[hunchentoot-devel] How do I read the submit button value?

Matt,
I'm trying to guess what you are doing.

Hans has show you the functions you have to use and told you why you
didn't get any value for the submit button, because you forgot the
name attribute inside the input of type 'submit'.

Having said that, I think, but maybe I'm wrong, that you are planning
to have two submit buttons inside your page and then decide which
action to call depending on the button the user hits.

If you are going to use <input type='submit' ... you will bind your
action choices on button labels, this because with input/submit the
value is also the label.

If, instead, you are going to use <button> tag you may use value as
submission parameter, but you can have the description you want for it
(you may consider to decorate button label as well).
Using button your action/parameter will not suffer of the i18n 'problem'.
You'll also gain more eye-candy because you'll be able to do something like

<button name="submit" type="submit" value="action1"><span
class="bold">Delete</span> all</button>

So input/submit and button/submit are only apparently identical.

Cheers,
kiuma
