Can we define variables in `.tpl` files?

Question

In general, if we have a Smarty project we assign variables in .php file, and use the variables in its corresponding .tpl` file.

such as:

$smarty->assign('foo', 'Foo');  // in .php file

{$foo}  // in .tpl file

can we define the variables in .tpl? and if can, is this recommend? and why?

Answer 1

Yes, you can:

{assign var="foo" value="Foo"}
{assign "foo" "Foo"} {* short-hand *}

The value of $foo is Foo.
