Formatting phone number

dyung2 · November 2nd, 2009, 01:02 PM

Hello,

I am trying to format US phone numbers to look like this (###) ###-#### and the code that I used is:

Code:

function format_phone($phone_1)
{
	$phone = preg_replace("/[^0-9]/", "", $phone_1);

	if(strlen($phone_1) == 7)
		return preg_replace("/([0-9]{3})([0-9]{4})/", "$1-$2", $phone_1);
	elseif(strlen($phone_1) == 10)
		return preg_replace("/([0-9]{3})([0-9]{3})([0-9]{4})/", "($1) $2-$3", $phone_1);
	else
		return $phone_1;
}

This was inputted into the VirtuemartOrdersReport.php file and it does not seem to work.

have you tried a more basic approach yet? like the following:

only allow numeric input on this textbox and limit by 10 numbers in form validation:

HTML Code:

<form id="form1" name="form1" method="post" action="handler.php">
     <input id="phone" name="phone" type="text" value="" />
</form>

do the form validation and keystroke limiting something like follows in the external .js file:

Code:

document.form1.onsubmit = function () {
     if (this.value.length == 10) {  // force length of 10.
          return true;
     } else {
          alert("You need a 10 digit phone number including area code!");
          return false;
     }
}
document.formj1.phone.onkeypress = function () {
     if (!e) var e = window.event;
     if ([e.keyCode||e.which]==8||[e.keyCode||e.which]==46) // this is to allow backspace or delete.
          return true;
     if ([e.keyCode||e.which] < 48 || [e.keyCode||e.which] > 57)
          e.preventDefault? e.preventDefault() : e.returnValue = false;
}

handler.php function and usage:

PHP Code:


			
function format_phone($phone) {
    $phone = ((strlen($phone)==7)?"012":"").$phone; // insert default area code if omitted.
    $phone = "(".substr($phone_1, 0, 3).") ".substr($phone,3,3)."-".substr($phone,6,4);
    return $phone;
}
$phone = format_phone($_POST("phone"));
