Methods

__construct()

Constructor.

Since: 2.3.0
Line: 31

public function __construct(  );

load_plugin_textdomain() static

Initialises text domain for l10n.

Since: 2.3.0
Line: 43

static public function load_plugin_textdomain(  ): void;

Returns: void

get_translated_term_id() static

Translate a term ID to the current language.

Widget and shortcode settings store the term ID saved by the admin in the default language. On a non-default-language page the stored ID must be resolved to the equivalent term in the current language before use.

Since: 3.0.0
Line: 60

static public function get_translated_term_id( int $term_id, string $taxonomy ): int;

Returns: int — Translated term ID, or the original if no translation exists.

get_current_language() static

Return the current language slug, or an empty string when no multilingual plugin is active.

Since: 3.0.0
Line: 86

static public function get_current_language(  ): string;

Returns: string — Language slug (e.g. ‘en’, ‘fr’) or ‘’ if not multilingual.

is_translatepress_active() static

Whether TranslatePress is active and exposes the API this integration needs.

Since: 3.1.5
Line: 105

static public function is_translatepress_active(  ): bool;

Returns: bool — True if TranslatePress can be used.

get_trp_component() static

Fetch a TranslatePress component instance.

Since: 3.1.5
Line: 117

static public function get_trp_component( string $component ): object|null;

Returns: object|null — Component instance or null when unavailable.

get_trp_settings() static

Get the TranslatePress settings array.

Since: 3.1.5
Line: 139

static public function get_trp_settings(  ): array;

Returns: array — TranslatePress settings.

get_trp_current_language() static

Get the TranslatePress language the current front-end request is rendering in.

Since: 3.1.5
Line: 153

static public function get_trp_current_language(  ): string;

Returns: string — Language code, or an empty string when TranslatePress is inactive

get_cache_language() static

Get a language identifier for cache keys.

Rendered output is language-specific — TranslatePress filters home_url(), and WPML/Polylang resolve different post IDs — so cached HTML and post lists must not be shared between languages.

Since: 3.1.5
Line: 178

static public function get_cache_language(  ): string;

Returns: string — Current language code, or an empty string when the site is monolingual.

get_trp_rest_language() static

Resolve the TranslatePress language a REST request should be rendered in.

TranslatePress derives the language from the page URL, but REST routes carry no language prefix, so the language is taken from an explicit lang parameter and falls back to the referring front-end URL.

Since: 3.1.5
Line: 238

static public function get_trp_rest_language( $request = ... ): string;

Returns: string — Language code, or an empty string when no translation is needed.

get_trp_ajax_language() static

Resolve the TranslatePress language for an admin-ajax request.

Since: 3.1.5
Line: 313

static public function get_trp_ajax_language(  ): string;

Returns: string — Language code, or an empty string when no translation is needed.

trp_translate_content() static

Translate a string with TranslatePress.

Since: 3.1.5
Line: 330

static public function trp_translate_content( string $content, string $language ): string;

Returns: string — Translated content.

trp_translate_url() static

Convert a URL to its TranslatePress equivalent in the given language.

Since: 3.1.5
Line: 348

static public function trp_translate_url( string $url, string $language ): string;

Returns: string — Converted URL.

translate_rest_response() static

Translate the Knowledge Base REST API response with TranslatePress.

TranslatePress’s own page output buffer never runs for REST requests, so the output returned over REST would otherwise always be served in the default language.

Since: 3.1.5
Line: 378

static public function translate_rest_response( $result, $server, $request ): mixed;

Returns: mixed — Response data, translated where applicable.
