I disagree. The form's action attribute is a URL, and a URL might
contain a query string. This is completely independent from the form
itself. In some cases there are reasons to use both, POST and GET.

No kidding? Hmmm - I do it that way often and it seems to work fine.

Well, here's what you wrote:

If the form's action attribute includes the parameter, the form's method
should be GET if you want to pass that. It would actually be more
correct to write the value to a hidden field instead of appending the
parameter to the form's action uri, then it wouldn't matter which method
was used:

<form action=" http://www.example.com/details_process.php"
method="whatever">
<input type="hidden" name="ref" value="<?php echo $_GET['ref'];?>

Not in the context of my reply, though. Based on the original post (which
is not completely clear), the form page LOADS with the $_GET, so I assumed
that a variable was being passed to it, which was then relayed to the
processing page. I didn't think of the alternate interpretation that you
mention.

Just in case someone were to read this message out of context, it might
be more correct to say that $_GET['ref'] contains the value "whatever"
and that the code $ref=$_GET['ref'] copies that into the $ref variable.

It might also be worth noting that the form's method must be "get", not
"post" for this to all work correctly.

Gary

That's just a way of passing a variable to a page. Let's assume that the
form page is loaded using a URL like this -

http://www.example.com/yourformpage.php?ref=whatever

When the form page loads, it parses the ref variable from the link, so now
$ref has the value "whatever".

The form's action would create a URL like this -

http://www.example.com/details_process.php?ref=whatever

so that when the form is processed by details_process.php, that process page
can act according to the value of the $ref variable, carried through from
the page calling the form, to the form, then to the page processing the
form.
