[PHP] Validating postal codes

2002-11-15 Thread DonPro 
Hi,

I'm trying to validate a Canadian postal code.  I've already written a
function; code as follows:

if(!eregi('(^[a-z][0-9][a-z][0-9][a-z][0-9]$)',$form[authpstcode])) {
   $errors[] = 'You must input a valid Canadian postal code (A9A9A9) postal
code if he/she resides in Canada';
   $continue = false;
}

The above works OK if the user enters -- M2M6N6

But fails if the user enters --- M2M 6N6  (note the space between the two
triplets)

I want my function to validate either, i.e., allow a space between the two
triplets but not enforce it.

Any idea on how to modify my test?

Thanks,
Don

This is a RTFM situation!!!

instead of just $form[autopstcode] - use str_replace(
,,$form[autopstcode])

(e.g. strip the spaces before validating the triplets)

found in 30 seconds by typing string on PHP site.

This might work:

if(!eregi('(^[a-z][0-9][a-z] ?[0-9][a-z][0-9]$)',$form[authpstcode])) {
   $errors[] = 'You must input a valid Canadian postal code (A9A9A9) postal
code if he/she resides in Canada';
   $continue = false;
}

Either you may remove spaces:
$form[authpstcode]=str_replace(' ','',$form[authpstcode])
and then compare
or change your expresion to 
'(^\s*[a-z]\s*[0-9]\s*[a-z]\s*[0-9]\s*[a-z]\s*[0-9]\s*$)'
The first is better as you may put it into database column that is just 
char(6)
