processing 2 things in one form. is it possible?

[crescent_au@yahoo.com]

hi all,

i am creating a form that returns to itself like this:
<form name="form1" action="<?php echo $_REQUEST['PHP_SELF']; ?>"
method="post">

Upon clicking submit, I want the form to return to "itself" (does the
input fields validation). If the validation is false, the initial input
values are displayed on the fields. If the validation is correct, it
should go to an external file (on different server) and does the rest
of the processing such as sending mail or writing to a file, etc (could
be anything). There are basically 2 tasks here. Is this achievable in a
single form. I tried to include external file after validation but it
fails to call a function inside that file as the file resides on a
different server.

Can someone show me the right direction?

Thanks

if($_SERVER['REQUEST_METHOD '] == 'GET')
{
...show the form
}
elseif post
{
validate the post vars
if success
use the header() function to jump the external page
else
show the form again, you'll still have
the $_POST array hanging around to initialize
the form elements with, so the form looks
like it did just before the first submit
}

The only problem I see with that is that the OP probably wants to take data
along to the new script(on different server) and header won't do that by
itself afaik. You may need to use curl to repost your data to the other
server.

One solution is to use fsockopen to post the data to the other server.
Create a function which takes as input a URL to post to, and an array
of variables to be posted. This function could then connect the URL,
post the data, and return the response. Note that the response will
contain all data return from the server (including headers). Therefore,
the remote server's page should echo results in an easily parsable
form. I usually do something along the lines of:

<!-- OUTPUT STARTS HERE -->
<result>1</result>

This way you can easily cut off the headers, and look at the actual
result of the operation. Here is a code snippet of using fsockopen:

$request.="POST ".$URL_Info["path"]." HTTP/1.1\r\n";
$request.="Host : ".$URL_Info["host"]."\r\n";
$request.="Refe rer: $referrer\r\n";
$request.="Cont ent-type: application/x-www-form-urlencoded\r\n" ;
$request.="Cont ent-length: ".strlen($data_ string)."\r\n";
$request.="Conn ection: close\r\n";
$request.="\r\n ";
$request.=$data _string."\r\n";


$fp = fsockopen($URL_ Info["host"],$URL_Info["port"]);
fputs($fp, $request);
while(!feof($fp )) {
$result .= fgets($fp, 128);
}
fclose($fp);
