smarty section 用法

参考了smarty的官方文档，不过是翻译了部分，也加了点注释，个人感觉是比较有用的。欢迎交流。

1、循环一个简单的一维数组：
Example 7-30. Looping a simple array with {section}

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

//customer和下面的foo可以随便命名，作用其实仅仅是一个index下标，用来引用数组中的元素
{section name=customer loop=$custid}    
  id: {$custid[customer]}

{/section}

---

{section name=foo loop=$custid step=-1}
  {$custid[foo]}

{/section}

//输出
id: 1000

id: 1001

id: 1002

---

id: 1002

id: 1001

id: 1000


2、不用assign数组直接在smarty中循环：
Example 7-31. {section} without an assigned array

//特别地设置了start,step属性用来控制循环
//$smarty.section.section的名字.index是一个特殊变量，用来显示当前循环的位置
{section name=foo start=10 loop=20 step=2}
  {$smarty.section.foo.index}
{/section}

---

{section name=bar loop=21 max=6 step=-2}
  {$smarty.section.bar.index}
{/section}

//输出：
10 12 14 16 18

---

20 18 16 14 12 10

3、section的name的值是随你定的
Example 7-32. Naming a {section}

{section name=anything loop=$myArray}
  {$myArray[anything].foo}
  {$name[anything]}     //这种用法目前还没怎么用过，也不太清楚
  {$address[anything].bar}    //这种也是
{/section}

4、遍历一个关联数组，嵌套的数组

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

//section不用嵌套，因为只有一个数组，数组内部用$contacts[customer]得到
//每个数组，再用.键名来得到键值
{section name=customer loop=$contacts}

  name: {$contacts[customer].name}

  home: {$contacts[customer].home}

  cell: {$contacts[customer].cell}

  e-mail: {$contacts[customer].email}

{/section}

The above example will output:

  name: John Smith

  home: 555-555-5555

  cell: 666-555-5555

  e-mail: [e-mail]

  name: Jack Jones

  home phone: [phone]

  cell phone: [phone]

  e-mail: [e-mail]

  name: Jane Munson

  home phone: [phone]

  cell phone: 123456

  e-mail: [e-mail]

5、从数据库查询记录显示，实际上是显示二维数组，其实同上例一样
$sql = 'select id, name, home, cell, email from contacts '
      ."where name like '$foo%' ";
$smarty->assign('contacts', $db->getAll($sql));
?>

//结果：



{section name=co loop=$contacts}     //第一维
 
      //第二维用.号来引用
   
   
   
   
 
{sectionelse}
 
{/section}

	Name>	Home	Cell	Email
view	{$contacts[co].name}	{$contacts[co].home}	{$contacts[co].cell}	{$contacts[co].email}
No items found

6、嵌套的section

$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', '[e-mail]'),
           array( '123-456-4', ''),
           array( '0457878')
        );
$smarty->assign('contact_info', $info);

?>

{section name=customer loop=$custid}

---

  id: {$custid[customer]}

  name: {$name[customer]}

  address: {$address[customer]}

  {section name=contact loop=$contact_type[customer]}
    {$contact_type[customer][contact]}: {$contact_info[customer][contact]}

  {/section}
{/section}

The above example will output:

---

  id: 1000

  name: John Smith

  address: 253 N 45th

    home phone: [phone]

    cell phone: [phone]

    e-mail: [e-mail]

---

  id: 1001

  name: Jack Jones

  address: 417 Mulberry ln

    home phone: [phone]

    web:

---

  id: 1002

  name: Jane Munson

  address: 5605 apple st

    cell phone: [phone]
