Validate phone number

With as an example for Dutch formatted phone numbers:

if(!ereg("^[0-9]{2,4}-[0-9]{6,8}$", $phone)) {
$err = $err.JText::_('RS1_INPUT_SCRN_PHONE_ERR');
}

Meaning: 2-4 numbers from 0-9 as the region code, a '-' as delimiter and 6-8 numbers from 0-9 as the phone number, for example: XX-XXXXXXXX or XXX-XXXXXXX or XXXX-XXXXXX

Addendum on my previous post:

To prevent two of the same error messages at the frontend when the telephone field is empty:

1. Edit in fe-val.php at +/- line 82:

if ($apptpro_config->requirePhone == "Yes" && $phone == "" ) {
$err = $err.JText::_('RS1_INPUT_SCRN_PHONE_ERR');

Change it to:

if ($apptpro_config->requirePhone == "Yes" && $phone == "" ) {
$err = $err.JText::_('RS1_INPUT_SCRN_PHONE_ERR_EMPTY');

2. Add a NEW token in the frontend language file at +/- line 67:

RS1_INPUT_SCRN_PHONE_ERR_EMPTY="Check your input: The field 'Telephone' is empty!<br><br>"

With this small modification you prevent getting two of the same error messages when the customer has left the telephone field empy (only valid when you've add a second check in fe-val.php as explained in the previous post.

Cheers,

UK land-line phone numbers are tricky to validate, and worse if mobile phone numbers have to be allowed. I authored this Regular Expression, for use within the UK, to avoid being too prescriptive:

^[0][1-9][ 0-9]{7,12}$

It simply checks for the leading zero of the STD code and that the next digit is from 1 to 9, then checks that the rest of the characters are either spaces or digits and the number is the right length. This approach allows for common idiosyncracies and likely future number allocations, but stops someone just entering 999 or 11111111.

It will accept:
01234 567890
01234 567 890
01234 56 78 90
012 34 56 78 90
and so on.

It rejects +44 numbers.

It's worth bearing in mind when authoring Regular Expressions that ereg (now deprecated) does not accept \d for digits or \w for whitespace characters, so you have to use [0-9] and a literal space instead.

Hi Rob
How I add validation numbers for SMS notification.
Is it possible?

Thanks

Maybe if it was automatically inserted from field "phone".

Field "sms_phone" could be hidden.

Nonsense?

Hi Rob.
Customer requests SMS notification (checkbox). Field "sms_phone" will be filled from field "phone". Field "phone" can be verified.

I'm not a programmer, so it's not perfect.
