I'm really struggling to understand how to use these formlets, so
please bear with me here :-)
I've been playing with the continue blog application, and instead of
input fields consisting of just a single row when you're adding a new
post, I'd like to have a TEXTAREA field instead for the post body.
I've got the following formlets,
(define make-post-formlet
(formlet
(#%#
(div ((class "make-post-title"))
"Title:" ,{input-string . => . title})
(div ((class "make-post-body"))
"Post:" ,{(textarea-input) . => . post})
(input ((type "submit"))))
(list title post)))
(define display-post-confirm
(match-lambda
[(list title post)
`(html
(head (title "Post confirm page"))
(body
"Post title: " ,title
"Post contents:" ,post))]))
Notice in make-post-formlet, I'm using the predefined textarea-input
formlet. A lot of the other formlets have optional attributes you can
set specifying various features of that particular HTML entity, but I
don't understand how to specify the row and column size for the
textarea-input formlet.
Any help on how to do this, or whether I should be considering a
different approach would be much appreciated.
Thanks,
Horace.
