I have been trying for a couple of hours to make this work - but for some reason its simply to difficult for me. I have a custom post_type 'house', and I want to find the post_id of my custom post_type with a meta_key and certain meta value.
Lets say i want to find post_id for a house with meta_key='house_id' meta_value='231sd1223'
How exactly would i do that with wp->query?
