hey guys i was wondering on how i can get info from my database from a select box.

 

like i tryed this with no luck:

 

<?
require "config2.php";

$connection = mysql_connect($dbhost, $dbusername, $dbpass);
	$SelectedDB = mysql_select_db($dbname);

$cat=$_GET['cat'];
$QQQ1 = mysql_query(" SELECT id, pic  FROM $cat ");
if(!$QQQ1) die(mysql_error());
$err = mysql_num_rows($QQQ1);
if($err == 0) die("No matches met your criteria.");
?>

<body>
<form id="form1" name="form1" method="post" action="">
  <label>
  <select  onchange="reload(this.form)" name="cat" id="cat">
    <option value="ABS">ABS</option>
    <option value="ARMS">ARMS</option>
  </select>
  </label>
</form>

<?
while ($line = mysql_fetch_array($QQQ1)) {
echo "<option value=\"$line[id]\">$line[pic] </option>";

}?>
</body>
</html>

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

 

im shure it's because it is executing the query before i chose the categorie?
