Thanks for an interesting question. The safest way to get the ID list is to write a small function of your own, make it a shortcode and then use the [mla_gallery] mla_alt_shortcode parameter to compose the list you want and capture the ID values. Here is some code you can adapt to your application:
function capture_ids_values( $attr ) {
global $ids;
$ids = $attr['ids'];
}
add_shortcode( 'capture_ids', 'capture_ids_values' );
function get_mla_gallery_ids() {
global $ids;
do_shortcode( '[mla_gallery attachment_category="my category" mla_alt_shortcode="capture_ids"]' );
return $ids;
}
There are many ways to improve and expand on this code, but it illustrates the basic technique.
I am marking this topic resolved, but please update it if you have any problems or further questions regarding the above suggestions. Thanks for your interest in the plugin.
