Get specific meta data of an image via shortcode

Hi,

Please add this code to your child theme:

function avia_display_image_copyright( $atts ) 
{
	$atts = shortcode_atts(array('id' => ''), $atts);
	$copyright_text = '';

	if(!empty($atts['id']))
	{
		$copyright_text = get_post_meta($atts['id'], '_avia_attachment_copyright', true );
	}
	else
	{
      if(has_post_thumbnail())
      {
        $post_thumbnail_id = get_post_thumbnail_id();
        $copyright_text = get_post_meta($post_thumbnail_id, '_avia_attachment_copyright', true );
      }
	}

	return $copyright_text;
}
add_shortcode( 'av_display_image_copyright', 'avia_display_image_copyright' );

You can then use this shortcode:

[av_display_image_copyright]

to display the copyright information of the featured image. If you want to display the copyright information of another image (which is not the featured image) you can use this code:

[av_display_image_copyright id=852]

and replace 852 with the (attachment) id of the image.

Best regards,
Peter

Hi,

Sure – you can replace i.e. the line:

return $copyright_text;

with

if(!empty($copyright_text)) $copyright_text = '<div class="avia_image_copyright">'.$copyright_text.'</div>';
return $copyright_text;

and then use the avia_image_copyright class to style the copyright text.

Best regards,
Peter
