Isn’t it fun writing apps for UK :-) I have lost count of the number of times Ive had to write either phone number and postcode formatters and validators.
I have no idea about the rest of the world but here in the uk is not very straight forward. Obviously the rules are there but they are most surely esoteric. :-) I just finished a month ago writing a uk phone number formatter, that was interesting. The rules are just about as consistent as the English language itself :-) I before E expect for all the words were E is before I lol Glenn tinylion -----Original Message----- From: Daniel Harfleet [mailto:dharfl...@yahoo.com] Sent: 09 March 2012 16:05 To: jus...@classsoftware.com Cc: flex-dev@incubator.apache.org Subject: UK Postcode Hi Justin, I know you were looking at UK postcodes for a while, in respect to validation, I have noticed that there are a few very specific rules over and above just being only a letter or only a number. I am guessing this could be dealt with overriding the 'extraValidation' function. http://interim.cabinetoffice.gov.uk/govtalk/schemasstandards/e-gif/datastandards/address/postcode.aspx " * The letters Q, V and X are not used in the first position. * The letters I, J and Z are not used in the second position. * The only letters to appear in the third position are A, B, C, D, E, F, G, H, J, K, S, T, U and W. * The only letters to appear in the fourth position are A, B, E, H, M, N, P, R, V, W, X and Y. * The second half of the Postcode is always consistent numeric, alpha, alpha format and the letters C, I, K, M, O and V are never used. These conventions may change in the future if operationally required. *GIR 0AA is a Postcode that was issued historically and does not confirm to current rules on valid Postcode formats, It is however, still in use. " I think there are a few places on the web where you can find regular expressions specifically for this. hth dan
