Can't attach file dynamically

Hi guys,

I’ve been trying to attach files dynamically without any success. Here’s what I’ve tried:

add_action('wpcf7_before_send_mail','send_pdf');
function send_pdf( $cf7 ) {
        $submission = WPCF7_Submission::get_instance();
        $submission->add_uploaded_file('pdf', '../path/to/uploads/test.pdf');
}

I’ve also tried:

add_filter( 'wpcf7_mail_components', 'mycustom_wpcf7_mail_components1', 10, 2 );
function mycustom_wpcf7_mail_components1( $components, $form ) {
        $components['attachments'] = array("../path/to/uploads/test.pdf");
        return $components;
}

Any ideas? Thanks!
