## 外掛說明

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](https://wordpress.org/plugins/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](https://profiles.wordpress.org/ipstenu)
> during the [contributors day at WordCamp Europe 2016](https://2016.europe.wordcamp.org/introducing-the-wceu-2016-contributor-day-and-workshops/).

#### Important

This plugin requires the [Debug Bar](https://wordpress.org/plugins/debug-bar/) plugin
to be installed and activated.

Also note that this plugin should be used solely for debugging and/or in a development
environment and is not intended for use on a production site.

If you like this plugin, please [rate and/or review](https://wordpress.org/support/view/plugin-reviews/debug-bar-plugin-activation)

## 常見問題集

  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](https://developer.wordpress.org/plugins/the-basics/activation-deactivation-hooks/)

  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.

Ref: [Plugin Handbook](https://developer.wordpress.org/plugins/the-basics/uninstall-methods/)

  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](https://developer.wordpress.org/plugins/the-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.

Just a note of thank you to the developer. And, a note to potential users, this 
still worked on my localhost dev site in helping me debug the activation error ‘
headers already sent’. The plugin allowed me to read the additional output to see
where the error was coming from and resolve it. Thanks!

### 󠀁[Excellent tool for plugin developers](https://wordpress.org/support/topic/excellent-tool-for-plugin-developers/)󠁿

 [Chad Butler](https://profiles.wordpress.org/cbutlerjr/) 2020 年 7 月 20 日

I know this plugin currently doesn’t show any updates for several versions of WordPress.
However, it continues to work just fine. I find it a necessary tool for plugin development.
It adds to the debug bar, and if there are any errors that occur during plugin activation,
you can get them in the debug bar – an essential message if you’re trying to develop
a plugin and need to debug the activation process. The plugin is an add-on to the
Debug Bar plugin, so if you don’t have that installed, it won’t work.
