how to get a input field's name via PHP GET

Question

There is an example what I want to do: http://www.w3schools.com/html/tryit.asp?filename=tryhtml5_input_type_datetime

In this example, if you change the input's name, on the right side of screen (after submitting code), you'll see the changed name. And also, as you can see there is no hidden input field to get the name of input automatically. Because I searched for some answers and they say "use an hidden input field" like in this: How to access the form's 'name' variable from PHP But I need it exactly in the w3schools.

Of course this is an .asp example but I hope there is a way for this via PHP also? Thanks in advance.

@Indianer ah ok sorry. I edited. But I still have my question. Thanks. — Who Cares, Mar 06 '14 at 11:52
There is no way to do it as stated in the other question's answer. — Shlomo, Mar 06 '14 at 11:52
@Indianer then how about the example of w3? they did it how? Thanks. — Who Cares, Mar 06 '14 at 11:55
?? You cannot get the form name. w3 is getting the INPUT NAME! `bdaytime` — Shlomo, Mar 06 '14 at 11:59

To get all input field name using post method.

you can use $GET or $REQUEST instead of $POST.

$REQUEST use with both GET and POST. In php $POST is a one type of associative array.

<?php
$temp= array();
if (isset($_POST['submit']) && !empty($_POST['submit'])) {
    foreach ($_POST as $key => $val) {
        //$key is the name you wanted, and $val is the value of that input
        $temp[] = $key;
    }
}
?>

I tried that now and then tried `print_r ($temp);` but the result is nothing. – Who Cares Mar 06 '14 at 12:45
btw, i added `if (isset($_POST) && !empty($_POST)) { echo "hello";` to try, and it doesn't print "hello" to screen. – Who Cares Mar 06 '14 at 12:46
