This will display a two-row table in a form of HTML, and in the end of the row there is a decline button (see image below).

The question is, where should I put this:
if (isset($_POST['Edit'])) {
$delete = $a;
echo $delete;
}
so that if I click the first decline button, it will display "a", and if I click the second one it will display "ako"?
<button>element, then put the value of$ato the value property of the<button>, that way you can pass the value to the POST<form></form>should be inside your<th></th>, not the other way around.
