shortcode hook to override internal links with an external one

Hi I just found a similar issue to mine that you solved.

https://www.ads-software.com/support/topic/how-to-remove-permalink-to-from-post-title-hover?replies=2

I had some custom code written from an earlier version of your plugin so that if custom field (RPW_externalurl) was filled in with an external link it would replace both thumbnail and post-title links.

<?php $exclude_ids[] = get_the_ID() ;
							$ext_url=get_post_meta(get_the_ID(), 'RPW_externalurl', true);
							$ext_url=!empty($ext_url) ? $ext_url : get_permalink();
						 ?>

Could you tell me where to insert this or similar into your functions.php?

I added the following to my child theme functions.php and it solved the issue universally with the added benefit that I did not need to alter your code!

// Add function to replace post permalink with external link if exists
add_filter('post_link','check_for_custom_url',10,3);
function check_for_custom_url( $permalink, $post, $leavename ) {
        $custom = get_post_meta(get_the_ID(), 'RPW_externalurl', true);
        return ( $custom ) ? esc_url( $custom ) : $permalink;
}

My custom field name in the aboce code is RPW_externalurl

Maybe that helps someone with the same issue.

Hi @mcnaden,
Glad you found the answer of your question. It also gives me an idea to provide a special filter inside the plugin. ??
