Here's the code:

<?php // operator Page

$conf = new Dbconf();
$dbURL = $conf->get_databaseURL();
$dbUName = $conf->get_databaseUName();
$dbPword = $conf->get_databasePWord();
$dbName = $conf->get_databaseName();
$nameOfDbWithCustomers = $conf->get_tableName('customer');

if(isset($_REQUEST[session_name()]))
{
   session_start();
}
else

I want to get value of checked checkbox from table when user press on "send" button. How can I do that?

You should assign a value for checkbox in HTML code

Active: <input type='checkbox' name='Active' value='1'> 

and then if the checkbox is checked it contains assigned value in POST otherwise you have to set when checkbox is unchecked

$active = isset($_POST['Active']) && $_POST['Active']  ? "1" : "0";

From $_POST:

See also var_dump().

All values of checked checkboxes should be in $_POST['cbname3'].
