Compiler Functions
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.
mixed smarty_compiler_
name
(string $tag_arg, object &$smarty)
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.

Пример 16-6. simple compiler function
<?php
/*
* Smarty plugin
* -------------------------------------------------------------
* File: compiler.tplheader.php
* Type: compiler
* Name: tplheader
* Purpose: Output header containing the source file name and
* the time it was compiled.
* -------------------------------------------------------------
*/
function smarty_compiler_tplheader($tag_arg, &$smarty)
{
return "\necho '" . $smarty->_current_file . " compiled at " . date('Y-m-d H:M'). "';";
}
?>
|
This function can be called from the template as:
{* this function gets executed at compile time only *}
{tplheader}
|
The resulting PHP code in the compiled template would be something like this:
<php
echo 'index.tpl compiled at 2002-02-20 20:02';
?>
