WordPress Display User's Avatar not Showing

Question

I am making a wordpress site now, and I just inserted an HTML block into my sidebar. I want to to serve 2 functions. 1. If the user isn't signed in, I want it to display a login block. (working) 2. If the user is signed in, I want it to display their avatar. (not working) I looked up the get_avatar function on the wordpress site, and this is what I found. But it doesn't show anything...

My code:

[logged_out][login][/logged_out]
[logged_in]
<?php
    global $current_user;
    get_currentuserinfo();
    echo get_avatar(ID, 128 );
?>
[/logged_in]

My question, is this because it is an HTML block, and it won't support PHP, or is something wrong with the code?

Answer 1

Define a shortcode in your functions.php http://codex.wordpress.org/Shortcode_API

Return <img src="avatar_src" /> from shortcode definition Then you can use that shortcode in your text widget and add this filter to make it working

add_filter('widget_text', 'do_shortcode');
