Template Tags
=============

We provide a few template tags to make it easier to render
captcha challenges as well as manually render your own challenge.


**get_sitekey()**

    Returns the site key for the currently active provider.

**get_challenge_class()**

    Returns the css class name for the currently active provider.

    This is used to automatically bind challenges to HTML elements.

**get_callback_name()**

    Return the Javascript callback function name for the currently
    active provider.

**render_challenge(challenge_type="visible", text="submit", js_callback=[RECAPTCHA_JS_CALLBACK|HCAPTCHA_JS_CALLBACK], theme="light", size="normal")**

    Renders the challenge as follows:

    - Visible challenges (example, Checkbox) as renders as divs.
    - Invisible challenges are rendered as buttons.

    The ``text`` arguments specifies the text to use for buttons.

    Invisible challenges need a Javascript callback function. By default, this is set to either
    ``RECAPTCHA_JS_CALLBACK`` or ``HCAPTCHA_JS_CALLBACK``. The default callback provided will submit the form.

    You can override the kind of HTML generated by creating a template
    called ``challenge.html`` in the ``allcaptcha`` directory inside your
    global templates directory.
