def button_to(title, url='', **html_options):
    """Generate a form containing a sole button that submits to
    ``url``.

    Use this method instead of ``link_to`` for actions that do not have
    the safe HTTP GET semantics implied by using a hypertext link.

    The parameters are the same as for ``link_to``.  Any
    ``html_options`` that you pass will be applied to the inner
    ``input`` element. In particular, pass

        disabled = True/False

    as part of ``html_options`` to control whether the button is
    disabled.  The generated form element is given the class
    'button-to', to which you can attach CSS styles for display
    purposes.

    The submit button itself will be displayed as an image if you
    provide both ``type`` and ``src`` as followed:

         type='image', src='icon_delete.gif'

    The ``src`` path should be the exact URL desired.  A previous version of
    this helper added magical prefixes but this is no longer the case.

    Example 1::

        # inside of controller for "feeds"
        >> button_to("Edit", url(action='edit', id=3))
        <form method="POST" action="/feeds/edit/3" class="button-to">
        <div><input value="Edit" type="submit" /></div>
        </form>

    Example 2::

        >> button_to("Destroy", url(action='destroy', id=3),
        .. method='DELETE')
        <form method="POST" action="/feeds/destroy/3"
         class="button-to">
        <div>
            <input type="hidden" name="_method" value="DELETE" />
            <input value="Destroy" type="submit" />
        </div>
        </form>

    Example 3::

        # Button as an image.
        >> button_to("Edit", url(action='edit', id=3), type='image',
        .. src='icon_delete.gif')
        <form method="POST" action="/feeds/edit/3" class="button-to">
        <div><input alt="Edit" src="/images/icon_delete.gif"
         type="image" value="Edit" /></div>
        </form>

    .. note::
        This method generates HTML code that represents a form. Forms
        are "block" content, which means that you should not try to
        insert them into your HTML where only inline content is
        expected. For example, you can legally insert a form inside of
        a ``div`` or ``td`` element or in between ``p`` elements, but
        not in the middle of a run of text, nor can you place a form
        within another form.
        (Bottom line: Always validate your HTML before going public.)
