Hi !

I’m looking for the more efficient way to retrieve all distinct values from a custom field.

Here is my situation :
I’m using WordPress. I have a custom field named ‘agent_suburb’. It’s used with my custom post type ‘agent’. I would like to get all distinct values from this particular custom type to create a select box for my research area.

Any idea ? 🙂

Thanks for your help
