- {foreach}循环也有自身属性的变量，可以通过{$smarty.foreach.name.property}访问，其中"name"是name属性。
Note: The name attribute is only required when you want to access a
{foreach} property, unlike {section}. Accessing a {foreach} property with
name undefined does not throw an error, but leads to unpredictable results instead.
注意：name属性仅在需要访问{foreach}属性时有效，与{section}不同。访问未定义name的{foreach}属性不会抛出一个错误，但将导致不可预知的结果。
- {foreach} properties are index, iteration,
first, last, show, total. - {foreach}属性有index, iteration, first, last, show, total.
Example 7-5. The item attribute例 7-5. item属性
<?php
$arr= array(1000, 1001, 1002);
$smarty->assign('myArray',$arr);
?>Template to output $myArray in an un-ordered list
用模板以无序列表输出$myArray
<ul> {foreach from=$myArray item=foo} <li>{$foo}</li> {/foreach} </ul>The above example will output:
上例将输出：
<ul> <li>1000</li> <li>1001</li> <li>1002</li> </ul>
Example 7-6. Demonstrates the item and key attributes例 7-6. 演示item和key属性
<?php
$arr= array(9 => 'Tennis', 3 => 'Swimming', 8 => 'Coding');
$smarty->assign('myArray',$arr);
?>Template to output $myArray as key/val pair, like PHP's foreach.
用模板按键名/键值对的形式输出$myArray, 类似于PHP的foreach。
<ul> {foreach from=$myArray key=k item=v} <li>{$k}: {$v}</li> {/foreach} </ul>The above example will output:
上例将输出：
<ul> <li>9: Tennis</li> <li>3: Swimming</li> <li>8: Coding</li> </ul>
Example 7-7. {foreach} with associative item attribute例 7-7. {foreach}的item属性是关联数组
<?php
$items_list= array(23 => array('no' => 2456, 'label' => 'Salad'),
96 => array('no' => 4889, 'label' => 'Cream')
);
$smarty->assign('items',$items_list);
?>Template to output $items with $myId in the url
模板中，url通过$myId输出$items
<ul> {foreach from=$items key=myId item=i} <li><a href="item.php?id={$myId}">{$i.no}: {$i.label}</li> {/foreach} </ul>The above example will output:
上例将输出：
<ul> <li><a href="item.php?id=23">2456: Salad</li> <li><a href="item.php?id=96">4889: Cream</li> </ul>
Example 7-8. {foreach} with nested item and key例 7-8. {foreach}使用嵌套的item和key
Assign an array to Smarty, the key contains the key for each looped value.
向Smarty设置一个数组，对于每个键名对应的每个循环值都包括键。
<?php
$smarty->assign('contacts', array(
array('phone' => '1',
'fax' => '2',
'cell' => '3'),
array('phone' => '555-4444',
'fax' => '555-3333',
'cell' => '760-1234')
