wpml_object_id

apply_filters( 'wpml_object_id', int $element_id, string $element_type, bool $return_original_if_missing, mixed $ulanguage_code )

类型: filter
类别: 获取本地化内容
WPML 版本: 3.2

说明

返回当前语言或其他指定语言中某个元素的 ID。

默认情况下，WPML 会自动调整 ID，以在当前语言中显示所有主题元素。此设置默认在 WPML → 语言页面下处于“开启”状态。但是，如果您从头开始构建自己的主题，请使用 wpml_object_id 函数手动调整 ID。这种方法在处理方面更高效。

参数

$element_id: (int) (必填) 要筛选的文章类型（post、page、attachment、custom post）或分类法术语（tag、category、custom taxonomy）的 ID
$element_type: (string) (必填) 该 ID 所属的元素类型。可以是 post、page、{custom post type key}、nav_menu、nav_menu_item、category、post_tag、{custom taxonomy key}
$return_original_if_missing: (bool) (可选) 如果设置为 true，将始终返回一个值（如果缺失翻译，则返回原始值）。默认为 FALSE
$ulanguage_code: (mixed) (可选) 如果缺失或为 NULL，将使用当前语言。如果设置为语言代码，将返回该语言代码的翻译；如果缺失翻译且 $return_original_if_missing 设置为 TRUE，则返回原始值。默认为 NULL

使用示例

一些基本示例

// will return the post ID in the current language for post ID 1
echo apply_filters( 'wpml_object_id', 1, 'post' );

// will return the category ID in the current language for categoy ID 4. If the translation is missing it will return the original (here: category ID 4)
echo apply_filters( 'wpml_object_id', 4, 'category', TRUE  );

// will return the German attachment ID for attachment ID 25. If the translation is missing it will return NULL
echo apply_filters( 'wpml_object_id', 25, 'attachment', FALSE, 'de' );
