Hi George,
Happy New year 🙂

Welcome to the world of Programming. I am sure It will be an awesome experience and very helpful for your suture projects.

Also, Congratulations on creating your first plugin 🙂

About the Gallery creation, You will need to decide the following:-

component:-
members – the gallery appears on user profile on WordPress
groups- The gallery will appear on a group depending on component_id
sitewide – It is site gallery. Suitable for non BuddyPress sites.

component_id:-
– It depends on the component. It should be the user id for the ‘members’ or ‘sitewide’ and group id for the ‘groups’ gallery

type :- possible values ‘photo’, ‘video’, ‘doc’, ‘audio’ determines which type of gallery you want to create

status:- any of the available/applicable statuses. Could be ‘public’, ‘loggedin’ etc.

and then there are attributes for the title/slug etc.

If you can determine the above, you can use mpp_create_gallery() to automatically create a gallery. We do it for activity uploads.

You can see an example here.

Hi George,
You are welcome.

The API for MediaPress actions are very simple(and I have spent a lot of time making things easier to extend).

Yes, we can use the slug from the post’s slug. Should I post an example ?

Sorry about the FTP, I am sure it is back now and it was hopefully just a coincidence 🙂

I will post an example today.

Hi George,
Here is an example that creates a gallery each time a post is published

/**
 * Auto Create Custom photo gallery when new post is created.
 *
 * @param int $post_id post id.
 * @param WP_Post $post post object.
 */
function mpp_custom_create_update_associated_gallery( $post_id, $post ) {
	// Only test for already published posts.
	if ( 'publish' != $post->post_status ) {
		return;
	}

	// we only want to create gallery for 'post' post type
	// change 'post' with your own post type name.
	if ( 'post' != $post->post_type ) {
		return;
	}

	$associated_gallery_id = get_post_meta( $post_id, '_mppc_associated_photo_gallery_id', true );

	$user_id = $post->post_author;// or should we use get_current_user_id() ?
	if ( $associated_gallery_id ) {
		// wht do you want to do?
		//
		return;
	}

	// if we are here, the gallery does not exist, let us create it.

	$gallery_id = mpp_create_gallery( array(
		'creator_id'   => $user_id,
		'title'        => $post->post_title,
		'description'  => '',
		'status'       => 'public',
		'component'    => 'sitewide',
		'component_id' => $user_id,
		'type'         => 'photo',
	) );

	// save a reference to post in gallery meta?
	// and a reference of gallery to post meta?
	if ( $gallery_id ) {
		mpp_update_gallery_meta( $gallery_id, '_mppc_associated_post_id', $post_id );
		update_post_meta( $post_id, '_mppc_associated_photo_gallery_id', $gallery_id );
	}
}

add_action( 'save_post', 'mpp_custom_create_update_associated_gallery', 10, 2 );

You can update it to match for your own post type.
Hope it helps.
