More purge orders (7 posts)

    Hello,

    I added purges for the following pages to your plugin ::

    posts
    purge archives (http://domain/YYYY,http://domain/YYYY/MM)
    purge categories

    plus I added support for a plugin called WordPress-Recent-Comments and another one called ajax-calendar.

    I will send another version soon that purges all the blog when comment is added and plugin recent comments is activated (I know that this widget should be done with esi or ajax, but as this is not standard, your plugin should add support for that)

    Here is the modified wp-varnish.php :

    <?php

    Nice work, any chance you can add support for purging when a new theme is applied? Thanks!

    Hi,
    sorry for the delay, back from hollidays, first of all I inform you that I am going to implement all the purge command that are compulsory for a multi site WordPress install. I will keep you updated on this forum.
    For your specific request, here is the modification to make to wp-varnish .php

    // When posts or pages are deleted
        add_action('deleted_post', array(&$this, 'WPVarnishPurgePost'), 99);

    Here is a modified version with new purges cases :

    - theme is switched
    - current theme options are changed
    - widgets are added or removed
    - widgets options are changed

    By the end of the week following cases will be added :
    - support for NextGen Gallery
    - support for media in general (images...)

    Any suggestion ?

    Hi again,

    well I decided to do things the right way, I forked this project on github, here is the url of the fork :

    https://github.com/ojdupuis/wp-varnish/

    I created a branch called More_purge_orders with the hope that the changes will be pushed back to the wp-varnish project.

    so we will have a nice change log, commit comments and so on.

    Olivier
