solved How to get a ProductListingLazyArray ?

[R4xx4r]

Hi everybody,

I'm pretty new to PrestaShop - so sry if i ask basic things.

I'm currently working on a module which should display products (you can choose in the backend area) as additional section in the default products template - like "highly recommended products".

I finished the whole Backend part have an array with my product ID's .

As I mentioned before I wanna use the default templates which are available after a fresh installation and so I the template which is placed here: themes\classic\templates\catalog\_partials\products.tpl 

Now my big problem is: I'm not able to get the data like it should be ...

If I debug e.g. the products which are displayed in the default search behaviour, which uses exactly this template too -  I see something like

object(PrestaShop\PrestaShop\Adapter\Presenter\Product\ProductListingLazyArray)#323 (11) { ["imageRetriever":"Pr .....

So we have our product data as a ProductListingLazyArray.

I get my product data by looping over my array and make

 

 but as I get my products with 

$product = new Product($productId, true);

So of course I don't have a ProductListingLazyArray - I just have a product as an product object.

 

Do you have any idea - how I can "transform" my product object to this ProductListingLazyArray?
Or is it even the right way ?

 

THANKS for your help, ideas and recommendations!

 

Wish you a good start into the week!

Best

I just found the solution

I "faked" a search and then checked with the data i chose in the backend - here is the code:

 

/**
     * creates relevant product information for frontend output
     * 
     * @param array $allSelectedProductIds array with all id's of the selected products 
     * @param int $languageId language id of the shop you are in
     * 
     * @return array all product information we need for our frontend rendering
     */
    public function getFrontendProductInformation($allSelectedProductIds, $languageId)
    {
        // set default category Home
        $category = new Category((int)2);

        // create new product search proider
        $searchProvider = new CategoryProductSearchProvider(
            $this->context->getTranslator(),
            $category
        );

        // set actual context
        $context = new ProductSearchContext($this->context);
        
        // create new search query
        $query = new ProductSearchQuery();
        $query->setResultsPerPage(PHP_INT_MAX)->setPage(1);
        $query->setSortOrder(new SortOrder('product', 'position', 'asc'));
        
        $result = $searchProvider->runQuery(
            $context,
            $query
        );

        // Product handling - to get relevant data
        $assembler = new ProductAssembler($this->context);
        $presenterFactory = new ProductPresenterFactory($this->context);
        $presentationSettings = $presenterFactory->getPresentationSettings();
        $presenter = new ProductListingPresenter(
            new ImageRetriever(
                $this->context->link
            ),
            $this->context->link,
            new PriceFormatter(),
            new ProductColorsRetriever(),
            $this->context->getTranslator()
        );

        $products = array();
        foreach ($result->getProducts() as $rawProduct) {
            $productId = $rawProduct['id_product'];
            if(in_array($productId, $allSelectedProductIds)) {
                $product = $presenter->present(
                    $presentationSettings,
                    $assembler->assembleProduct($rawProduct),
                    $this->context->language
                );
                array_push($products, $product);
            }
        }

        return $products;
    }

 

Hope this helps somebody out there

If you have questions - just ask and I try to help

Hello, with this function is it possible to change front product display in a category ?

I've developped a module widget that display a form with selects to find some products and I managed to get the ids of the product but I don't know how to alter the product list.

Have a look at the stock ps_viewedproduct module. The function getViewedProducts() should contain the code you need to get the display data correctly, and the template in that module illustrates how to display them.

Hi,

I had been strugling on this issue too, so I made this function :
 

public static function getProductLazyArray(array $product) { $context = Context::getContext(); $presenter = new ProductPresenterFactory($context); return $presenter->getPresenter()->present( $presenter->getPresentationSettings(), $product, $context->language ); }
