带OR条件的WP_Query

Question

Here is an issue, I have a site that has sort of complex search. I have set several arguments: s, meta_query, tax_query and post_type

Obviously these are all linked with AND relationships (except meta_query and tax_query that can be set with OR relationship, but I need to get posts that have entered phrase at either title or content or some of meta values, or some of taxonomies.

Any way of doing so?

Answer 1

You should use relation parameter.

UPDATE:

Example from a page linked above:

$args = array(
    'post_type' => 'post',
    'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'movie_genre',
            'field'    => 'slug',
            'terms'    => array( 'action', 'comedy' ),
        ),
        array(
            'taxonomy' => 'actor',
            'field'    => 'term_id',
            'terms'    => array( 103, 115, 206 ),
            'operator' => 'NOT IN',
        ),
    ),
);
$query = new WP_Query( $args );
