Yii2-批量发送邮件

Question

我想使用 yii2 mailer 发送电子邮件。我已经配置了邮件程序并且已经尝试在一封电子邮件中发送一条记录。现在我想在一封电子邮件中发送多条记录。

下面是我的动作控制器

 $sql = "SELECT COUNT(DISTINCT od.`meter_serial`) AS 'OGP Created', 
         COUNT(DISTINCT mp.`meter_id`) AS 'Installed & Un-Verified Meters', 
         COUNT(DISTINCT ins.`meter_msn`) AS 'Installed & Verified', 
         sd.`sub_div_code` AS 'SD Code',sd.`name` AS 'SD-Name'
         FROM `ogp_detail` od
         INNER JOIN `survey_hesco_subdivision` sd ON od.`sub_div` = 
         sd.`sub_div_code`
         LEFT JOIN `meter_ping` mp ON od.`meter_id` = mp.`meter_id`
         LEFT JOIN `installations` ins ON od.`meter_serial` = ins.`meter_msn`
         WHERE od.`meter_type` = '3-Phase'
         GROUP BY sd.`name`";
    $result = Yii::$app->db->createCommand($sql)->queryAll();
    print_r($result);
    exit();

输出是

正如上面的结果，我想在一封电子邮件中发送多条记录。

我还想将 OGP Created、'Installed & Un-Verified Meters' 和 'Installed & Verified' 计数值相加，即将它们求和到一个单独的变量中

根据建议，csv 附件可以。但是我还想补充一点。正如我上面所说，我想 sum up 所有前三列的计数值。所以我尝试像这样添加它们

 foreach ($result as $set)
    {
        $sum_OGP +=$set['OGP_Created'];
        $sum_UnVerified +=$set['Installed _& _Un_Verified_Meters'];
        $sum_Verified +=$set['Installed_& _Verified_Meters'];
    }

    echo "Total OGP ";
    print_r($sum_OGP);
    echo "<br>";
    echo "<br>";
    echo "Total Un-Verified Meters ";
    print_r($sum_UnVerified);
    echo "<br>";
    echo "<br>";
    echo "Total Verified Meters ";
    print_r($sum_Verified);
    exit();

而 output 是

Total OGP 2813

Total Un-Verified Meters 712

Total Verified Meters 181

总和是正确的，但我如何在附件中发送它？

非常感谢任何帮助。

如果您想将查询的输出发送到电子邮件中，那么您应该创建一个 csv 文件并通过电子邮件作为附件发送。

public function test() {
    $sql = "SELECT COUNT(DISTINCT od.`meter_serial`) AS 'OGP Created', 
     COUNT(DISTINCT mp.`meter_id`) AS 'Installed & Un-Verified Meters', 
     COUNT(DISTINCT ins.`meter_msn`) AS 'Installed & Verified', 
     sd.`sub_div_code` AS 'SD Code',sd.`name` AS 'SD-Name'
     FROM `ogp_detail` od
     INNER JOIN `survey_hesco_subdivision` sd ON od.`sub_div` = 
     sd.`sub_div_code`
     LEFT JOIN `meter_ping` mp ON od.`meter_id` = mp.`meter_id`
     LEFT JOIN `installations` ins ON od.`meter_serial` = ins.`meter_msn`
     WHERE od.`meter_type` = '3-Phase'
     GROUP BY sd.`name`";
    $results = Yii::$app->db->createCommand($sql)->queryAll();

    //create a csv file
    $filename   =   $this->getAttachment($results);

    //send email 
    $this->sendEmail('omer@omer.com',$filename);
}

/**
 * 
 * @param type $email
 * @param type $filename
 * @return type
 */
public function sendEmail($email,$filename)
{
    return Yii::$app->mailer->compose()
        ->setTo($email)
        ->setFrom(['admin@domain.com' => 'Admin'])
        ->setSubject('Some Subject for the email')
        ->setTextBody('Text body of the email ')
        ->attach($filename,['filename'=>'information','contentType'=>'text/csv'])
        ->send();
}

/**
 * 
 * @param type $results
 * @return string $filename
 */
public function getAttachment($results) {
    $filename = Yii::getAlias('@webroot') . DIRECTORY_SEPARATOR . 'my-attachment-' . time() . '.csv';

    //open a csv file
    $file = fopen($filename, "w");

    $headerInjected = false;
    $header = ['OGP Created', 'Installed & Un-Verified Meters', 'Installed & Verified', 'SD Code', 'SD-Name'];

    //write lines to the csv file 
    foreach ($results as $result) {
        if (!$headerInjected) {
            $headerInjected = true;
            fputcsv($file, $header);
        }
        fputcsv($file, $result);
        $sum_OGP +=$result['OGP_Created'];
        $sum_UnVerified +=$result['Installed_&_Un_Verified_Meters'];
        $sum_Verified +=$result['Installed_&_Verified_Meters'];
    }

    //add the sum in the last row
    fputcsv($file,[$sum_OGP,$sum_UnVerified,$sum_Verified]);

    //close the file handle
    fclose($file);
    return $filename;
}
