我相信在remove_post_type_support 你可以做到这一点。但首先，你需要保留一个用户元，其中包含他/她可以编辑的帖子ID列表。您可以通过以下功能实现这一点-

update_user_meta( $user_id, $meta_key, $meta_value, $prev_value )

因此，无论何时加载帖子，您都可以检查他/她可编辑帖子ID的数组，并在此基础上调用或撤销帖子类型支持。查看以下代码-

// Don\'t stick with the `admin_init` hook only. If it doesn\'t work please try with other hooks also
add_action( \'admin_init\', \'codemascot_invoke_or_revoke_post_supports\' );
function codemascot_invoke_or_revoke_post_supports() {
    // By setting the last parameter from `false` to `true` you will get return an array.
    // Here I\'m using get_current_user_id() to get current logged in user ID.
    $editable_posts = get_user_meta( get_current_user_id(), $meta_key, true );
    // change the post type support based on your custom user permission
    if ( ! in_array( get_the_ID(), $editable_posts ) ) {
        remove_post_type_support( \'post\', \'editor\' );
    }
}

NB. You can store the user IDs with the permission to edit the post in post meta too. But querying a post meta has some drawbacks as post meta table usually has the higher probability of growth than user meta which may cause slow query.

上述代码块只是一个想法或概念not tested 在WordPess环境中。因此，一些重要的预防措施是-

不要坚持admin_init 仅挂钩。如果它不工作，请尝试与其他挂钩也让我知道。我会更新我的答案
