The module "common" is kind of a special one in ZenTao modules. Many common functions in ZenTao are implemented by the module "common".
- You can find some methods that other modules may use in common/model.php, such as permission checking, menu printing, and so on.
- You can find the public templates in common/view, such as the public header.html.php, footer.html.php, and etc. It also contains initialization code templates for various jQuery plugins such as colorbox.html.php.
- You can find the public language items in common/lang.
As a conclusion, if you need to change some language items or change the common template files later, you can find the corresponding code under the common module.
