PHP Mailer causing rest of site to not be displayed

reddragon88 · Sep 15, 2022

I am currently designing a website in vs code that uses a login and registration form, mysql database using phpmyadmin via mamp on macos with m1 chip. The problem is, once I implemented PHPMailer, the content of my site won't load.

Here is the registration page:

Code:

<?php
include_once('templates/header.php');
include('config/dbh.php');
include('includes/functions.php');
include('mail/welcomemail.php');

//declare variables
$firstName = $lastName = $phoneNumber = $emailAddress = $companyName = $numberOfUsers = $password = $confirmPassword = "";

$firstErr = $lastErr = $phoneErr = $emailErr = $companyErr = $numUsrErr = $pwErr = $cpwErr = $stmtErr = "";

$errors = array('firstErr' => '', 'lastErr' => '', 'phoneErr' => '', 'emailErr' => '', 'companyErr' => '', 'numUsrErr' => '', 'pwErr' => '', 'cpwErr' => '', 'stmtErr' => '');


if ($_SERVER["REQUEST_METHOD"] == "POST") {

  // first name 
  if (!empty($_POST["firstName"])) {
    $firstName = test_input($_POST["firstName"]);
    if (!preg_match("/^[a-zA-Z\s]+$/", $firstName)) {
      $errors['firstErr'] = " * Only letters and white space allowed";
    }
  } else {
    $errors['firstErr'] = " * Required";
  }

  // last name
  if (!empty($_POST["lastName"])) {
    $lastName = test_input($_POST["lastName"]);
    if (!preg_match("/^[a-zA-Z\s]+$/", $lastName)) {
      $errors['lastErr'] = " * Only letters and white space allowed";
    }
  } else {
    $errors['lastErr'] = " * Required";
  }

  // phone number
  if (!empty($_POST["phoneNumber"])) {
    $phoneNumber = test_input($_POST["phoneNumber"]);
    if (!preg_match("/^[0-9]{10}+$/", $phoneNumber)) {
      $errors['phoneErr'] = " * Must contain 10 digits";
    }
  } else {
    $errors['phoneErr'] = " * Required";
  }

  // email
  if (!empty($_POST["emailAddress"])) {
    $emailAddress = test_input($_POST["emailAddress"]);
    if (!filter_var($emailAddress, FILTER_VALIDATE_EMAIL)) {
      $errors['emailErr'] = " * Invalid email address";
    } else if (emailExists($conn, $emailAddress) == "true") {
      $errors['emailErr'] = " * Email is already in use";
    }
  } else {
    $errors['emailErr'] = " * Required";
  }

  // company
  if (!empty($_POST["companyName"])) {
    $companyName = test_input($_POST["companyName"]);
    if (!preg_match("/^[a-zA-Z0-9\s]+$/", $companyName)) {
      $errors['companyErr'] = " *  Only letters, numbers, and white space allowed";
    }
  } else {
    $errors['companyErr'] = " * Required";
  }

  // number of users
  if (!empty($_POST["numberOfUsers"])) {
    $numberOfUsers = test_input($_POST["numberOfUsers"]);
  } else {
    $errors['numUsrErr'] = " * Required";
  }

  // password
  if (!empty($_POST["password"])) {
    $password = test_input($_POST["password"]);

    $uppercase = preg_match('@[A-Z]@', $password);
    $lowercase = preg_match('@[a-z]@', $password);
    $number = preg_match('@[0-9]@', $password);
    $minchar = "8";

    if (!$uppercase || !$lowercase || !$number || strlen($password) < $minchar) {
      $errors['pwErr'] = " * Requires one uppercase, one lowercase, one number, and at least 8 characters in length";
    }
  } else {
    $errors['pwErr'] = " * Required";
  }

  // confirm password
  if (!empty($_POST["confirmPassword"])) {
    $confirmPassword = test_input($_POST["confirmPassword"]);
    if ($password !== $confirmPassword) {
      $errors['cpwErr'] = " * Passwords must match";
    }
  } else {
    $errors['cpwErr'] = " * Required";
  }

  if (!array_filter($errors)) {
    //generate random secure token 
    $token = openssl_random_pseudo_bytes(16);
    //convert binary to hexadecimal
    $token = bin2hex($token);

    if (createUser($conn, $firstName, $lastName, $phoneNumber, $emailAddress, $companyName, $numberOfUsers, $password, $token) == "true") {
      sendWelcomeEmail($firstName, $emailAddress, $token); // here is where the welcome email is sent
    } else {
      echo "Please try again.";
    }
  }
} //end of post check
?>

Here is the code for the sendwelcomeemail() function:

//Load Composer's autoloader

function sendWelcomeEmail($firstName, $emailAddress, $token)

  $fname = $firstName;
  $usrEmail = $emailAddress;
  $tkn = $token;

  $host = 'mail.*COMPANYNAME*.com;'; // removed for security purposes
  $from = 'mailer@*COMPANYNAME*.com';
  $fromname = '*COMPANYNAME*';
  $mailerpw = '*COMPANYPASSWORD*';

  $subject = 'Verify your email address with *COMPANYNAME*';

  $body = 'Welcome, ' . $fname . '!
  Thank you for creating an account with *COMPANYNAME*.
  Please verify your account and email address by clicking the link below.

  $mail = new PHPMailer(true);

  try {

    $mail->isSMTP();
    $mail->SMTPDebug = SMTP::DEBUG_SERVER;
    $mail->Host       = gethostbyname($host);
    $mail->Port       = 25;
    $mail->SMTPAuth   = true;
    $mail->Username   = $from;
    $mail->Password   = $mailerpw;

Add error logging:

Code:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

And show the output. Probably us something wrong with path to the file that you are including.
Addidtionally you should not print any output before you are manipulate the header:

Code:

echo 'message has been sent';
header("location: login.php?error=none");

Now the content is loading, the user's information is being saved to the database, and i am receiving this error:

Code:

Source map error: Error: request failed with status 404
Resource URL:  /assets/vendor/swiper/swiper-bundle.min.js
Source Map URL: swiper-bundle.min.js.map

Still no errors in php error log.

All of the functions look as if the email is being sent successfully but it is not being received.

these lines should display errors on the screen, if you want to log them in to file, you can add this:

Code:

ini_set('error_log', '/tmp/php-error.log');

then you will log the errors to the custom file.
Check also the path to the file, is the file assets/vendor/swiper/swiper-bundle.min.js exists?
