Codeigniter Composer Phpmailer

Question

我正在通过Composer与Codeigniter + PHPMailer斗争.我收到这个错误:

Class 'PHPMailer' not found

我有CI版本3.1.5,我使用以下命令编写了PHPMailer 6.0.0:

composer require phpmailer/phpmailer

在我的根文件夹中,所以它创建了这样的东西:

/CI_root
 |-- application
 |-- system
 |-- vendor
 |   |-- phpmailer
 |       |-- phpmailer
 |           |-- language
 |           |-- src
 |-- composer.json

在我的application/config/config.php里面有这一行

$config['composer_autoload'] = FCPATH."vendor/autoload.php";

PS:我试图改变到$config['composer_autoload'] = "./vendor/autoload.php";以及

最后,根composer.json

},

    "phpmailer/phpmailer": "^6.0",
    "mpdf/mpdf": "^6.1"
},

},
"require-dev": {
    "mikey179/vfsStream": "1.1.*",
    "phpunit/phpunit": "4.* || 5.*"
}

}

在控制器内部

public function index()
{
    $mail = new PHPMailer();
    // other of stuff

有趣的是mpdf加载好了.我在这里错过了什么吗？

提前致谢!

Answer 1

Composer自动加载应该是TRUE:

$config['composer_autoload'] = TRUE;

这是因为CodeIgniter已经知道您的作曲家自动加载文件将在 /application/vendor

在您要使用PHP邮件程序的文件顶部,可能需要以下内容:

use PHPMailer;

实际上,在PHPMailer文档中,它们显示:

//Import PHPMailer classes into the global namespace
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
