How to set gravatar picture programmatically?

Question

I'm using gravatar to display my user contact in WordPress but I want to allow them to change their picture. I don't see any way to set it with the API.

I'm not using Woocommerce and I already know to fetch the avatar. Is it possible?

Edit

After some search, I found in the api documentation, this section : https://fr.gravatar.com/site/implement/xmlrpc/

But I still don't understand how to implement it with my WordPress avatar.

Answer 1

You can simply use plugin https://wordpress.org/plugins/wp-user-avatar/ and use their shortcode wherever you want to show the upload picture form just install the plugin and

use

echo do_shortcode('[avatar_upload]');

It will show the form to upload the picture

Answer 2

I think that gravatar not have api to let you update it from external site but maybe there is other solutions to feet your needs.

You can do the following: let the user add a profile picture directly in your site using a plugin or by developing your own solution, then check if user has defined his avatar and print it, if not print gravatar or nothing.

There is a lot of plugin to manage avatar, check for example this:

• https://it.wordpress.org/plugins/wp-user-avatar/

For what about the custom development you can use for example a form builder like formidable form to let the user upload some image: Here an example of workflow:

• create a form with file upload with only image format accepted https://formidableforms.com/knowledgebase/file-upload/
• set create post (better if you use custom post type) as form action https://formidableforms.com/knowledgebase/create-posts/
• store the post id in usermeta add_user_meta( $user_id, 'avatar_id', $theAvatarId);
• use get_avatar filter to check if there is an avatar stored in usermeta and change the output from gravatar to custom https://codex.wordpress.org/Plugin_API/Filter_Reference/get_avatar
