The StaticPages plugin allows you to put some .html or .php files
|
||
|
|
into dedicated directories, which then will get available with their
|
||
|
|
basename as ewiki pages. The files can be in wiki format (.txt or no
|
||
|
|
extension), they can also be in .html format and they may even contain
|
||
|
|
php code (.php).
|
||
|
|
|
||
|
|
Of course it is not possible to provide anything else, than viewing
|
||
|
|
those pages (editing is not possible), but it is of course up to you
|
||
|
|
to add php code to achieve some interactivity.
|
||
|
|
The idea for this plugin was 'borought' from http://geeklog.org/.
|
||
|
|
|
||
|
|
In your static page .php files you cannot do everything you could
|
||
|
|
normally do, there are some restrictions because of the way these static
|
||
|
|
pages are processed. You need to use $GLOBALS to access variables other
|
||
|
|
than the $ewiki_ ones. To return headers() you must append them to the
|
||
|
|
$headers[] or $ewiki_headers[] array.
|
||
|
|
|
||
|
|
If you define("EWIKI_SPAGES_DIR") then this directory will be read
|
||
|
|
initially, but you could also just edit the following list/array of
|
||
|
|
directories, or call ewiki_init_spages() yourself.
