Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.super-forms.com/developers/code-examples/define-page-language-attribute-based-on-page-id-or-url.md). # Define page language attribute based on page ID or URL {% hint style="info" %} **Note:** The below filter hook is only useful whenever you are not using a translation plugin {% endhint %} When you are not using any language plugin to translate your website but still want to have a specific page in a different language (other than your main site language), you will have to change the `` language attribute based on the current page URL. This is important so that whenever a user visits a page that is different from your main site language the browser won't try to translate the page (again) including your form. Let's say your site is in English by default, but you also have a translated version of your form in Deutsch and French. When the user visists the page `/de/contact` or `/fr/contact` the browser will still think that the page is in your main language (English) because the language attribute would still be set to `en`. This can cause unexpected translations being done by the browser. The only way to avoid this is to make sure the correct language attribute for these pages is set accordingly. A filter hook on how to do this can be found below. ```php function f4d_language_attributes($lang){ if(strpos(get_permalink(), home_url().'/de/')!==false){ // When user is on the German site return "lang=\"de-DE\""; } if(strpos(get_permalink(), home_url().'/fr/')!==false){ // When user is on the French site return "lang=\"fr-FR\""; } if(get_permalink()===home_url().'/specific-url-in-deutch/'){ // When on a Deutsch page return "lang=\"de-DE\""; } if(get_permalink()===home_url().'/specific-url-in-french/'){ // When on a French page return "lang=\"fr-FR\""; } // Return default language attribute return $lang; } add_filter('language_attributes', 'f4d_language_attributes'); ``` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.super-forms.com/developers/code-examples/define-page-language-attribute-based-on-page-id-or-url.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
