Magento 2 : Overide Magento\Catalog\Block\Product\View\Gallery Block

Question

I am working on custom extension and need to override Magento\Catalog\Block\Product\View\Gallery block.

I have followed this method.

In di.xml,

<preference for="Magento\Catalog\Block\Product\View\Gallery" type="[Company]\[Vendor]\Block\Catalog\Product\View\Gallery"/>

In [Company][Vendor]\Block\Catalog\Product\View\Gallery.php

namespace [Company]\[Vendor]\Block\Catalog\Product\View;
class Gallery extends \Magento\Catalog\Block\Product\View\Gallery
{
public function getGalleryImagesJson()
 {
 $imagesItems = [];
 foreach ($this->getGalleryImages() as $image) {
 $imagesItems[] = [
 'thumb' => $image->getData('small_image_url'),
 'img' => $image->getData('medium_image_url'),
 'full' => $image->getData('large_image_url'),
 'caption' => $image->getLabel(),
 'position' => $image->getPosition(),
 'isMain' => $this->isMainImage($image),
 ];
 }
 if (empty($imagesItems)) {
 $imagesItems[] = [
 'thumb' => $this->_imageHelper->getDefaultPlaceholderUrl('thumbnail'),
 'img' => $this->_imageHelper->getDefaultPlaceholderUrl('image'),
 'full' => $this->_imageHelper->getDefaultPlaceholderUrl('image'),
 'caption' => '',
 'position' => '0',
 'isMain' => true,
 ];
 }
 return json_encode($imagesItems);
 }
}

When I do this, More Views Images of the product is don't show any more.

Can you help me into this?

Thanks in advance.

Answer 1

I found the solution. I am doing the same thing by using the plugin functionality of magento2.

For that in di.xml file specify plugin.

<type name="Magento\Catalog\Block\Product\View\Gallery">
 <plugin name="plugin_block_catalog_product_view_gallery"
 type="[Company]\[Vendor]\Block\Catalog\Product\View\Gallery"
 sortOrder="10"
 disabled="false"/>
 </type>

It is better to used.
