appthemes_after_post

This action hook executes in the loop-[post_type].php file and loads at the end of the_content() but before the loop endwhile runs.

appthemes_after_post();

You can use this hook to add meta data to a post, like a share link for social media sites.

<?php
function insert_share_link() { 
    echo '<div class="share-link">' . __( 'Share this link with your friends!', 'appthemes' ) . '<input type="text" value="' . esc_attr( get_permalink() ) . '">';
} 
add_action( 'appthemes_after_post', 'insert_share_link' ); 
?>
