Php Form Validation (don't Know How To Split It In Two Different Pages)
I am working on a contact form in PHP. My knowledge of PHP is pretty much non-existent. I've tried for a while to get a HTML form to submit to PHP form to have its text fields val
Solution 1:
Here is a basic form send example. This can all be on one page. PHP at the top, before all the html loads to browser, <form> html down anywhere in the <body> of the html page:
EDIT: I have updated the code to include your PHP Emailer.
<?phpclassEmailEngine{
publicstaticfunctionSend($settings = false)
{
$email = (!empty($settings['email']))? $settings['email']:false;
$first_name = (!empty($settings['first-name']))? $settings['first-name']:false;
$last_name = (!empty($settings['last-name']))? $settings['last-name']:false;
$message = (!empty($settings['message']))? $settings['message']:false;
$alt_message = (!empty($settings['alt_message']))? $settings['alt_message']:'To view the message, please use an HTML compatible email viewer!';
require(__DIR__.'/PHPMailerAutoload.php');
$mail = new PHPMailer;
$mail->isSMTP(); // Set mailer to use SMTP$mail->Host = 'host_specified'; // Specify main and backup SMTP servers$mail->SMTPAuth = true; // Enable SMTP authentication$mail->Username = 'email_specified'; // SMTP username$mail->Password = 'password_specified'; // SMTP password$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted$mail->Port = 587;
$mail->addReplyTo( $email, $first_name );
$mail->addAddress( $email, $first_name );
$mail->addAddress( 'email_specified', 'Staff' );
$mail->From = 'email_specified';
$mail->FromName = 'Staff';
$mail->isHTML(true); // Set email format to HTML$mail->Subject = 'Hotel Room Request';
$mail->Body = $message;
$mail->AltBody = $alt_message;
return$mail->send();
}
}
// Just make an error reporting function to return errorsfunctionerror_report($val = false)
{
$array["first-name"] = "First name is required";
$array["last-name"] = "Last name is required";
$array["email"] = "Email is required";
$array["message"] = "A message is required";
return (isset($array[$val]))? $array[$val] :false;
}
// Sanitize. I add false so no error is thrown if not setfunctionsanitize_vals($data = false)
{
if(empty($data))
returnfalse;
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return$data;
}
// If a value is posted (any will do from your form) process the rest of the $_POSTif(isset($_POST["first-name"])) {
// Just loop through the $_POST instead of doing all the manual if/else...foreach($_POSTas$key => $value) {
// This specifically processes your email addressif(($key == 'email')) {
// If not valid email, send to errorsif(!filter_var($value,FILTER_VALIDATE_EMAIL))
$errors[$key] = error_report('email');
else$payload[$key] = $value;
}
// This processes the restelse {
$value = sanitize_vals($value);
// Checks for emptyif(empty($value))
$errors[$key] = error_report($key);
else$payload[$key] = $value;
}
}
// If all is good and no errors set, send the emailif(!isset($errors)) {
// SEND MAIL HERE.$page = (EmailEngine::Send($payload))? "Result" : "Error";
header("Location: url/contact{$page}.html");
exit;
}
}

<?php
session_start(); //allows use of session variablesif ($_SERVER["REQUEST_METHOD"] == "POST") {

{
$_SESSION['first_name'] = $first_name;
$_SESSION['last_name'] = $last_name;
$_SESSION['email'] = $email;
$_SESSION['message'] = $message;
header("Location: php_mailer_form.php");
}
}
functiontest_input($data) {
$data = trim($data);

$data = htmlspecialchars($data);
return$data;
}

Does this answer your question? Also note, I edited the html so that the error message div only prints if the error variable was set.
