Magento2 Overide \Magento\Catalog\Block\Product\View\Gallery

Question

I try to override the \Magento\Catalog\Block\Product\View\Gallery in my module.

I added the below line to my di.xml file for override above block

<preference for="Magento\Catalog\Block\Product\View\Gallery" type="Vendor\Module\Block\Product\View\GalleryXY" />

and I create the GalleryXY.php file and override methods but it does not work.

<?php 
namespace Vendor\Module\Block\Product\View;
class GalleryXY extends \Magento\Catalog\Block\Product\View\Gallery{
public function doDebugg() {
 return 'blub';
 }
 }
?>

can anyone help me on this?

Please try this

<?php 
namespace Vendor\Module\Block\Product\View;
class GalleryXY extends \Magento\Catalog\Block\Product\View\Gallery{
 public function getGalleryImages() {
 die(__METHOD__);
 }
}

• Huzur Polat: in gallery.phtml file the declation of $block i have to change or? to /app/design/frontend/Wallstyle/wsdefault/Magento_Catalog/templates/product/view/gallery.phtml /** * Product media data template * * @var $block \Magento\Catalog\Block\Product\View\Gallery */
• Huzur Polat: How can i use it now? @var $block \Vendor\Module\Block\Product\View\GalleryXY in phtml?
• gelanivishal: After override Block class, $block->getGalleryImages() this function first call from override Vendor\Module\Block\Product\View\GalleryXY class, if method is not in this class then method call from magento core class.
