Update and Save a record programmatically in vTiger - vtiger

Question

Currently I'm trying to change the 'Assigned To' user for a lead to the current user whenever a user enters the lead details screen.
I have the following code:
function checkPermission(Vtiger_Request $request) {
$moduleName = $request->getModule();
$recordId = $request->get('record');
$recordModel = Vtiger_Record_Model::getInstanceById($recordId, $moduleName);
$recordModel->set('assigned_user_id',$current_user->id);
$recordModel->save();
...
return true;
}
The problem is, instead of saving the current record with a new assigned user, vTiger duplicates this record into a new record and saves it with the current user as a new assigned user.
Working on vTiger v6.2.0

Answer 1

You need to set mode is edit to recordModel before save
$recordModel->set('mode','edit');

Answer 2

Try something like this:
$recordModel= Vtiger_Record_Model::getInstanceById($recordId,$moduleName);
$recordModel->set(my_fields, my_new_value);
$recordModel->set(my_fields2, my_new_value2);
$recordModel->set('mode', 'edit');
$recordModel->save();

Answer 3

Tray with event Handler;
create a file: /modules/yourmodulename/handlers/RecordUpdater.php
then put the code below in your file RecordUpdater.php :
require_once 'include/events/VTEventHandler.inc';
class yourmodulename_RecordUpdater_Handler extends VTEventHandler {
function handleEvent($eventName, $data) {
global $adb;
$currentUserModel = Users_Record_Model::getCurrentUserModel();
$module = $data->getModuleName();
if ($eventName === 'vtiger.entity.beforesave' AND $module === "yourmodulename") {
require_once 'modules/yourmodulename/yourmodulename.php';
$currentUserId = $currentUserModel->getId();
$data->set('assigned_user_id', $currentUserId);
}
}
}
finally don't forget to insert in vtiger_eventhandlers table:
INSERT INTO `vtigercrm`.`vtiger_eventhandlers` (
`eventhandler_id` ,
`event_name` ,
`handler_path` ,
`handler_class` ,
`cond` ,
`is_active` ,
`dependent_on`
)
VALUES (
NULL , 'vtiger.entity.beforesave', 'modules/yourmodulename/handlers/RecordUpdater.php', 'yourmodulename_RecordUpdater_Handler', NULL , '1', '[]'
);
then increment vtiger_eventhandlers_seq with 1
that's it :)
I hope, that helps you
