Allowing users to edit only their page and nobody else’s

The Role Scoper plugin can enable this.

Temporary capability for current_user_can()

Yes, just filter ‘user_has_cap’. You get an array with the current capabilities that you can change without touching the database. Sample Code add_filter( ‘user_has_cap’, ‘wpse_53230_catch_cap’, 10, 3 ); /** * See WP_User::has_cap() in wp-includes/capabilities.php * * @param array $allcaps Existing capabilities for the user * @param string $caps Capabilities provided by map_meta_cap() * @param array … Read more

Allow contributor role to upload images and not edit already published articles

What do unfiltered_html and unfiltered_upload actually filter?

It is hard to come up with precise answer since capabilities are often used more broadly than they imply.

Usually it will be a difference between subject … Read more
