{/foreach}
.index
index contains the current array index, starting with zero.
.index包含当前数组索引，从零开始。
Example 7-10. index example
例 7-10. index示例
{* The header block is output every five rows *}
{* 每五行输出一次头部区块 *}
<table>
{foreach from=$items key=myId item=i name=foo}
{if $smarty.foreach.foo.index % 5 == 0}
<tr><th>Title</th></tr>
{/if}
<tr><td>{$i.label}</td></tr>
{/foreach}
</table>.iteration
iteration contains the current loop iteration and always starts at one, unlike index. It is incremented by one on each iteration.
iteration包含当前循环次数，与index不同，从1开始，每次循环增长1。
Example 7-11. iteration and index example
例 7-11. iteration和index示例
{* this will output 0|1, 1|2, 2|3, … etc *}
{* 该例将输出0|1, 1|2, 2|3, … 等等 *}
{foreach from=$myArray item=i name=foo}
{$smarty.foreach.foo.index}|{$smarty.foreach.foo.iteration},
{/foreach}.first
first is TRUE if the current {foreach} iteration is the initial one.
first在当前{foreach}循环处于初始位置时值为TRUE。
Example 7-12. first property example
例 7-12. first属性示例
{* show LATEST on the first item, otherwise the id *}
{* 对于第一个条目显示LATEST而不是id *}
<table>
{foreach from=$items key=myId item=i name=foo}
<tr>
<td>{if $smarty.foreach.foo.first}LATEST{else}{$myId}{/if}</td>
<td>{$i.label}</td>
</tr>
{/foreach}
</table>.last
last is set to TRUE if the current {foreach} iteration is the final one.
last在当前{foreach}循环处于最终位置是值为TRUE。
Example 7-13. last property example
例 7-13. last属性示例
{* Add horizontal rule at end of list *}
{* 在列表结束时增加一个水平标记 *})
{foreach from=$items key=part_id item=prod name=products}
<a href=”#{$part_id}”>{$prod}</a>{if $smarty.foreach.products.last}<hr>{else},{/if}
{foreachelse}

{/foreach}.show
show is used as a parameter to {foreach}. show is a boolean value. If FALSE, the {foreach}will not be displayed. If there is a {foreachelse} present, that will be alternately displayed.
show是{foreach}的参数. show是一个布尔值。如果值为FALSE，{foreach}将不被显示。如果有对应的{foreachelse}，将被显示。
.total
total contains the number of iterations that this {foreach} will loop. This can be used inside or after the {foreach}.
total包括{foreach}将循环的次数，既可以在{foreach}中使用，也可以在之后使用。
Example 7-14. total property example
例 7-14. total属性示例
{* show rows returned at end *}
{* 在结束位置显示行数 *}
{foreach from=$items key=part_id item=prod name=foo}
{$prod.name><hr/>
{if $smarty.foreach.foo.last}
<div id=”total”>{$smarty.foreach.foo.total} items</div>
