This is the directory or directories where Smarty will look for the
plugins that it needs. Default is
plugins/ under the
SMARTY_DIR.
If you supply a relative path, Smarty will first look under the
SMARTY_DIR, then
relative to the current working directory, then relative to the PHP
include_path. If $plugins_dir
is an array of directories, Smarty will
search for your plugin in each plugin directory
in the order they are given.
Technical Note
For best performance, do not setup your $plugins_dir
to have to use the PHP include path. Use an absolute pathname,
or a path relative to SMARTY_DIR or the current
working directory.
Example 12.1. Appending a local plugin dir
<?php
$smarty->plugins_dir[] = 'includes/my_smarty_plugins';
?>
Example 12.2. Multiple $plugins_dir
<?php
$smarty->plugins_dir = array(
'plugins', // the default under SMARTY_DIR
'/path/to/shared/plugins',
'../../includes/my/plugins'
);
?>
