D*mn. It's either senility or complacency that got me here.

I wrote "post", but I meant "get". Mea culpa.

FWIW, I almost never write parameterized "get" pages; I mostly use POST 
unless I absolutely have to use GET. P'haps that's what got me off-track.

I meant:

  <form method="get" action="page2.php?fruit=papaya&veggies=potato">
  <input type="submit">
  </form

I meant:

PHP will set the $_GET[] array with the key/value pairs:
  $_GET['fruit'] will be set to "papaya", and
  $_GET['veggies'] will be set to "potato"

I meant:

If the parameter is not supplied, PHP will not set the corresponding
$_GET[] element, which you can test with isset
  if (isset($_GET['fruit'])
    $fruit_choice=$_GET['fruit'];
  else
    $fruit_choice="Dont like fruit";

I /really/ should proof-read these posts before I hit send.
