-Variable scopes {#language.variable.scopes}
-===============
-
-You have the choice to assign variables to the scope of the main Smarty
-object, data objects created with [`createData()`](#api.create.data),
-and template objects created with
-[`createTemplate()`](#api.create.template). These objects can be
-chained. A template sees all the variables of its own object and all
-variables assigned to the objects in its chain of parent objects.
-
-By default templates which are rendered by
-[`$smarty->display(...)`](#api.display) or
-[`$smarty->fetch(...)`](#api.fetch) calls are automatically linked to
-the Smarty object variable scope.
-
-By assigning variables to individual data or template objects you have
-full control which variables can be seen by a template.
-

-
- // assign variable to Smarty object scope
- $smarty->assign('foo','smarty');
-
- // assign variables to data object scope
- $data = $smarty->createData();
- $data->assign('foo','data');
- $data->assign('bar','bar-data');
-
- // assign variables to other data object scope
- $data2 = $smarty->createData($data);
- $data2->assign('bar','bar-data2');
-
- // assign variable to template object scope
- $tpl = $smarty->createTemplate('index.tpl');
- $tpl->assign('bar','bar-template');
-
- // assign variable to template object scope with link to Smarty object
- $tpl2 = $smarty->createTemplate('index.tpl',$smarty);
- $tpl2->assign('bar','bar-template2');
-
- // This display() does see $foo='smarty' from the $smarty object
- $smarty->display('index.tpl');
-
- // This display() does see $foo='data' and $bar='bar-data' from the data object $data
- $smarty->display('index.tpl',$data);
-
- // This display() does see $foo='data' from the data object $data
- // and $bar='bar-data2' from the data object $data2
- $smarty->display('index.tpl',$data2);
-
- // This display() does see $bar='bar-template' from the template object $tpl
- $tpl->display(); // or $smarty->display($tpl);
-
- // This display() does see $bar='bar-template2' from the template object $tpl2
- // and $foo='smarty' form the Smarty object $foo
- $tpl2->display(); // or $smarty->display($tpl2);
