Add to cart custom template

Question

I want to know how to add the link to add the product to the card.

I get all my product from magento, but I only display "add to card" but without link.

On my template, I display several products, but internet links that I've found show only how to add url to one product, if I'm right (such as : Magento 2: How to get add to cart url in custom templete file and add product to cart)

EDIT : i'm using magento 2.2.4. I'm using a custom template and I want to add the button inside a table of product, in the last of a

This is my block :

    public function getProductsCollection(){
        $objectManager =  \Magento\Framework\App\ObjectManager::getInstance();

            $appState = $objectManager->get('\Magento\Framework\App\State');
    //        $appState->setAreaCode('frontend');

            $productCollectionFactory = $objectManager->get('\Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
            $collection = $productCollectionFactory->create();
            $collection->addAttributeToSelect('*');
            //$collection->setPageSize(3); // selecting only 3 products
            $productListe = array();
            foreach ($collection as $product) {
                $productListe[] = $product->getData();
            }
            return $productListe;
        }

public function getProductCollection()
    {
        /** @var $collection \Magento\Catalog\Model\ResourceModel\Product\Collection */
        $collection = $this->_productCollectionFactory->create()->addAttributeToSelect('*')->load();

        return $collection;
    }
    public function getAddToCartPostParams($product)
    {
        return $this->listProductBlock->getAddToCartPostParams($product);
    }

And my view :

$cadencier = $this->getClientCadencier($customerCode);
//$listProducts = $this->getProductsCollection();

$_productCollection = $this->getProductCollection();

foreach($cadencier as $article){
                ...
        ?>
            <tr class="ligne">

I'm getting some info of a webservice. When I get the infos, I have an error of type ($cadencier contains array) and I can't go to the page (because of the exception).

When I'm using getProductCollection(), I can add to cart but my function for my webservice isn't working with getProductCollection. When I try to display the returned value of getProductCollection, I have an Out of memory error.

Answer 1

There are several things in your code which I see may need to improve :).

First, Magento encourage to use dependence injection, so using Object manager is not best practice.

Secondly, you can follow this link to get product collection and loop through it so that you will have multiple product instead of one.

https://www.mageplaza.com/how-get-product-collection-magento-2.html

Third thing is, if you check that file magento/module-catalog/Block/Product/AbstractProduct.php I believed it should has a function like getAddToCartUrl($product) (2.1.9) so you can use that also in the loop to get right url.

Hope that help :), feel free to reach me if you need something more about that.
