A simple class providing a cute adapter for get/post requests.

Usage



$r = &new Request(POST_METHOD | GET_METHOD);

#$r = &new Request(POST_METHOD); //just post

#$r = &new Request(GET_METHOD); //just get =b



if($r->has('name'))

  echo $r->get('name'), $r->name;



echo $r->get('year', '2006');



if($r->isPosted())

  echo 'This was a post =b';





if($r->isFile('file'))

  if($r->file->isUploaded()){

    echo 'The file was uploaded';

    if($r->file->hasError())

      echo 'And there was an error when uploading';

    else{

      echo 'Moving ' . $r->file->path;

      $r->file->save('uploads/' . $r->file->name)

    }

  }
