adding captions to featured image in single post

Hey williamslyd,
Can you explain more about what you would like to achieve, a caption under the featured image, or over the image like a overlay? Perhaps a mockup would help.

Best regards,
Mike

Hi,
Thank you for your patience, please try following these steps, first add a caption to your featured image in the media library:

Then add this css to your child theme stylesheet or the theme option Quick CSS:

.single-post .single-big a:after {
    content: attr(title);
}

and the caption should show like this:

Best regards,
Mike

Hi,
Thanks for the feedback, remove the css above and keep the caption in your featured image in the media library, and then try adding this code to the end of your child theme functions.php file in Appearance ▸ Editor:

function custom_post_featured_image_link( $image_link ) {
	if(is_single() && has_post_thumbnail()) {
		$image_link = get_the_post_thumbnail();
		$thumbnail_id = get_post_thumbnail_id();
		$thumbnail_caption = wp_get_attachment_caption($thumbnail_id);
		$caption_div = '<div class="featured-image-caption" style="text-align: center;">' . esc_html($thumbnail_caption) . '</div>';
		$image_link = $image_link . $caption_div;
	}
	return $image_link;
}
add_filter( 'avf_post_featured_image_link', 'custom_post_featured_image_link', 10, 3 );

the caption should show like this:

I’m not sure how it will show for your different layouts as the WordPress login above didn’t work for me so I couldn’t test, so give it a try.

Best regards,
Mike
