Hi,
I have had some comeback from the developer, who has kindly provided me with the following:
“A way to access the link URL you can use this PHP function : get_post_meta( $attachment_id, ‘_gallery_link_url’, true );
So integrating that with your search results will require custom code from them but as far as access that link the above code would do it.”
I have taken a screenshot of the theme Gallery Link Settings: https://prnt.sc/1v7vtaj
Link to:
Attachment
Media File
Custom – which I have selected for external links
None
I hope this helps!
Thanks,
Sally
