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.
