Hi

You can try something like this. Now remember this is only a quick sketch to get you on the right track.

<html-code-design>

<?
// Connect to the database
mysql_connect('server', 'username', 'password');
mysql_select_db('database');

// Only when the form is submitted and id is number only
if ($_SERVER['REQUEST_METHOD'] == 'POST' && preg_match('^[0-9]+$', $_POST['infoID'])
{   $result = mysql_query('SELECT infoTitle, infoText FROM infos WHERE infoID=$_POST['infoID'] LIMIT 1');
     if (mysql_num_rows($result) > 0)
     {   $row = mysql_fetch_assoc($result);
          echo '<b>'.$row['infoTitle'].'</b><br />';
          echo $row['infoText'];
      }
      else
      {    echo 'Unknown ID';
      }
}
?>
<form name="infoForm" action="" method="post">
 <select name="infoID" size="1">
   <?
   $result = mysql_query('SELECT infoID, infoTitle FROM infos ORDER BY infoTitle');
   while ($row = mysql_fetch_assoc($result))
   {   echo '<option value="'.$row['infoID'].'">'.$row['infoTitle'].'</option>';
   }
   ?>
 </select>
</form>

<?
// Closes the database
mysql_close();
?>

I hope i've understood it correctly
