Question

一点背景，

我正在创建一个简单的功能，只要博客管理员创建新公告，就会向所有用户发送电子邮件。我想使用sql查询收集所有电子邮件并将它们全部输入到邮件正文中，或者可能循环发送一次一封电子邮件（虽然看起来可能需要更长时间）。

到目前为止，这是我的代码：

 public function emailAll()
    {
        $this->set_mail_settings();
        $message = new YiiMailMessage;        

        $request = Yii::app()->db->createCommand("
                                    SELECT email FROM persons WHERE party_id
                                ")->queryRow();

                $message->subject = 'Star Cruises - Login Information';
                $message->addTo('sendTo@someone.com');
                $message->from = Yii::app()->params['adminEmail'];
                Yii::app()->mail->send($message);
                exit();

        }

 private function set_mail_settings()
    {            
        $sysParam = SystemParameters::model()->getSystemParameters(
        array("smtp_host", "smtp_port", 'smtp_user','smtp_password')
    );

        Yii::app()->mail->transportOptions['username'] = $sysParam['smtp_user'];
        Yii::app()->mail->transportOptions['password'] = $sysParam['smtp_password'];
        Yii::app()->mail->transportOptions['host'] = $sysParam['smtp_host'];
        Yii::app()->mail->transportOptions['port'] = $sysParam['smtp_port'];
    }

只要使用电子邮件，就会调用emailAll（）函数。

我的问题是$ request。我不知道如何收集所有电子邮件并将它们放入$ message-＆gt; addTo（）;

更新：我做得很好，直到我达到这一点：

    public function emailAll()
    {

        $this->set_mail_settings();
        $message = new YiiMailMessage;        

                $emails = Yii::app()->db->createCommand("SELECT group_concat(email) as em FROM persons")->queryRow();
                $email_ids = explode(",",$emails["em"]);
                $message->setBcc($email_ids);
                $message->setBody('Sample');
                $message->subject = 'New Announcement!';
                //$message->addTo('blah@blah.com');
                $message->from = Yii::app()->params['adminEmail'];
                Yii::app()->mail->send($message);


        }

 private function set_mail_settings()
    {            
        $sysParam = SystemParameters::model()->getSystemParameters(
        array("smtp_host", "smtp_port", 'smtp_user','smtp_password')
    );

        Yii::app()->mail->transportOptions['username'] = $sysParam['smtp_user'];
        Yii::app()->mail->transportOptions['password'] = $sysParam['smtp_password'];
        Yii::app()->mail->transportOptions['host'] = $sysParam['smtp_host'];
        Yii::app()->mail->transportOptions['port'] = $sysParam['smtp_port'];
    }

然后我从YiiMail.php获得了这一行的错误：

 189         $msg = 'Sending email to '.implode(', ', array_keys($message->to))."\n".

它声明：array_keys（）期望参数1为数组，给定为null。

我明白它想要什么，但我不明白为什么会出现这个错误？

您可以使用以下查询获取所有电子邮件ID，并出于安全原因使用BCC代替To。

$emails = Yii::app()->db->createCommand("SELECT group_concat(email) as em FROM persons WHERE party_id = $party_id")->queryRow();
$email_ids = explode(",",$emails["em"]);
$message->setBcc($email_ids); // use bcc to hide email ids from other users
$message->addTo("noreply@yourdomain.com"); //as To is required, set some dummy id or your own id.

尝试使用Yiimail从数据库中获取电子邮件
