Back with some ideeas
I found this topic.
http://wp-types.com/forums/topic/how-to-filter-by-child-post-custom-fields-but-list-parent-posts/
Rachel said that, this is the answer.
I probably miss something.
How can I filter a parent posts list by the custom fields of the child post???
I think,
1. Insert [types field="field_name" id="$parent_post_name"][/types] into a view template;
2. Include this view template into the child view as a field.
But this will get a list of the child posts including the parent fields that belong to that child, of course,
unsortable and unfiltered by the parent and child fields together.
…or, can be fitered a view template?
…and how?
Hope this will help you to understand clearly my need.
Thanks again for your time.
