Codeigniter: Email attachment of last emails not cleared while sending multiple emails in loop

Question

My code sends multiple emails in loop with attachment,

Problem is attachments of last(previous all) emails get attached to next email.

ex. suppose 3 emails in database with 1 attachment in each(a1.pdf, a2.pdf, a3.pdf) then, it sends email with attachment as

email 1:

attachment :a1.pdf

email 2:

attachment :a1.pdf, a2.pdf

email 3:

attachment :a1.pdf, a2.pdf, a3.pdf

I am using codeigniter framework.

My code is (this code is called in loop)

. . .

$this->email->subject($item->subject);

        $this->email->message($message);
        $attachments='';
        if(strlen($item->attachment) > 5)
        {
            $attachments = explode(',', $item->attachment);
            foreach($attachments as $attachment)
            {
                if(strlen($attachment)>5)
                $this->email->attach(FCPATH . 'attachments/' . $attachment);                    
            }                

        }

      $this->email->send();

. . .

found solution: $this->email->clear(TRUE); – anils Aug 13 '11 at 13:54 — anils, Aug 13 '11 at 13:54

You need to reset it in CodeIgniter.

At the end of the loop add:

$this->email->clear(TRUE);

This resets all email variables including the attachments, allowing you to create a new mail.

This works but in my case, it does not attached file on the last loop. – Kentot Nov 20 '15 at 01:24
Upvoted as correct answer as clear() requires a TRUE boolean to clear the attachments. – Tobe_Sta Feb 27 '19 at 23:44

You need to use $this->email->clear(); to clean out the variables set within the loop. Read the manual.

Remember to include TRUE when calling clear() in order to remove any current attachments. – Tobe_Sta Feb 27 '19 at 23:43
