I have an online gateway which requires an HTML form to be submitted with hidden fields. I need to do this via a PHP script without any HTML forms (I have the data for the hidden fields in a DB)

To do this sending data via GET:

header('Location: http://www.provider.com/process.jsp?id=12345&name=John');

And to do this sending data via POST?

You can't do this using PHP.

As others have said, you could use cURL - but then the PHP code becomes the client rather than the browser.

If you must use POST, then the only way to do it would be to generate the populated form using PHP and use the window.onload hook to call javascript to submit the form.

Use curl for this. Google for "curl php post" and you'll find this: http://www.askapache.com/htaccess/sending-post-form-data-with-php-curl.html.

Note that you could also use an array for the CURLOPT_POSTFIELDS option. From php.net docs:

The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. This can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data.

here is the workaround sample.

function redirect_post($url, array $data)
{
    ?>
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <script type="text/javascript">
            function closethisasap() {
                document.forms["redirectpost"].submit();
            }
        </script>
    </head>
    <body onload="closethisasap();">
    <form name="redirectpost" method="post" action="<? echo $url; ?>">
        <?php
        if ( !is_null($data) ) {
            foreach ($data as $k => $v) {
                echo '<input type="hidden" name="' . $k . '" value="' . $v . '"> ';
            }
        }
        ?>
    </form>
    </body>
    </html>
    <?php
    exit;
}

It would involve the cURL PHP extension.

$ch = curl_init('http://www.provider.com/process.jsp');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "id=12345&name=John");
curl_setopt($ch, CURLOPT_RETURNTRANSFER , 1);  // RETURN THE CONTENTS OF THE CALL
$resp = curl_exec($ch);

You have to open a socket to the site with fsockopen and simulate a HTTP-Post-Request. Google will show you many snippets how to simulate the request.
