In this function-

 public function getResults()
    $results = [];
    foreach ($this->getLoadedProductCollection() as $product) {
        $data['img'] = $this->encodeMediaUrl(
            $this->getImage($product, 'amasty_xsearch_page_list')- 
        $data['url'] = $product->getProductUrl();
        $data['name'] = $this->getName($product);
        $data['description'] = $this->getDescription($product);
        $data['sku'] = $this->getSku($product);
        $data['price'] = $this->getProductPrice($product);
        $data['is_salable'] = $product->isSaleable();
        $data['product_data'] = [
            'entity_id' => (string)$product->getId(),
            'request_path' => (string)$product->getRequestPath()
        $data['reviews'] = $this->getReviewsSummaryHtml($product, 
        $results[$product->getId()] = $data;

    return $results;

I added this line-

$data['sku'] = $this->getSku($product);

I then created this function-

public function getSku(\Magento\Catalog\Model\Product $product)
    return $this->getResults()->get($sku);

On the page I am trying to display it on I have this code-

 <?= $product['sku'] ?>

The extension pulls the name and description so I tried to just copy what was done for those attributes but it doesn't seem to work.

  • your getSku function should recieved a $sku variable public function getSku($sku) { return $this->getResults()->get($sku); } – fmsthird Apr 18 '19 at 21:14

Seems as it infinity call stack, can you edit your added line to

$data['sku'] = $product->getSku();

or edit your function to

public function getSku(\Magento\Catalog\Model\Product $product)
   return $product->getSku();
  • I changed the function and that worked great, but I don't understand why. Could you explain a little if you get a chance? If not I really appreciate the help. – Tyler Jensen Apr 18 '19 at 21:59
  • @TylerJensen inner function getResult you call getSku then inside getSku call getResult, it is a infinity stack trace. – Petro Chaikivskyi Apr 19 '19 at 4:35
  • That makes sense thanks you. – Tyler Jensen Apr 19 '19 at 13:31
