PHPMailer not working: Is there a new way of doing this? - php

Question

I followed all of the instructions in this question:
SMTP connect() failed PHPmailer - PHP
But still I never succeeded in getting the PHPMailer to work. I searched elsewhere - no solutions.
You can view the results here: https://unidrones.co.za/JuneSecond
When I try to send a test email using my gmail account credentials, it returns the "SMTP connect() failed" error.
I am using this template code:
<?php
require 'PHPMailerAutoload.php';
if(isset($_POST['send']))
{
$email = $_POST['email'];
$password = $_POST['password'];
$to_id = $_POST['toid'];
$message = $_POST['message'];
$subject = $_POST['subject'];
$mail = new PHPMailer;
$mail->isSMTP();
$mail->Host = 'ssl://smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth = true;
$mail->Username = $email;
$mail->Password = $password;
$mail->addAddress($to_id);
$mail->Subject = $subject;
$mail->msgHTML($message);
if (!$mail->send()) {
$error = "Mailer Error: " . $mail->ErrorInfo;
echo '<p id="para">'.$error.'</p>';
}
else {
echo '<p id="para">Message sent!</p>';
}
}
else{
echo '<p id="para">Please enter valid data</p>';
}
?>
Edit: I don't know if there's a new way to send emails through PHP now. All the tutorials and lessons I am using teaches it this way (i.e. using the PHPMailer library).
I had a tough time finding the PHPMailer library that includes the PHPMailerAutoload.php file, which makes me think it's a little outdated or deprecated, but how else would I send emails? I don't know.

Answer 1

The reason you're having a hard time finding PHPMailerAutoload.php is because it's old and no longer supported. Get the latest and base your code on the gmail example provided. If you're new to PHP, learn to use composer.
These three lines are conflicting:
$mail->Host = 'ssl://smtp.gmail.com';
$mail->Port = 587;
$mail->SMTPSecure = 'tls';
The ssl:// in Host overrides the tls in SMTPSecure, resulting in it trying to use implicit TLS to a port expecting explicit TLS. Either use ssl with port 465 or tls with port 587, not other combos. Regardless, it appears that's not your problem anyway.
As the troubleshooting guide says about this exact "SMTP connect() failed" error:
This is often reported as a PHPMailer problem, but it's almost always down to local DNS failure, firewall blocking (for example as GoDaddy does) or another issue on your local network. It means that PHPMailer is unable to contact the SMTP server you have specified in the Host property, but doesn't say exactly why.
It then goes on to describe several techniques you can use to try to diagnose exactly why you can't connect. Amazing stuff, documentation.
I tried your form with some random data and saw that you failed to include the most important error message in your question:
2018-06-02 14:47:25 SMTP ERROR: Failed to connect to server: Network is unreachable (101)
2018-06-02 14:47:25 SMTP connect() failed
That suggests your ISP is probably blocking outbound SMTP, so you have your answer - perhaps confirm that using the steps the guide suggests (telnet etc), and refer to your ISP's docs or support.
You also have a major omission - you're not setting a "from" address:
$mail->setFrom('myname#gmail.com', 'My Name');
Note that if you're sending through gmail, you can only use your account's address, or preset aliases (set in gmail prefs), not arbitrary addresses.
Meanwhile, this is a somewhat crazy thing to implement as you have anyway - why would anyone ever enter their gmail credentials on a form like that?

Answer 2

did you try to use the following config?
$mail->Host = 'smtp.gmail.com';
$mail->SMTPSecure = 'ssl';
$mail->Port = 465;
$mail->CharSet = 'UTF-8';

<?php
require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
//$mail->SMTPDebug = 4; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'your gamil id'; // SMTP username
$mail->Password = 'gmail password'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to
$mail->setFrom('set from address', 'name');
$mail->addAddress('recipient address', 'Joe User'); // Add a recipient
$mail->addReplyTo('reply address', 'Information');
// $mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
// $mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
