I have a complicated query that I need some help on,
My problem is as follows:
I need to do a query to show posts that are in both taxonomy 15 and 6 and in one of the others (139,141 or 143), my query is like so:
Array
(
[tax_query] => Array
(
[relation] => AND
[0] => Array
(
[taxonomy] => book_category
[field] => id
[terms] => Array
(
[0] => 15
[1] => 6
)
[operator] => IN
)
[1] => Array
(
[taxonomy] => book_category
[field] => id
[terms] => Array
(
[0] => 139
[0] => 141
[0] => 143
)
[operator] => IN
)
)
)
this is passed as tax_query in the WP_Query arguments
