Make form selection sticky

I have a mysql table t1 and t2 In t1 I have columns id,name,and t2_id In t2 I have columns t2_id and job Then I make a html/php form that is used to populate t1. In the form there is field name where user type a name There is also a dropdownlist populated from job in t2 (relation is t2_id). I have a page where you can wiev all posts. After every posts I have a link called update. When submit update I send a $_GET to the next page wich presents a sticky form with the post related to the $_GET Again the dropdownmeny for job shall be in the update form. I want it to be sticky and I can´t solve it myself. My code is: echo "<select>"; while($rows=mysql_fetch_array($result)){ if ($x == $y) { echo "<option selected value=\"$x\"; echo "> $x</option>"; } else echo "<option value="$rows['t2_id']">$rows['t2_id']</option>"; } echo "</select>";
