使用 assign() 将数组分配给 Smarty

<?php
$data = array(1000,1001,1002);
$smarty->assign('custid',$data);
?>

输出数组的模板

{* this example will print out all the values of the $custid array *}
{section name=customer loop=$custid}
{section customer $custid} {* short-hand *}
  id: {$custid[customer]}<br />
{/section}
<hr />
{*  print out all the values of the $custid array reversed *}
{section name=foo loop=$custid step=-1}
{section foo $custid step=-1} {* short-hand *}
  {$custid[foo]}<br />
{/section}

  

上述范例会输出

id: 1000<br />
id: 1001<br />
id: 1002<br />
<hr />
id: 1002<br />
id: 1001<br />
id: 1000<br />

  

{section name=foo start=10 loop=20 step=2}
  {$smarty.section.foo.index}
{/section}
<hr />
{section name=bar loop=21 max=6 step=-2}
  {$smarty.section.bar.index}
{/section}

上述范例会输出

  
10 12 14 16 18
<hr />
20 18 16 14 12 10

  

{section} 的 name 可以由你喜欢的任何内容组成，请参阅 PHP 变量。它用于引用 {section} 中的数据。

{section name=anything loop=$myArray}
  {$myArray[anything].foo}
  {$name[anything]}
  {$address[anything].bar}
{/section}

  

以下是一个使用 {section} 打印一个关联数据数组的范例。接下来是一个 PHP 脚本，用于将 $contacts 数组分配给 Smarty。

  
<?php
$data = array(
          array('name' => 'John Smith', 'home' => '555-555-5555',
                'cell' => '666-555-5555', 'email' => '[email protected]'),
          array('name' => 'Jack Jones', 'home' => '777-555-5555',
                'cell' => '888-555-5555', 'email' => '[email protected]'),
          array('name' => 'Jane Munson', 'home' => '000-555-5555',
                'cell' => '123456', 'email' => '[email protected]')
        );
$smarty->assign('contacts',$data);
?>

  

要输出 $contacts 的模板

{section name=customer loop=$contacts}
<p>
  name: {$contacts[customer].name}<br />
  home: {$contacts[customer].home}<br />
  cell: {$contacts[customer].cell}<br />
  e-mail: {$contacts[customer].email}
</p>
{/section}

  

上述范例会输出

<p>
  name: John Smith<br />
  home: 555-555-5555<br />
  cell: 666-555-5555<br />
  e-mail: [email protected]
</p>
<p>
  name: Jack Jones<br />
  home phone: 777-555-5555<br />
  cell phone: 888-555-5555<br />
  e-mail: [email protected]
</p>
<p>
  name: Jane Munson<br />
  home phone: 000-555-5555<br />
  cell phone: 123456<br />
  e-mail: [email protected]
</p>

  

此示例假定 $custid、$name 和 $address 都是包含相同数量值的数组。首先是分配数组给 Smarty 的 php 脚本。

<?php

$id = array(1001,1002,1003);
$smarty->assign('custid',$id);

$fullnames = array('John Smith','Jack Jones','Jane Munson');
$smarty->assign('name',$fullnames);

$addr = array('253 Abbey road', '417 Mulberry ln', '5605 apple st');
$smarty->assign('address',$addr);

?>

loop 变量仅决定循环次数。您可以在 {section} 中的模板中访问任何变量。这对于循环多个数组很有用。您可以传递一个数组来通过数组大小确定循环计数，或者您可以传递一个整数来指定循环数。

{section name=customer loop=$custid}
<p>
  id: {$custid[customer]}<br />
  name: {$name[customer]}<br />
  address: {$address[customer]}
</p>
{/section}

  

上述范例会输出

<p>
  id: 1000<br />
  name: John Smith<br />
  address: 253 Abbey road
</p>
<p>
  id: 1001<br />
  name: Jack Jones<br />
  address: 417 Mulberry ln
</p>
<p>
  id: 1002<br />
  name: Jane Munson<br />
  address: 5605 apple st
</p>

  

{section} 可以嵌套任意深度。利用嵌套 {section}，您可以访问复杂的数据结构，例如多维数组。这是一个分配数组的 .php 脚本示例。

<?php

$id = array(1001,1002,1003);
$smarty->assign('custid',$id);

$fullnames = array('John Smith','Jack Jones','Jane Munson');
$smarty->assign('name',$fullnames);

$addr = array('253 N 45th', '417 Mulberry ln', '5605 apple st');
$smarty->assign('address',$addr);

$types = array(
           array( 'home phone', 'cell phone', 'e-mail'),
           array( 'home phone', 'web'),
           array( 'cell phone')
         );
$smarty->assign('contact_type', $types);

$info = array(
           array('555-555-5555', '666-555-5555', '[email protected]'),
           array( '123-456-4', 'www.example.com'),
           array( '0457878')
        );
$smarty->assign('contact_info', $info);

?>
  

在此模板中，$contact_type[customer] 是当前客户的联系人类型数组。

{section name=customer loop=$custid}
<hr>
  id: {$custid[customer]}<br />
  name: {$name[customer]}<br />
  address: {$address[customer]}<br />
  {section name=contact loop=$contact_type[customer]}
    {$contact_type[customer][contact]}: {$contact_info[customer][contact]}<br />
  {/section}
{/section}

  

上述范例会输出

<hr>
  id: 1000<br />
  name: John Smith<br />
  address: 253 N 45th<br />
    home phone: 555-555-5555<br />
    cell phone: 666-555-5555<br />
    e-mail: [email protected]<br />
<hr>
  id: 1001<br />
  name: Jack Jones<br />
  address: 417 Mulberry ln<br />
    home phone: 123-456-4<br />
    web: www.example.com<br />
<hr>
  id: 1002<br />
  name: Jane Munson<br />
  address: 5605 apple st<br />
    cell phone: 0457878<br />

  

数据库搜索结果（例如 ADODB 或 PEAR）被分配给 Smarty

  
<?php
$sql = 'select id, name, home, cell, email from contacts '
      ."where name like '$foo%' ";
$smarty->assign('contacts', $db->getAll($sql));
?>

要以 HTML 表格输出数据库结果的模板

<table>
<tr><th>&nbsp;</th><th>Name></th><th>Home</th><th>Cell</th><th>Email</th></tr>
{section name=co loop=$contacts}
  <tr>
    <td><a href="view.php?id={$contacts[co].id}">view<a></td>
    <td>{$contacts[co].name}</td>
    <td>{$contacts[co].home}</td>
    <td>{$contacts[co].cell}</td>
    <td>{$contacts[co].email}</td>
  <tr>
{sectionelse}
  <tr><td colspan="5">No items found</td></tr>
{/section}
</table>
