PHPmailer - Multiple sending of e-mail

Question

I am sending emails using PHPmailer. As of now, I am successful in sending email to one address. Now, I want to send multiple emails in just one click.

Within your loop, create a clone of the $mail object - before you add the recipient and attachment - then use the clone to send the email. The next loop iteration will create a new clone free of the previous address and attachment:

while($row = mysql_fetch_assoc($p_address)) {

    $cloned = clone $mail;

    $cloned->AddAddress($row['email_address']);

    // add attchment to $cloned, etc.

    if ( $cloned->send() ) { /* etc */ }

    unset( $cloned );

}

This will "clear" your per-iteration changes (like address, attachment, etc) without you having to reenter config properties (like, from, host, etc.)

Addendum:

Your attachments will likely be all the same because you're not fetching new results for these lines (within your loop):

$input=addslashes($_POST['depchair']);

$control = "select control_no  from sa_student where schoolyear = '$input'";

if ($ctrl=mysql_query($control)) {

    $ctrl_no = mysql_result($ctrl, 0);

    $mail->AddAttachment("fpdf/pdf_reports/document/".$ctrl_no.".pdf");

}

$ctrl_no will always return the same result because (I'm assuming) $_POST['depchair'] does not change - thus $input, $control, $ctrl, and $ctrl_no all remain (effectively) the same for each loop. You need to find whatever it is your actually intend to be the $ctrl_no for each loop - right now you're using the same one over and over.

The following query could probably help:

// replace
// $email = "select email_address  from sa_student where schoolyear = '$input'";

// with:
$students_query = "select email_address, control_no from sa_student where schoolyear = '$input'";

// then
// if ($p_address=mysql_query($email)) {
// while($row = mysql_fetch_assoc($p_address)) {

// becomes
if ( $students=mysql_query($students_query) ) {
while ( $row = mysql_fetch_assoc( $students ) ) {

// so that finally, etc
$cloned->AddAddress($row['email_address']);
$ctrl_no = $row['control_no'];

This pulls both the student email address and their control_no in the same query, making sure they stay associated with each other through the loop. You can then get rid of the second mid-loop query, since all the results you need were pulled in the first out-of-loop query. The above isn't all the code you need to change, just the critical parts.

After you send an email $mail->Send(), execute this:

$mail->ClearAllRecipients();

in your while loop.
So your basic while loop structure looks like this:

while($row = mysql_fetch_assoc($p_address)){

    $mail->AddAddress($row['email_address']);
    $mail->AddAttachment("fpdf/pdf_reports/document/".$ctrl_no.".pdf");
    $mail->send();
    $mail->ClearAllRecipients(); 
    $mail->ClearAttachments();   //Remove all attachements

}
