Hi Camilo,
I got it. So if you use the helper function rwmb_meta
to get the value, you can use a filter to remove the extra zeros. This is the filter:
apply_filters( 'rwmb_meta', $meta, $key, $args, $post_id );
So you can do something like this:
add_filter( 'rwmb_meta', function( $meta, $key, $args, $post_id ) {
if ( 'your_field_id' === $key ) {
$meta = your_function_remove_extra_zeros( $meta );
}
return $meta;
}, 10, 4 );
