{section}不能用于循环关联数组,它仅能循环数字索引的、连续下标的 (0,1,2,...)数组。
要循环关联数组,请使用
可选标记:
Example 7.63. 简单的{section}例子
<?php $data = array(1000,1001,1002); $smarty->assign('custid',$data); ?> 模板将输出该数组 {* 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} 输出: id: 1000<br /> id: 1001<br /> id: 1002<br /> <hr /> id: 1002<br /> id: 1001<br /> id: 1000<br /> Example 7.64. {section}不使用赋值数组 {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} 输出: 10 12 14 16 18 <hr /> 20 18 16 14 12 10 Example 7.65. 给{section}设置名称
{section name=anything loop=$myArray} {$myArray[anything].foo} {$name[anything]} {$address[anything].bar} {/section} Example 7.66. {section}中使用关联数组 下面是使用 <?php $data = array( array('name' => 'John Smith', 'home' => '555-555-5555', 'cell' => '666-555-5555', 'email' => 'john@myexample.com'), array('name' => 'Jack Jones', 'home' => '777-555-5555', 'cell' => '888-555-5555', 'email' => 'jack@myexample.com'), array('name' => 'Jane Munson', 'home' => '000-555-5555', 'cell' => '123456', 'email' => 'jane@myexample.com') ); $smarty->assign('contacts',$data); ?> 该模板用于显示 {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} 输出: <p> name: John Smith<br /> home: 555-555-5555<br /> cell: 666-555-5555<br /> e-mail: john@myexample.com </p> <p> name: Jack Jones<br /> home phone: 777-555-5555<br /> cell phone: 888-555-5555<br /> e-mail: jack@myexample.com </p> <p> name: Jane Munson<br /> home phone: 000-555-5555<br /> cell phone: 123456<br /> e-mail: jane@myexample.com </p> Example 7.67. {section}的 例子假定 <?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); ?>
{section name=customer loop=$custid} <p> id: {$custid[customer]}<br /> name: {$name[customer]}<br /> address: {$address[customer]} </p> {/section} 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> Example 7.68. {section}嵌套
{section}可以嵌套任意的深度。通过嵌套{section}你可以处理多维数组。
下面是例子的 <?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', 'john@myexample.com'), array( '123-456-4', 'www.example.com'), array( '0457878') ); $smarty->assign('contact_info', $info); ?> 在这个模板里, $contact_type[customer]是客户联系信息的数组 {section name=customer loop=$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} 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: john@myexample.com<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 /> Example 7.69. {sectionelse}的数据库例子 数据库查找的结果(如 ADODB 或 PEAR) 传递到 Smarty <?php $sql = 'select id, name, home, cell, email from contacts ' ."where name like '$foo%' "; $smarty->assign('contacts', $db->getAll($sql)); ?> 模板将以表格形式显示数据结果 <table> <tr><th> </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>
说明
如果 Example 7.70. {section}
说明
{section name=customer loop=$custid} {$smarty.section.customer.index} id: {$custid[customer]}<br /> {/section} 输出: 0 id: 1000<br /> 1 id: 1001<br /> 2 id: 1002<br />
Example 7.71. <?php $data = array(1001,1002,1003,1004,1005); $smarty->assign('rows',$data); ?> 在表格中显示数组 {* $rows[row.index] and $rows[row] are identical in meaning *} <table> <tr> <th>index</th><th>id</th> <th>index_prev</th><th>prev_id</th> <th>index_next</th><th>next_id</th> </tr> {section name=row loop=$rows} <tr> <td>{$smarty.section.row.index}</td><td>{$rows[row]}</td> <td>{$smarty.section.row.index_prev}</td><td>{$rows[row.index_prev]}</td> <td>{$smarty.section.row.index_next}</td><td>{$rows[row.index_next]}</td> </tr> {/section} </table> 输出: index id index_prev prev_id index_next next_id 0 1001 -1 1 1002 1 1002 0 1001 2 1003 2 1003 1 1002 3 1004 3 1004 2 1003 4 1005 4 1005 3 1004 5
Note
它和 Example 7.72. <?php // array of 3000 to 3015 $id = range(3000,3015); $smarty->assign('arr',$id); ?> 模板将按 {section name=cu loop=$arr start=5 step=2} iteration={$smarty.section.cu.iteration} index={$smarty.section.cu.index} id={$custid[cu]}<br /> {/section} 输出: iteration=1 index=5 id=3005<br /> iteration=2 index=7 id=3007<br /> iteration=3 index=9 id=3009<br /> iteration=4 index=11 id=3011<br /> iteration=5 index=13 id=3013<br /> iteration=6 index=15 id=3015<br />
这里是另一个例子,使用 <table> {section name=co loop=$contacts} {if $smarty.section.co.iteration is div by 5} <tr><th> </th><th>Name></th><th>Home</th><th>Cell</th><th>Email</th></tr> {/if} <tr> <td><a href="view.php?id={$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> {/section} </table>
一个用 <table> {section name=co loop=$contacts} {if $smarty.section.co.iteration is even by 3} <span style="color: #ffffff">{$contacts[co].name}</span> {else} <span style="color: #dddddd">{$contacts[co].name}</span> {/if} {/section} </table> Note
"is div by"语法是PHP取模运算的一个变种。取模运算 Note你还可以用"is odd by"来反转交替。
如果当前的循环是最后一次,那么 Example 7.73. {section} 属性
例子循环了 {section name=customer loop=$customers} {if $smarty.section.customer.first} <table> <tr><th>id</th><th>customer</th></tr> {/if} <tr> <td>{$customers[customer].id}}</td> <td>{$customers[customer].name}</td> </tr> {if $smarty.section.customer.last} <tr><td></td><td>{$smarty.section.customer.total} customers</td></tr> </table> {/if} {/section}
Example 7.74. {section} 属性 {section name=customer loop=$custid} {$smarty.section.customer.index} id: {$custid[customer]}<br /> {/section} There are {$smarty.section.customer.loop} customers shown above. 输出: 0 id: 1000<br /> 1 id: 1001<br /> 2 id: 1002<br /> There are 3 customers shown above.
Example 7.75. 布尔值 {section name=customer loop=$customers show=$show_customer_info} {$smarty.section.customer.rownum} id: {$customers[customer]}<br /> {/section} {if $smarty.section.customer.show} the section was shown. {else} the section was not shown. {/if} 输出: 1 id: 1000<br /> 2 id: 1001<br /> 3 id: 1002<br /> the section was shown.
Example 7.76. {section name=customer loop=$custid step=2} {$smarty.section.customer.index} id: {$custid[customer]}<br /> {/section} There are {$smarty.section.customer.total} customers shown above.
