⚠️ Update September 28th 2023 ⚠️

We have discontinued development on this project. If you're interested in this module, we happily refer you to a well-maintained fork by @mte90 at https://github.com/WPBP/i18n-notice.

Yoast i18n module

Promote your own translation site for people who are using your plugin in another language than en_US.

Example of the rendered promo box

The image, the name of your plugin and the name of your translation project are all configurable (see example below). The name of the language is retrieved from your GlotPress install, as is the percentage translated. The box doesn't display when a language has been translated for 90% or more.

How to use this module

Include it in your project using composer:

composer require yoast/i18n-module

Alternatively you can include the library as a submodule. Make sure the class is loaded and instantiate it like this:

new Yoast_I18n_v3(
	array(
		'textdomain'     => '{your text domain}',
		'project_slug'   => '{your probject slug}',
		'plugin_name'    => '{your plugin name}',
		'hook'           => '{the hook to display the message box on}',
		'glotpress_url'  => '{url to your glotpress installation; http://translate.yoast.com}',
		'glotpress_name' => '{name of your glotpress installation}',
		'glotpress_logo' => '{url to a logo which will be shown}',
		'register_url '  => '{url to use when registering for a project}',
	)
);

If the service you are using doesn't follow the GlotPress conventions for the URLs, you may want to pass directly the full api_url to get the list of available translations, instead of letting the class build it from glotpress_url:

new Yoast_I18n_v3(
	array(
		'textdomain'     => '{your text domain}',
		'project_slug'   => '{your probject slug}',
		'plugin_name'    => '{your plugin name}',
		'hook'           => '{the hook to display the message box on}',
		'api_url'        => '{url the JSON list of the available languages}',
		'glotpress_name' => '{name of your glotpress installation}',
		'glotpress_logo' => '{url to a logo which will be shown}',
		'register_url '  => '{url to use when registering for a project}',
	)
);

Because translate.wordpress.org is also a GlotPress installation you can use the i18n-module to promote translation your plugin on there. To do this you can use the dedicated wordpress.org class:

new Yoast_I18n_WordPressOrg_v3(
	array(
		'textdomain'  => '{your text domain}',
		'plugin_name' => '{your plugin name}',
		'hook'        => '{hook to display the message box on}',
	)
);

Customize where and when to render the message

Since 3.0.0 you can also decide to render the message in a message-box of your own, just provide the second argument to the constructor as false to disable the showing of the box by the module itself.

$i18n_module = new Yoast_I18n_v3(
	array(
		'textdomain'     => '{your text domain}',
		'project_slug'   => '{your probject slug}',
		'plugin_name'    => '{your plugin name}',
		'hook'           => '{the hook to display the message on - not used in this example}',
		'glotpress_url'  => '{url to your glotpress installation; http://translate.yoast.com}',
		'glotpress_name' => '{name of your glotpress installation}',
		'glotpress_logo' => '{url to a logo which will be shown}',
		'register_url '  => '{url to use when registering for a project}',
	),
	false
);

$message = $i18n_module->get_promo_message();

$i18n_module = new Yoast_I18n_WordPressOrg_v3(
	array(
		'textdomain'  => '{your text domain}',
		'plugin_name' => '{your plugin name}',
		'hook'        => '{hook to display the message on - not used in this example}',
	),
	false
);

$message = $i18n_module->get_promo_message();
