Having problem with JeasyUI project

I try to make a exe of JeasyUI CRUD (http://www.jeasyui.com/tutorial/app/crud.php) demo. It loads the data successfully. But updating aur adding data to database is not working. It through some error. I already set LocalMirror=0, OverwriteLocalMirror=0, and DeleteDatabaseFiles=0 in pms_config.ini. I follow the instructions of https://www.exeoutput.com/mysql.php. Could anyone please help?

What error are you getting? Is it some PHP error?

PHP Notice: Undefined index: id in update_user.php in line 3

I got this error message when try to update a row. In the line 3 of update_user.php is $id = intval($_REQUEST['id']);

And the error messages for saving a new row are:
PHP Notice: Undefined index: firstname in save_user.php in line 3
PHP Notice: Undefined index: lasttname in save_user.php in line 4
PHP Fatal error: Maximum execution time of 30 seconds exceeded in save_user.php

The lines 3 and 4 in save_user.php is as follows:
$firstname = $_REQUEST['firstname'];
$lastname = $_REQUEST['lastname'];

But if I run the php project normally in the browser with server2go it works fine with out any error.

So for some reason it looks like some fields are not passed correctly. Are you using the Chromium or Trident engine?

I am using the Chromium engine.
