You can pass parameters in the URL for a POSTed form:

## page2
<form method="post" action="page3.p hp?data=$urlenc oded_data">
<input type="text" name="address">
<input type="submit">
</form>

## page3
mail('your_addr ess@example.com ', 'form data with contact details',
"Someone entered this data:\n\n" .
"{$_GET['data']}\n\n" .
"The user details are:\n" .
" address: {$_POST['address']}");

You can use <input type="hidden" value="your_val ue_from_previou s_form"> in
your mini form on page2. Thus, you can POST results from form on page1 to
page3 via form on page2.

Method is POST. Are you sure that he can obtain GET data in this case?

Yes.

<form method="post" action="test.ph p?id=one">
<input type="text" name="id" value="two">
<input type="submit">
</form>

and on test.php you can do:

<?php
echo $_GET['id']; // one
echo $_POST['id']; // two, if it hasn't been changed
?>

If you use $_REQUEST['id'] it will get "one" or "two" depending on your
configuration.

Thanks - I'm halfway there, I think. I'm getting my POST data through to the
next page, but I'm not sure how or if I can use the URLENCODE command within
the form? Whereas I used to have the data passed on like so:

echo '<a href="mail.php? radiochoice=', urlencode($radi obutton),
'&radiomoderntr ad=', urlencode($radi omoderntrad),
'&radiocoord= ', urlencode($radi ocoord),
'&radiopacking= ', urlencode($radi opacking),
'&i1=', urlencode($item 1),
'&i2=', urlencode($item 2),
'&i3=', urlencode($item 3),
'&i4=', urlencode($item 4),
'&i5=', urlencode($item 5),
'&i6=', urlencode($item 6), ETC.

when I try to do a (obviously botched?!) cut and paste job to get the
following:

<form name="form1" method="post" action="finalte st.php?stevetes t=",
urlencode($item 1),' stevetest2=', urlencode($item 2),'">
<p>

<input type="text" name="textfield ">
</p>
<p>
<input type="submit" name="submit" value="Submit">
</p>
</form>?>

I get a 'Parse error: parse error, unexpected '<'' - yes, my grasp is syntax
is pretty crappy, but I'm no programmer - just a GFX guy trying to learn!
Anyone able to help me mastering this last piece of my jigsaw?

THANKS!

Steve
