Question

I have two fields one for link and one for file upload in form, how do i add only one of those i.e. either link or file in database,
Sorry for any wrong code and methods, I am a newbie here and this is my first question in stack overflow. Hope you all help me out.
My Controller is
public function add_scrolllink()
{
$this->form_validation->set_rules('stitle','File Title','trim|required');
$this->form_validation->set_rules('slink','File Link','trim|required');
if(empty($_FILES['sfile']['name']))
{
$this->form_validation->set_rules('slink','File Link','required');
}
if($this->form_validation->run() == FALSE)
{
$this->load->view("add_scrolllink");
}
else
{
$slink_id = $this->input->post('stitle');
$slink_files = $this->input->post('slink');
$config['upload_path'] = './assets/uploads/';
$config['allowed_types'] = 'pdf|docx|doc';
$config['max_size'] = 9000;
$this->upload->initialize($config);
$this->load->library('upload',$config);
if(!$this->upload->do_upload('slink'))
{
$msg1 = $this->upload->display_errors();
header("Location:".base_url()."news/add_scrolllink?msg1=$msg1");
}
else
{
$output = $this->upload->data();
$file2 = $output['file_name'];
$this->load->model('mpages');
$output1 = $this->mpages->add_scrolllink($slink_title,$file2);
if($output1)
{
$msg = "Scrolling Link added successfully!";
header("Location:".base_url()."news/scrolllink_list?
msg=$msg");
}
else
{
$msg1 = 'Scrolling Link add failed. Try again!';
header("Location:".base_url()."news/add_scrolllink?
msg1=$msg1");
}
}
}
//My View is
<form action="<?php echo base_url(); ?>news/add_scrolllink" method="post"

you have use jquery to get input box value using this code and set some condition
$('#slink-id').val(); // set link field input box id
$('#slinkFile-id').val(); //set upload file field id
if($('#slink-id').val() != '' && $('#slinkFile-id').val() == ''){
// setread only your file field
}else{
// set read only link field
}
