Example 7.30. A simple {foreach} loop

<?php
$arr = array('red', 'green', 'blue');
$smarty->assign('myColors', $arr);
?>

Template to output $myColors in an un-ordered list

<ul>
{foreach $myColors as $color}
    <li>{$color}</li>
{/foreach}
</ul>

The above example will output:

<ul>
    <li>red</li>
    <li>green</li>
    <li>blue</li>
</ul>

----------------------------------------------------------

Example 7.31. Demonstrates the an additional key variable

<?php
$people = array('fname' => 'John', 'lname' => 'Doe', 'email' => 'j.doe@example.com');
$smarty->assign('myPeople', $people);
?>

Template to output $myArray as key/value pairs.

<ul>
{foreach $myPeople as $value}
   <li>{$value@key}: {$value}</li>
{/foreach}
</ul>

The above example will output:

<ul>
    <li>fname: John</li>
    <li>lname: Doe</li>
    <li>email: j.doe@example.com</li>
</ul>

Example 7.33. Database example with {foreachelse}

<?php 
  include('Smarty.class.php'); 

  $smarty = new Smarty; 

  $dsn = 'mysql:host=localhost;dbname=test'; 
  $login = 'test'; 
  $passwd = 'test'; 

  // setting PDO to use buffered queries in mysql is 
  // important if you plan on using multiple result cursors 
  // in the template. 

  $db = new PDO($dsn, $login, $passwd, array( 
     PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true)); 

  $res = $db->prepare("select * from users"); 
  $res->execute(); 
  $res->setFetchMode(PDO::FETCH_LAZY); 

  // assign to smarty 
  $smarty->assign('res',$res); 

  $smarty->display('index.tpl');?>
?>

{foreach $res as $r} 
  {$r.id} 
  {$r.name}
{foreachelse}
  .. no results .. 
{/foreach}
