates/hook/product_carriers.tpl');
}

I updated.

The error is gone, but custom_product_carriers variable is empty.
product_carriers.tpl:
 

{$custom_product_carriers|var_dump}	

Result:
 

array(0) { } 

I have checked the products and they have shipping methods assigned to them.

[Ress]

I tested the code, and it showed me okay. Check the product id, make sure you give the var_dump for the right product.

Finally got it!
Just a little change.

$product = new Product($params['product']['id_product']);

Thank you very much for your help!
