Having never done PHP before, I have managed to put together this basic script to handle the submittion of a form on my page:

Part of the script is to check whenther the email address is valid or not, if it is not valid, it alerts the user via a javascript alert box, however after doing so, the pages directs to the php script displaying a blank page - e.g. www.*domain*.co.uk/submit.php :( I dont want this to happen, I want it to stay on the original form page: www.*domain*.co.uk/enquiry.html.

I would also like, when the script displays the email is invalid, to clear the email input box on the page. Does anyone have any idea how I do this?


PHP
Code: 
<?php
/* Set e-mail recipient */
$myemail  = "enquiries@*domain*.co.uk";

/* Check all form inputs using check_input function */
$regarding    = check_input($_POST['regarding']);
$firstname = check_input($_POST['firstname'], "Enter your first name");
$lastname = check_input($_POST['lastname'], "Enter your last name");
$companyname    = check_input($_POST['companyname']);
$address1  = check_input($_POST['address1']);
$address2  = check_input($_POST['address2']);
$city   = check_input($_POST['city']);
$region = check_input($_POST['region']);
$postcode   = check_input($_POST['postcode']);
$country = check_input($_POST['country']);
$email   = check_input($_POST['email']);
$number = check_input($_POST['number']);
$enquiry = check_input($_POST['enquiry']);

/* If e-mail is not valid show error message */
if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/", $email))
{

	show_error("The E-mail address entered is not valid.");
	

}

$subject = "New $regarding Enquiry";

/* Let's prepare the message for the e-mail */
$message = "A enquiry form has been submitted:

Enquiry regarding $regarding

Name: $firstname $lastname

Company: $companyname

Address: 
$address1
$address2
$city
$region
$postcode
$country

E-mail: $email
Contact Number: $number

Enquiry:
$enquiry

";

$headers = "From: enquiryform@*domain*.co.uk";



/* Send the message using mail() function */
mail($myemail, $subject, $message, $headers);

/* Redirect visitor to the thank you page */
header('Location: thanks.html');
exit();

/* Functions we used */
function check_input($data, $problem='')
{
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    if ($problem && strlen($data) == 0)
    {
        show_error($problem);
    }
    return $data;
}

function show_error($myError)
{
	echo "<script language=\"javascript\">alert('$myError');</script>";

	exit();
}
?>

To an extent I understand! basically I have my enquiryform.html and my submit.php

the line:

require_once './_scripts/send-invite.php';

goes in the PHP yes? which should reference my submit.php?

e.g.

require_once 'submit.php';
