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。

以下是我的动作控制器

 $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

如上所述，我想在一封电子邮件中发送多条记录。

我还要加OGP Created，'已安装＆amp;未经验证的仪表'和'已安装＆amp;已验证的'计数值，即将它们与单独的变量相加

根据建议，csv附件可以使用。但是我想补充一些东西。正如我上面所说，我希望sum up所有前三列的计数值。所以我试图像这样添加它们

 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，但如何将其发送到附件？

任何帮助都将受到高度赞赏。

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;
}
