Example text

If each string of user-entered text is stored in its own variable, and the variables are declared using the contributed Variable module’s hook_variable_info(), site builders can use the contributed Internationalization module to translate this text. This is most appropriate if you just have a few administrator-entered text strings that need to be translated. • For settings that form a list, use a Drupal core taxonomy vocabulary to manage the list instead of managing it in your own module. The taxonomy terms can then be translated using the contributed Internationalization module.

You can take advantage of the internationalization and translation capabilities of built-in Drupal systems. Here are some examples of Drupal site building knowledge you should explore in order to avoid unnecessary and tedious programming: Customizing fielded content display The core Fields administrative interface provides a lot of flexibility in defining how fields are displayed in content, including the order of fields, label placement, data formatting, and which fields are shown. If that is not enough, the Display Suite module can be helpful as can the Panels module.

For instance, the core Node module provides hooks that allow other modules to define permission systems for node content, which can be as simple as “Only allow users of role A to view node content of type B,” or as complex as allowing access to particular node content items only to certain individual users. If you are writing a module that allows users to operate or view node content, you need to respect whatever permissions other modules may have defined. Similarly, if you are writing a module that deals with core taxonomy terms, comments, or content managed by a contributed module, you need to make sure that your module is complying with the content permission scheme that applies.
