Re: form field rejection

Try something like this (untested): $phonenumber = '(123)-123-1234'; $phonenumber = preg_replace('/[^0-9]/','',$phonenumber); if(!preg_match('/^([0-9]{3})([0-9]{3})([0-9]{4})$/',$phonenumber,$matches){ die('Invalid phone number.'); } $full_number = $matches[0]; $areacode = $matches[1]; $exchange = $matches[2]; $number = $matches[3] $banned_exchanges = array('321','654'); if(in_array($exchange,$banned_exchanges)){ die('Bad exchange.'); } Addison Ellis wrote:

hello,

    thank you for your time...
    what is the best way for me to have a form field, "phone" reject certain phone prefixes?
for example: someone enters 321-1791 and "321" prefix can not be allowed as an entry...
    thank you again, addison
