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

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();开发者_如何学编程

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.

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