Variable validation - numbers only

[daveh33]

The code I am using is

 

$number = $_POST['UserMobile'];
if(ereg("^[0-9]{19}$", $number)) {
$mobile = $number;
}
else {
echo "Invalid phone number - please go back and try again<P>";
}

 

This works - but if the number is less than 19 digits it displays the "invalid phone number.." I want it so it accepts it if its up to 19 digits

 

What changes need to be made to if(ereg("^[0-9]{19}$", $number)) {

[only one]

Check the strlen() manual. and the eregi() manual

 

i think this is what you were trying too do with the code:

 

$number = $_POST['UserMobile'];
if(ereg("^[0-9]{20}$", $number)) {
$mobile = $number;
}
else {
echo "Invalid phone number - please go back and try again<P>";
}

^[0-9]{19}$

 

you can set a range within the braces from whatever to whatever

^[0-9]{1,19}$ will set a range from 1 to 19 numbers

All mobile numbers are 11 digits arn't they? and they all have to start 07

under current regulations.

The form is requesting an number in international format and is just not restricted to the UK - therefore UK numbers start 447 , but to allow  other international mobile numbers to be accepted the form needs to handle up to 19 digits.

 

^[0-9]{1,19}$ works

 

Thanks for that code
