contact form ending
The code below is for a contact form. It validates name, email, and messages. However when it is successfully submitted, the form disappears and a thank you message is displayed. I am not a PHP programmer. So I need some help in keeping the form on the page in addition to the thank you message. Thank you very much in advance.
From a high level:
...
<?php if($form_complete === FALSE): ?>
...
<?php else: ?><p>Thank you for your Message!</p><?php endif; ?>

<?php
// Set email variables
$email_to = 'youremail@address.com';
$email_subject = 'Form submission';
// Set required fields
$required_fields = array('fullname','email','comment');
// set error messages
$error_messages = array(
'fullname' => 'Please enter a Name to proceed.',
'email' => 'Please enter a valid Email Address to continue.',
'comment' => 'Please enter your Message to continue.'
);
// Set form status
$form_complete = FALSE;
// configure validation array
$validation = array();
// check form submittal
if(!empty($_POST)) {
// Sanitise POST array
foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value));
// Loop into required fields and make sure they match our needs
foreach($required_fields as $field) {
// the field has been submitted?
if(!array_key_exists($field, $_POST)) array_push($validation, $field);
// check there is information in the field?
if($_POST[$field] == '') array_push($validation, $field);
// validate the email address supplied
if($field == 'email') if(!validate_email_address($_POST[$field])) array_push($validation, $field);

Ray,
Thanks for the info. I got my codes from this tutorial, https://www.youtube.com/watch?v=fBfXQqDcNSk&index=22&list=PLUWoaEuQPDX5h2rbVEP4-ErVIdbNQgl_H.
I am not a PHP kind of programmer. But from the tutorial, the form seems to be straight forward. So you are saying that using regular expression for form validation in PHP is not a best practice.
