Omschrijving

The single-product/product-image.php template in WooCommerce is a core component that handles the display of product images on single product pages. This template is primarily responsible for showcasing the main product image and any additional gallery images that the product may have. It’s a crucial part of the product detail page as it helps customers visually assess the product before making a purchase.

Key Features of single-product/product-image.php

1. Image Gallery Integration: This template includes functionality to display a main image and a series of thumbnails if the product has multiple images. This setup is typically powered by a combination of CSS for layout and JavaScript for interactive elements like sliders or lightboxes.
2. Responsive and Interactive: The image display is responsive, meaning it adjusts to fit different screen sizes and devices. It often includes zoom features or lightbox functionalities to enhance user interaction and viewability.
3. WCAG Compliance: Attention is generally given to accessibility, ensuring that image galleries are navigable with keyboard shortcuts and are screen-reader friendly, aligning with WCAG (Web Content Accessibility Guidelines).

Default Structure

In its simplest form, the product-image.php template might look something like this:

phpCode kopiërenif ( ! defined( 'ABSPATH' ) ) {
	exit; // Exit if accessed directly
}

global $post, $product;

$columns           = apply_filters( 'woocommerce_product_thumbnails_columns', 4 );
$post_thumbnail_id = $product->get_image_id();
$wrapper_classes   = apply_filters( 'woocommerce_single_product_image_gallery_classes', array(
	'woocommerce-product-gallery',
	'woocommerce-product-gallery--' . ($post_thumbnail_id ? 'with-images' : 'without-images'),
	'woocommerce-product-gallery--columns-' . absint( $columns ),
	'images',
) );
?>
<div class="<?php echo esc_attr( implode( ' ', $wrapper_classes ) ); ?>">
	<figure class="woocommerce-product-gallery__wrapper">
		<?php
		if ( $post_thumbnail_id ) {
			$html = wc_get_gallery_image_html( $post_thumbnail_id, true );
		} else {
			$html  = '<div class="woocommerce-product-gallery__image--placeholder">';
			$html .= sprintf( '<img src="%s" alt="%s" />', esc_url( wc_placeholder_img_src() ), esc_html__( 'Awaiting product image', 'woocommerce' ) );
			$html .= '</div>';
		}

		echo apply_filters( 'woocommerce_single_product_image_thumbnail_html', $html, $post_thumbnail_id );

		do_action( 'woocommerce_product_thumbnails' );
		?>
	</figure>
</div>
