add more parameters into a form page

[shoa]

Hello

In the jsp page that display list of books, I have:

<td>
<form action="<c:url value="book.html"/>">
<input type="hidden" name="id" value="<c:out value="${book.bookId}"/>" /><input type="submit" name="edit" value="Edit" /></form>
</td>

When I click edit button for a book (with Id =1), I have this in URL:

http://localhost:8080/book/book.html?id=1&edit=Edit

This page will show the details of the book. As the book may have one or more comments and I need to update, delete any of these comments. To edit a comment with Id =2, I need to have one more parameter for it, example it is commentId = 2.

I tried:

<td>
<c:url var="editComment" value="book.html"> <!-- I need to display the edit comment in the same book detail page -->
<caram name="commentId" value="2"/>
</c:url>
<a href="<c:out value="${editComment}"/>">edit Comment</a>
</td>

My URL now is http://localhost:8080/book/book.html?commentId=2

But I NEED to have this in URL:

http://localhost:8080/book/book.html...it&commentId=2

Could you please tell me how to do this. I use a simpleFormController as all of actions happend on only one form.

Many thanks

Why not use a form with hidden fields? There is no reason the form cannot use a get instead of a post (action="get").

If you want to use c:url you can still do:

  <c:url var="editComment" value="book.html?commentId=2"/>

I think, although I don't use c:url very much.

I cannot use this as I will lost the book Id and edit parameter in (http://localhost:8080/book/book.html?id=1&edit=Edit)

In the jsp page, I have book details and some comments in a table( with people names and their comments). I need to update book details and update, add comments. So I cannot use forms for comments as I cannot use forms (for update or add more comments) inside a form (for update book details).

There is any better way to do this.
Thank you

I see.

Is there any reason you cannot have each section it's own form and submit to different controllers which all have the same successView?

i.e. Image a page which looks like:

     ---------------------------------------
    |   Book name: Expert Spring MVC         |
    |                    and Web Flow               |
    |                                                      |
    |            Delete  Edit Add Comment       |
    |                                                      |
    |                                                      |
    |   Comment 1: this is a really good book |
    |                               Delete  Edit       |
    |                                                      |
    |   Comment 2: it really is!                    |
    |                               Delete  Edit       |
     ---------------------------------------

(excuse the formatting horror )

you could have a form wrapping the book section, and then a form wrapping each comment section. The book form might submit to /books/edit.htm or /books/delete.htm etc.

Would that work for you?

Thanks Yatesco

At the moment I use ONLY one FormSimpleController for the edit book page. I use functions isFormChangeRequest and onFormChange to update comments. That is why I want to use <a href tag for update/add Comments AND I use "onSubmit" for update Book details (after update/add comment, user then update whole book.)
Do you have any idea about this. I will try your solution.

Well, I would question the benefit of that over the benefit of having seperate controllers.... whenever I see a class with "if this then" in lots of methods it seems to smell of one class coping with two instances; which is exactly what (I think) your single formController is doing

[shoa]

You are right, I have many if-then. it is not good

>you could have a form wrapping the book section, and then a form wrapping each comment section

However, using your method, I really donot know how many controllers (or what kind of controller) I should use as one book may have many comments
Thanks

[Colin Yates]

I would have one controller for managing the book and one controller for managing the comments....you certainly don't want one controller per comment if that is what you were implying
