Swiftmailer - Uncaught Error: Call to undefined method Swift_SmtpTransport::newInstance()

Question

I'm trying to send email using the Swiftmailer.

I'm getting an Uncaught Error:

Call to undefined method Swift_SmtpTransport::newInstance().

Here is the code:

require_once 'swift/lib/swift_required.php';

$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')
      ->setUsername ('email@gmail.com')
      ->setPassword ('password');

$mailer = Swift_Mailer::newInstance($transport);

$message = Swift_Message::newInstance('Weekly Hours')
       ->setFrom (array('email@gmail.com' => 'My Name'))
       ->setTo (array('email@hotmail.com' => 'Recipient'))
       ->setSubject ('Weekly Hours')
       ->setBody ('Test Message', 'text/html');

$result = $mailer->send($message);

Based on the above code, what would be causing that mistake?

I'm not quite familiar with SwiftMailer, but from the brief overview of the error you provided, and their documentation page, I can suggest you to try using new operator. From the error, it's clear that Swift_SmtpTransport class doesn't have a newInstance method, so when you use it to create a new instance, it throws an error. Maybe try using this instead:

require_once 'swift/lib/swift_required.php';

$transport = new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl');
$transport->setUsername('email@gmail.com')->setPassword('password');

$mailer = new Swift_Mailer($transport);

$message = new Swift_Message('Weekly Hours');
$message
   ->setFrom(['email@gmail.com' => 'My Name'])
   ->setTo(['email@hotmail.com' => 'Recipient'])
   ->setSubject('Weekly Hours')
   ->setBody('Test Message', 'text/html');

$result = $mailer->send($message);

Edit: PHP Doesn't allow a direct method call after instantiating an object (without parenthesis). Thanks, Art Geigel.

I needed to put parentheses around the new object to get it to work like so: $transport = (new Swift_SmtpTransport('smtp.gmail.com', 465, 'ssl')) — Art Geigel, Mar 20 '18 at 23:25
Yeah, forgot that PHP doesn't allow direct usage of the instance. Personally I don't find parenthesis around the object very readable, so I'll leave it the simple way haha. Thanks for your comment! @ArtGeigel — Luka Kvavilashvili, Apr 02 '19 at 16:43

Swift_Mailer::newInstance($transport);

The newInstance method is available in version 5.4, in newer version, it is removed. Check version in composer.json.

"swiftmailer/swiftmailer": "^5.4"

add this lines in file : ./swift/classes/Swift/SmtpTransport.php

/**
 * Create a new SmtpTransport instance.
 *
 * @param string  $host
 * @param integer $port
 * @param string  $security
 *
 * @return Swift_SmtpTransport
 */
public static function newInstance($host = 'localhost', $port = 25, $security = null)
{
    return new self($host, $port, $security);
}

it was deleted in new version, but if you update from github, you need everytime add it
