我目前正在使用php mysql基本系统,该系统将通过功能上的复选框将电子邮件从数据库发送给多个收件人.

如何使用“检查所有功能”向那些收件人发送电子邮件？

这是我的phpMailer代码,可以正常工作

<?php
require("class.phpmailer.php");
include("class.smtp.php");
$mailer = new PHPMailer();
$mailer->IsSMTP();
$mailer->Host = 'ssl://smtp.gmail.com:465';
$mailer->SMTPAuth = TRUE;
$mailer->Username = 'myemail@gmail.com';
$mailer->Password = 'mypassword';
$mailer->From = 'myemail@gmail.com';
$mailer->FromName = 'Admin';
$mailer->Body = 'TEST EMAIL';
$mailer->Subject = 'This is the subject of the email';
$mailer->AddAddress('myrecipient@yahoo.com');
if(!$mailer->Send())
{
echo "Message was not sent<br/ >";
echo "Mailer Error: " . $mailer->ErrorInfo;
}
else
{
 echo "Message has been sent";
}
?>

我当前在系统中使用的另一个示例代码,用于通过复选框功能从数据库中删除用户：

<?php
/*Check Box Commands*/
$id=$row_notification['user_id'];

if(isset($_POST['Delete'])) {
$checkbox = $_POST['checkbox'];
mysql_select_db($database_connection_ched, $connection_ched);
$id=$row_notification['user_id'];

for($i=0;$i<count($checkbox);$i++)
        {
            $delete = "DELETE FROM tb_user WHERE user_id=$checkbox[$i]";
            mysql_query($delete,$connection_ched);
        }
$result2 = mysql_query($delete);

    if($result2)
    {
    echo "<script language='javascript'>alert ('Successfully Deleted');</script>";
    echo "<meta http-equiv=\"refresh\" content=\"0;URL=notification.php?\">";   }
}
/*End of Checkbox Commands*/
?>

解决方法:

您可以从那里的删除代码中使用一些逻辑,但是也可以通过只调用一次数据库来获取信息来改进它：

<?php
require("class.phpmailer.php");
include("class.smtp.php");
$mailer = new PHPMailer();
$mailer->IsSMTP();
$mailer->Host = 'ssl://smtp.gmail.com:465';
$mailer->SMTPAuth = TRUE;
$mailer->Username = 'myemail@gmail.com';
$mailer->Password = 'mypassword';
$mailer->From = 'myemail@gmail.com';
$mailer->FromName = 'Admin';
$mailer->Body = 'TEST EMAIL';
$mailer->Subject = 'This is the subject of the email';

// get checkbox ids posted to us
$checkbox_ids = $_POST["checkbox"];

// get email addresses from db based on checkboxes posted to us
$query = "select email from tb_user where user_id in(".join(",",$checkbox_ids).")";

// connect to db and run query
mysql_select_db($database_connection_ched, $connection_ched);
$result = mysql_query($query);
while( $data = mysql_fetch_assoc($result) )
{
    // make SURE we are not sending this to each and every recipient incrementally.
    // alternately, you can use $mailer->ClearAllRecipients(); <-- this will clear cc and bcc as well
    $mailer->ClearAddresses();
    // send it to THIS user...
    $mailer->AddAddress($data["email"]);


    print ($mailer->Send()) ? "Message sent to: " : "Message <b>not</b> sent to: ";
    print $data["email"]."<br />\n";
}

?>
