Core Control Plugin Page: Core Control

Please Note: Core Control is mainly a developers plugin, however it can be used by end users alike, Just realise, That novice users are not the initial target audience, and as such, this plugin (and its modules) may be more technical aimed.

Core Control is a set of plugin modules which can be used to control certain aspects of the WordPress control.
Currently, Core Control features modules for managing Filesystem Access, Managing plugin/theme/core updates, Managing HTTP Transports & External HTTP Request logging

Filesystem Module

As of WordPress 2.5, WordPress has included a Filesystem abstraction method which allows The Plugin upgrader, Plugin Installer, Core upgrader, Theme upgrader, and soon to be, Theme Installer, the ability to modify files on the server which WordPress lies via a few methods, Direct Filesystem access (Only available to few), SSH2 (To a select few who have installed a PHP Extension) and 2 FTP methods.

This module allows You to view which Method WordPress is using, and to disable problematic methods. It also provides a small bit of path debug information, which will be expanded upon in future releases.

Upgrades Module

This module is rather simple, and ugly, In short, It allows you to Disable/Enable Core, Plugin, and Theme update checking, It also allows you to force an update to occur instantly, Useful for when you’re sure a new version has been released, but WordPress hasnt taken notice of it yet.

HTTP Module

As of WordPress 2.7, WordPress has included a new HTTP API, This simplifies the various splatterings of code used previously, everythings wrapped up together and it means that hopefully, all of WordPress’s External HTTP bugs can be located in one easy to find place..

This module Allows you to view which transports are used for what purposes (GET/POST requests), Allows you to test the transport (It requests a file hosted on my web server, and checks the response is correct), And if a module is found to not work as expected, Allows you to disable a transport.

HTTP Logging Module

The purpose of this module is to log all outgoing connections WordPress makes, It allows you to view the resulting data, as well as to view the time it has taken for each of the requests to be made.

Cron Module

This module is designed to allow you to view the WordPress Cron tasks which are currently scheduled to occur.

The Module allows you to run any task by clicking a link, and allows the cancelation of Once-Off scheduled tasks, however it is not recomended unless you are sure of what you are doing.

Future revisions of this Module will most likely allow you to configure custom tasks as well for testing purposes.

Future Modules

These are only ideas, If you’ve got one you’d like added to the list, Get in touch with me 🙂

  • Cron Module, to manage cron tasks (Much like a more basic crontool)
  • Constants module, To manage the various optional constants that you can define to control parts of WordPress (Such as revisions, etc)
  • Role module, Well.. I’m just sick of the Role Manager plugin, Considering the idea of rolling a basic manager.

  1. I am trying to install the Core Control plugin to fix an issues with a Failed connection to the FTP Server (the ‘DomainName:21’ error) so that I can disable the Transport of “PHP FTP Extension”
    …. I’ve manually copied over the core control plug-in and have created the core-control directory and modules sub-directory. I’ve activated the plug-in but when I go to tool to access the Core Control I get an error message that says ‘ Undefined variable: msg in /services/websiteos/wordpress/wp-admin/includes/update.php on line 137’. I’m not a developer so struggling with this. Any suggestions?

  2. Hi,

    I noticed that WordPress (latest version) update plugin notification seemed to have stopped working today. I knew this because I have a plugin that I did not want to upgrade to the latest version for several months now, and the nag was still showing.

    So I installed Core Control and thought it might help. But after checking for plugin updates, I get nothing, even if I have many plugins.

    “0 plugins checked, there are updates available for 0 plugin(s)”

    Any ideas ? Maybe WordPress has a problem at the moment ?


  3. Sorry, please ignore my earlier question, you can delete it. I found out that a plugin upgrade was deactivating WordPress update notification, and even Core Control can’t see any plugin.
