- {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')
));
?>
The template to output $contact.
用于输出$contact的模板。{foreach name=outer item=contact from=$contacts} <hr /> {foreach key=key item=item from=$contact} {$key}: {$item}<br /> {/foreach} {/foreach}
The above example will output:
上例将输出:<hr /> phone: 1<br /> fax: 2<br /> cell: 3<br /> <hr /> phone: 555-4444<br /> fax: 555-3333<br /> cell: 760-1234<br />
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,<?php
$search_condition = "where name like '$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=$results} <a href="contact.php?contact_id={$cid}">{$con.name} - {$con.nick}</a><br /> {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
|
.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
|
.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
|
.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
|
.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
