我的PHP表单不会发送给多个用户

嗨，我有一个php表单，当它向一个人发送电子邮件时，它可以完美地工作，但当我添加另一个电子邮件地址时，它不会向任何一个地址发送电子邮件。我一直在搜索php网站，但不明白为什么我的表单现在拒绝在添加第二个电子邮件地址后发送电子邮件

   <?php 
    function isRequestSet( $name ) { 
if ( isset ( $_REQUEST[$name] ) ) { 
    return ( $_REQUEST[$name] != "" ) ;
}
return false;
    }

    $name = "";
     if ( isRequestSet('name' ) ) { 
$name = $_REQUEST['name'];
    } 
    $number = "";
    if ( isRequestSet('number') ) { 
$number = $_REQUEST['number'];
    }
    $email = "";
    if ( isRequestSet( 'email' ) ) { 
$email = $_REQUEST['email'];
    }
     $postcode = "";
     if ( isRequestSet('postcode' ) ) { 
$location = $_REQEUST['postcode'];
     }

     $how_did_you_hear_about_us = array();
     if ( isset( $_REQUEST['how_did_you_hear_about_us'] )  ) { 
$how_did_you_hear_about_us = $_REQUEST['how_did_you_hear_about_us']; 
    }

     $message = "";
      if ( isRequestSet('message' ) ) { 
$location = $_REQEUST['message'];
      }
     $apartment_price_range = array();
      if ( isset( $_REQUEST['apartment_price_range'] )  ) { 
$apartment_price_range = $_REQUEST['apartment_price_range']; 
     }

    $url = "";{
$url = $_REQUEST['url'];
}

    $property = "";{
$property = $_REQUEST['property'];
}


    if ( ($name !="") && ($number != "") && ($email != "") && ($isspam !="yes") ) { 
$to = 'name@email.com,name@email2.com';
$from = $to;
$headers =  'From: ' . $to . "\n" .
            'Reply-To: ' . $to . "\n";
$vars = array( 'name' , 'number' , 'email' , 'postcode' , 'message' ) ;
$message = "-----------\n" ;
foreach ( $vars as $v ) { 
    $value = $_REQUEST[$v];
    $message .= "$v:\t$value\n";
}
$message .= "-----------\n" ;
$message .= "\nHow did you hear about apartments?:\n"  ;
foreach ( $how_did_you_hear_about_us as $how_did_you_hear_about_us ) { 

    $message .= "$how_did_you_hear_about_us\n" ; 
}

$message .= "-----------\n" ;
$message .= "\nApartment price range:\n"  ;
foreach ( $apartment_price_range as $apartment_price_range ) { 

    $message .= "$apartment_price_range\n" ; 
}
$subject = "From: $name <$email>";
mail( $to , $subject , $message , $headers,  "-f $from" );
$confirm = true;
//redirect to the 'thank you' page
header("Location:http://website.com/file/thankyou.php");
     } else { 
$confirm = false;
    }

    ?>

最有可能是因为“发件人”和“回复收件人”字段使用了多个地址：

$to = 'name@email.com,name@email2.com';
$from = $to;

---

将其更改为使用第一封电子邮件或类似您的服务-name@you-domain name.com

仅使用一个地址发送发件人和回复收件人

$from = 'me@my-domain.com';
$headers =  'From: ' . $from . "\n" .
            'Reply-To: ' . $from . "\n";

“在下面的行中，您应该将$to字段拆分为一个数组

mail( $to , $subject , $message , $headers,  "-f $from" );

比如说

$address_array = split(",", $to);

foreach($address_array as $address)
{
mail( $address, $subject , $message , $headers,  "-f $from" );
}

这允许您使用$to字符串来包含所需数量的电子邮件

注意：如果您想跳过拆分行，只需将$to存储为一个数组即可

$to = array("name@email.com","name@email2.com");

---

将你的电子邮件部分变成一个函数。 这将使你更容易传递电子邮件地址

function email_to_user($email_address){
   $to = $email_address;

   <rest of the codes>

}

email_to_user(name1@mail.com);
email_to_user(name2@mail.com);
