"Description:
We need a skilled PHP + jQuery/AJAX developer to fix the autocomplete autosubmit function in our accounting web application.

Current Issue:

The <form id="Ledajax-form" class="autosubmit" method="POST" action="/Accounting/[login to view URL]"> should automatically POST values via the jQuery autoSubmit function (defined in [login to view URL]).

However, the POST values are not being passed correctly to [login to view URL], resulting in failed database updates ($col,$val,$w_col,$w_val are empty).

Steps to Reproduce:
1. Login: [login to view URL]
(see [login to view URL]).

2. Navigate to Accounting: [login to view URL]
([login to view URL]).

3. Select the period: 0 : 2024Y10M01D ～ 2025Y09M30D from the dropdown ([login to view URL]).

4. Press DONE button to load the list ([login to view URL]) ([login to view URL]).

5. Edit any text box inside <form id="Ledajax-form" ...> ([login to view URL] : line 268) ([login to view URL]).

6. The autosubmit script (at [login to view URL] : line 365) triggers, but POST values are lost before reaching ajax-update.php.

7. Error alert: UPDATE accountant SET ='' ->|->|WHERE ='' ([login to view URL]) ([login to view URL]).

What We Expect:
-Debug and fix the AJAX autosubmit so that correct POST values are passed to ajax-update.php.
-Ensure $col, $val, $w_col, $w_val are properly received and database updates succeed.
-Keep existing functionality intact.
