Hi jorge,

I give you anotrhe aproach:

If you apply an object model  in your case you can simplify the main object
transaction. For Example:

class transaction  {
  var $_client;  // to manipulate this object use the client class
  var $_vendedor; // to manipulate this object use the vendedor class
  var $_items; // to manipulate this object use the item class
  var $_taxes; // to manipulate this object use the taxes class

  // declarate your transactions functions 
  function create($client_data,$vendor_data,$items_data,$taxes_data) {
     $this->_client = new client;
     $this->_vendor = new vendor;
     $this->_items = new items;
     $this->_taxes = new taxes;
      
     $this->_client->get($client_data);
     $this->_vendedor->get($vendedor_data);
     $this->_taxes->get($taxes_data);
     $this->_items->get($items_data);
 
     // Now you storage into the data base you transaccion values
     //eg 
     
     $sql = "insert into transaccion values
('{$this->_client[id]}','{$this->_vendedor[id]}','{$this->_items}','{$this->_taxes}')";

    // and run the sql

  }//end function create

}

class client{
   var $_client; 
    
   // I use an  single var to store data object. I return an array from data
base witn the user
   //atributes or false on query crash 

   function create($client_data){
   }

   function get($get_client_parameters){
   }

   function update($client_data){
   }

   function remove(){
   }

}


class vendedor{
   var $_vendedor; 
    
   function create($vendedor_data){
   }

   function get($get_vendedor_parameters){
   }

   function update($vendedor_data){
   }

   function remove(){
   }

}


class items{
   var $_items; 
    
   function create($items_data){
   }

   function get($get_items_parameters){
   }

   function update($items_data){
   }

   function remove(){
   }

}

class taxes{
   var $_taxes; 
    
   function create($taxes_data){
   }

   function get($get_taxes_parameters){
   }

   function update($taxes_data){
   }

   function remove(){
   }

}


This is an sample object model of your case. Take a look, and good luck my freind!!!
