php mysql编辑表格将表格的字段恢复为原始值

I have a form for editing a table in the database, when I edit a table using the forms it do nothing and give no errors. But when I edit it from phpMyAdmin it works, but if I edit it back using the php form it reverts the fields values to it's original values that I gave it in the add form. I'm using pdo class to connect to the mysql database.

Here is the php code to edit the table, it's kinda miss I know :/, note that I store the form values in arrays because I have a for loop in creating the form so it give fields for each employee and of course I change the name of the fields using a prefix:

<?php
if((isset($_GET['action'])) and ($_GET['action'] == 'edit')){
   //Get employees info
        $employees = PDO_FetchAll("select * from employees");

        //echo "<script>alert('AA');</script>";
        //Initial values
        $official_days_e = array();
        $official_vacations_e = array();
        $attendance_days_e = array();
        $present_days_e = array();
        $vacations_e = array();
        $vacations_record_e = array();

        $table_nameE = $_POST['table_name'];

        //echo "<script>alert('BB');</script>";
        foreach($employees as $employee){
            $official_days_e[] = $_POST[$employee['emp_id'].'_official_days_e'];
            $official_vacations_e[] = $_POST[$employee['emp_id'].'_official_vacations_e'];
            $attendance_days_e[] = $_POST[$employee['emp_id'].'_attendance_days_e'];
            $present_days_e[] = $_POST[$employee['emp_id'].'_present_days_e'];
            $vacations_e[] = $_POST[$employee['emp_id'].'_vacations_e'];
            $vacations_record_e[] = $_POST[$employee['emp_id'].'_vacations_record_e'];
        }

        //echo "<script>alert('$official_days_e[1]');</script>";

        //Edit the values in the DB
        $countt = 0;
        foreach($employees as $employee){

            $empl_id = $employee['id'];
            $official_dayss_e = $official_days_e[$countt];
            $official_vacationss_e = $official_vacations_e[$countt];
            $attendance_dayss_e = $attendance_days_e[$countt];
            $present_dayss_e = $present_days_e[$countt];
            $vacationss_e = $vacations_e[$countt];
            $vacations_recordss_e = $vacations_record_e[$countt];

            $countt = $countt+1;

            $attendance->query("update $table_nameE set
            `official_days` = $official_dayss_e,
            `official_vacations` = $official_vacationss_e,
            `attendance_days` = $attendance_dayss_e,
            `present_days` = $present_dayss_e,
            `vacations` = $vacationss_e,
            `vacations_record` = $vacations_recordss_e") or die($attendance->errorInfo());

        }
        //echo "<script>alert('$countt');</script>";
        //echo "<script>alert('Done');</script>";
        echo "<script>playSound('js/sounds/sound1.ogg');</script>";
        echo "<script>$.miniNoty('Done', 'success');</script>";
        //echo "<script>setTimeout(function(){ window.location='attendance.php'; }, 1200);</script>";
}

The code works with no errors. Note that the add form have almost the same code, could it be a ram storing problem ?, I tried to change the variables names but didn't help.
