[pmwiki-devel] New adddeleteline2 redirect-args feature (not the same as previous email)

Mon Jan 1 01:22:38 CST 2007

Nils,

Along with the patch in the previous email, I have
gone one step further and added another small feature:
the ability to pass arguments to the page which
receives the redirect.  This probably seems a little
strange (that's why I didn't include it in the
previous email,) but it makes the previous patch even
more useful.  This patch can be used to redirect to a
'confirmation page' which can show you the details of
what you just pasted.  You can see an example of this
here:

http://www.theficks.name/test/adddeleteline/pmwiki.php?n=RedirectArgs.Form

But, what makes this particularly nice is the ability
to make a generic page that can follow any trail and
add any text to each page on the trail.  Both the
trail and the text can be selected by a form!  You can
see this demonstrated here:

http://www.theficks.name/test/adddeleteline/pmwiki.php?n=RedirectArgs.TrailForm

Again, the patch is inline.  This patch is to be
applied after the redirect patch from the previous
email.

Thanks,

-Martin

     New Features in this version:

!    This version adds a redirect feature which allows
a page to return to
!    the original form page immedeately after adding
text to a page.  To use
!    this feature, simply include a (potentially
hidden) parameter in your
!    form named: 'redirect_to' and set its value to
the page you want to
!    return to after adding text (probably
{$FullName}.)
!
!    After being redirected, the page variable
{$?redirect_from} will be set
!    to the page to which you have just added text to.
   */

     New Features in this version:

!    In addition to all the features of the redirect
patch, this
!    version adds support for redirect arguments. 
This is an array
!    of arguments, redirect_arg[], which will be added
to the query
!    string when redirecting after adding lines to a
page.  Simply
!    define these as parameters in your form somewhere
and they will
!    be available as page variables,
{$?redirect_arg[key]}, to
!    whatever page you define as the redirect page
with the
!    'redirect_to' parameter.
