Fatal error: Class 'PHPMailer' not found

• I tried :include_once('C:\Inetpub\wwwroot\php\PHPMailer\PHPMailerAutoload.php');

Fatal error: Class 'PHPMailer' not found in C:\Inetpub\wwwroot\php\index.php on line 151

I place the PHPMailerAutoload.php in the same directory as my script.

Can someone help me with this ?

Solution 1:

all answers are outdated now. Most current version (as of Feb 2018) does not have autoload anymore, and PHPMailer should be initialized as follows:

<?php

  require("/home/site/libs/PHPMailer-master/src/PHPMailer.php");
  require("/home/site/libs/PHPMailer-master/src/SMTP.php");

    $mail = new PHPMailer\PHPMailer\PHPMailer();
    $mail->IsSMTP(); // enable SMTP

    $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
    $mail->SMTPAuth = true; // authentication enabled
    $mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
    $mail->Host = "smtp.gmail.com";
    $mail->Port = 465; // or 587
    $mail->IsHTML(true);
    $mail->Username = "xxxxxx";
    $mail->Password = "xxxx";
    $mail->SetFrom("[email protected]");
    $mail->Subject = "Test";
    $mail->Body = "hello";
    $mail->AddAddress("[email protected]");

     if(!$mail->Send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;
     } else {
        echo "Message has been sent";
     }
?>

Solution 2:

This answers in an extension to what avs099 has given above, for those who are still having problems:

1.Makesure that you have php_openssl.dll installed(else find it online and install it);

2.Go to your php.ini; find extension=php_openssl.dll enable it/uncomment

3.Go to github and downland the latetest version :6.0 at this time.

4.Extract the master copy into the path that works better for you(I recommend the same directory as the calling file)

Now copy this code into your foo-mailer.php and render it with your gmail stmp authentications.

    require("/PHPMailer-master/src/PHPMailer.php");
    require("/PHPMailer-master/src/SMTP.php");
    require("/PHPMailer-master/src/Exception.php");


    $mail = new PHPMailer\PHPMailer\PHPMailer();
    $mail->IsSMTP(); 

    $mail->CharSet="UTF-8";
    $mail->Host = "smtp.gmail.com";
    $mail->SMTPDebug = 1; 
    $mail->Port = 465 ; //465 or 587

     $mail->SMTPSecure = 'ssl';  
    $mail->SMTPAuth = true; 
    $mail->IsHTML(true);

    //Authentication
    $mail->Username = "[email protected]";
    $mail->Password = "*******";

    //Set Params
    $mail->SetFrom("[email protected]");
    $mail->AddAddress("[email protected]");
    $mail->Subject = "Test";
    $mail->Body = "hello";


     if(!$mail->Send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;
     } else {
        echo "Message has been sent";
     }

Disclaimer:The original owner of the code above is avs099 with just my little input.

Take note of the additional:

a) (PHPMailer\PHPMailer) namespace:needed for name conflict resolution.

b) The (require("/PHPMailer-master/src/Exception.php");):It was missing in avs099's code thus the problem encountered by aProgger,you need that line to tell the mailer class where the Exception class is located.

Solution 3:

Doesn't sound like all the files needed to use that class are present. I would start over:

1. Download the package from https://github.com/PHPMailer/PHPMailer by clicking on the "Download ZIP" button on the far lower right of the page.
2. extract the zip file
3. upload the language folder, class.phpmailer.php, class.pop3.php, class.smtp.php, and PHPMailerAutoload.php all into the same directory on your server, I like to create a directory on the server called phpmailer to place all of these into.
4. Include the class in your PHP project: require_once('phpmailer/PHPMailerAutoload.php');

Solution 4:

This is just namespacing. Look at the examples for reference - you need to either use the namespaced class or reference it absolutely, for example:

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

//Load composer's autoloader
require 'vendor/autoload.php';
