WordPress hack: Automatically insert author bio on each post

October 26, 2009 at 9:24 am

Using WordPress hooks, it can be very easy to modify WordPress variables to fit your needs. In this recipe, I’m going to show you how to use hooks to automatically insert the author bio after each post.

Open your functions.php file and paste the following code. That’s all you have to do!

function get_author_bio ($content=''){
    global $post;

    $html="<div class='clearfix' id='about_author'>\n";
    $html.="<img width='80' height='80' class='avatar' src='http://www.gravatar.com/avatar.php?gravatar_id=".md5(get_the_author_email()). "&default=".urlencode($GLOBALS['defaultgravatar'])."&size=80&r=PG' alt='PG'/>\n";
    $html.="<div class='author_text'>\n";
    $html.="<h4>Author: <span>".$post_author_name."</span></h4>\n";
    $html.= $post_author_description."\n";
    $html.="<div class='clear'></div>\n";
    $content .= $html;
    return $content;

add_filter('the_content', 'get_author_bio');

Thanks to Lam Nguyen for this cool little trick!
