<para>
|
|
Each Smarty tag either prints a
|
|
<link linkend="language.variables">variable</link> or invokes some sort
|
|
of function. Functions are processed and displayed by enclosing the
|
|
function and its
|
|
<link linkend="language.syntax.attributes">attributes</link>
|
|
into delimiters like so: {funcname
|
|
attr1="val" attr2="val"}.

Both <link linkend="language.builtin.functions">built-in functions</link>
|
|
and <link linkend="language.custom.functions">custom functions</link>
|
|
have the same syntax within templates.
|
|
</para>
|
|
<para>Built-in functions are the
|
|
<emphasis role="bold">inner</emphasis> workings of Smarty, such as
|
|
<link linkend="language.function.if">{if}</link>,
|
|
<link linkend="language.function.section">{section}</link> and
|
|
<link linkend="language.function.strip">{strip}</link>.
|
|
They cannot be modified.
|
|
</para>
|
|
<para>Custom functions are <emphasis role="bold">additional</emphasis>
|
|
functions implemented via <link linkend="plugins">plugins</link>.
|
|
They can be modified to your liking, or you can add new ones.
|
|
<link linkend="language.function.html.options">{html_options}</link> and
|
|
<link linkend="language.function.popup">{popup}</link>
|
|
are examples of custom functions.
