如何使用codeigniter在邮件功能中附加pdf文件？

Question

How can I attach a PDF file in a mail using CodeIgniter?

I received mail. But I didn't find any attachment in that.

I am using the following code:

public function sendmail()
{
    $this->load->library('email');

    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '100000';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';

    $this->load->library('upload', $config);
    $this->upload->do_upload('attachment');
    $upload_data = $this->upload->data();

    $this->email->set_newline("
");
    $this->email->set_crlf("
");
    $this->email->from('[e-mail]');
    $this->email->to($this->input->post('to'));
    $this->email->subject($this->input->post('subject'));
    $this->email->message($this->input->post('message'));


    if ($this->email->send()) {
        echo "Mail Send";
        return true;
    } else {
        show_error($this->email->print_debugger());
    }
}

Use $this->email->attach(); this Enables you to send an attachment

$this->email->attach('path_to_file');

You can also use a URL like this :

$this->email->attach('http://example.com/filename.pdf');

Should be like this :

 $pdf_file_path = FCPATH.'your path';

 $this->email->set_newline("
");
 $this->email->set_crlf("
");
 $this->email->from('[e-mail]'); 
 $this->email->to($this->input->post('to')); 
 $this->email->subject($this->input->post('subject'));
 $this->email->message($this->input->post('message'));

 $this->email->attach($pdf_file_path);
