determine_locale ( No parameters )
determine_locale是一个WordPress的函数,它试图根据各种因素,如WPLANG常数、WP_LANG_DIR常数和网站的语言设置,来确定网站当前的地域。所得到的区域设置可以用来为网站加载适当的翻译。
确定请求所需的当前语言环境。
function determine_locale() { /** * Filters the locale for the current request prior to the default determination process. * * Using this filter allows to override the default logic, effectively short-circuiting the function. * * @since 5.0.0 * * @param string|null $locale The locale to return and short-circuit. Default null. */ $determined_locale = apply_filters( 'pre_determine_locale', null ); if ( ! empty( $determined_locale ) && is_string( $determined_locale ) ) { return $determined_locale; } $determined_locale = get_locale(); if ( is_admin() ) { $determined_locale = get_user_locale(); } if ( isset( $_GET['_locale'] ) && 'user' === $_GET['_locale'] && wp_is_json_request() ) { $determined_locale = get_user_locale(); } $wp_lang = ''; if ( ! empty( $_GET['wp_lang'] ) ) { $wp_lang = sanitize_text_field( $_GET['wp_lang'] ); } elseif ( ! empty( $_COOKIE['wp_lang'] ) ) { $wp_lang = sanitize_text_field( $_COOKIE['wp_lang'] ); } if ( ! empty( $wp_lang ) && ! empty( $GLOBALS['pagenow'] ) && 'wp-login.php' === $GLOBALS['pagenow'] ) { $determined_locale = $wp_lang; } /** * Filters the locale for the current request. * * @since 5.0.0 * * @param string $locale The locale. */ return apply_filters( 'determine_locale', $determined_locale ); }
