index.php

The page for the main administration menu.

This page has a number of administration options, some of which are vestigial.  The options are as follows.

Of the above options, fixing directory permissions and updating blog data are largely unused.  Directory permissions are only relevant when switching file writing methods, and even then this option isn’t too useful.

Updating blog data applies mostly to a previous change in the storage format.  It is possible that this will be used again in the future, but there are no plans for it.

The upgrading to the current version, on the other hand, is more relevant.  It is used to create a new set of wrapper scripts in the standard setup.  “Wrappers scripts”, as used by LnBlog, are simply very small PHP scripts (usually less than five lines) that do nothing but use the PHP include() statement to execute another script.  The purpose of these scripts is to make all functions relevant to a blog accessible under the root blog URL, thus giving a clean URL structure to the entire blog.  Since new features requiring new pages are added from time to time, this upgrade function will probably be used once every few upgrades, depending on the changes between releases.

It is also important to note that the event system includes OnUpgrade and UpgradeComplete events for the Blog object.  These events are raised when this upgrade feature is run, so that plugins may perform any needed updates at that time.
