Wordpress functions.php modification help

I modified the [login to view URL] of my Genesis child theme and wanted to use a shortcode to link to the post. [![][1]][2] I tried something with get_permalink() but somehow it doesn't link when it is on the category page that is displayed in a modified way (see [login to view URL]). I'm looking for someone who can make the shortcode for my [login to view URL] so it shows the post links on the modified category page.
