[SOLVED] phone number validation

[verN]

hiyya all,

I wanted to know how to validate the phone number entered by the user. In my database phone number is defined as int(3) unsigned. Would it be best to use php and use regular expersssions or use javascript. Any code would be beneficial

 

 

$phone = trim($_POST['phone']);

 

thanks in advance

Why do you set it as int(3)?  That means it can only hold 3 integers and a phone number is longer than that. Are you wanting to validate phone numbers internationally, US numbers, or what?

yeah i changed the phoneNo variable to varchar(10) how do i validate this to ensure onlu numbers are entered

[The14thGOD]

$phone_number = str_replace('-',"",$phone_number)

 

That might work?

is_numeric()

 

Orio.

how would i use the isNumeric value could you show the code for this

 

would it be  if(!empty){

                isNumeric(phoneNo)

                return true;

                } else {

                return false;

                error[]=You need to enter numerc values;

 

 

thanks

Use this function,

Code:

if(ereg("^[0-9]{3}-[0-9]{3}-[0-9]{4}$", $phone)) {
echo "valid phonenumber";
}
else {
echo "invalid phonenumber";
}

 

[0-9] This will check that the entered thing is number,

{3} this will check the expression for 1st 3 numbers and so on for others.
