Publicize: Add filter to allow plugins to bypass Publicize about jetpack

[jeherve]

Here is how one could use this new filter. In the example below, we won't publicize any post using the private tag:

/**
 * Do not trigger Publicize if the post uses the `private` tag.
 */
function jeherve_control_publicize( $should_publicize, $post ) {
    // Return early if we don't have a post yet (it hasn't been saved as a draft)
    if ( ! $post ) {
        return $should_publicize;
    }

    // Get list of tags for our post.
    $tags = wp_get_post_tags( $post->ID );

    // Loop though all tags, and return false if the tag's name is `private`
    foreach ( $tags as $tag ) {
        if ( 'private' == $tag->name ) {
            return false;
        }
    }

    return $should_publicize;
}
add_filter( 'publicize_should_publicize_published_post', 'jeherve_control_publicize', 10, 2 );

The first temporary fix would be to have the connections be non-global, which I know stops scheduled posts from publicizing.

Also, maybe have them define( 'WP_IMPORTING', true ); when it's checking -- which should stop it (I think), as well as other things like subscription notifications. Not 100% positive on that one, but I definitely agree that it's worth adding a filter to make it simpler if someone wants to disable publicizing on a category by category basis or other arbitrary data.

Good idea. I'll throw up a quick PR to get the can rolling around.

Fix tidied up in 8ed18b1

Reverted both commits.

This could have been accomplished using the existing wpas_submit_post? filter later on. It's called more times, one per service, but can just return the same value for each.

Using wpas_submit_post? filter to mark a post not to be Publicized wasn't working.

What we may want to do is add a post meta field that opts out of publicizing. This would require third-party plugins to create the post as a draft, set the meta, then publish.

Alternately, adding a filter that is checked on post creation that allows that meta to be added before it's sent onwards.

@kraftbj already responded, but for completeness: also suggested here: http://stream.boffosocko.com/2016/this-is-hopefully-a-simple-but-useful-feature-requesti-appreciate
(This also relates to jetpack_allow_per_post_subscriptions for email and alternate posting methods to WP including via email and micropub with clients like Quill

Glad to know that JetPack is on GitHub :)
