Debug Bar Plugin Activation

Description

Ever been “greeted” when you activated a plugin with the dreaded:

This plugin generated # characters of unexpected output during activation….

And wondered what the unexpected output was ?

Or wondered whether a de-activation or uninstall routine was free of typical PHP errors ?

Well, no need to wonder anymore, as you can now see the output within your favorite debugging tool – the Debug Bar.

Debug Bar Plugin Activation adds a new panel to the Debug Bar which displays the output generated during plugin activation, deactivation and uninstall.

Once you’ve fixed the issues, you can remove the logged output straight from the Debug Bar panel.
And when you uninstall a plugin, the associated logged activation and deactivation output entries will be removed automatically.

This plugin was inspired by a conversation with Mika Epstein during the contributors day at WordCamp Europe 2016.

FAQ

Can it be used on live site ?

This plugin is only meant to be used for development purposes, but shouldn’t cause any issues if run on a production site.

What is plugin (de-)activation ?

Activation and deactivation hooks provide ways to perform actions when plugins are activated or deactivated.

Plugins can run an installation routine when they are activated in order to add rewrite rules, add custom database tables, or set default option values. … The deactivation hook is best used to clear temporary data such as caches and temp directories.

Ref: Plugin Handbook

What about uninstalling ?

Your plugin may need to do some clean-up when it is uninstalled from a site. A plugin is considered uninstalled if a user has deactivated the plugin, and then clicks the delete link.

When your plugin is uninstalled, you’ll want to clear out any rewrite rules added by the plugin, options and/or settings specific to to the plugin, or other database values that need to be removed.

How do I add activation, deactivation and uninstall routines to my plugin ?

All the information you need is in the Plugin Handbook on Plugin Basics.

Why won’t the plugin activate ?

Have you read what it says in the beautifully red bar at the top of your plugins page ? As it says there, the Debug Bar plugin needs to be active for this plugin to work. If the Debug Bar plugin is not active, this plugin will automatically de-activate itself.
