Problems with PostCode Inpuit Mask?

[grobermatic]

Hi,

I'm trying to figure out what the input mask should be for a post code in the United Kingdom.

I've tried severalm but my users always come up with a real post code which is not allowed by the input mask.

I've tried :

>LL<0#0>LL< - This doesn't work for Postcodes where there is only 1 letter at the start .. i.e for Liverpool where the postcodes are L#

Also some London postcodes are a bit different... WC1 N1AF

Any ideas for a versatile Input Mask which would accommodate all these possiblilties as well as the normal 2 letters 1 number, 1 number 2 letters

Any help would be appreciated

You could have an input mask table. That is a table with a few different input masks stored. This table could be associated with different towns, suburbs. As the users selects the known suburb a known mask is used. If the user selects a new suburb they could be offered a choice of masks to apply. There is a bit of work here to make this user friendly, but it could be done.

Hi, did you ever find a solution to this? Apart from the table suggestion, which is not appropriate for clients who want a simple interface!

Thanks

You don't have to show your client a complex user interface. With a bit of imagination you can mask it and deal with the complexity in your code.

Hi,

With some experimentation, I found that :

LA&&&&C??

works for all postcodes I have come across.

Thanks anyway
