    It's a little too bad there's no way to avoid a warning when the variable we're fetching is not set ...

        using 3.7.4 and getting an error as well. even testing for the existence fo a get/post var throws an error:
        {if ezhttp( 'myvar', 'get' ) } => returns false, but throws error
        the same with {if is_set( ezhttp( 'myvar', 'get' ) )}
        its a bug in my opinion..

    It would be nice if the ezhttp operator could return all vars in the array specified. ezhttp(GET) would return all $_GET vars for example.

    Your variable will be set to null if the requested http variable doesn't exist. If you take this into account in your template code, then you can just ignore the errors thrown.

      Solve the problem by a user defined template operator like (extension...autoloads)

      function getGETp()
      {
      if(isset($_GET["p"]))
      {
      return $_GET["p"];
      }

      return 0;
      }
