Populate Querystrings from MySQL query in WordPress

Here’s the situation :

I would like, either with querystrings or with another way, to populate a Ninja Forms form with values from a MySQL query to a database table.

Here is how it works for now :

<?php
/**
* Template Name: Key Editor
*
* The template for displaying the Key Editor
*
* @package QSI
*/

get_header();
?>
<?php  

$fetchKEY = '12345'; 

global $wpdb;
$results = $wpdb->get_results("SELECT keylic, keycie from pos_keys where keylic = '12345'", OBJECT);
$result=mysql_query($results);
?>
<div class="container">
<form name="form" method="GET" action="../cle-best">
  Keyfield <input type="text" maxlength="10" name="keyinput" value="<?php echo $fetchKEY ?>">
<input type="hidden" maxlength="40" name="cie" value="<?php echo $result["keylic"] ?>">
<input type="submit" value="submit" id="submit"/>
</form>
</br>
</br>
<?php
get_footer();
?>

Now the problem is that my link will only display link.php?keyinput=12345&cie=

So now it gives a problem to my functions.php script which is :

function my_filter_function( $data, $field_id ){

  if( $field_id == 12 ){
    $data['default_value'] = $_GET['keyinput'];
  }
  if( $field_id == 18 ){
    $data['default_value'] = $_GET['cie'];
  }
  if( $field_id == 10 ){
    $data['default_value'] = '1';
  }
  return $data;
}
add_filter( 'ninja_forms_field', 'my_filter_function', 10, 2 );

Do you have any solution? Or even, if possible, a way to populate the form with a query without having to manage querystrings?

Thank you!
