Hello !

I want to simulate a html form submit using php. How can i do that ?

I tried curl or fsocketopen but it return the result to my php page instead of redirecting to the POST destination url.

For example my form in html would be :

<form action="http://domain/destination.php">

In php i would like something like that :

phpfunctionSubmit($myPostVars, 'http://domain/destination.php');

This command would submit $myPostVars array and redirect to http://domain/destination.php.

Hi Martin,

maybe nonsense, but would @readfile('http://the-url’) (of course with encripted GET arguments instead of POST) be a work-around?

Thanx but i am stuck with POST.

This topic concern my eZSips (and new eZOgone) payment extension.

I am trying to get rid of the useless payment page which is only asking the payment type.

I want to put this choice on the basket, then the module would auto submit the correct values.

Cool idea as to get rid of the intermediate page!

What about then looking into how gateway selection works, find out where it is called (eZPaymentGatewayType ? ), and modify the calling code there in the first place instead of doing a hack with curl?

Unfortunately I'm pretty busy in another type of development (prices from matrix instead of product class) and can't spend much time in investigating further.

You've got to do something like this:

 $query="Login=".$username."&Password=".$password."&LoginButton=Log+in&RedirectURI=";
        $fp = fsockopen($site, $socket, $errno, $errstr, strlen($site));
        if (!$fp) exit();
        fputs($fp, "POST /".$adminsite."/user/login HTTP/1.1\r\n");
        fputs($fp, "Host: ".$site.":".$socket."\r\n");
        fputs($fp, "User-Agent: $user_agent\r\n");
        fputs($fp, "Referer: http://".$site.":".$socket."/".$adminsite."\r\n");
        fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
        fputs($fp, "Content-length: " . strlen($query) . "\r\n\r\n");
        fputs($fp, $query."\r\n");
        //fputs($fp, "Keep-Alive: 300\r\n");
        //fputs($fp, "Connection: keep-alive\r\n");

        fputs($fp, "Connection: close\r\n\r\n");
        fclose($fp);

Lukasz i tried your function but its not doing what i want :

eZHTTPTool::sendHTTPRequest($uri,$port,$post);

This function is posting the data (well i guess) but i am not redirected to my $uri address like a simple html form submit would.

Well at least i don't see any change in my address bar, i am still on the php page where the function is. Am i technically on the remote site ?

Is that possible with this function ?

Hi Martin,

maybe you could do a redirect after posting.

From the API:

static eZHTTPTool::redirect  ( $path,
		$parameters = array(),
		$status = false	 
	)

Hello Felix,

I am still stuck on this thing...which seems simple at the start... :\

What i try to do :

$url = 'https://secure.ogone.com/ncol/test/orderstandard.asp';
$port = 80;
$post = array('myvar' => 'test');

eZHTTPTool::sendHTTPRequest($uri,$port,$post,'momo', true);

But if i do a redirect after that then data won't be posted ?

I need to redirect to $url as if i use a simple html form with :

<form action="{$url}" method="POST"> 

At the end i could use a javascript "onLoad=submit()" but its not a clean way as my template would be loaded from extension's php code.

sorry my ignorance... where I can find the API for the function:

static eZHTTPTool::redirect ( $path, 
                $parameters = array(), 
                $status = false  
        )       

thanks a lot :)

After some research on this specific topic it is not possible to POST variables on a different domain with redirection using PHP (cross-domain post redirection).

Due to browser security policy this redirection (using header 307) would open a warning window on most browser.

For those interested this is the header to redirect :

header("Location: URL", TRUE, 307);

At the end if you are stuck with the POST method, as in most payment gateway, you can only use en dirty javascript function that would auto-submit the form :(

not with header 307 indeed:

> http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html
> If the 307 status code is received in response to a request other than GET or HEAD,
> the user agent MUST NOT automatically redirect the request unless it can be
> confirmed by the user

I think you want a 303 :

> This method exists primarily to allow the output of a POST-activated script to redirect
> the user agent to a selected resource.

But a 'normal' header 302 should work fine as well ?

Honestly, I don't think it's very pretty though. You are trying to have php receive a post request, perform another request in itself, and then *simulate* the response of that request to the client. Is there really no way you can force the original client to make the request that php now would make internally ?

Hello,

Thanx for your response but i am still stucked on this function.

I manage to do all kinds of post with php (cURL, fsocket, header()...etc) but none of them can actually redirect while posting.

I am just trying to POST variables to another domain with redirection (like an html form with action="otherdomain/page" would do.

Practically what would be the php command ?

Thanx in advance.
