<para>
|
|
Compiler functions are called only during compilation of the template.
|
|
They are useful for injecting PHP code or time-sensitive static
|
|
content into the template. If there is both a compiler function and a
|
|
custom function registered under the same name, the compiler function
|
|
has precedence.

The compiler function is passed two parameters: the tag argument
|
|
string - basically, everything from the function name until the ending
|
|
delimiter, and the Smarty object. It's supposed to return the PHP code
|
|
to be injected into the compiled template.

This function can be called from the template as:

</para>
|

<programlisting>
|

{* this function gets executed at compile time only *}

{tplheader}

</programlisting>

<para>

The resulting PHP code in the compiled template would be something like this:
