Every Smarty tag either prints a
|
|
<link linkend="language.variables">variable</link> or invokes some sort
|
|
of function. These are processed and displayed by enclosing the
|
|
function and its
|
|
<link linkend="language.syntax.attributes">attributes</link>
|
|
within delimiters like so:
|
|
<literal>{funcname attr1='val1' attr2='val2'}</literal>.
