I created a form parser for a WordPress site that would parse the contents of a posted form, and display a success page. I used pure php instead of trying to use a WordPress template or theme. As a downside, the displayed page would not show any WordPress theme.
So I found a solution to import the theme for the php, and this is by including the theme’s header and footer in the php file.
The complete form parser is included below:
<?php
// If title is not displayed before loading the header, WordPress displays "Page not found" as the title
echo "<head>
<title>Your form has been submitted</title>
</head>";
// Include the Main WordPress blog header
include $_SERVER['DOCUMENT_ROOT']."/wp-blog-header.php";
// Include the specific theme header you need
include $_SERVER['DOCUMENT_ROOT']."/wp-content/themes/studiopress/genesis/header.php";
// Your custom code STARTS here
// My code includes two functions.
// The first part is the background activity which parses the form, checks for errors and then mails it if there arent any errors
// The second part is html code that is displayed to the user to inform them that the form has been submitted.
if(isset($_POST['email'])) {
// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = "[email protected]";
$email_subject = "Someone has submitted feedback on your website";
function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['comments'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$comments = $_POST['comments']; // required
$error_message = "";
$email_exp = '/^[A-Za-z0-9._%-][email protected][A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
$string_exp = "/^[A-Za-z .'-]+$/";
if(!preg_match($string_exp,$first_name)) {
$error_message .= 'The First Name you entered does not appear to be valid.<br />';
}
if(!preg_match($string_exp,$last_name)) {
$error_message .= 'The Last Name you entered does not appear to be valid.<br />';
}
if(strlen($comments) < 2) {
$error_message .= 'The Comments you entered do not appear to be valid.<br />';
}
if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Form details below.\n\n";
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."\n";
$email_message .= "Last Name: ".clean_string($last_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Comments: ".clean_string($comments)."\n";
// create email headers
$headers = 'From: '.'[email protected]'."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);
?>
<?php
// Second part starts.
// This part is displayed.
echo "
<h2>
Your form has been submitted
</h2>";
echo "<h4>Dear $first_name,</h4>
<p>Your feedback has been received by us and will be forwarded to the site administrator. You will receive your login details or a response soon.</p>";
echo "<br /><br /><br /><br /><br /><br /><br />

include $_SERVER['DOCUMENT_ROOT']."/wp-content/themes/studiopress/genesis/footer.php";
?>[/code]
The following is the actual form:
You can use the following form to contact the administrator of this site:

I made it generic and detect the proper active theme:
<?php
// If title is not displayed before loading the header, WordPress displays "Page not found" as the title
echo "<head>
<title>Your feedback has been submitted</title>
</head>";
// Include the Main WordPress blog header
include $_SERVER['DOCUMENT_ROOT']."/wp-blog-header.php";
//bloginfo(‘template_url’);
$homeurl=home_url();
$ddir= get_bloginfo( 'template_directory');
$current_theme_relative_path=substr_replace($ddir, "", 0, strlen($homeurl));
//echo "<br/>The relative path to the currently active theme is ".$newss;
// Include the specific theme header you need
//echo "Full path to header is ".$_SERVER['DOCUMENT_ROOT'].$newss."/header.php";
include $_SERVER['DOCUMENT_ROOT'].$current_theme_relative_path."/header.php";
// Your custom code STARTS here
// My code includes two functions.
// The first part is the background activity which parses the form, checks for errors and then mails it if there arent any errors
// The second part is html code that is displayed to the user to inform them that the form has been submitted.
