aFormToForm :: (Monad m, HandlerSite m ~ site) => AForm m a -> MForm m (FormResult a, [FieldView site] -> [FieldView site])

-- | Converts a form field into monadic form. This field requires a value

mreq :: (RenderMessage site FormMessage, HandlerSite m ~ site, MonadHandler m) => Field m a -> FieldSettings site -> Maybe a -> MForm m (FormResult a, FieldView site)

-- | Converts a form field into monadic form. This field is optional, i.e.
--   if filled in, it returns 'Just a', if left empty, it returns
--   <a>Nothing</a>. Arguments are the same as for <a>mreq</a> (apart from
--   type of default value).
mopt :: (site ~ HandlerSite m, MonadHandler m) => Field m a -> FieldSettings site -> Maybe (Maybe a) -> MForm m (FormResult (Maybe a), FieldView site)

-- | Applicative equivalent of <a>mreq</a>.
areq :: (RenderMessage site FormMessage, HandlerSite m ~ site, MonadHandler m) => Field m a -> FieldSettings site -> Maybe a -> AForm m a

-- | Applicative equivalent of <a>mopt</a>.
aopt :: MonadHandler m => Field m a -> FieldSettings (HandlerSite m) -> Maybe (Maybe a) -> AForm m (Maybe a)

-- | This function is used to both initially render a form and to later
--   extract results from it. Note that, due to CSRF protection and a few
--   other issues, forms submitted via GET and POST are slightly different.
--   As such, be sure to call the relevant function based on how the form
--   will be submitted, <i>not</i> the current request method.
--   
--   For example, a common case is displaying a form on a GET request and
--   having the form submit to a POST page. In such a case, both the GET
--   and POST handlers should use <a>runFormPost</a>.
runFormPost :: (RenderMessage (HandlerSite m) FormMessage, MonadResource m, MonadHandler m) => (Markup -> MForm m (FormResult a, xml)) -> m ((FormResult a, xml), Enctype)
runFormPostNoToken :: MonadHandler m => (Markup -> MForm m a) -> m (a, Enctype)
runFormGet :: MonadHandler m => (Markup -> MForm m a) -> m (a, Enctype)

-- | Similar to <a>runFormPost</a>, except it always ignores the currently
--   available environment. This is necessary in cases like a wizard UI,
--   where a single page will both receive and incoming form and produce a
--   new, blank form. For general usage, you can stick with
--   <tt>runFormPost</tt>.
generateFormPost :: (RenderMessage (HandlerSite m) FormMessage, MonadHandler m) => (Markup -> MForm m (FormResult a, xml)) -> m (xml, Enctype)

-- | Since 1.3.11
generateFormGet' :: (RenderMessage (HandlerSite m) FormMessage, MonadHandler m) => (Markup -> MForm m (FormResult a, xml)) -> m (xml, Enctype)

-- | <i>Deprecated: Will require RenderMessage in next version of Yesod</i>
generateFormGet :: MonadHandler m => (Markup -> MForm m a) -> m (a, Enctype)

-- | Creates a hidden field on the form that identifies it. This
--   identification is then used to distinguish between <i>missing</i> and
--   <i>wrong</i> form data when a single handler contains more than one
--   form.
--   
--   For instance, if you have the following code on your handler:
--   
--   <pre>
--   ((fooRes, fooWidget), fooEnctype) &lt;- runFormPost fooForm
--   ((barRes, barWidget), barEnctype) &lt;- runFormPost barForm
--   </pre>
--   
--   Then replace it with
--   
--   <pre>
--   ((fooRes, fooWidget), fooEnctype) &lt;- runFormPost $ identifyForm "foo" fooForm
--   ((barRes, barWidget), barEnctype) &lt;- runFormPost $ identifyForm "bar" barForm
--   </pre>
--   
--   Note that it's your responsibility to ensure that the identification
--   strings are unique (using the same one twice on a single handler will
--   not generate any errors). This allows you to create a variable number
--   of forms and still have them work even if their number or order change
--   between the HTML generation and the form submission.

type FormRender m a = AForm m a -> Markup -> MForm m (FormResult a, WidgetT (HandlerSite m) IO ())

-- | Render a form into a series of tr tags. Note that, in order to allow
--   you to add extra rows to the table, this function does <i>not</i> wrap
--   up the resulting HTML in a table tag; you must do that yourself.
renderTable :: Monad m => FormRender m a

-- | render a field inside a div
renderDivs :: Monad m => FormRender m a

-- | render a field inside a div, not displaying any label
renderDivsNoLabels :: Monad m => FormRender m a

-- | Deprecated synonym for <a>renderBootstrap2</a>.

