Unable to retrieve parameters from PUT method

[matthewgovaere]

Unable to retrieve parameters from the method 'PUT' using $request->params(). I'm assuming that the 'DELETE' method has the same issue.

Am I missing something? If not, I may be able to help add it in.

I have no problem sending data using PUT. Check the examples. Are you trying to retrive JSON data or form data?

@alexanis, I'm sending a curl request (with a PUT method) to a server running Klein. When I try to retrieve the parameters using $request->params(), they're not there. They are available if I use parse_str(file_get_contents('php://input'), $put_vars); instead though.

@matthewgovaere The parameters aren't automatically parsed from the request body using in Klein. $request->params() is a method to get the combination of parameters from multiple sources (including the GET and POST params).

Since request body's can have multiple formats/content-types (multipart/form-data, application/json, application/x-www-form-urlencoded, etc.) the Klein library doesn't try to parse the parameters for you based on the content-type. However, PHP will do this when using multipart/form-data (what goes in the $_POST var), so the library will use those parameters by default.

I may add parameter parsing by default, but since they can have a pretty opinionated parsing process I may make it optional or configurable somehow. Until then, you'll have to parse the parameters yourself.

I put this code (found via SO) in my base controller class.

public function http_put_data(\stdClass &$a_data) {
      $input = file_get_contents('php://input');
      preg_match('/boundary=(.*)$/', $_SERVER['CONTENT_TYPE'], $matches);
      if ($matches) {
          $boundary = $matches[1];
          $a_blocks = preg_split("/-+$boundary/", $input);
          array_pop($a_blocks);
      } else {
          parse_str($input, $a_blocks);
      }

      foreach ($a_blocks as $id => $block) {
        if (empty($block))
          continue;


        if (strpos($block, 'application/octet-stream') !== FALSE) {
          preg_match("/name=\"([^\"]*)\".*stream[\n|\r]+([^\n\r].*)?$/s", $block, $matches);
        }
        else {
          preg_match('/name=\"([^\"]*)\"[\n|\r]+([^\n\r].*)?\r$/s', $block, $matches);
        }
        if ($matches) {
            $a_data->{$matches[1]} = $matches[2];
        } else {
            $a_data->{$id} = $block;
        }
      }
    }

Then you access the data like so.

$put_data = (object)[];
$this->http_put_data($put_data);
echo $put_data->someVar;

EDIT: I had to make a change to handle empty $matches. I also made an $a_data object instead of array, as I like object syntax better for this to match Klein's style.

This probably doesn't handle every data type you can PUT. It works perfectly fine for form-data.
