Divi Post Title Module: Open Featured Image in Lightbox

Written by Dan Mossop

I've previously written about how to add a lightbox effect to Divi featured images on plain Divi posts. In this post, we look at how to make the Divi Post Title module's featured image to do the same – open a larger version of the image when clicked.

Open Divi Post Title Module Featured Image in a LIghtbox

Step 1: Add PHP Code

To make the Divi Post Title Module featured image open in a lightbox, first add the following PHP code to your site: 

add_action('wp_footer', 'dbc_open_featured_image_in_lightbox');
add_action('wp_enqueue_scripts', 'dbc_featured_image_in_lightbox_register_magnific_popup', 11); 

if (!function_exists('dbc_open_featured_image_in_lightbox')) {
	function dbc_open_featured_image_in_lightbox() {
		?>
		<script>
		jQuery(function($){
			$featured_img = $('.et_pb_post_title.featured-image-in-lightbox .et_pb_title_featured_container .et_pb_image_wrap img');
			$featured_img.wrap('<a class="et_pb_lightbox_image"></a>');
			$featured_img.each(function(){
				var img_url = $(this).attr('src');
                <?php if (apply_filters('dbc_open_featured_image_in_lightbox_use_fullsize_image', false)) { ?>
					img_url = img_url.replace(/-d+xd+(?=.(png|jpe?g|gif|bmp|webp))/i, '');
				<?php } ?>
				$(this).parent().attr('href', img_url);
			});
		});
		</script>
		<?php
	}
}
            
function dbc_featured_image_in_lightbox_register_magnific_popup() {
	if (!defined('ET_BUILDER_URI') || !defined('ET_CORE_VERSION') || version_compare(ET_CORE_VERSION, '4.10', '<')) { return; }
	wp_enqueue_style('dbc-featured-image-magnific-popup', ET_BUILDER_URI.'/feature/dynamic-assets/assets/css/magnific_popup.css', array(), ET_CORE_VERSION);
	wp_enqueue_script('dbc-featured-image-magnific-popup', ET_BUILDER_URI.'/feature/dynamic-assets/assets/js/magnific-popup.js', array( 'jquery' ), ET_CORE_VERSION, true);
}

Step 2: Add a class to the Divi Post Title module

Now, for any post title module you wish to apply the effect to, give it the "featured-image-in-lightbox" class, like so: 

Step 3: (Optional) Add a hover overlay

If you'd like to make it clearer to the user that they can click the featured image to open it in a popup, then you can add a hover overlay like this:

[dsm_before_after_image before_src="https://divibooster.com/wp-content/uploads/2023/10/image-29.png" after_src="https://divibooster.com/wp-content/uploads/2023/10/image-30.png" _builder_version="4.23" _module_preset="default" global_colors_info="{}" theme_builder_area="post_content"][/dsm_before_after_image]
You can do so by adding the following CSS code to your site:
/* === Add a hover icon to the post title module clickable featured images === */

:root {
  --post-title-module-featured-image-hover-brightness: 70%;
  --post-title-module-featured-image-hover-icon-color: white;
  --post-title-module-featured-image-hover-icon-font-size: 30pt;
}

/* Add a hover icon to the featured images in posts */
.et_pb_post_title.featured-image-in-lightbox .et_pb_title_featured_container .et_pb_image_wrap a.et_pb_lightbox_image:hover:before {
    content: "\55";
    font-family: ETmodules;
    color: var(--post-title-module-featured-image-hover-icon-color);
    font-size: var(--post-title-module-featured-image-hover-icon-font-size);
    text-shadow: 0px 0px 4px rgba(0, 0, 0, 1);
    position: absolute;
    top:50%; 
    left:50%;
    transform: translate(-50%, -50%);
    z-index: 1;
}
.et_pb_post_title.featured-image-in-lightbox .et_pb_title_featured_container .et_pb_image_wrap {
    position: relative;
}
/* Reduce the featured image brightness on hover */
.et_pb_post_title.featured-image-in-lightbox .et_pb_title_featured_container .et_pb_image_wrap a.et_pb_lightbox_image img:hover {
    filter: brightness(var(--post-title-module-featured-image-hover-brightness));
    transition: all 1s ease;
}
/* === End: Add a hover icon to the post title module clickable featured images === */
