How to Display Gravatar from User Email in WordPress

Gravatar has made avatars easier. Like most WordPress powered websites, we also use Gravatar in comments to show the globally recognized avatar of each comment author. Don’t know what is a gravatar? Then read: What is Gravatar? Even though most sites only use Gravatars in the comments, you can quite frankly use it anywhere you like to display any user’s profile picture. For example, in the author bio box, or in the sidebar, or in the about page. In this article, we will show you how to display Gravatar from user email in WordPress.



Note: Our example was done for a membership site. So we are grabbing the email address by pulling logged in user’s information. However, the technique of displaying gravatar from email address stays the same.

Displaying Gravatar from User Email in WordPress Template Files

First, we will show you how to display gravatar in your WordPress templates by using a simple function. Add this code in your theme’s functions.php file or in a site-specific plugin.

1	function wpbeginner_display_gravatar() {

2	global $current_user;

3	get_currentuserinfo();

4	// Get User Email Address

5	$getuseremail = $current_user->user_email;

6	// Convert email into md5 hash and set image size to 32 px

7	$usergravatar = 'http://www.gravatar.com/avatar/' . md5($getuseremail) . '?s=32';

8	echo '<img src="' . $usergravatar . '" class="wpb_gravatar" />';

}

To display gravatar in your WordPress templates use this code.

1	<?php wpbeginner_display_gravatar(); ?>

Displaying Gravatar from User Email in WordPress Posts, Pages and Widgets

Now lets assume that you do have email address of a user and permission to use their gravatar on your site. But you don’t have them as a registered user on your site. Or that you want to display the gravatars of selected users in a post, page or a widget. To solve this problem add this code in your theme’s functions.php file or in a site-specific plugin:

01	function wpb_display_gravatar($atts) {

02	extract( shortcode_atts( array(

03	'wpb_user_email' => '',

04	), $atts ) );

05	if ($wpb_user_email == '') {

06	global $current_user;

07	get_currentuserinfo();

08	$getuseremail = $current_user->user_email;

09

} else {

10	$getuseremail = $wpb_user_email;

11

}

12	$usergravatar = 'http://www.gravatar.com/avatar/' . md5($getuseremail) . '?s=32';

13

14	echo '<img src="' . $usergravatar . '" />';

15

}

16

17	add_shortcode('wpb_gravatar', 'wpb_display_gravatar');

What we have done in the above code is that we modified the original wpbeginner_display_avatar function and created a shortcode. This shortcode wpb_gravatar accepts one paramater wpb_user_email. If you have specified an email address parameter in your shortcode, then it displays gravatar for the email address provided in the shortcode instead of the current user. This shortcode can be used in posts, pages, and widgets. To display the gravatar of the current user use this shortcode:

[wpb_gravatar]

To display the gravatar of a user email address use shortcode like this:

[wpb_gravatar wpb_user_email="john.smith@example.com"]

You can also add CSS by adding .wpb_gravatar class to your stylesheet. Like this:

1	.wpb_gravatar {

2	padding: 3px;

3	margin: 3px;

4	background:#FFFFFF;

5	border:2px solid #eee;

}
