display() -- displays the template

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.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);
  
$smarty->assign($db_data);

}

// display the output
$smarty->display("index.tpl");
?>

Use the syntax for template resources to display files outside of the $template_dir directory.

Example 13-2. function display() template resource examples

<?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');
?>
