Collecting form variables and passing them along. . .

[JohnnyBlaze]

hello all, I'm trying to do something very simple, hopefully someone can help me out :

I need to create a basic form which collects user input and POSTs it to a specified URL, but with additional fields that are tacked on after the input is submitted.

So for example, my ultimate goal is to collect some info via the form, add a few more fields to it(by sending the input fields to another scritpt, we'll call it scripta.php) and have all that combined data post to yet ANOTHER sript, we'll call that http://www.mydomain.com/formpost.php

My problem is that I'm not sure how to take the form input and send it to "scripta.php" which adds the extra fields that I need.

From there all the fields would be submitted as one form to http://wwww.mydomain.com/formpost.cgi. I guess I'm having trouble having the "scripta.php" autmatically submit the info to http://www.mydomain.com/formpost.php

Maybe I can illustrate to make it clearer :

My basic form collecting the initial info :

<form action=http://www.mydomain.com/scripta.php method=POST>

<INPUT type="radio" name="sex" value="Male"> Male<BR>
<INPUT type="radio" name="sex" value="Female"> Female<BR>
<INPUT type="radio" name="Over 18" value="Yes"> Yes<BR>
<INPUT type="radio" name="Over 18" value="No"> No<BR>
<INPUT type="text" id="Firstname"><BR>
<INPUT type="text" id="lastname"><BR>
<INPUT type="submit" value="Send"> <INPUT type="reset">
</FORM>

Once this is submitted to "scripta.php", I would like it to add a few more predefined fields to the ones submitted, and POST all of them to http://www.mydomain.com/formpost.php

I know I'm making this sound more complicated than it is, but I'm still kinda new to this. . .

Hi,
when you post this form, in the scripta.php file you receive $sex, $Firstname and $lastname var (some problem with "over 18" for the blank space... i think this is not allowed...)

If your globals are off you must access to var with $POST[] array:
$POST["Firstname"], $_POST["lastname"] etc...

Be care with upper/lowercase.

hi, thanks for the reply.

over 18 was just an example so that shouldn't be a problem. I understand that I can receive those variables using $_POST, but I can't figure out how to take those variables, add some more to them, and automatically pass them along to the final script.
So say I received $sex,$Firstname, etc. to scripta.php, I want it to add $customerID and $trackingnum(values would be predefined) and have ALL of those post to the final script, automatically.

I think you need jscript...

Just an example:

insform.php

 
<form action="sender.php" method=post>
<input name="inpt_1" value="">
<input name="inpt_2" value="">
<input type=submit>
</form>

sender.php

 
<? 
$inpt_1=$_POST["inpt_1"];
$inpt_2=$_POST["inpt_2"];

//.. do calc
$inpt_1=$inpt_1*0.2;
$inpt_2=$inpt_2*0.2;
?>
<form name="auto" action="show.php" method=post>
<input type=hidden name="calc_1" value="<?=$inpt_1?>">
<input type=hidden name="calc_2" value="<?=$inpt_2?>">
</form>
<script>document.auto.submit()</script>

show.php

 
<? 
echo $_POST["calc_1"];
echo $_POST["calc_2"];
?>

I had to do something similar to make a script that would send a message to my cell phone by POSTing variables to a web form on my cell phone providers site. I found a great HTTP_POST function, which I'll post below, along with the cell phone script as an example:

// http.inc by [email][e-mail][/email]
// [url]http://nf.wh3rd.net/[/url]

function http_post($server, $port, $url, $vars) {

// example:
//  http_post(
//	"www.fat.com",
//	80, 
//	"/weightloss.pl", 
//	array("name" => "obese bob", "age" => "20")
//	);

$user_agent = "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)";


$urlencoded = "";
while (list($key,$value) = each($vars))
	$urlencoded.= urlencode($key) . "=" . urlencode($value) . "&";
$urlencoded = substr($urlencoded,0,-1);	

$content_length = strlen($urlencoded);

$headers = "POST $url HTTP/1.1
Accept: */*
Accept-Language: en-au
Content-Type: application/x-www-form-urlencoded
User-Agent: $user_agent
Host: $server
Connection: Keep-Alive
Cache-Control: no-cache
Content-Length: $content_length

";

$fp = fsockopen($server, $port, $errno, $errstr);
if (!$fp) {
	return false;
}

fputs($fp, $headers);
fputs($fp, $urlencoded);

// I ([e-mail]) commented out these lines because they were causing the script to fail for my implementation, and weren't needed.
//$ret = "";
//while (!feof($fp))
//	$ret.= fgets($fp, 1024);

fclose($fp);

return true;

}

function SendTextMessage ($message) {
	$server = "mycricket.com";
	//$message = "This is a test message buddy!";
	$url = "/text/sendto_sms_system.asp?Step=2";
	$vars = array(
		"Cricket_Phone_Number" => "4026122567",
		"from" => "4022911630",
		"email_from" => "[e-mail]",
		"msg" => $message//,
		//"B1" => "Submit"
	);
	if (http_post($server, 80, $url, $vars)) {
		return true;
	} else {
		return false;
	}
}

if (SendTextMessage("Test message!!!")) {
	echo("Successfully sent text message!");
}  else {
	echo("FAILED sending text message.");
}

so thats basically how you do it... take the vars submitted by the user and put them into an array... were you can rename them if need be and add on any variables you want.. then send them through the script and all should be well.
