shesgottadevelopit / validate_gravatar.php
Created Jul 14, 2016 — forked from justinph/validate_gravatar.php
In wordpress, a better way to check if an author has a gravatar or not. Sometimes you might want to check to see if a gravatar exists and not display any image if there isn't one. Uses the wordpress HTTP and caching apis. A better version of this: http://codex.wordpress.org/Using_Gravatars#Checking_for_the_Existence_of_a_Gravatar
View validate_gravatar.php
/**
* Utility function to check if a gravatar exists for a given email or id
* @param int|string|object $id_or_email A user ID, email address, or comment object
* @return bool if the gravatar exists or not
*/
function validate_gravatar($id_or_email) {
//id or email code borrowed from wp-includes/pluggable.php
$email = '';
You can’t perform that action at this time.
