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

&lt;?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-&gt;_current_file . " compiled at " . date('Y-m-d H:M'). "';";
}
?&gt;

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';
?>
