display()

Description

void display ( string template [, string cache_id [, string compile_id]])

This displays the template unlike fetch(). Supply a valid template resource type and path. As an optional second parameter, you can pass a $cache id, see the caching section for more information.

As an optional third parameter, you can pass a $compile_id. This is in the event that you want to compile different versions of the same template, such as having separate templates compiled for different languages. Another use for $compile_id is when you use more than one $template_dir but only one $compile_dir. Set a separate $compile_id for each $template_dir, otherwise templates of the same name will overwrite each other. You can also set the $compile_id variable once instead of passing this to each call to this function.

Example 13-1. display() <?php include(SMARTY_DIR.'Smarty.class.php'); $smarty = new Smarty(); $smarty->caching = true; // only do db calls if cache doesn't exist if(!$smarty->is_cached('index.tpl')) {   // dummy up some data   $address = '245 N 50th';   $db_data = array(                'City' => 'Lincoln',                'State' => 'Nebraska',                'Zip' => '68502'              );   $smarty->assign('Name', 'Fred');   $smarty->assign('Address', $address);   $smarty->assign('data', $db_data); } // display the output $smarty->display('index.tpl'); ?>

Example 13-2. Other display() template resource examples Use the syntax for template resources to display files outside of the $template_dir directory. <?php // absolute filepath $smarty->display('/usr/local/include/templates/header.tpl'); // absolute filepath (same thing) $smarty->display('file:/usr/local/include/templates/header.tpl'); // windows absolute filepath (MUST use "file:" prefix) $smarty->display('file:C:/www/pub/templates/header.tpl'); // include from template resource named "db" $smarty->display('db:header.tpl'); ?>
