Fatal error: Class 'PHPMailer' not found

问题

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 ?

回答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all answers are outdated now.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("xxxxxx@xxxxx.com");
    $mail->Subject = "Test";
    $mail->Body = "hello";
    $mail->AddAddress("xxxxxx@xxxxx.com");

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

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

Download the package from https://github.com/PHPMailer/PHPMailer by clicking on the "Download ZIP" button on the far lower right of the page.
extract the zip file
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.
Include the class in your PHP project: require_once('phpmailer/PHPMailerAutoload.php');

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';

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 = "foo@gmail.com";
    $mail->Password = "*******";

    //Set Params
    $mail->SetFrom("foo@gmail.com");
    $mail->AddAddress("bar@gmail.com");
    $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.

I suggest you look into getting composer. https://getcomposer.org Composer makes getting third-party libraries a LOT easier and using a single autoloader for all of them. It also standardizes on where all your dependencies are located, along with some automatization capabilities.

Download https://getcomposer.org/composer.phar to C:\Inetpub\wwwroot\php

Delete your C:\Inetpub\wwwroot\php\PHPMailer\ directory.

Use composer.phar to get the phpmailer package using the command line to execute

cd C:\Inetpub\wwwroot\php
php composer.phar require phpmailer/phpmailer

After it is finished it will create a C:\Inetpub\wwwroot\php\vendor directory along with all of the phpmailer files and generate an autoloader.

Next in your main project configuration file you need to include the autoload file.

require_once 'C:\Inetpub\wwwroot\php\vendor\autoload.php';

The vendor\autoload.php will include the information for you to use $mail = new \PHPMailer;

Additional information on the PHPMailer package can be found at https://packagist.org/packages/phpmailer/phpmailer

I was with the same problem except with a slight difference, the version of PHPMailer 6.0, by the good friend avs099 I know that the new version of PHPMailer since February 2018 does not support the autoload, and had a serious problem to instantiate the libraries with the namespace in MVC, I leave the code for those who need it.

//Controller
    protected function getLibraryWNS($libreria) {
    $rutaLibreria = ROOT . 'libs' . DS . $libreria . '.php';

    if(is_readable($rutaLibreria)){
        require_once $rutaLibreria;
        echo $rutaLibreria . '<br/>';
    }
    else{
        throw new Exception('Error de libreria');
    }
}

//loginController
    public function enviarEmail($email, $nombre, $asunto, $cuerpo){
    //Import the PHPMailer class into the global namespace
            $this->getLibraryWNS('PHPMailer');
            $this->getLibraryWNS('SMTP');
    //Create a new PHPMailer instance
            $mail = new \PHPMailer\PHPMailer\PHPMailer();
    //Tell PHPMailer to use SMTP
            $mail->isSMTP();
    //Enable SMTP debugging
    //      $mail->SMTPDebug = 0;                                       // 0 = off (for production use),  1 = client messages, 2 = client and server messages  Godaddy POR CONFIRMAR
            $mail->SMTPDebug = 1;                                       // debugging: 1 = errors and messages, 2 = messages only
    //Whether to use SMTP authentication
            $mail->SMTPAuth = true;                                     // authentication enabled
    //Set the encryption system to use - ssl (deprecated) or tls
            $mail->SMTPSecure = 'ssl';                                  //Seguridad Correo Gmail
    //Set the hostname of the mail server
            $mail->Host = "smtp.gmail.com";                             //Host Correo Gmail
    //Set the SMTP port number - 587 for authenticated TLS, a.k.a. RFC4409 SMTP submission
            $mail->Port = 465;      //587;
    //Verifica si el servidor acepta envios en HTML
            $mail->IsHTML(true);
    //Username to use for SMTP authentication - use full email address for gmail
            $mail->Username = 'tumail@gmail.com';
    //Password to use for SMTP authentication
            $mail->Password = 'tucontraseña';
    //Set who the message is to be sent from
            $mail->setFrom('tumail@gmail.com','Creador de Páginas Web');
            $mail->Subject = $asunto;
            $mail->Body = $cuerpo;
    //Set who the message is to be sent to
            $mail->addAddress($email, $nombre);
    //Send the message, check for errors
    if(!$mail->Send()) {
        echo "Mailer Error: " . $mail->ErrorInfo;
        return false;
    } else {
        echo "Message has been sent";
        return true;
    }

回答7:

Just from reading what you have written, you will need to add the file class.phpmailer.php to your directory as well.

回答8:

PHPMailerAutoload needs to be in the same folder as class.phpmailer.php

This is the PHPMailerAutoload code that I assume this:

 $filename = dirname(__FILE__).DIRECTORY_SEPARATOR.'class.'.strtolower($classname).'.php';

回答9:

Just download composer and install phpMailler autoloader.php

https://github.com/PHPMailer/PHPMailer/blob/master/composer.json

once composer is loaded use below code:

    require_once("phpMailer/class.phpmailer.php");
    require_once("phpMailer/PHPMailerAutoload.php");

    $mail = new PHPMailer(true); 
            $mail->SMTPDebug = true;
            $mail->SMTPSecure = "tls";
            $mail->SMTPAuth   = true;
            $mail->Username   = 'youremail id';
            $mail->Password   = 'youremail password';
            $mail_from        = "youremail id";
            $subject          = "Your Subject";
            $body             = "email body";
            $mail_to          = "receiver_email";
            $mail->IsSMTP(); 
            try {
                  $mail->Host= "smtp.your.com";
                  $mail->Port = "Your SMTP Port No";// ssl port :465, 
                  $mail->Debugoutput = 'html';
                  $mail->AddAddress($mail_to, "receiver_name");
                  $mail->SetFrom($mail_from,'AmpleChat Team'); 
                  $mail->Subject = $subject;
                  $mail->MsgHTML($body);
                  $mail->Send();
                 $emailreturn = 200;
                } catch (phpmailerException $e) {
                  $emailreturn = $e->errorMessage();             
                } catch (Exception $e) {
                 $emailreturn = $e->getMessage();
                }
    echo $emailreturn;

Hope this will work.

I had a number of errors similar to this. Make sure your setFrom email address is valid in $mail->setFrom()
