Answer 1

You question is not clear what actually you need. But if you want all values from database than you need to modify your controller as:

$data = $this->front->ven_coupon($number);
if(count($data) <= 0){
  echo "not valid"; // print error
}
else{
  print_r($data); // print all data
}

This is basic example you can store them into variable and pass into load view.
