ObjectExpected???

I have a selection box, that on select i want to call a function called loadData(), see below:

<SELECT NAME="secondChoice" ID="secondChoice" ONCHANGE="loadData();" > 

Code (markup):

And below is a copy of my function:

  function loadData()
  {
     require_once('./mysql_connect.php');
     $partno = $_POST['secondChoice'];
     $query = "SELECT * FROM systemconfig_generic WHERE $partno = partno";
     $result = @mysql_query($query);
     if($result)
     {
        echo 'Part No Found: ' .$partno . '<BR>';
     }
     else
     {
        echo 'No Part No Found <BR>';
     }
  }

PHP:

However, when i select an item from the selection box, i keep getting Object Expected error...i have no idea what the means??

Please help.

 

You cant call PHP functions as Javascript....

 

Is there such a thing as a php function?? If not, how would i go about executing the php stuff on selection change??

 

You can't... You must reload the page...
Or use AJAX.

 

OK how about this question:
I have a selection box, on change i want to do some php stuff...how would i go about doing this???

thanks for your help in advance.
