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?
An old post but here is how I handled it. Using newms87's method:
if($action == "redemption")
{
if($redemptionId != "")
{
$results = json_decode($rewards->redeemPoints($redemptionId));
if($results->success == true)
{
$redirectLocation = $GLOBALS['BASE_URL'] . 'rewards.phtml?a=redemptionComplete';
// put results in session and redirect back to same page passing an action paraameter
$_SESSION['post_data'] = json_encode($results);
header("Location:" . $redirectLocation);
exit();
}
}
}
elseif($action == "redemptionComplete")
{
// if data is in session pull it and unset it.
if(isset($_SESSION['post_data']))
{
$results = json_decode($_SESSION['post_data']);
unset($_SESSION['post_data']);
}
// if you got here, you completed the redemption and reloaded the confirmation page. So redirect back to rewards.phtml page.
else
{
$redirectLocation = $GLOBALS['BASE_URL'] . 'rewards.phtml';
header("Location:" . $redirectLocation);
}
}
Your going to need CURL for that task I'm afraid. Nice easy way to do it here: http://davidwalsh.name/execute-http-post-php-curl
Hope that helps
Yes, you can do this in PHP e.g. in
Silex or Symfony3
using subrequest
$postParams = array(
'email' => $request->get('email'),
'agree_terms' => $request->get('agree_terms'),
);
$subRequest = Request::create('/register', 'POST', $postParams);
return $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);
A workaround wich works perfectly :
In the source page,, start opening a session and assign as many values as you might want. Then do the relocation with "header" :
<!DOCTYPE html>
<html>
<head>
<?php
session_start();
$_SESSION['val1'] = val1;
...
$_SESSION['valn'] = valn;
header('Location: http//Page-to-redirect-to');
?>
</head>
</html>
And then, in the targe page :
<!DOCTYPE html>
<?php
session_start();
?>
<html>
...
<body>
<?php
if (isset($_SESSION['val1']) && ... && isset($_SESSION['valn'])) {
YOUR CODE HERE based on $_SESSION['val1']...$_SESSION['valn'] values
}
?>
</body>
</html>
No need of Javascript nor JQuery.. Good luck !
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);
Another solution if you would like to avoid a curl call and have the browser redirect like normal and mimic a POST call:
save the post and do a temporary redirect:
function post_redirect($url) {
$_SESSION['post_data'] = $_POST;
header('Location: ' . $url);
}
Then always check for the session variable post_data:
if (isset($_SESSION['post_data'])) {
$_POST = $_SESSION['post_data'];
$_SERVER['REQUEST_METHOD'] = 'POST';
unset($_SESSION['post_data']);
}
There will be some missing components such as the apache_request_headers() will not show a POST Content header, etc..
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.
Alternatively, setting a session variable before the redirect and test it in the destination url, can solve this problem for me.
A better and neater solution would be to use $_SESSION:
Using the session:
$_SESSION['POST'] = $_POST;
and for the redirect header request use:
header('Location: http://www.provider.com/process.jsp?id=12345&name=John', true, 307;)
307 is the http_response_code you can use for the redirection request with submitted POST values.
Use curl for this. Google for "curl php post" and you'll find this: http://www.askapache.com/htaccess/sending-post-form-data-with-php-curl.html.
Note that you could also use an array for the CURLOPT_POSTFIELDS option. From php.net docs:
The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. This can either be passed as a urlencoded string like 'para1=val1¶2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data.
here is the workaround sample.
function redirect_post($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="' . $v . '"> ';
}
}
?>
</form>
</body>
</html>
<?php
exit;
}
I used the following code to capture POST data that was submitted from form.php and then concatenate it onto a URL to send it BACK to the form for validation corrections. Works like a charm, and in effect converts POST data into GET data.
foreach($_POST as $key => $value) {
$urlArray[] = $key."=".$value;
}
$urlString = implode("&", $urlArray);
echo "Please <a href='form.php?".$urlString."'>go back</a>";
/**
* Redirect with POST data.
*
* @param string $url URL.
* @param array $post_data POST data. Example: array('foo' => 'var', 'id' => 123)
* @param array $headers Optional. Extra headers to send.
*/
public function redirect_post($url, array $data, array $headers = null) {
$params = array(
'http' => array(
'method' => 'POST',
'content' => http_build_query($data)
)
);
if (!is_null($headers)) {
$params['http']['header'] = '';
foreach ($headers as $k => $v) {
$params['http']['header'] .= "$k: $v\n";
}
}
$ctx = stream_context_create($params);
$fp = @fopen($url, 'rb', false, $ctx);
if ($fp) {
echo @stream_get_contents($fp);
die();
} else {
// Error
throw new Exception("Error loading '$url', $php_errormsg");
}
}
