PHP Fatal error:  Uncaught Error: Call to undefined method Magento\CatalogSearch\Model\ResourceModel\Fulltext\Collection\Interceptor::getCollectionClone() in app/code/custom_theme/LayeredAjax/view/frontend/templates/layer/filter.phtml:15
Stack trace:

line 12-23

    $productCollection = $filter->getLayer()->getProductCollection();
    $productCollectionClone = $productCollection->getCollectionClone();
    $collection = $productCollectionClone
        ->removeAttributeSearch(['price.from', 'price.to']);

    $min = $collection->getMinPrice();
    $max = $collection->getMaxPrice();

    list($from, $to) = $requestValue ? explode('-', $requestValue) : [$min, $max];

I don't understand why do you want clone of your collection. But still you can try php object cloning

Instead of which is I guess not available in Magento:

$productCollection = $filter->getLayer()->getProductCollection();
$productCollectionClone = $productCollection->getCollectionClone();

Try this one:

$productCollection = $filter->getLayer()->getProductCollection();
$productCollectionClone = clone $productCollection;

  • Thanks it works! I don't know how it doesn't works with magento 2.3.3 and php 7.3 now because earlier was magento 2.2.6 and php 7.2 then all works. – Peter Oct 27 '19 at 22:12
  • @ShoaibMunir after add this solution still, I can't get my custom filter in layered navigation. Do you know solution for that? – Rohan Hapani Jan 20 at 11:09

  • codeshare.io/2ELZjO it's di.xml file code. – Rohan Hapani Jan 20 at 11:35
  • codeshare.io/aJ4rVr It's fulltext collection file of custom module. There are functions code available also. But, I didn't add here. – Rohan Hapani Jan 20 at 11:38
