如何使用多个但不是全部标签共同发布

Question

How do I get posts which have at least two tags in common?

tag__in => $args shows posts which have either tag in common

tag__and => $args for post which have all tags in common

What i need is get all posts which have some tags in common, more than one tag and less than all tags in common.

Can anyone please help?

Thanks in advance!

Try using the 'tax_query' parameter in WP_Query. I haven't tried to do exactly what you're trying to do, but it should work. The tax_query parameter is an array of separate taxonomy queries, with each query specifying the taxonomy, the term_id(s) and an operator like "IN" or "NOT IN".

Look at WP_Tax_Query in wp-includes/taxonomy.php on line 534 and WP_Query::parse_tax_query in wp-includes/query.php (line 1674).

Here's an example of using tax_query with WP_Query

Hope this helps.
