I'm trying to figure out how to build a contact form, but I can't understand where is the error.
Instead of sending the email, when you do push the submit button, it writes the entire php file without executing it
<?phpheader("Access-Control-Allow-Origin: *"); // Only process POST reqeusts. if ($_SERVER["REQUEST_METHOD"] == "POST") { // Get the form fields and remove whitespace. $name = strip_tags(trim($_POST["con_name"])); $name = str_replace(array("\r","\n"),array("",""),$name); $email = filter_var(trim($_POST["con_email"]), FILTER_SANITIZE_EMAIL); $message = trim($_POST["con_message"]); $check = strip_tags($_POST["check"]); $phone = strip_tags($_POST["con_phone"]); // Check that data was sent to the mailer. if ( empty($name) OR empty($message) OR empty($check) OR empty($phone) OR !filter_var($email, FILTER_VALIDATE_EMAIL)) { // Set a 400 (bad request) response code and exit. http_response_code(400); echo "Please complete the form and try again."; exit; } // Set the recipient email address. $recipient = "info@exemple.com"; // Set the email subject. $subject = "Test Email for Template Demo - Mail From $name"; // Build the email content. $email_content = "Name: $name\n"; $email_content .= "Email: $email\n\n"; $email_content .= "phone: $phone\n\n"; $email_content .= "check: $check\n\n"; $email_content .= "Message:\n$message\n"; // Build the email headers. $email_headers = "From: $name <$email>"; // Send the email. if (mail($recipient, $subject, $email_content, $email_headers)) { // Set a 200 (okay) response code. http_response_code(200); echo "Thank You! Your message has been sent."; } else { // Set a 500 (internal server error) response code. http_response_code(500); echo "Oops! Something went wrong and we couldn't send your message."; } } else { // Not a POST request, set a 403 (forbidden) response code. http_response_code(403); echo "There was a problem with your submission, please try again."; }?>
