Captions

Hi @paulmyatt, assuming you’re using the display posts shortcode addon, querying image attachments, you should be able to display captions by setting the include_excerpt parameter to true:

[display-posts post_type="attachment" id="4,7,10" include_excerpt="true" bootstrap="1"]

@paulmyatt, by default the attachment description (post content) is displayed, and I guess — as your Q indicates — it might be a good idea to implement an option to display the caption (post excerpt) instead. For now, you can use the wp_bootstrap_carousel_caption_text filter hook to modify the default. Put the following in your functions.php file:

add_filter( 'wp_bootstrap_carousel_caption_text', 'myatt_wp_bootstrap_carousel_caption_text', 10, 2 );
function myatt_wp_bootstrap_carousel_caption_text( $text, $item_id )
{
    $post = get_post( $item_id );
    $excerpt = $post->post_excerpt;

    if( ! empty( $excerpt ) )
        return wpautop( wptexturize( $excerpt ) );

    return $text;
}

You’re welcome. As I said, I think it makes more sense to include the caption by default, rather than the description, because space is limited and the caption/excerpt is generally shorter than the description/content. I’ll open a ticket for this, and it should be implemented by the next release. I’ll tag you in this thread if it’s done, and after upgrading you can delete the custom function.
