Form Not Submitting PHP - php

Question

I am having some trouble, I am trying to submit a form with php and phpmailer.
So what I did is trying to make a form following w3school complete form example and then I wondered if I could send it through email. I found phpmailer and I tried using it but it is not sending.
I am using the $contactsend to know if I can send form or not (after the validation have been done). So in case $contactsend is 0 then I cannot send and if it is 1 then I can send the form.
However I am almost sure that there is an issue with it but I don't know why.
How can I understand what is going wrong?
Here is the code I have :
<?php
$contactnameErr = $emailErr = $phoneErr = $subjectErr = $messageErr = "";
$contactname = $email = $phone = $subject = $message = "";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
$contactsend= 1;
if (empty($_POST["contactname"])) {
$contactnameErr = "* Name is required";
$contactsend= 0;
} else {
$contactname = test_input($_POST["contactname"]);
// check if name only contains letters and whitespace
if (!preg_match("/^[a-zA-Z ]*$/",$contactname)) {
$contactnameErr = "* Only letters and white space allowed";
$contactsend= 0;
}
}
if (empty($_POST["contactemail"])) {
$contactemailErr = "* Email is required";
$contactsend= 0;
} else {
$contactemail = test_input($_POST["contactemail"]);
// check if e-mail address is well-formed
if (!filter_var($contactemail, FILTER_VALIDATE_EMAIL)) {
$contactemailErr = "* Invalid email format";
$contactsend= 0;
}
}
if (empty($_POST["contactphone"])) {
$contactphoneErr = "* Phone is required";
$contactsend= 0;
} else {
$contactphone = test_input($_POST["contactphone"]);
$contactsend= 0;
}
if (empty($_POST["contactsubject"])) {
$contactsubjectErr = "* Subject is required";
$contactsend= 0;
} else {
$contactsubject = test_input($_POST["contactsubject"]);
$contactsend= 0;
}
if (empty($_POST["contactmessage"])) {
$contactmessageErr = "* Message is required";
$contactsend= 0;
} else {
$contactmessage = test_input($_POST["contactmessage"]);
$contactsend= 0;
}
echo $contactsend;
if($contactsend== 1)
{
//send mail
$message = "\nSpecial Events , Contact Us . \nName : " . $contactname . "\nEmail : " . $contactemail . "\nPhone : " . $contactphone
. "\nSubject : " . $contactsubject ."\nMessage : " . $contactmessage;
require("/home/specialeventsleb/public_html/phpmailer/PHPMailer/class.phpmailer.php");
$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host = 'smtp.office365.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = 'email1';
$mail->Password = 'password1';
$mail->SetFrom('email1', 'FromEmail');
$mail->AddAddress('email1', 'ToEmail');
$mail->AddAddress('email2', 'ToEmail1');
$mail->AddAddress('email3', 'ToEmail2');
$mail->SMTPDebug = true;
$mail->Timeout = 2000;
$mail->Debugoutput = function($str, $level) {echo "debug level $level; message: $str";};
$mail->Debugoutput = 'echo';
$mail->Subject = 'Message from Special Events Website';
$mail->Body = $message;
$mail->send();
}
}
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>
<div id="ContactUs">

Answer 1

First the operations you're checking with if($contactsend== 1) are not called because your script forces $contactsend = 0 checking "contactsubject", "contactphone", "contactmessage"..
Then you have to set these
$mail->SetFrom('email1', 'FromEmail');
$mail->AddAddress('email1', 'ToEmail');
$mail->AddAddress('email2', 'ToEmail1');
$mail->AddAddress('email3', 'ToEmail2');
with valid email addresses..
Example with
$mail->AddAddress($contactemail, 'ToEmail');
which get the value from the POST
