wp_prepare_revisions_for_js Should have more hooks/filters.

[jtsternberg]

Specifically, the array at the end should be passed through a filter then use wp_parse_args to ensure the correct parameters are correct. This would be useful for infusing more data to the models (i.e. post-meta for revisions, see this stackexchange: ​http://wordpress.stackexchange.com/questions/151630/how-to-hook-in-and-modify-the-new-revisions-ui-3-6). We still need a more WordPress way to tap into the Backbone views for the revisions UI as well.

Proposed filter

Into it.

I don't see an immediate use case for overriding the settings array. For the use case suggested (adding data to a revision model), I could see a more specific filter applied when the data's array is built.

a la

<?php
$revisions[$revision->ID] = apply_filters( 'wp_prepare_revision_for_js', array( /* revision data */ ) ); 

The filter naming is for parity with the wp_prepare_attachment_for_js filter.

Replying to ericlewis:

For the use case suggested (adding data to a revision model), I could see a more specific filter applied when the revision data's array is built.

That makes sense to me.

Filter revision array

Great suggestion!

See also some additional revisions filter ideas in #24908.

Did a little freshening and hook docs cleanup in 28627.2.diff​ - curious to hear the use case!

In 34541:

Revisions: add a 'wp_prepare_revision_for_js' filter.

Props jtsternberg, adamsilverstein.
Fixes #28627.

This hook really also needs either the revision's ID or the entire revision object passed to it as well, and probably before the parent post arg.

[DrewAPicture]

In 34831:

Docs: Document the $revision_data parameter passed to the wp_prepare_revision_for_js filter with a hash notation.

The hook was introduced in [34541].

See #28627.

In 34832:

Revisions: Also pass the $revision post object to the wp_prepare_revision_for_js filter, introduced in [34541].

Props helen.
Fixes #28627.
