WordPress version WordPress Rating WordPress Downloads

Welcome to the Plausible Analytics WordPress Plugin GitHub repository. This is the code source and the center of active development. Here you can browse the source, look at open issues, and contribute to the project.

Getting Started

If you're looking to contribute or actively develop on Plausible Analytics then skip ahead to the Local Development section below. The following is if you're looking to actively use the plugin on your WordPress site.

Minimum Requirements

WordPress 5.3 or greater
PHP version 7.4 or greater
MySQL version 5.5 or greater

Automatic installation

Automatic installation is the easiest option as WordPress handles the file transfers itself, and you don't need to leave your web browser. To do an automatic installation of Plausible Analytics, log in to your WordPress dashboard, navigate to the Plugins menu and click "Add New".

In the search field type "Plausible Analytics" and click Search Plugins. Once you have found the plugin you can view details about it such as the point release, rating and description. Most importantly of course, you can install it by simply clicking "Install Now".

Manual installation

The manual installation method involves downloading our plugin and uploading it to your server via your favorite FTP application. The WordPress codex contains instructions on how to do this.

Available Actions, Filters and Toggles

Filters

plausible_analytics_settings: Allows you to modify and/or force values for each of the plugin's settings.
plausible_load_js_in_footer: Allows you to load the JS code snippet in the footer.
plausible_analytics_script_params: Allows you to modify the script element, loading the Plausible JS library.
- Example: using this filter and the file-types attribute will allow you to track downloads of certain file types when File Downloads tracking is enabled.
plausible_analytics_pageview_properties: Allows you to add custom pageview properties when the Pageview Properties option is enabled under Enhanced Measurements. For examples, read the documentation on Pageview Properties.

Actions

plausible_analytics_settings_saved: Trigger additional tasks directly after settings are saved.
plausible_analytics_after_register_assets: This action allows you to trigger additional tasks or add custom JS (e.g. events) to the tracking code.

Toggles

Using constants, you can modify the behavior of the plugin. wp-config.php is the best place to define constants. If you're using a custom plugin, make sure its code is loaded before this plugin.

PLAUSIBLE_SELF_HOSTED_DOMAIN: Especially useful for Multisite instances using the self-hosted version of Plausible, this constant allows you to specify the Self-Hosted Domain for all subsites at once. IMPORTANT: this constant takes precedence over the plugin's setting. So, if this constant is defined, changing the setting won't have any effect.
plausible_proxy: Appending this GET-parameter will force enable the proxy on the page you\'re calling it. This will allow you to test your proxy in the frontend, before enabling the option.

Local Development

To get started developing on the Plausible Analytics WordPress Plugin you will need to perform the following steps:

Create a new WordPress site with plausible.test as the URL
cd into your local plugins directory: /path/to/wp-content/plugins/
Clone this repository from GitHub into your plugins directory: https://github.com/plausible/wordpress.git
Run composer to set up dependencies: composer install
Run npm install to get the necessary npm packages: npm install
Activate the plugin in WordPress

That's it. You're now ready to start development.

NPM Commands

Plausible Analytics relies on several npm commands to get you started:

npm run watch - Live reloads JS and SASS files. Typically, you'll run this command before you start development. It's necessary to build the JS/CSS however if you're working strictly within PHP it may not be necessary to run.
npm run dev - Runs a one time build for development. No production files are created.
npm run production - Builds the minified production files for release.

Development Notes

Ensure that you have SCRIPT_DEBUG enabled within your wp-config.php file. Here's a good example of wp-config.php for debugging:

 // Enable WP_DEBUG mode
define( 'WP_DEBUG', true );

// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );

// Loads unminified core files
define( 'SCRIPT_DEBUG', true );

Commit the package.lock file. Read more about why here.
Your editor should recognize the .eslintrc and .editorconfig files within the Repo's root directory. Please only submit PRs following those coding style rulesets.

Regenerating the OpenAPI PHP Client

This plugin uses a OpenAPI PHP Client which is autogenerated by the OpenAPI generator to reduce contract violations, etc. to a minimum. But, since this is a WordPress plugin, some manual modifications need to be done to make sure it doesn't conflict with other plugins:

(Re)generate the PHP client using the following command (trigger it from the Plugin's root dir as output will be saved to src/Client): openapi-generator-cli generate -i https://plausible.io/api/plugins/spec/openapi -g php -o src/Client --additional-properties=identifierNamingConvention=snake_case,invokerPackage="Plausible\\Analytics\\WP\\Client" --global-property=apis,models,supportingFiles,modelDocs=false,modelTests=false,apiDocs=false,apiTests=false
(When regenerating the PHP client this step can be skipped) Navigate to the src/Client director and install Composer dependencies: composer install --no-dev
(When regenerating the PHP client this step can be skipped) Run mozart compose from the src/Client directory (Make sure Mozart is installed globally)
In the src/Client/lib directory, replace all occurrences of GuzzleHttp (mind the space) with Plausible\Analytics\WP\Client\Lib\GuzzleHttp ( again, mind the space at the beginning)
In the same directory, replace all occurrences of \GuzzleHttp (mind the space and backslash) with \Plausible\Analytics\WP\Client\Lib\GuzzleHttp.
If escaping characters doesn't work in your bash instance, you might also have to replace PlausibleAnalyticsWPClient with Plausible\Analytics\WP\Client.
