Brand new to the forum, and have only been working with HTML, PHP, & MySQL for about 3 months. I've run into an issue I can't seem to figure out how to work around. I want to have two select boxes, that are dependent on one another. For Example: First box lists types of games: RPG LARP Board Game Miniatures CCG The second box displays game names of the type selected above. I have a MySQL table setup for the second box. To be honest I kinda already have it working... with one small but MAJOR glitch. I select the first box and the page submits using onchange='this.form.submit()'. When the page reloads the first select box reverts back to it's default setting, but the second box does correctly filter & show the content based on the selection that was made in the first box. My Question: How do I set this up so that the first box displays the user selected setting while also passing the $_POST information to the second box? My Code: <table> <tr> <td width=50%> Game Type: </td> <td width=50%> <form name='game_type' action='event_submit.php' method='post'> <select name='game_type' align=center onchange='this.form.submit()' style="width:150px;margin:5px 0 5px 0;"> <option value=''>Chose a Game Type</option> <option value='RPG'>RPG</option> <option value='LARP'>LARP</option> <option value='Board Game'>Board Game</option> <option value='CCG'>Collectable Cards & Games</option> <option value='Miniatures'>Miniatures</option> </select> </form> </td> </tr> <tr> <td width=50%> Game System: </td> <td width=50%> <?php $game_type = $_POST['game_type']; echo "$game_type"; if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("DrowCon", $con); $result = mysql_query("SELECT * FROM Games WHERE Type='$game_type' ORDER BY System ASC"); echo "<form name='game_system' action='event_submit_form.php' method='post'>"; echo "<select name='game_system' align=center style='width:150px;margin:5px 0 5px 0;'>"; echo "<option value=''>Chose a Game System</option>"; while($row_game = mysql_fetch_array($result)) { echo "<option value=''>".$row_game['System']."</option>"; } echo "</form>"; mysql_close($con); ?> </td> </tr> </table>
