In phprunner lookup, click create new query button to get rid of / ignore empty fields. For example in mysql:

SELECT product FROM products_table WHERE product_id <> ''


Or to make sure that query returns unique values, use select distinct

SELECT DISTINCT product FROM products_table

If you want to PREVENT duplicate values but ALLOW duplicate empty strings ,

  1. In your database make sure CAR field is not set to UNIQUE
  2. In PHPRunner Lookup Wizard, DO NOT check the "Prevent Duplicate Value" option
  3. In PHPRunner, use the following code in Add Page "Before Record Added" and Edit page " Before Record Updated" event:



global $conn;

$sql = "SELECT * FROM cars_table WHERE car ='".$values["car"]."' AND car <> '' ";

$rsExists = db_query($sql, $conn);

$data=db_fetch_array($rsExists);
if($data)

{

$message = "Car ".$values["car"]." already exists in database.";

return false;

}
