Expression Engine i18n

Does Expression Engine have a built-in solution for i18n (internationalization)?

I have to bui开发者_如何学Gold a multi-language site, and would like to know the best approaches in EE for doing so.

There are many ways you can create a multilingual or country-specific site in ExpressionEngine to deliver content specific to each language/country.

The two most popular solutions are summarized from the following ExpressionEngine Wiki articles:

MultiLingual Websites in ExpressionEngine

The basic idea is to present your content in different languages using a combination of URL Segments, custom fields and a bit of PHP.

Advantages

• Single entry manages multiple languages
• Simple URL structure

As an example, say you have a 3-language site: English (en), Spanish (es) and German (de).

For every piece of content in your site, you'd create a custom field with the language identifier as a postfix (or prefix, whatever you prefer) to the fields.

Your custom field names might look like this:

custom_field_en
custom_field_es
custom_field_de

To switch between languages, simply add a corresponding URL segment (/en, /es or /de) that matches the language:

example.com/template_group/template/en
example.com/template_group/template/es
example.com/template_group/template/de

The main advantage of this approach is that it keeps all versions of your content inside a single entry, making updates and edits easy and consistent.

MultiLingual Websites in ExpressionEngine, Alternative

The alternative approach idea is to create sub-directories for each country, and use ExpressionEngine's path.php Global Variables to hold the country code and/or language as a variable.

Advantages

• No PHP needed
• No need to keep track of which segment holds the language variable
• Elegant URL structure

Using the same 3-languages as an example from the first method, you would create a new directory in the root of your EE install and name it after the country code of the language you want to add:

Your folder structure might look like this:

+ /de
+ /en
+ /es
index.php
+ /images
+ /system
+ /themes

To allow this method work, place a copy of the main index.php inside each of the language directories. You would then modify each file by assigning variables corresponding to each language's directory:

$assign_to_config['site_index'] = 'http://www.example.com/en/';
$assign_to_config['global_vars'] = array(
    "country_code" => "en",
    "language" => "english"
);

The URLs built will use whatever language/country designation you choose:

example.com/es-MX/template_group/template/
example.com/MX/template_group/template/

The main advantage of the alternative approach is using Global Variables, leveraging the fact they are are parsed very early, and can be used almost anywhere in templates.

Other Solutions

Embracing the philosophy of ExpressionEngine, the flexibility you're given as a designer/developer allows you to tailor a custom solution that suits your unique needs.

If either of these approaches don't quite meet your needs, you can eaily craft your own method or take a hybrid approach.

With this in mind, a good starting point would be to look into the Multilingual Add-Ons at Devot-ee that may aide in your development.
