page_open(array("feature" => "classname"))
This function is to be called with an array of page
features/classname pairs. Valid features are:
sess : This page makes use of session variables.
auth : This page uses session authentication. If you
specify the auth feature, you MUST specify
the sess feature, also.
perm : This page is protected by permissions and only
accessible to authenticated users with matching rights.
If you specify the perm feature, you MUST specify
the auth and sess features, also.
user : This page makes use of user variables. If you specify
the user feature, you MUST specify the auth and
sess features, also.
Each feature specifies the name of the class that implements that feature,
for example
page_open(array("sess" => "Shop_Session"));The function creates an instance of Shop_Session as
$sess and initializes it. It also checks feature
dependencies. Note that you are expected to provide an
implementation of the class Shop_Session. This is
usually done in local.inc and usually you do so by
extending the provided Session class.
Examples on how to do this is given in the documentation later
when the classes are introduced.
At the end of your page (after all results have been calculated)
you have to call page_close(). This will save all
page state, session and user variables into database. Changes to
session or user variables after page_close() has
been called are not recorded. It is recommended that you call
page_close() only once on your page.
