<?php
########################
// Here you can search a post type or post and find posts
// with two different custom field data (keys).
// This is useful if you have setup two custom fields and storing
// data in the fields and need to find posts that match.
// In the case below I have two custom fields: content_client_id and content_status
// content_client_id = the id of a client
// content_status = the status of a post (EG: Awaiting Approval by Client)
// I want to find all posts that match a client id and Awaiting Approval by Client
// and then order the posts by another custom field called: content_scheduled_posting_date
