FTL Saturday Snippet #6

It's April 11th, and it's a Saturday. That means it's time for another quick code snippet from ForTheLose.org. Today I'll be showing you guys how to display your Gravatar in the author's post on a WordPress blog.

Firstly, today's quick snippet is credited to an article I read on WPRecipes.com when I was looking up how to do this myself a while back. So a big thanks to them.

In most cases, the commentator's Gravatar is fetched from the Gravatar servers by looking at the email the commentator used. So when you think about it, all we need to do is grab the post-author's email and tell Gravatar to display the correct image that corresponds to that email. This is accomplished very simply using the get_the_author_email() function, which fetches the email the author has in his WordPress profile.

<?php
	$author_email = get_the_author_email();
	echo get_avatar($author_email, '98');
?>

And that's it. Just paste that bad boy wherever you want the Gravatar to be displayed and you're done.

Hot damn.

Not bad, there is also a good plugin that allows your post to show with your gravatar.

So, does get_avatar() output the enclosing image tag and everything? Are there any sizing options you can use?

I decided maybe I should just look it up myself -

First, yes, it does output the enclosing image tag, so just echoing the output is the right move (its a little wierd that the function formats the image tag for you, but then you have to echo it yourself though - what good is the image url in a variable if it's already formatted?), and yes, there are more options to it - heres what the function definition looks like:

function get_avatar( $id_or_email, $size = '96', $default = '', $alt = false )

Id and email are self explanatory - size, obviously gives the (square) size, default allows you to define a default image if no gravatar is found, and alt populates the alt tag.

Interestingly, the function is in pluggable.php, which means if you wanted to use a different avatar service, or just some different logic, you could overwrite it in your theme or plugin.

One other tidbit (and then I promise I'll stop hijacking the comments) - the default get_avatar function bails if the show_avatars option is set to false - Setting this option to false is used for comment display normally, but the way you've set this code snippet up is clearly more geared toward authors.

So if you're having trouble getting it to work, make sure you've got "Use Avatars" enabled (I think its on the discussion options page).

Is that it?

I was hoping for something a little more diverse, I don't use WP.
