Question

I’m currently working on a php mysql base system that will send email to multiple recipients from database with checkbox functionally.

How can i send email to those recipient using check all functionality?

Here is my phpMailer code and is working fine

<?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 = '[e-mail]';
$mailer->Password = 'mypassword';
$mailer->From = '[e-mail]';
$mailer->FromName = 'Admin';
$mailer->Body = 'TEST EMAIL';
$mailer->Subject = 'This is the subject of the email';
$mailer->AddAddress('[e-mail]');
if(!$mailer->Send())
{
echo "Message was not sent<br/ >";
echo "Mailer Error: " . $mailer->ErrorInfo;
}
else
{
 echo "Message has been sent";
}
?>

another example code i’m currently using in the system to delete a user from database with checkbox functionality:

<?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*/
?>

You can use some of your logic from the delete code you have there, but you can improve that too by just making one call to the db to get your info:

<?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 = '[e-mail]';
$mailer->Password = 'mypassword';
$mailer->From = '[e-mail]';
$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";
}

?>
