Request: Allow Gravatar's "d" param to be filtered

[henry.wright]

Inside get_avatar_data() the d param is set like this:

$url_args = array(
    's' => $args['size'],
    'd' => $args['default'],
    'f' => $args['force_default'] ? 'y' : false,
    'r' => $args['rating'],
);

Here, $args['default'] will be something like mm or wavatar etc. These are the "default" default images generated and then served up by Gravatar. However, Gravatar also allows d to be a custom URL. Let's call this a "custom" default image.

Ref: ​https://en.gravatar.com/site/implement/images/#default-image

Is it possible to add a filter so that we can filter the value of d?

[SergeyBiryukov]

You can filter all the arguments, including $args['default'], using the ​get_avatar_data filter.

Correction: get_avatar_data probably won't work for this use case, as it runs after the URL is constructed.

​pre_get_avatar_data should work.

Thanks @SergeyBiryukov for pointing out pre_get_avatar_data. I guess d is already filterable :D

I'll close this.
