    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..

      you can use in 3.9 (trunk) like:
      ezhttp_hasvariable( 'getVar','get' )
      or
      ezhttp( 'getVar','get','hasVariable' )

    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.

      You actually can get all the $_GET variables, or $_POST.

      {def $foobar=ezhttp()}

      This brings you all the http variables, be them get, post or session, in an array. You can check them out doing:

      {$foobar|attribute(show)}

  • ezhttp is not working if caching is turned on.

    i put
    {set-block scope=root variable=cache_ttl}0{/set-block}
    to all templates, because in other way ezhttp will return the same value...

  • or null

    Returns:
    Variable value or null

    test for non-existence using
    {if not(ezhttp('test'))}
    or
    {if ezhttp('test')|null()}
