I have custom-post-type company and taxonomy services for this CPT. I have created meta-field service_[id]_price for companies and fill this field with a number. If this company has not price for this service, I fill 0 in this field.

On the services page, I need a list of companies sorted by current service price ASC. In this case, I first get all companies with "0" value in this field. But I need to get all companies where this field has not zero value in ASC order - first, and all that have value '0' at the end.

  • consider not saving anything under the key if there is no price, rather than zero. you can query for posts both where a meta key does and does not exist, and have the posts where it does exist appear first. – Milo Jan 27 '16 at 19:43

You can use a meta_query in your WP_Query

$args = array(
    'post_type'  => 'company',
    'meta_query' => array(
        array(
            'key' => 'service_XXXX_price',
            'value' => '0',
            'compare' => '!=',
        ),
    ),
);
$company_query = new WP_Query( $args );

You can find more infos about the meta querys in the codex: https://codex.wordpress.org/Class_Reference/WP_Query

  • In this case I just exclude services with price = 0. But I need to get all companies and sort it: Part-1: with service price > 0 in ASC order, Part-2: with service price = 0 – Artur Jan 27 '16 at 20:00
  • I think I need to JOIN two queries here... – Artur Jan 27 '16 at 20:15
  • You can use an if-statement. If the value is 0, then copy it in an array, else echo the post. At the end you can echo the posts from the 0-array – Sören Wrede Jan 27 '16 at 22:33
