PHP - Call Function From Class By String.

Hi I have a table class and functions I want to call in another function but can't get it working. Some help will be very welcome.

It seesm that the new table class is not working in this function if I pass the values to it, I have tested the class, it does get the post values I post to it so $_POST['id'] are being received as well as all the other $_POST's but the table class and find function is not working, it works fine if I don't put it in a function..

function edit() {
   
   if (isset($error)){ $error.="Please fix the error(s) above";}
   else {

      if ($_POST['id'] <> "") { 
                   
         $update =& new table($db, 'publisher');

         $update->find($_POST['id']);
         $update->name       = $_POST['name'];
         $update->url        = $_POST['url'];
         $update->contact    = $_POST['contact'];
         $update->address    = $_POST['address'];
         $update->phone        = $_POST['phone'];
         $update->email        = $_POST['email'];
         $update->save();

         $error = "The Publisher has been edited";   
                }
   }
  }

Im working with php 5.1.6. With xampp 1.5.14. Im also working on a stock application. If I want to say add stock product (add_stock.php) this error is generated on screen. It seems to refer to a function in ump.class.php   Here we go, ump.class.php

now who can tell me what is wrong with the function filter_var() method on line 186 in ump.class.php?  

If a class has a constructor but also has a static method, if I call the static method does the constructor run so that I can use an output from the constructor in my static method?

I can call the following function successfully as a single php program

  // Acknowledge and clear the orders
   function ack($client, $merchant, $id) {
         $docs = array('string' => $id);
         $params = array('merchant' => $merchant, 'documentIdentifierArray' => $docs);
         $result = $client->call('postDocumentDownloadAck', $params);
         return $result;
         }
with

   $result = ack($t, $merchant,'2779540483');

successful output

    [documentDownloadAckProcessingStatus] => _SUCCESSFUL_
    [documentID] => 2779540483

I'm trying to figure out how to call this function as an object from another program.

Trying the following gives error  ***Call to a member function call() on a non-object***

  function postDocumentDownloadAck($t, $merchant, $id) {
     $this->error = null;
     $docs = array('string' => $this->id);
     $params = array('merchant' => $this->merchant, 'documentIdentifierArray' => $docs);

 **  I've tried the following which does nothing
     $result = $this->soap->call('postDocumentDownloadAck', $params);

** I've tried the following   -  which gives error "Call to a member function call() on a non-object"
     $result = $this->t->soap->call('postDocumentDownloadAck', $params);

     if($this->soap->fault) {
        $this->error = $result;
        return false;
     }

     return $result;
  }


***

calling program snippet for above function
   $merchant= array( "merchant"=> $merchantid, "merchantName" => $merchantname, "email"=> $login, "password"=> $password);
   $t = new AmazonMerchantAPI($merchantid, $merchantname, $login, $password);
   $documentlist= $t->GetAllPendingDocumentInfo('_GET_ORDERS_DATA_');
   $docid = $documentlist['MerchantDocumentInfo'][$i]['documentID'];
   $docs = array('string' => $docid);
   $ackorders = $t->postDocumentDownloadAck($t, $merchant,$docs);

Any ideas of what I'm doing wrong are greatly appreciated.
