This code snippet is a WordPress PHP function designed to enhance the image gallery display for specific custom post types (CPTs), namely accommodations-cpt and properties-rent-cpt. The function is hooked to the WordPress wp_footer action, meaning it will execute in the footer of your site's pages. Here's a breakdown of its components and functionality:
-
Conditional Check for Post Types: At the beginning, it checks if the current page is a singular post of either the accommodations-cpt or properties-rent-cpt custom post types. This is to ensure that the scripts and styles defined within this function only apply to those specific post types.
-
Inline CSS Styling: · The CSS targets a container with a class of .showmoreimages and hides every .jet-woo-product-gallery__image-item starting from the fifth child onwards (nth-child(n+5)). · It styles the fourth image item to include an overlay indicator showing the number of additional images not displayed. This is visually represented by a FontAwesome camera icon followed by the number of hidden images. The styling includes positioning, background color, border properties, and text styling to ensure visibility and
aesthetic integration with the gallery. -
Inline JavaScript: · Once the page content is fully loaded (DOMContentLoaded event), the script queries for all elements with the .showmoreimages class, identifying them as gallery containers. · For each gallery, it calculates the number of hidden images by subtracting the number of images shown by default (4) from the total number of images in that gallery. · If there are more than four images, it sets a data-count attribute on the fourth image item with the count of additional, hidden images. This count is visually displayed thanks to the CSS applied previously.
-
Adding the Function to the wp_footer Hook: Finally, the function is added to the wp_footer action hook, ensuring it executes in the footer area of the page. This is a strategic choice because it relies on all the gallery HTML elements being loaded and accessible via JavaScript.

About the styles.css file: In summary, this CSS snippet customizes the appearance and behavior of a product image gallery in a web page. It focuses on visual enhancements like rounded corners, a grid layout with responsive adjustments, maintaining the aspect ratio of images, and adding interactive feedback on hover. This approach contributes to a more engaging and user-friendly gallery display, which is particularly useful in e-commerce settings where visual presentation can significantly impact user experience.
This customization enhances user experience by cleanly indicating when more images are available in a gallery without initially overwhelming the viewer with too many images. It also utilizes FontAwesome as a professional and visually appealing indicator.
