I have one page where onClick of radio button I am calling one java script function which contains ajax , with the url of edit.php which has the query to return the array of chapters from table.
Now I get this chapters from database, but I want to show them in select tag of chapters. Which on first page loads has all the chapters and on click of the type(radio button) I want to show the chapters which are sorted type wise.

$stmt->bindParam("type",$_POST['val']);
$stmt->execute();
$results = $stmt->fetchall(PDO::FETCH_ASSOC);
foreach ($results as $row)
{
echo $row['title'];
}
?>
I got the result in java script variable, how can I access this in php? Or any simpler way of keeping all codes separately and make it work?
Please help thank you..
