Composer and PHPMailer issue

[gmc1103]

Hi

 

Can someone help me with the following issue

 

Fatal error: Class 'PHPMailer' not found 

 

I have installed the phpmailer from composer....so i don't undertstand whats going on

 This is my composer.json

{
  "name": "vendor_name/package_name",
  "description": "site esmaior",
  "minimum-stability": "stable",
  "license": "proprietary",
  "authors": [
    {
      "name": "GMC",
      "email": "[email protected]"
    }
  ],
  "require": {
    "phpmailer/phpmailer": "6.0.x-dev"
  }
}

This is my function to send email file "class.esmaior.pt"

 public function enviarEmailVisitas(){
        $mail = new PHPMailer;
        $mail->isSendmail();
        $mail->setFrom('[email protected]', 'First Last');
        $mail->addReplyTo('[email protected]', 'First Last');
        $mail->addAddress('[email protected]', 'John Doe');
        $mail->Subject = 'PHPMailer sendmail test';
        $mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));
        $mail->AltBody = 'This is a plain-text message body';
        $mail->addAttachment('images/phpmailer_mini.png');
        if (!$mail->send()) {
            echo "Mailer Error: " . $mail->ErrorInfo;
        } else {
            echo "Message sent!";
        }
    }

And the autoload is inserted in the file "class.esmaior.pt"

error_reporting(E_ALL | E_NOTICE);
ini_set('display_errors', '1');
require_once "dbconfig.php";
require_once __DIR__ . '/../vendor/autoload.php';
setlocale(LC_ALL, NULL);
setlocale(LC_ALL, 'pt_PT');

Any help,

The problem was here:

I miss those lines

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
