registerDefaultPluginHandler()
register a function which gets called on undefined tags
Description
===========
void
registerDefaultPluginHandler
mixed
callback
Register a default plugin handler which gets called if the compiler can
not find a definition for a tag otherwise. It uses the following
parameters:
If during compilation Smarty encounters tag which is not defined
internal, registered or loacted in the plugins folder it tries to
resolve it by calling the registered default plugin handler. The handler
may be called several times for same undefined tag looping over valid
plugin types.
<?php
$smarty = new Smarty();
$smarty->registerDefaultPluginHandler('my_plugin_handler');
/**
* Default Plugin Handler
*
* called when Smarty encounters an undefined tag during compilation
*
* @param string $name name of the undefined tag
* @param string $type tag type (e.g. Smarty::PLUGIN_FUNCTION, Smarty::PLUGIN_BLOCK,
Smarty::PLUGIN_COMPILER, Smarty::PLUGIN_MODIFIER, Smarty::PLUGIN_MODIFIERCOMPILER)
* @param Smarty_Internal_Template $template template object
* @param string &$callback returned function name
* @param string &$script optional returned script filepath if function is external
* @param bool &$cacheable true by default, set to false if plugin is not cachable (Smarty >= 3.1.8)
* @return bool true if successfull
