Hi Russell,
I just added a filter to WP Tiles that makes this possible with little custom coding: every tile that links to a post gets its permalink through the filter wp_tiles_permalink
with the parameter $post_id
.
To give you an idea, you can give a single post an external link (say, post id:12 and the link to www.ads-software.com) like this:
add_filter( 'wp_tiles_permalink', 'my_theme_wp_tiles_permalink', 10, 2);
function my_theme_wp_tiles_permalink( $ret, $post_id ){
if ( !$ret && 12 === $post_id )
$ret = 'https://www.ads-software.com/';
return $ret;
}
You can of course make this more fancy using meta fields, but this is the basic idea.
Let me know if it works out!
Cheers,
Mike
