Form: GET works but POST doesnt!?

[CRON]

Hi all:
I'm a little confused here: When I submit this form with GET it works
like a dream. But when I use POST, the recieving script just doens't
recieve the vars. Why would this be?

the form:
<form action="0scripts/invite.php" method="POST" enctype="text/plain"
onSubmit="compileEmails()">
<textarea name="notes" cols="65" rows="5"
id="notes"></textarea>
<p>Your invitation will be sent to the following email
addresses:
<input name="loopcount" type="hidden" value="<? echo
$loopcount;?>">
<br>
<textarea name="emaillist" cols="81" rows="5"
id="emaillist" style="background:#FFFFFF; border-color:#FFFFFF;
color:#999999; font-weight:normal; font-size:7pt;"></textarea></p>
<p align="right" class="backLightGrey">
<input type="submit" name="Submit" value="Send Invites"
</p>
</form>


Thanks a lot
Ciarán

Does the script that is targeted (0scripts/invite.php) support the
POST method?

To expand on what Chris says, GET variables are in the _GET array
whereas POST variables are in the _POST array. If you want to get them
from either array try something like :

function GetFormValue ($key, $default = '')
{
if (array_key_exists ($key, $_POST))
return $_POST [$key];
if (array_key_exists ($key, $_GET))
return $_GET [$key];
return $default;
}

}

Or: extract($_POST);
But isn't that a safety risc? I prefer $var=$_POST['var'];

Only two enctypes must be supported: application/x-www-form-urlencoded
and multipart/form-data. The behaviour when the enctype is text/plain,
or any other content-type, is unspecified.

The $_REQUEST-Array contains both, the POST and the GET variables. I'm
not surte what happens if the same variable is send by post and by get
but I would guess that the POST-value overrides the other.

This does only make $_POST variables available but not the GET ones. You
have to add extract($_GET);.

It is. It has the same effect which was corrected by adding the
possibility to switch register_globals off: every variable which is
posted is set, no matter if the author of the script want it to be set
by the user or not. In some cases one can override the values of
variables in the script by simply posting variables with the same name
which is a security problem.

I prefer $var=$_POST['var'];

The better poosibility. Only the variable you want to be set by post (or
get) are set, all the other post (or get) variables are ignored.

Well does this answer it?

GET VAR
Array
(
[parameter] => ValueByGet
)

POST VAR
Array
(
[parameter] => ValueByPost
)

Also not what happens when you access via the $_REQUEST array...

$_GET VAR
Array
(
[parameter] => ValueByGet
)

$_POST VAR
Array
(
[parameter] => ValueByPost
)

$_REQUEST VAR
Array
(
[parameter] => ValueByPost

This is just what I've said: If a variable is posted twice the
POST-value overrides the GET one. So where is the problem?

If the 'parameter' is sent via POST and included via URL simulating a
GET (how I did the test) that values discrete within respective $_POST
and $_GET arrays but in $_REQUEST the POST will trump the GET. That was
all I was illustrating.
