Hi..

I need to add code to check if the compound that was choose is reach the maximum value then if it is already reach theirs a notification displayed that he already gain the maximum.

the problem is..I don't know how can I check if what the user choose before run the condition.

here is my code:

Code:
<?php
  $config['BASE_DIR']  = dirname(dirname(__FILE__));   
  $config['BASE_DIR'] = $config['BASE_DIR']. '\MES PROJECT';
   define('SMARTY_DIR', $config['BASE_DIR']. '/INCLUDE/smarty/libs/');


  require(SMARTY_DIR . 'Smarty.class.php');
  $smarty = new Smarty();

  $smarty = new Smarty();
  $smarty->template_dir = $config['BASE_DIR'].  '/smarty/templates';
  $smarty->config_dir   = $config['BASE_DIR'].  '/smarty/config';
  
  $smarty->cache_dir    = $config['BASE_DIR'].  '/INCLUDE/smarty/cache';
  $smarty->compile_dir  = $config['BASE_DIR'].  '/INCLUDE/smarty/templates_c';                                                       

$con= mysql_connect('localhost', 'root', '');
 if (!$con) {
    echo 'failed'; 
    die();
 }
 
mysql_select_db("mes", $con);
 
$hostAddr = $_SERVER['REMOTE_ADDR'];

 $terminal = $hostAddr; //<-enable this in server
//$terminal = $_POST['doThis'];  //<- disable this in server
$terminal = "192.168.1.101";
switch ($terminal) {
       case "192.168.1.101" : //<< enable this in server
       //case "1" :

          $smarty->assign('machineIDdisplay', array('<Choose Machine ID>', 'B1', 'B2', 'B3', 'K1', 'K2', 'OM1', 'OM2', 'OM3', 'OM4', 'OM5', 'OM6', 'OM7'));
         
          $smarty->display('header.tpl');  // common Header
          $smarty->display('box_2.tpl');
          $smarty->display('footer.tpl');
       break;
  
}
?>
My only purpose is to avoid adding data so i need to prompt if he already reach the maximum per compound.


Thank you so much
