Getting name of check boxes even if some of them are null

[alirezaok]

hi

i have a form.
my form has a lot of check boxes.
by ever refresh new check boxes will be create.
i don have name of check boxes and their values.

i use of :

foreach ($_POST as $key => $value)
    {
echo "$key : $value";
echo "<br>";
}

in action page to getting name of checkboxes and their values

Problem is this script getting names and values only checkboxes that cheked.

i need to getting names of all of checkboxes from form page even if their values is empty (they are not checked).

is there any way?

The browser will only transmit checked checkboxes in the form data. One work-around is to add a hidden field with the same name before the checkbox with its value being something to indicate it's unselected. That way the corresponding checkbox's value will take precedence and be sent if it is checked, otherwise you'll get the value of the hidden field of the same name.
