Hi Experts,

I need to validate the value of a text box.  The text box is for the customers phone number in the format 0123456789 (ie 10 numbers only)

The data is sent to a page (validate.php) via a forms POST method.

I want a function that will ONLY accept 10 numbers one after another, no letters or characters.

Thanks in advance.

Here you go:

if(!preg_match('/^\d{10}$/', $_POST['phonenumber'])) {
  //invalid
} else {
  //valid
}

-r-

or

if (!is_numeric(substr($_POST['phonenumber']), 0, 10))) {
  //invalid
} else {
  //valid
}

or

if (!is_numeric($_POST['phonenumber']) || 10 !== strlen($_POST['phonenumber'])) {
  //invalid
} else {
  //valid
}
