HomeBackend DevelopmentPHP Tutorialsmarty中常用方法实例总结_PHP

本文实例总结了smarty中常用方法。分享给大家供大家参考。具体如下:

1. Smarty中foreach的index、iteration的使用

.index包含当前数组索引,从零开始。

index示例

{* The header block is output every five rows *}
{* 每五行输出一次头部区块 *}
<table>
{foreach from=$items key=myId item=i name=foo}
  {if $smarty.foreach.foo.index % 5 == 0}
   <tr><th>Title</th></tr>
  {/if}
  <tr><td>{$i.label}</td></tr>
{/foreach}
</table>

.iteration包含当前循环次数,与index不同,从1开始,每次循环增长1。

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}

2. smarty中section的嵌套使用

示例1:

$bookmarks = array('0' => array('name'=> 'n1', 'url'=>'url2'), '1' => array('name'=> 'n21', 'url'=>'url22'));
$categories= array('0' => array('cate_id'=> 'n1', 'cate_name'=>'url2'), '1' => array('cate_id'=> 'n21', 'cate_name'=>'url22'));
{section name='bm' loop=$bookmarks}
 Name:$bookmarks[bm].name
 URL:$bookmarks[bm].url
  {section name='cate' loop=$categories[bm]}
     $categories[bm][cate].cate_id
     $categories[bm][cate].cate_name
  {/section}
{/section}
::::

示例2:

$lists = array();
for(...){
  $oneList['dateTime'] = date("Y-m-d");
  $oneList['detailList'] = array();
  for(....){
    $oneList['detailList'][$j]['count'] = $onecout;
    $oneList['detailList'][$j]['title'] = $onetitle;
  }
  $lists[] = $oneList;
}
:::::
{section name=loop loop=$lists}
  {$lists[loop].dateTime}
  {section name=loop2 loop=$lists[loop]["detailList"]}
    {$lists[loop]['detailList'][loop2].title}
    {$lists[loop]["detailList"][loop2].count}
  {/section}
{/section}

3. 其他常用关键字

    name: section的名称,不用加$;
    $loop: 要循环的变量,程度中要使用assign对这个变量进行操作。
    $start: 开始循环的下标。默认为0;
    $step: 每次循环下标的增数;
    $show : boolean型。决定是否对于这块进行显示。默认为true;

的属性;

    index:循环下标。默认为0;
    index_prev:当前下标的上一个值,默认为-1;
    index_next:当前下标的下一个值,默认为1;
    first:是否为第一下循环;
    last:是否为最后一个循环;
    iteration:循环个数;
    rownum:当前行号,iteration的别名;
    loop:最后一个循环号。Section的循环次数;
    show:是否显示;

<{section loop=$News}>
   新闻编号:<{$News[loop].newID}><br>
   新闻内容:<{$News[loop].newTitle}><br>
<{sectionelse}>
   I am sorry
<{/section}>

if用法:

{if $list[row].name eq "1"}
  星期1
{elseif $list[row].name=="2"}
  星期2
{else}
  默认
{/if}

4. smarty 系统变量

{* 显示URL中的page值($_GET)http://www.example.com/index.php?page=foo *}
{$smarty.get.page}
{* 显示来自一个表单的"page"变量($_POST['page'])*}
{$smarty.post.page}
{* 显示COOKIE变量"username"的值($_COOKIE['username'])*}
{$smarty.cookies.username}
{* 显示服务器变量"SERVER_NAME"($_SERVER['SERVER_NAME'])*}
{$smarty.server.SERVER_NAME}
{$smarty.server.PHP_SELF}
{$smarty.server.SCRIPT_NAME}
{* 显示系统环境变量"PATH" *}
{$smarty.env.PATH}
{* 显示PHP会话变量"id"($_SESSION['id'])*}
{$smarty.session.id}
{* 显示变量"username",不论来自get/post/cookies/server/env *}
{$smarty.request.username}
$smarty}保留变量可以被用于访问一些特殊的模板变量,以下是全部页面请求变量。

以下是访问页面请求变量诸如get,post,cookies,server,enviroment和session变量的例子. 例如{$smarty.server.SERVER_NAME}取得服务器变量,{$smarty.env.PATH}取得系统环境变量path,{$smarty.request.username}取得get/post/cookies/server/env的复合变量。

{$smarty.now}变量用于访问当前时间戳.
可以用 date_format调节器格式化输出. 例如{$smarty.now|date_format:"%Y-%m-%d %H:%M:%S"}

{$smarty.const}
你可以直接访问PHP常量. 例如{$smarty.const._MY_CONST_VAL}

{$smarty.capture}
可以通过{capture}..{/capture}结构 截取的输出可以使用{$smarty} 变量访问.

{$smarty.config}
{$smarty}变量 可以访问已经加载的config变量.

例如 {$smarty.config.foo}就可以表示 {#foo#}.

{$smarty.section}, {$smarty.foreach}
{$smarty} 变量可以访问'section'和'foreach'循环的属性.
{$smarty.template}
显示当前被处理的模板的名字.
{$smarty.version}
显示smarty模板的版本
{$smarty.ldelim}
显示左分隔符
{$smarty.rdelim}

显示右分隔符$smarty}保留变量可以被用于访问一些特殊的模板变量,以下是全部页面请求变量。

What are some common problems that can cause PHP sessions to fail?What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

What are the advantages of using a database to store sessions?What are the advantages of using a database to store sessions?Apr 24, 2025 am 12:16 AM

The main advantages of using database storage sessions include persistence, scalability, and security. 1. Persistence: Even if the server restarts, the session data can remain unchanged. 2. Scalability: Applicable to distributed systems, ensuring that session data is synchronized between multiple servers. 3. Security: The database provides encrypted storage to protect sensitive information.

How do you implement custom session handling in PHP?How do you implement custom session handling in PHP?Apr 24, 2025 am 12:16 AM

Implementing custom session processing in PHP can be done by implementing the SessionHandlerInterface interface. The specific steps include: 1) Creating a class that implements SessionHandlerInterface, such as CustomSessionHandler; 2) Rewriting methods in the interface (such as open, close, read, write, destroy, gc) to define the life cycle and storage method of session data; 3) Register a custom session processor in a PHP script and start the session. This allows data to be stored in media such as MySQL and Redis to improve performance, security and scalability.

What is a session ID?What is a session ID?Apr 24, 2025 am 12:13 AM

SessionID is a mechanism used in web applications to track user session status. 1. It is a randomly generated string used to maintain user's identity information during multiple interactions between the user and the server. 2. The server generates and sends it to the client through cookies or URL parameters to help identify and associate these requests in multiple requests of the user. 3. Generation usually uses random algorithms to ensure uniqueness and unpredictability. 4. In actual development, in-memory databases such as Redis can be used to store session data to improve performance and security.

How do you handle sessions in a stateless environment (e.g., API)?How do you handle sessions in a stateless environment (e.g., API)?Apr 24, 2025 am 12:12 AM

Managing sessions in stateless environments such as APIs can be achieved by using JWT or cookies. 1. JWT is suitable for statelessness and scalability, but it is large in size when it comes to big data. 2.Cookies are more traditional and easy to implement, but they need to be configured with caution to ensure security.
