How to attach cv to notification emails

Hi,

I have used the code below to receive attachment along with the notification emails. I have found this code snippet on one of the other related topic. I have used the code inside my theme fucntions.php file but I am still not receiving CV attachments with the email. Could you help me with this please. Thank you.

/**
 * Job Board stuffs

// Filter to Attach HR Resume
add_filter('sjb_hr_notification_attachment', 'custom_code_for_hr_resume_attachment', 20, 2);
add_filter('sjb_admin_notification_attachment', 'custom_code_for_hr_resume_attachment', 20, 2);

function custom_code_for_hr_resume_attachment( $resume_path, $post_id ){

    $fileAttachment = get_post_meta($post_id, 'resume', TRUE);
    $filePath = parse_url($fileAttachment, PHP_URL_PATH);
    return array(get_home_path() . $filePath);
}

Kind Regards,

Bikash
