You must assign a value to the checkbox in the HTML code

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

and then, if the checkbox is checked, it contains the assigned value in POST, otherwise you must set when the checkbox is unchecked.

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

All values ​​of checked flags must be in $_POST['cbname3'] .
