To include anchor in a URL, provide the id with the '#' key in the
URL. If your anchor ID is 'foo', you'd use something like:
'controller' = 'xxx', 'action' = 'yyy', '#' = 'foo'
... in the form action. You need to specify it there, and not in a
controller redirect, because the page is not reloaded when there are
validation errors. The form submits to the same URL, and, if there are
NO errors, the request is redirected. Otherwise, the view for that URL
is rendered as requested, only this time displaying validation
errors..
OT FYI: You can use any HTML element with id=foo; there's no need to
use an A tag (I believe that that use of A is deprecated in HTML5).

Hi,
I've successfully set up a contact form in cakePHP, and when
validation rules in my model don't pass, the form is reloaded with all
my validation errors displayed properly. That battle was won :)
Now for the tricky part.
Can anyone think of a way to not only have the form page reload with
error messages, but jump to an anchor link at the top of the form if
errors are present? I'm sure I could use javascript for this, but as
it stands I can't count on users having javascript enabled. Currently
when the form reloads with error messages in place, users have to
scroll down from the top of the page, and I see this as a slight
problem.
Obviously CakePHP is smart enough to redirect to an appropriate URL
when validation fails, all I need to do is add #myAnchor to the end of
that URL somehow. Any ideas?
I've thought of adding a line to my beforeFilter that says something
like
1. if we're visiting the form page
2. and if some error flag variable is set
3. catch the URL somehow
4. Add the anchor to the end
But I'm not sure on the specifics of how I'd go about this, and as
this filter would run before the any page in the controller runs, I
have concerns about efficiency. Any ideas?
Thanks in advance for your input.
