Which Function Displays The Post Authors Gravatar

Question

I am using:

echo get_avatar(get_the_author_id(), 30);

Which works, however i am getting this notice to use:

echo get_avatar(get_the_author_meta(), 30);

Which doesn't display the authors Gravatar image, just the Gravatar default image.

**Notice:** get_the_author_ID is deprecated since version 2.8! Use get_the_author_meta('ID') instead. in C:\Users\Administrator\Desktop\www.wpsites.dev\wp-includes\functions.php on line 2908

So my question is, what should i use to display the posts author Gravatar?

Notice: get_the_author_ID is deprecated since version 2.8! Use get_the_author_meta('ID') instead. in C:\Users\Administrator\Desktop\www.wpsites.dev\wp-includes\functions.php on line 2908

You aren't using get_the_author_meta('ID'); as instructed by the Notice. You are just using get_the_author_meta(). The latter returns an empty string when I try it.

Answer 2

When looking at the source of get_avatar(), you can see that it takes either ID or email as 1st argument:

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

The source of get_the_author_meta() shows that it will return data for the following fields:

'login', 'pass', 'nicename', 'email', 'url', 'registered', 'activation_key', 'status'

As addition to @s_ha_dum answer, you can as well use email user meta data as 1st argument for get_avatar():

echo get_avatar( get_the_author_meta( 'email' ), 30 );
