Browser response after form POST

Anon

Dear all

I am using the function below to pass variables between scripts using the post method.

From what i can see, it seems to pass the information to the server but doesn't accept any response. How can I use the post method and take the browser to the target page?

PS I have to use the post method because I am validating text variables which some proxy servers would truncate as url arguments.

Thanks

Marcus

function PostFormData($host, $path, $data) {
$fp = fsockopen($host,80);
fputs($fp, "POST $path HTTP/1.1\n");
fputs($fp, "Host: $host\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\n");
fputs($fp, "Content-length: ".strlen($data)."\n");
fputs($fp, "Connection: close\n\n");
fputs($fp, $data);
while(!feof($fp)) {
echo fgets($fp,128)."<br>";
}
fclose($fp);
}

I'm not that experienced, but why not simply use the "echo()" function? It will write it all to the browser?

Anon

The problem is the echo function only sends a response from the current script.

What I need to do is send data from one script to another and get the target script to become the current script which will output to the browser - ie exactly the same effect you get if a user presses a submit button.

Seeing

  echo fgets($fp,128)."<br>";

makes me think that the data you're sending probably isn't form-urlencoded at all. Anything you send back with the POST must be of the form:

var1=value1&var2=value2...

and it must be urlencoded so that spaces, slashes, etc are rendered as html hex sequences rather than literally.

I am using the loop...

while (list($key, $val) = each($HTTP_POST_VARS)) {
	$url_args .= "&$key=".urlencode(stripcslashes($val));
}

...(and then replacing the first & with a ?) to build the string containing the form data. This is then passed to the post function with...

PostFormData("host","path",$url_args);

I am confident this much is correct. What i am less confident of is the use of 'fgets', which reads directly from the file rather than accepting a response from a normal http request.

I would be very interested to see a working script that anyone has used to emulate a submit button and then continue browsing.

I used JS for emulation a submit button (my designer doesn't like the default form buttons :-)) But i don't think that is what you look for... sorry

Perhaps
fputs("Connection: close\n\n");
should go after
fputs($fp, $data);
?
