Add short code to Image caption

Hi,

I’m not sure what a ‘caption box’ is, but I’m guessing you are using some kind of a page / theme builder. You’ll have to ask them if they support including shortcodes somehow, since that’s what we are using to include buttons.

Yes, now I understand. I don’t think that’s really going to work like this easily.

I think the easier thing is to add the button in the page/post editor and position it under the image somehow.

I found one way to include the shortcode in the caption, but there is no garantuee this will work with your current theme and probably will need some additional fine-tuning. So if you’re comfortable with a code snippet, this works:

add_filter( 'img_caption_shortcode', 'mb_img_caption', 10, 3);
function mb_img_caption($empty,$attr,$content)
{
	$attr = shortcode_atts( array(
		'id'      => '',
		'align'   => 'alignnone',
		'width'   => '',
		'caption' => ''
	), $attr );

	if ( 1 > (int) $attr['width'] || empty( $attr['caption'] ) ) {
		return '';
	}

	if ( $attr['id'] ) {
		$attr['id'] = 'id="' . esc_attr( $attr['id'] ) . '" ';
	}

	return '<div ' . $attr['id']
	. 'class="wp-caption ' . esc_attr( $attr['align'] ) . '" '
	. 'style="max-width: ' . ( 10 + (int) $attr['width'] ) . 'px;">'
	. do_shortcode( $content )
	. '<p class="wp-caption-text">' . do_shortcode($attr['caption']) . '</p>'
	. '</div>';
}

This comes from the documentation here, if you want to read more about it.

Thanks. It’s my pleasure to help when I can.
