Modifying K2 Gravatar AJAX Code21 Oct
I was testing the built in Gravatar support for the K2 platform today when I noticed that the URL structure was getting broken up when attempting to output the PHP code required in the comments-ajax.php file. The end result were no Gravatars showing up properly with the exception of Wordpress default avatars. I was not able to test fully, but realized there was a problem with the way K2 was linking out to retrieve the Grvatar.
After taking a look at a few code functions, I found what I believe was the problem. The gravatar code works fine under a non ALAX commenting system (meaning when you disable the dynamic commenting feature of K2) however, when enabling AJAX commenting, it failed to retrieve both the Gravatar, and the generic filler image. Simple solution as the code appeared the same was to copy the comments.php code here:
line 31
<?php /* WordPress 2.5 Avatar */ if ( function_exists('get_avatar') and get_option('show_avatars') ): ?>
<span class="gravatar">
<?php echo get_avatar( $comment, 32, get_bloginfo('template_url') . '/images/defaultgravatar.jpg' ); ?></span>
<?php /* Gravatar 2.x Plugin */ elseif ( function_exists('gravatar_image_link') ): ?>
<?php gravatar_image_link(); ?>
<?php /* Gravatar 1.x Plugin */ elseif ( function_exists('gravatar') ): ?>
<a href="http://www.gravatar.com/" title="<?php _e('What is this?','k2_domain'); ?>"><img src="<?php gravatar('X', 32, get_bloginfo('template_url') . '/images/defaultgravatar.jpg' ); ?>" class="gravatar" alt="<?php _e('Gravatar Icon','k2_domain'); ?>" /></a>
<?php /* End Gravatar Check */ endif; ?>
Copy that code into the comments-ajax.php file on line 129. This will properly sync up Gravatars that have been created by users for all comments.
