在一封电子邮件中发送多行答案

【问题标题】：Send multiple rows in one email在一封电子邮件中发送多行

【问题描述】：

我希望能够将数据库中的多行发送到一封电子邮件中。到目前为止，我得到的只是两封（或更多）电子邮件，每封电子邮件都包含一行。如何将所有内容都放入一封电子邮件？

这是我的代码。将 mail() 保留在 while 循环之外只会给我最后一个条目。将其保留在 while 循环中会发送两封电子邮件。

        $sql = "SELECT productid, kind, qty, price, GROUP_CONCAT(product) as product FROM orderitems LEFT JOIN Products ON orderitems.code = Products.productid WHERE orderitems.customerid = $customerid GROUP BY productid";
        $result = mysqli_query($db, $sql) or die(mysqli_error($db));
        while($row = mysqli_fetch_array($result)) {
          $product = $row['product'];
          $productid = $row['productid']; 

          $to = "email@gmail.com";
          $subject = "Order";
          $emailBody = "ID: ".$product."\n"."Product: ".$productid."\n";
          $emailBody .= "Total: ".$total."\n";
          $headers = 'From: Email <no-reply@someemailaddress>' . "\r\n" .
              'Reply-To: someemailaddress' . "\r\n" .
              'X-Mailer: PHP/' . phpversion();
          mail($to, $subject, $emailBody, $headers); }

如果有人能在正确的方向上推动我，我会非常高兴！

我想你只想重复这个字符串。

ID: ".$product."\n"."Product: ".$productid."\n";

所以它应该在循环中，而其他不应该。喜欢：

$sql = "SELECT productid, kind, qty, price, GROUP_CONCAT(product) as product FROM orderitems LEFT JOIN Products ON orderitems.code = Products.productid WHERE orderitems.customerid = $customerid GROUP BY productid";
$result = mysqli_query($db, $sql) or die(mysqli_error($db));

$emailBody = '';
$total = 0;//I dont know what is total for you

while($row = mysqli_fetch_array($result)) {
    $product = $row['product'];
    $productid = $row['productid']; 

    $emailBody .= "ID: ".$product."\n"."Product: ".$productid."\n";
    $total = $total + 1; //Just for example

}
$to = "email@gmail.com";
$subject = "Order";
$emailBody .= "Total: ".$total."\n";
$headers = 'From: Email <no-reply@someemailaddress>' . "\r\n" .
     'Reply-To: someemailaddress' . "\r\n" .
     'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $emailBody, $headers);

不幸的是，这仍然只给了我最后一个条目！
谢谢！像魅力一样工作！

问题在于您在 while 循环中有 mail() 函数，因此对于每个循环，该函数都会发送一封电子邮件。
您可以从循环中提取 mail()，并且只收集循环内需要的行，如下所示：

    $emailBody = '';
    while($row = mysqli_fetch_array($result)) {
      $product = $row['product'];
      $productid = $row['productid']; 
      $emailBody .= "ID: ".$product."\n"."Product: ".$productid."\n";
      $emailBody .= "Total: ".$total."\n";
    }

    $to = "email@gmail.com";
    $subject = "Order";          
    $headers = 'From: Email <no-reply@someemailaddress>' . "\r\n" .
          'Reply-To: someemailaddress' . "\r\n" .
          'X-Mailer: PHP/' . phpversion();
    mail($to, $subject, $emailBody, $headers); }
