php – Opencart在自定义脚本中发送电子邮件

我的opencart中有一个脚本,由我自己制作,并希望让它发送一封电子邮件,但我认为当我尝试获取电子邮件参数时,它们会返回null.

这是我的代码：

$email_to = "[e-mail]";
    $config = new Config();
    $mail = new Mail();


    $mail->protocol = $config->get('config_mail_protocol');
    $mail->parameter = $config->get('config_mail_parameter');
    $mail->hostname = $config->get('config_smtp_host');
    $mail->username = $config->get('config_smtp_username');
    $mail->password = $config->get('config_smtp_password');
    $mail->port = $config->get('config_smtp_port');
    $mail->timeout = $config->get('config_smtp_timeout');            
    $mail->setTo($email_to);
    $mail->setFrom("nuno@[mydomain].com");
    $mail->setSender("nuno@[mydomain].com");
    $mail->setSubject("test send mail");
    $mail->setText("test message body text");
    $mail->send();

当我尝试呼叫时：echo $config-> get(‘config_mail_protocol’);它返回null.

不要创建Config的新实例,只需简单地调用即可

$email_to = "[e-mail]";
$mail = new Mail();

$mail->protocol = $this->config->get('config_mail_protocol');
$mail->parameter = $this->config->get('config_mail_parameter');
$mail->hostname = $this->config->get('config_smtp_host');
$mail->username = $this->config->get('config_smtp_username');
$mail->password = $this->config->get('config_smtp_password');
$mail->port = $this->config->get('config_smtp_port');
$mail->timeout = $this->config->get('config_smtp_timeout');            
$mail->setTo($email_to);
$mail->setFrom("[e-mail]");
$mail->setSender("[e-mail]");
$mail->setSubject("test send mail");
$mail->setText("test message body text");

$mail->send();
