Forms

[shapper]

Hello,

Can I have two forms in a page?

And can I have one form inside another form?

Thanks,
Miguel

Can I have two forms in a page?

Yes. Why not? Apart from common sense, which says that it's not usually a
good idea.

And can I have one form inside another form?

No. Even the HTML syntax forbids it.

Now, what is your _real_ problem? What did you plan to achieve by having
nested forms?

On a system to manage users, some users are professors.
So I have a form to edit the CV of the professor but also a form to
Add and Remove Themes that the professor lectures.

I would like to have both forms on the same page ... in this case it
makes sense
So on form one I would have:
- input CV
- input Notes
- input Save button

And on second form I would have:
- select Themes
- checkboxes Levels
- input Notes
- input Add button
And a list after it with the subscribed themes

I think it makes sense to have this on the same page.

The nested form was just curiosity ...

That page does not state if one can have more than one form on a page.

More importantly neither does it say that a form may not be nested within
another form. The specifications are much more concise:

Clearly a form can not contain another form, as per the -(FORM) bit at the
top of the DTD extract.

If you quote signatures on regular basis, you might end up with getting
ignored on a regular basis.

On a system to manage users, some users are professors.
So I have a form to edit the CV of the professor but also a form to
Add and Remove Themes that the professor lectures.

These are both operations on data about an individual, so it might make
sense to have both kinds of operations on the same page. But why not in the
same form?

Quite possibly, but the normal way of doing such things is a single form,
with an action like "Update", which updates whatever information has been
entered. If you use two forms, then there is no reliable way of making them
share some input fields.

Using a single form implies that the server-side form data handler must be
capable of dealing with any data (as it should anyway) and specifically
process different fields, performing several updates in one transaction.

The nested form was just curiosity ...

I see.
