1. Smarty
Mustafa Kırımlı

2. Smarty Basics
{* this is a comment *}
{* this multiline smarty
comment is
not sent to browser
*}
{* The header file with the main logo and stuff *}
{include file='header.tpl'}
{* Dev note: the $includeFile var is assigned in foo.php script *}
<!-- Displays main content block -->
{include file=$includeFile}

3. Smarty Access Variables
{$foo}
<-- displaying a simple variable (non array/object)
{$foo[4]} <-- display the 5th element of a zero-indexed array
{$foo.bar} <-- display the "bar" key value of an array, similar to PHP $foo['bar']
{$foo.$bar} <-- display variable key value of an array, similar to PHP $foo[$bar]
{$foo->bar} <-- display the object property "bar"
{$foo->bar()} <-- display the return value of object method "bar"
{#foo#}
<-- display the config file variable "foo"
{$smarty.config.foo} <-- synonym for {#foo#}
{$foo[bar]} <-- syntax only valid in a section loop, see {section}
{assign var=foo value='baa'}{$foo} <-- displays "baa", see {assign}

4. Smarty Access Variables
{$foo.bar.baz}
{$foo.$bar.$baz}
{$foo[4].baz}
{$foo[4].$baz}
{$foo.bar.baz[4]}
{$foo->bar($baz,2,$bar)} <-- passing parameters
{"foo"}
<-- static values are allowed
PHP-like syntax, alternative to "dot" syntax:
{$foo[1]}
// normal access
{$foo['bar']}
{$foo['bar'][1]}
{$foo[$x+$x]}
// index may contain any expression
{$foo[$bar[1]]}
// nested index
{$foo[section_name]} // smarty {section} access, not array access!

5. Smarty PHP Variables
{* display the server variable "SERVER_NAME" ($_SERVER['SERVER_NAME'])*}
{$smarty.server.SERVER_NAME}
Object chaining:
{$object->method1($x)->method2($y)}
Direct PHP function access:
{time()}
<?php define('MY_CONST_VAL','CHERRIES'); // the constant defined in php ?>
{$smarty.const.MY_CONST_VAL}

6. Smarty Superglobals
{* display value of page from URL ($_GET) http://www.example.com/index.php?page=foo *}
{$smarty.get.page}
{* display the variable "page" from a form ($_POST['page']) *}
{$smarty.post.page}
{* display the value of the cookie "username" ($_COOKIE['username']) *}
{$smarty.cookies.username}
{* display the server variable "SERVER_NAME" ($_SERVER['SERVER_NAME'])*}
{$smarty.server.SERVER_NAME}
{* display the system environment variable "PATH" *}
{$smarty.env.PATH}
{* display the php session variable "id" ($_SESSION['id']) *}
{$smarty.session.id}
{* display the variable "username" from merged get/post/cookies/server/env *}
{$smarty.request.username}

7. Smarty {literal}
<script>
// the following braces are ignored by Smarty
// since they are surrounded by whitespace
function foobar {
alert('foobar!');
}
// this one will need literal escapement
{literal}
function bazzy {alert('foobar!');}
{/literal}
</script>

8. Smarty {php}
{* this template includes a {php} block that assign's the variable $varX
*}
{php}
global $foo, $bar;
if($foo == $bar){
echo 'This will be sent to browser';
}
// assign a variable to Smarty
$this->assign('varX','Toffee');
{/php}
{* output the variable *}
<strong>{$varX}</strong> is my fav ice cream :-)

9. Smarty |replace
<?php
$smarty->assign('articleTitle', "Child's Stool Great for Use in Garden.");
?>
Smarty:
{$articleTitle}
{$articleTitle|replace:'Garden':'Vineyard'}
{$articleTitle|replace:' ':' '}
Output:
Child's Stool Great for Use in Garden.
Child's Stool Great for Use in Vineyard.
Child's Stool Great for Use in Garden.

10. Smarty |truncate
<?php
$smarty->assign('articleTitle', 'Two Sisters Reunite after Eighteen Years at Checkout Counter.');
?>
{$articleTitle}
{$articleTitle|truncate}
{$articleTitle|truncate:30}
{$articleTitle|truncate:30:""}
{$articleTitle|truncate:30:"---"}
{$articleTitle|truncate:30:"":true}
{$articleTitle|truncate:30:"...":true}
{$articleTitle|truncate:30:'..':true:true}

<tr bgcolor="#dddddd"><td>5</td><td>6</td><td>7</td><td>8</td></tr>
<tr bgcolor="#eeeeee"><td>9</td><td>&nbsp;</td><td>&nbsp;</td><td>&nbsp;</td></tr>

);
$smarty->assign('mySelect', 9904);
?>
Smarty:
{html_options name=foo options=$myOptions selected=$mySelect}

<option value="9904" selected="selected">Jack Smith</option>
<option value="2003">Charlie Brown</option>
</select>
