i am wondering on how to make a combo box that query without button
<select name="item">
<option value"item1">item1</option>
<option value"item2">item2</option>
</select>
for example they choose item1, the system should select item1 from table mysql_query("select * from table WHERE item='$_POST[item]'");
so the result will be:
ID | item
1 | item1
