Improved @robertdall's shortcode by:

  • using WordPress coding standards
  • removing the image in the link, that seemed very specific to the Robert's use case and not general use
  • adding validation that the passed string in $content is an email address, and if not, just return out of the function, avoiding potential issues if it wasn't an email address
  • added proper output escaping to the link, for security reasons

Sorry I forgot to remove the image links when I uploaded it last night :-) That's what I get for multi-tasking and copy and pasting at the meetup…
