In order for websites to be useful they should be easy fo their users or managers to update. Often when I’m building themes I will include an edit button in the template file using edit_post_link(). This makes me CRY a little bit (Constantly Repeating Yourself) as I would normally have the edit_post_link() function repeated across template files.

Today it occurred to me there is a better way of doing this, why not simply add a filter to ‘the_content’ and output the edit post link after the_content() is called in the templates? So this is what we have below, I’ve swapped out edit_post_link() for get_edit_post_link() which returns the url rather than echo-ing the entire hyperlink, and set a super high priority so it always appears after all the actual content and other filters have been applied: wpautop, do_shortcode etc…

function add_an_edit_link($content){
  $content .= '<p class="edit-this"><a href="' . get_edit_post_link() . '">Edit This</a></p>';
  return $content; 
add_filter('the_content',  'add_an_edit_link', 1000);

I whacked that little snippet in my functions.php file and behold, edit links appear after every occurrence of ‘the_content()’ throughout the site. Nice and DRY!
