For help making this question more broadly applicable, visit the help center. Closed 12 years ago.

    What I want to do

    I want to upgrade Wordpress programmatically to a later version. That I want to do with PHP, lets say from /?upgrade_wp=true

    I already know how to get the URL of the latest version so I don't having any problem with checking for versions or finding the right URL.

    Answers I want

    • A link to a tutorial of how this is done.
    • A plugin that does this and not so much more.
    • A hint to the functions that I need to use.

    Answers I don't want

    • The way to do it with SVN or subversion.
    • Answers containing Wordpress MU.
    • How to manually doing this.
    • How to do this with other code than PHP.

    • 3 Why would you want to install a plugin that does something WP already does out of the box? – moraleida Commented Jun 10, 2012 at 19:43
    • 2 Absent some example of a non-niche use case, Close-voted as too localized. – Chip Bennett Commented Jun 10, 2012 at 19:49
    • 5 Answers I want/don't want = invitation for being sarcastic, but I'll refrain myself & instead some useful info: study how InfiniteWP does it... – brasofilo Commented Jun 10, 2012 at 22:55
    • @brasofilo Thanks! InfiniteWP was just what I was going to build. Now I don't need to... – Jens Törnell Commented Jun 12, 2012 at 18:23
    • @ChipBennett How can update Wordpress from the outside be too localized? Many people have done that. Just not that many people show their code like InfiniteWP. – Jens Törnell Commented Jun 12, 2012 at 18:25

    Reset to default 2

    A hint to the functions that I need to use.

    I'm not sure why you'll want to mimic WP's default behavior, but most of the update logic lies on wp-admin/update-core.php

    Check for do_core_upgrade().

    The trigger function for core update seems to be wp_update_core(), which calls Core_Upgrader class (source).
