Form Validation

Hi guys

I got a form and it works it send the data needed to the email address required, but I am having trouble getting the validation part of it working as needed.

Its allowing no entery for phone number, I would also like some advise to prevent people entering 00000 000000 so people have to enter what is more likely to be a real phone number.

Any help/advise on this would be great cheers.

              <?php
if(isset($_POST['email'])) {
	
	// EDIT THE 2 LINES BELOW AS REQUIRED
	$email_to = "my email here";
	$email_subject = "email subject here";
	
	
	function died($error) {
		// your error code can go here
		echo "<br /><p>We are very sorry, but there were errors found with the form you submitted. ";
		echo "These errors appear below.</p>";
		echo "<p> ".$error."</p>";
		echo "<p>Please go back and fix these errors.</p>";
		echo "<p><a href='#' onClick='history.go(-1)'><img src='img/green-arrow.png' alt='Green Back Arrow' /></a></p>";
		die();
	}
	
	// validation expected data exists
	if(!isset($_POST['name']) ||

Ah good point I did not think of but we are only UK service anyway.

 

//validate UK mobile number... - such as 07707510125
preg_match('~^([0-9]{11})$~', trim($var));

PHP:

 

Awsome I have it working so both numbers have to be valid, how would I code it to say one or the other has to be valid?

So if they put in their mainland number they dont have to put in mobile but otherwise they will have to enter mobile numer and vise versa.
