Question

I’m trying to send post data between pages with Post. Not a form – like I may be passing validation error between pages or something (using it in several places).

The cURL is executing fine, but it’s just tacking on the new page at the bottom. How can I execute a cURL Post and load the following page?

So my goal is to send data between pages. I do not want to use GET or cookies as I do not want to rely on the user, and I’d prefer not to use $_SESSION as it is not so much directly about a session as sending private data between pages.

Thanks

$ch = curl_init($some_url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'myvar=something');
curl_exec($ch);
curl_close($ch);

I doubt the code has any relevance, as it’s about performing a task not code syntax (there may be one in this example but you’ll have to trust me it’s not the code that’s buggy as it’s retrieving fine).

You could separate your $_SESSION superglobal into arrays describing both the current user/session and any errors that your form has created. For instance,

$_SESSION = array(
  'user' => array(), // user data goes here
  'errors' => array() // validation data goes here
);

if (!$_POST['myvar'] == 'something') {
  $_SESSION['errors']['myvar'] = 'You must specify a value for <code>myvar</code>';
}

You would then be able to output errors on subsequent pages using a call something like this:

if (isset($_SESSION['errors'])) {
  foreach($_SESSION['errors'] as $error) {
    echo '<li>' . $error . '</li>';
  }
}
