Custom stdSaveChilds Handler

jiasjias

• Create AX_DataObject_{ModuleName}.php in modulename/classes:

  			//-- save Tasks (childs)
  			$existingIds = $this->db->fetchColBySQL("SELECT id FROM democontractor_tasks WHERE Customer = " . $this->data->id);
  	        foreach($this->data->Tasks as $myTaskData) {
  	        	$myTaskData->Customer = $this->id;
  	        	$myTask = new Task($myTaskData->id);
  	        	$myTask->setData($myTaskData);
  	        	$myTask->save();
  	        }
  	        $currIds = getIdArrFromRows($this->data->Tasks);
  	        $idsToDelete = array_diff($existingIds, $currIds);
  	        if(count($idsToDelete)>0) {
  	        	$this->db->performSQLString("DELETE FROM democontractor_tasks WHERE id IN (" . join(",",$idsToDelete) . ")");
  	        }

Tweaking of AX_DataObject

• Create AX_DataObject_{ModuleName}.php in modulename/classes:

  <?php
  
  	class AX_DataObject_{ModuleName} extends AX_DataObject {
  
  		// eg. override method log to exchange DataObject logging mechanism
  		
  		public function log($DataObject,$data) {
  			syslog(LOG_WARNING, "DataObject $DataObject now reads: " . json_encode($data));
  		}
  		
  	}

• reference all your Module specific DataObject classes to AX_DataObject_{ModuleName}.
• You're done. Safe for future updates :)
