javascript - Get description from the second drop down menu -

-

i have form 2 select menus ! first 1 "cat" loaded automatically database. second 1 "soucat" loaded automatically using javascript when item selected first select menu.

the problem can't description second select menu send via $_post!

<form method="post" action="" oninput=""> <label>     <select name="cat" id="cat" onchange="getcat()">         <option value="-1">categories</option>         <?php         /* fill in drop down menu database */         ?>            </select> </label>  <label id="souscat">     <select id="soucat" name="soucat">         <option value='-1'>subcategories</option>      </select> </label>  <span class="fieldd" id="searchformm">     <input type="text" name="searchterm" id="searchterm" placeholder="product find ?" />     <button type="submit" class="monboutton" >find !</button> </span>  </form>

now, i've set code store informations contained in form :

<?php                                            unset($cat);  if(isset($_post['cat'])) {$cat = explode('|', $_post['cat']);} else      $cat="";  unset($soucat);  if(isset($_post['soucat'])) {$soucat = mysql_real_escape_string($_post['soucat']);} else      {$soucat=""; echo "soucat still empty";}  unset($searchterm);  if(isset($_post['searchterm'])) {$searchterm =  mysql_real_escape_string($_post['searchterm']);} else      $searchterm=""; ?>

and test , see :

echo  "the category is: ".$cat[1]."<br>"; echo  "the sub category is: ".$soucat."<br>"; echo "the searchterm is: ".$searchterm."<br>";

$cat[1] , $searchterm containing descriptions must contain. $soucat empty! don't know how deal problem.

think problem missing s :-) call $soucat , $souscat. post soucat , souscat.

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