-- | <i>Deprecated: Please use the Yesod.Form.Bootstrap3 module.</i>
renderBootstrap :: Monad m => FormRender m a

-- | Render a form using Bootstrap v2-friendly shamlet syntax. If you're

--   
--   Sample Hamlet:

customErrorMessage :: Monad m => SomeMessage (HandlerSite m) -> Field m a -> Field m a

fieldSettingsLabel :: RenderMessage site msg => msg -> FieldSettings site

-- | A helper function for creating custom fields.
--   
--   This is intended to help with the common case where a single input

--   
--   Since 1.1
parseHelper :: (Monad m, RenderMessage site FormMessage) => (Text -> Either FormMessage a) -> [Text] -> [FileInfo] -> m (Either (SomeMessage site) (Maybe a))

--   
--   Since 1.3.6
parseHelperGen :: (Monad m, RenderMessage site msg) => (Text -> Either msg a) -> [Text] -> [FileInfo] -> m (Either (SomeMessage site) (Maybe a))

-- | Since a <a>Field</a> cannot be a <a>Functor</a>, it is not obvious how
--   to "reuse" a Field on a <tt>newtype</tt> or otherwise equivalent type.
--   This function allows you to convert a <tt>Field m a</tt> to a
--   <tt>Field m b</tt> assuming you provide a bidireccional convertion
--   among the two, through the first two functions.
--   
--   A simple example:
--   
--   <pre>
--   import Data.Monoid
--   sumField :: (Functor m, Monad m, RenderMessage (HandlerSite m) FormMessage) =&gt; Field m (Sum Int)
--   sumField = convertField Sum getSum intField
--   </pre>
--   
--   Another example, not using a newtype, but instead creating a Lazy Text
--   field:
--   
--   <pre>
--   import qualified Data.Text.Lazy as TL
--   TextField :: (Functor m, Monad m, RenderMessage (HandlerSite m) FormMessage) =&gt; Field m TL.Text
--   lazyTextField = convertField TL.fromStrict TL.toStrict textField

timeFieldTypeText :: Monad m => RenderMessage (HandlerSite m) FormMessage => Field m TimeOfDay

-- | Creates a <tt>&lt;textarea&gt;</tt> tag whose input is sanitized to

htmlField :: Monad m => RenderMessage (HandlerSite m) FormMessage => Field m Html

-- | Creates an input with <tt>type="email"</tt>. Yesod will validate the

emailField :: Monad m => RenderMessage (HandlerSite m) FormMessage => Field m Text

-- | Creates an input with <tt>type="email"</tt> with the <a>multiple</a>

multiEmailField :: Monad m => RenderMessage (HandlerSite m) FormMessage => Field m [Text]

searchField :: Monad m => RenderMessage (HandlerSite m) FormMessage => AutoFocus -> Field m Text

--   
--   (When text is entered into a <tt>&lt;textarea&gt;</tt>, newline

newtype Textarea
Textarea :: Text -> Textarea
[unTextarea] :: Textarea -> Text

-- | Creates a group of radio buttons to answer the question given in the

--   False</tt>). Consider using the simpler <a>checkBoxField</a> if you
--   don't need to make this distinction.
--   
--   If this field is optional, the first radio button is labeled
--   "&lt;None&gt;", the second "Yes" and the third "No".
--   
--   If this field is required, the first radio button is labeled "Yes" and
--   the second "No".
--   
--   (Exact label titles will depend on localization).
boolField :: Monad m => RenderMessage (HandlerSite m) FormMessage => Field m Bool

-- | Creates an input with <tt>type="checkbox"</tt>. While the default

--   differentiate between an empty response (<tt>Nothing</tt>) and a no
--   response (<tt>Just False</tt>), this simpler checkbox field returns an
--   empty response as <tt>Just False</tt>.
--   
--   Note that this makes the field always optional.
