Q: How can I override the cover image of my products?
A: By default, when a product is displayed in a list its cover image is used, it is configurable in the BackOffice and is set in product properties via the cover_image_id key.
If you want to change this default behaviour you can use the actionGetProductPropertiesAfter in your module and change this key.
<?php
/**
* Here is an example where we use the first combination image instead of the default cover image,
* this is useful when you want to display an image matching your current research for example.
*/
public function hookActionGetProductPropertiesAfter($params) {
$product = $params['product'];
$productInstance = new Product($product['id_product']);
$productAttributeId = $product['id_product_attribute'];
$combinationImages = $productInstance->getCombinationImages($params['id_lang']);
if (empty($combinationImages) || empty($combinationImages[$productAttributeId])) {
return;
}
// Update cover image ID to use the first image of the product combination
$attributesImages = $combinationImages[$productAttributeId];
if (isset($attributesImages[0]['id_image'])) {
$params['product']['cover_image_id'] = $attributesImages[0]['id_image'];
}
}
