Default thumbnail

Thank you for using MediaPress. It’s very easy to accomplish without modifying core.

We can use the filter “mpp_get_gallery_default_cover_image_src”

I have a question before I can assist you further. Do you want it based on logged in user id or do you want it to be based on gallery’s owner id?

Thank you

Thank you for your quick response.

I want it based on gallery’s owner id

Thank you. You may use the following code

/**
 * Custom default MediaPress gallery cover based on member type.
 *
 * @param string      $cover_src cover image url.
 * @param string      $type gallery type(photo, audio, video, doc etc)
 * @param MPP_Gallery $gallery Gallery object.
 *
 * @return string
 */
function mpp_custom_gallery_cover( $cover_src, $type, $gallery ) {
	$gallery  = mpp_get_gallery( $gallery );
	$owner_id = $gallery->user_id; // user_id will work in cases(groups, user's sitewide).

	$member_type = bp_get_member_type( $owner_id, true );

	switch ( $member_type ) {

		case 'doctor':
			$cover_src = "https://example.com/somee_image.png";
			break;
		case 'nurse':
			$cover_src = "https://example.com/some_other_image.png";
			break;

		default:
			// this is the fallback cover if you want to modify it too.
			$cover_src = "https://example.com/patients.png";
			break;

	}

	return $cover_src;
}

add_filter( 'mpp_get_gallery_default_cover_image_src', 'mpp_custom_gallery_cover', 10, 3 );

Please do modify the values as you need.

Thank a lot. Perfectly fine.

Although curious to know about difference between

$owner_id = $gallery->user_id;

$owner_id = mpp_get_gallery_creator_id($gallery)

Thanks a lot

You are welcome. There is no difference between these two. mpp_get_gallery_creator_id is a wrapper function and will be a better choice for future compatibility.

okay
