I have three different custom fields, for day (01-07) hour (01-12) and minute (00-59) and I really need to combine them into one custom value so I can actually order them using wp_query.
I cant actually just use custom field for the whole thing; it would be easier I know, but it needs to be easy on the user to input day/time. So that option is out of the question.
Is it possible to join those three numerical values for use in wp_query?
Thanks in advance for any help.
