例 7-5. item属性
- $arr = array("http://www.phpzy.com", "www.phpzy.com", "绿色php资源");
- $smarty->assign('myArray', $arr);
- ?>
Template to output $myArray in an un-ordered list
用模板以无序列表输出$myArray
- {foreach from=$myArray item=foo}
- {$foo}
- {/foreach}
The above example will output:
上例将输出：
Example 7-6. Demonstrates the item and key attributes
例 7-6. 演示item和key属性
$arr = array(9 => 'T', 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。
- {foreach from=$myArray kkey=k item=v}
- {$k}: {$v}
- {/foreach}
The above example will output:
上例将输出：
- 9: Tennis
- 3: Swimming
- 8: Coding
Example 7-7. {foreach} with associative item attribute
例 7-7. {foreach}的item属性是关联数组
$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
The above example will output:
上例将输出：
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。
$smarty->assign('contacts', array(
array('phone' => '1',
'fax' => '2',
'cell' => '3'),
array('phone' => '555-4444',
'fax' => '555-3333',
'cell' => '760-1234')
));
?>
The template to output $contact.
用于输出$contact的模板。
- {foreach name=outer item=contact from=$contacts}
- {foreach key=key item=item from=$contact}
- {$key}: {$item}
- {/foreach}
- {/foreach}
The above example will output:
上例将输出：
- phone: 1
- fax: 2
- cell: 3
- phone: 555-4444
- fax: 555-3333
- cell: 760-1234
Example 7-9. Database example with {foreachelse}
例 7-9. 使用{foreachelse}的数据库示例
A database (eg PEAR or ADODB) example of a search script, the query results assigned to Smarty
一个数据库（例如PEAR或ADODB）的搜索脚本示例，
$search_condition = "where name like '$foo%' ";
$sql = 'select contact_id, name, nick from contacts '.$search_condition.' order by name';
$smarty->assign('results', $db->getAssoc($sql) );
?>
The template which display "None found" if no results with {foreachelse}.
借助{foreachelse}标记在没有结果时模板输出"None found"字样。
- {foreach key=cid item=con from=$results}
- {$con.name} - {$con.nick}
- {foreachelse}
- No items were found in the search
- {/foreach}
.index
index contains the current array index, starting with zero.
.index包含当前数组索引，从零开始。
Example 7-10. index example
例 7-10. index示例
{* The header block is output every five rows *}
{* 每五行输出一次头部区块 *}
{foreach from=$items key=myId item=i name=foo}
{if $smarty.foreach.foo.index % 5 == 0}
{/if}
{/foreach}
| Title |
|---|
| {$i.label} |
.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}|{$smarty.foreach.foo.iteration},
{/foreach}
.first
first is TRUE if the current {foreach} iteration is the initial one.
first在当前{foreach}循环处于初始位置时值为TRUE。
Example 7-12. first property example
例 7-12. first属性示例
{* show LATEST on the first item, otherwise the id *}
{* 对于第一个条目显示LATEST而不是id *}
{foreach from=$items key=myId item=i name=foo}
{/foreach}
| {if $smarty.foreach.foo.first}LATEST{else}{$myId}{/if} | {$i.label} |
.last
last is set to TRUE if the current {foreach} iteration is the final one.
last在当前{foreach}循环处于最终位置是值为TRUE。
Example 7-13. last property example
例 7-13. last属性示例
{* Add horizontal rule at end of list *}
{* 在列表结束时增加一个水平标记 *})
{foreach from=$items key=part_id item=prod name=products}
{$prod}{if $smarty.foreach.products.last}
{else},{/if}
{foreachelse}
... content ...
{/foreach}
.show
show is used as a parameter to {foreach}. show is a boolean value. If FALSE, the{foreach} will not be displayed. If there is a {foreachelse} present, that will be alternately displayed.
show是{foreach}的参数. show是一个布尔值。如果值为FALSE，{foreach}将不被显示。如果有对应的{foreachelse}，将被显示。
.total
total contains the number of iterations that this {foreach} will loop. This can be used inside or after the {foreach}.
total包括{foreach}将循环的次数，既可以在{foreach}中使用，也可以在之后使用。
Example 7-14. total property example
例 7-14. total属性示例
{* show rows returned at end *}
{* 在结束位置显示行数 *}
{foreach from=$items key=part_id item=prod name=foo}
{$prod.name>
{if $smarty.foreach.foo.last}
{$smarty.foreach.foo.total} items
{/if}
{foreachelse}
... something else ...
{/foreach}
