Multiple forms per page
Hi,
I know it is not possible to have multiple forms on one page using
cforms. Is there some kind of workaround? I would like to put a
search-field on every page of a website. The website contains also a lot
of other cforms. So I would like to put a form with a searchfield (does
not need to be a cform) together with another form (this has to be a
cform) on one single page. Has anybody tried this before?
Thx
Werner

I'm not that well into CForms, but I don't think it will be a (large) problem to add a non-cform
form to every page and have it point to a totally different url than the cform... Might result in
dangling continuations, but these will time-out eventually.
Could also add it to the cform itself, but that might be awkward...

Thank you for your responses. I will use a simple form for the search
field. So there should be no problem.

I don't think this is a browser problem. Does your form template contain
the state widget?
<fi:state>
<ft:widget id="tab-state" />
</fi:state>
I don't know it the state-widget is really obligatory, but there is at
least a javascript error if it does not exist.

Re: Multiple forms per page
Posted by ia...@jpmchase.com.
Sounds like you're running into a variance between the IE and Firefox
object models. For best performance, I would recommend restricting your
javascript to the DOM standard.
You can find the object model for MSIE here:
http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/reference/dhtml_reference_entry.asp
You can find the object model for Firefox here:
http://developer.mozilla.org/en/docs/Gecko_DOM_Reference
You can find the JavaScript bindings for the DOM Level 2 Core can be found
here: http://www.w3.org/TR/DOM-Level-2-Core/ecma-script-binding.html
Assuming state is the id of the element and idx is text content to be set
for that element, the following should work (untested) for both MSIE and
Firefox:
var stateElem = document.getElementById(state);
var oldContent = stateElem.getFirstChild();
var newContent document.createText(idx);
stateElem.replaceChild(newContent, oldContent);

Yes, it's true. The tabs don't work when you have another form on the
page. This problem can be solved if you change the line in forms-lib.js:
document.forms[0][state].value = idx;
to
document.getElementById(state).value=idx;
Then there is another change in the xsl necessary, because the tab-state
widget is not generated with an id attribute (only with a name). In
forms-page-styling.xsl look for the line
<input type="hidden" name="{$state-widget}" value="{$active}"/>
and add the id attribute
<input type="hidden" name="{$state-widget}" id="{$state-widget}"
value="{$active}"/>
Then it works. I don't know it this is a hack or not.
As far as I have seen, this problem exists in 2.1.7 and 2.1.8 (without
Ajax)

If you use tabs presentation the js libraries use forms[0] in some
functions. If you have another form in the page the tabs don't work:
function forms_showTab(tabgroup, idx, length, state) {
// Change state value
if (state.length > 0) {
document.forms[0][state].value = idx;
}
I don't know if its used in any other place of the libraries.

There are some parts of the client-side JavaScript libraries that may
prevent the use of multiple CForms in a single page (this will have to
be fixed soon with Ajax apps where the concept of "page" becomes blurred).
But absolutely nothing prevents several other forms to exist on the
page. And your search field can very well post another URL.
The dangling continuations mentioned by Geert are not a problem, as they
will expire, just as they would if the user closed the browser window.
