php自我提交和记录更新

I have multiple buttons on a single page. I need when I click a button that the same page reloads, but a counter and name of button clicked be updated. And as many times I do that, the list of clicked buttons and name of buttons should be maintained. Something like a visitor of site concept and counter.

e.g.

Button1 (value "Milk") Button2 (value "Cereals") etc...

Now pressing any of the buttons above will be like:

List: Item1: Button 1 - value of button item2: .... etc

I will have then a submit button that once am done with adding the items I need to list, I click and go to review what I selected...

Any idea how this can be done via php only without JS?

Thanks, and sorry if not so clear but I tried my best

    You can create a form that submits to itself, in conjunction with sessions that retain the data for as long as you want it.

    <?php
session_start();

if(isset($_POST)):

foreach ($_POST as $key => $value) {
    $_SESSION[$key] = (isset($_SESSION[$key]) ? $_SESSION[$key]+= 1 : 1);
}
endif;
?>
<!doctype>
<html>
<head>
</head>
<body>
<form method='post' action=''>
<input type='submit' name='milk' value='Milk'>
<input type='submit' name='cereals' value='Cereals'>
</form>
Milk: <?php echo $_SESSION['milk']; ?>
Cereals: <?php echo $_SESSION['cereals']; ?>
</body>
</html>
