Question

I have a sample Restler class:

   class Author {
      ....

      function post($request_data=NULL) {
         var_dump($request_data);
         var_dump($_FILES);
         var_dump($_REQUEST);

         return $this->dp->insert($this->_validate($request_data));
       }

      ....
  }

I’m trying to POST file and some data to Restler service by simple HTML form:

  <FORM action="http://host/index.php/author" enctype="application/x-www-form-urlencoded" method="post">
      Name:  <INPUT type="text" name="name" value="dima"><BR>
      Email: <INPUT type="text" name="email" value="[e-mail]"><BR>
      File:  <INPUT type="file" name="files"><BR> 
      <INPUT type="submit" value="Send"> <INPUT type="reset">
  </FORM>

It is clear, that the $_FILES array will be empty, but $_REQUEST and $request_data will have three variables:
name = "dima", email = "[e-mail]" and file = "selected file name".

In the next test, I changed the form enctype value to multipart/form-data.

  <FORM action="http://host/index.php/author" enctype="multipart/form-data" method="post">
      Name:  <INPUT type="text" name="name" value="dima"><BR>
      Email: <INPUT type="text" name="email" value="[e-mail]"><BR>
      File:  <INPUT type="file" name="files"><BR> 
      <INPUT type="submit" value="Send"> <INPUT type="reset">
  </FORM>

When I press submit form, in the $_REQUEST array, I will see the same three variables, the $_FILES array will be filled with uploaded file information, BUT the $request_data array will be empty!!

Can anybody help in this situation? Where have I made a mistake?

I have solved this issue, by writing Restler plugin, may be other will have the same problem:

    const RESPONCE_MIME     = 'application/json';
    const EXTENSION         = 'post';

    public function getMIMEMap() {
        return array(self::EXTENSION=>self::REQUEST_MIME);
    }

    public function getMIME(){
        return self::RESPONCE_MIME;
    }

    public function getExtension(){
        return self::EXTENSION;
    }

    public function setMIME($mime){
        //do nothing
    }

    public function setExtension($extension){

    }

    public function encode($data, $human_readable=FALSE){
        return $human_readable ? 
        $this->json_format(json_encode(object_to_array($data))) : 
        json_encode(object_to_array($data));
    }

    public function decode($data){
        return $_REQUEST;
    }

    public function __toString(){
        return $this->getExtension();
