Form Validation Help

[gajlehab]

Hello All,

My first post...

I've designed a contact form for a website that requires the entry of either a mobile number, home number or work number.

Any ideas as on what sort of coding I could use that would validate that a user has entered one of the above phone numbers?

I've played around with various if and switch statements that I found on the web but have had no luck.

Can anyone help?

Code: Select all

if ($number == null)

Wow Quick Reply!

Just to clarify I have three text fields - I just want to validate that one of the three contact numbers has been entered by the user.

Something like this:

Ye so you would need:
$number1 == null
$number2 == null
$number3 == null

etc.

Thanks but that's not working...

Does anyone know if this statement is correct:

if ((($mobile_phone ==""))(($home_phone ==""))(($work_phone ==""))){ "- You did not enter a contact number."; $error=1; }

I keep getting a parse error:

Parse error: parse error, unexpected '('

Too many (()) it only needs one, example

Code: Select all

if($variable == null)
{
exit;
}

PHP: Select all

if ( empty($mobile_phone) || empty($home_phone) || empty($work_phone) )
{
  echo "- You did not enter a contact number.";
  $error=1;
} 

That is how I would do what you are trying to do.
However I probaly would use one of the php string evaluation functions to make sure they are giveing you a real phone number.
