Content::localize()

\nn\t3::Content()->localize(`$table = 'tt_content', $data = [], $localize = true`);

Localize / translate data.

Examples:

Translate data using the current language of the frontend.

\nn\t3::Content()->localize( 'tt_content', $data );

Get data in a DIFFERENT language than the one set in the frontend. Takes into account the fallback chain of the language that was set in the site config

\nn\t3::Content()->localize( 'tt_content', $data, 2 );

Get data with own fallback chain. Completely ignores the chain, that was defined in the site config.

\nn\t3::Content()->localize( 'tt_content', $data, [3, 2, 0] );

    @param string $table Database table

    @param array $data Array with the data of the default language (languageUid = 0)

    @param mixed $localize Specification of how to translate. Boolean, uid or array with uids

    @return array
