title: Space in Postcode
body: <p>I have a script that requires the postcode input to have a space in it, if not it will fail. Straight forward, but UK  postcodes can have gaps in different places, i.e W1 4SB, NW2 6PT or SG14 1LB how would I change users input, if there is no gap entered to the correct format using PHP?</p>
