JQuery自动完成 - 从2个搜索词中检索数据

Question

我正在尝试捕获第二个术语以显示结果，因此textbox1具有自动完成功能，textbox2具有简单输入 - 这是自动完成并在1个术语上返回值的代码...

//connect to your database

$term = trim(strip_tags($_GET['term']));//retrieve the search term that autocomplete sends

$qstring = "SELECT description as value,id FROM test WHERE description LIKE '%".$term."%'";

$result = mysql_query($qstring);//query the database for entries containing the term

while ($row = mysql_fetch_array($result,MYSQL_ASSOC))//loop through the retrieved values
{
    $row['value']=htmlentities(stripslashes($row['value']));
    $row['id']=(int)$row['id'];
    $row_set[] = $row;//build an array
}

echo json_encode($row_set);//format the array into json data

我需要这样的东西

$term = trim(strip_tags($_GET['term']));
$term2 = trim(strip_tags($_GET['term2']));

$qstring = "SELECT description as value, lastname, id FROM test 
            WHERE description LIKE '%".$term."%'" AND lastname LIKE '%".$term2."%'";

etc...

有人可以帮忙吗？
