Text.Reform.Hamlet.String

This module provides functions creating Reform using Hamlet markup.

This module assumes that you wish for text based controls such as inputText and textarea to using String values. If you prefer Text see Text.Reform.Hamlet.Text.

Create an <input type="submit"> element

returns:

Just value

if this button was used to submit the form.

Nothing

if this button was not used to submit the form.

inputReset

=> String

value attribute. Used only to label the button.

-> Form m input error (HtmlUrl url) () ()

Create an <input type="reset"> element

This element does not add any data to the form data set.

inputHidden

Arguments

inputButton

Arguments

:: (Monad m, FormInput input, FormError error, ErrorInputType error ~ input)

=> String

value attribute. Used to label the button.

-> Form m input error (HtmlUrl url) () ()

=> [(a, lbl)]

(value, label)

-> (a -> Bool)

function which marks if a value should be checked (aka, selected) initially or not. Can match zero or more elements.

-> Form m input error (HtmlUrl url) () [a]

-> Form m input error (HtmlUrl url) () a

Create a group of <input type="radio"> elements

inputFile :: (Monad m, FormError error, FormInput input, ErrorInputType error ~ input) => Form m input error (HtmlUrl url) () (FileType input)

Create an <input type="file"> element

This control may succeed even if the user does not actually select a file to upload. In that case the uploaded name will likely be "" and the file contents will be empty as well.
