appthemes_after_post_content

This action hook executes in the loop-[post_type].php file and loads right after the_content() is run.

appthemes_after_post_content();

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_content', 'insert_share_link' ); 
?>
