get_avatar() WP 2.5.0

Retrieve the <img> tag with the avatar of a user who is authorized or provided an email address when commenting. Most commonly used in the comments section.

Is used in the Comment Loop or the first parameter should be specified!

This function is pluggable, however, plugin authors wishing to change the output can use the get_avatar filter instead.

This is a pluggable function, and it can be replaced by a plugin. It means that this function is defined (works) only after all plugins are loaded (included), but before this moment this function has not defined. Therefore, you cannot call this and all functions depended on this function directly from a plugin code. They need to be called on plugins_loaded hook or later, for example on init hook.

Function replacement (override) — in a plugin you can create a function with the same name, then it replace this function.

#1 Show the avatar of the current commenter

<?php echo get_avatar( $comment, 32 ); ?>


<img alt='' src='http://0.gravatar.com/avatar/ad516503a11cd5ca435acc9bb6523536?s=32' class='avatar avatar-32 photo avatar-default' height='32' width='32' />

#2 Show the avatar of the current post author

<?php echo get_avatar( get_the_author_meta('user_email'), 32 ); ?>

#3 Add a style attribute to the avatar

<?php echo get_avatar( $current_user->user_email, 30, '', '', array('class'=>'pull-left', 'extra_attr'=>'style="margin: -4px 7px;"') ); ?>


<img alt="" src="http://1.gravatar.com/avatar/155e695ab2987ee3c482c1e3e690683b?s=30&d=mm&r=g" 
	class="avatar avatar-30 photo pull-left" 
	height="30" width="30" 
	style="margin: -4px 7px;"

#4 Add an additional default avatar option

The code below adds an additional Default Avatar option to the Discussion settings page. Selected avatar is saved in get_option('avatar_default') option.

# Adds a new default avatar
# The avatar file is 'def-avatar.jpg' in the theme's 'img' directory
add_filter( 'avatar_defaults', 'add_default_avatar_option' );
function add_default_avatar_option( $avatars ){
	$url = get_stylesheet_directory_uri() . '/img/def-avatar.jpg';
	$avatars[ $url ] = 'A website avatar';
	return $avatars;

In the result, we will get such option:

#5 Setup a default avatar

If in the previous example, to choose the default avatar, we need to go to the Descussion settings page and then choose a new avatar, here we can do it automatically via a hook.

The below code setups a default avatar for all avatar functions: get_avatar_url() and get_avatar_data(). But if default avatar is specified in the arguments of these functions, it will be chosen over the avatar specified by the hook (so the functions will have a higher priority).

## Setups a default avatar
## The avatar file is 'def-avatar.jpg' in the theme's 'img' directory
add_filter( 'pre_get_avatar_data', 'replace_default_avatar' );
function replace_default_avatar( $args ){
	// Discussion settings page where the default avatar can be chosen...
	// if( is_admin() && get_current_screen()->base === 'options-discussion' ) return $args;

	static $defava; if( $defava === null ) $defava = get_option( 'avatar_default', 'mystery' ); // ускоримся

	// To give the avatar functions priority over this hook. 
	// So if the developer has specified a default avatar in the functions, it won't be reset by this hook.
	if( ! $args['default'] || $defava == $args['default'] ){
		$args['default'] = get_stylesheet_directory_uri() . '/img/def-avatar.jpg';

	return $args;


Since 2.5.0 Introduced.
Since 4.2.0 Optional $args parameter added.
