i18n样例 i18n:translate：翻译(1):

<span i18n:domain="plone" i18n:translate="">title</span>

i18n:attributes 翻译属性:

METAL样例 macros的定义和使用:

<span metal:define-macro="abc"> 
<table border="2">
 <tr>
<td>aaa</td>
<td>aaa</td>
</tr> 
<tr>
<td>aaa</td>
<td>aaa</td>
</tr>
 </table>
</span>
<div metal:use-macro="template/macros/abc"/>google广告宏:
<tal:block tal:condition="nothing">
 <div metal:define-macro="portlet">
 <div class="portlet">
 <script type="text/javascript">
<!– google_ad_client = "yourUniqueValue";
 google_ad_width = 120;
 google_ad_height = 600;
 google_ad_format = "120x600_as"; //–>
</script>
 <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"/>
 </div>
 </div>
</tal:block>
<div metal:use-macro="template/macros/portlet"/>slot的定义和使用:
<div metal:define-macro="macro-a">
 <span>start text in macro-a</span>
 <div metal:define-slot="slot-b"> default text in slot-b </div>
 <span>end text in macro-a</span>
</div>
<div metal:use-macro="template/macros/macro-a"> can this line visible? </div>
<div metal:use-macro="template/macros/macro-a"> 
<div metal:fill-slot="slot-b"> can this line visible in slot-b? </div>
</div>
分析Plone的主模板的宏:
<span tal:replace="python:context.main_template.macros.keys()"/>
访问archetypes中的field显示Field的一个widget:
<metal:block use-macro="here/global_defines/macros/defines" />
 <div tal:define="errors python:{}; ">
 <input metal:use-macro="python: here.Members.widget('title', mode='edit')"
  name="textfield"
  type="text" size="30"/>
 </div>
访问field的值:
<div tal:omit-tag="" tal:define="field python:here.Members.Schema()['title'];
                                 accessor python:getattr(here.Members, field.accessor)" 
     tal:content="python:accessor()"> </div>
访问事件的类型字段（字典）(context应该是事件):
<div tal:define="field python:here.testeventvoc.Schema()['eventType'];
                 accessor python:getattr(here.testeventvoc, field.accessor);
                 vocab python:field.Vocabulary(here.testeventvoc)">
 <span tal:repeat="value accessor" tal:content="python:vocab.getValue(value)"/>
</div>

TAL语法测试

<html>
 <head>
 <title tal:content="template/title">The title</title>
 </head>
 <body>
 <h2><span tal:replace="here/title_or_id">content title or id</span>
     <span tal:define="global title python:getattr(template, 'ti tle')"
           tal:on-error="string:"
           tal:condition="title"
           tal:replace="template/title">optional title</span>
</h2>
 This is Page Template <em tal:content="template/id">template id</em>.
 <h2 tal:omit-tag="">request</h2>
 <p tal:content="structure request"> request </p>
 <p tal:repeat="i python: range(10)">
    <input value="2" tal:condition="python: i > 5 "
                     tal:attributes="value python: i+100; style string:color: red;"/>
 </p>
 </body>
</html>

列举网站根下的所有内容

<html>
<head>
   <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
    <title tal:content="template/title">The title</title>
 </head>
 <body>
 <h2><span tal:replace="here/title_or_id">content title or id</span>
     <span tal:condition="template/title" tal:replace="template/title">optional template title</span>
 </h2>
 <div tal:define="portal context/portal_url/getPortalObject">
   <p tal:repeat="content portal/listFolderContents" 
      tal:content="string:${repeat/content/number}: ${content/Title}(${content/id})">
   </p>
 </div>
 </body>
</html>

ZPT调用ScriptScript得到网站会员清单(id: getSiteMembers):
membership = context.portal_membershipmembers = []
# 打印姓名和邮件

for m in membership.listMembers():
  members.append({'id':m.getId(), 
                  'fullname':m.getProperty('fullname'),
                  'email':m.getProperty('email'),
                  'roles':m.getRoles() })
    return members

表格方式列举网站所有的成员信息:

<html>
 <head>
 <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
 <title tal:content="template/title">The title</title>
 </head>
 <body>
 <h2><span tal:replace="here/title_or_id">content title or id</span>
     <span tal:condition="template/title" tal:replace="template/title">optional template title</span>
 </h2>
 <table border="1">
 <tr> <th>登录名</th> <th>姓名</th> <th>电子邮件</th> <th>角色</th> </tr>
 <tr tal:repeat="member context/getSiteMembers">
   <td tal:content="member/id"/>
   <td tal:content="member/fullname"/>
   <td>
    <a tal:content="member/email"
       tal:attributes="href string:mailto:${member/email};
       title member/fullname">[email]aa@bb.com[/email]</a>
   </td>
   <td><span tal:content="python: ','.join(member['roles'])"/>
       <span tal:condition="python:'Manager' in member['roles']">※※※</span>
   </td>
  </tr>
 </table>
 </body>
</html>
Script中调用ZPT脚本:
return context.CalledZPT(1,2,a=3,b=4)ZPT（id: CalledZPT）:
<html>
 <head>
 <title tal:content="template/title">The title</title>
 </head>
 <body>
 <h1>这个页面是Script(Python)调用的ZPT生成的</h1>
 <span>传递的参数保存在options绑定变量中：</span>
 <span tal:replace="options"/>
 </body>
</html>

搜索显示网站所有的文件夹

<html>
 <head>
 <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
 <title tal:content="template/title">The title</title>
 </head>
 <body>
 <h2><span tal:replace="here/title_or_id">content title or id</span>
     <span tal:condition="template/title" tal:replace="template/title">optional template title</span>
 </h2> <ol tal:define="folders python:here.portal_catalog.searchResults(portal_type='Folder')">
         <li tal:repeat="content folders" tal:content="string:${content/Title}(${content/getPath})">
         </li>
       </ol>
 </body>
</html>

定义一个Google广告宏macro_GoogleAD:

<div metal:define-macro="portlet">
 <h3 metal:define-slot="title"> 广告 </h3>
 <script type="text/javascript">
<!– google_ad_client = "yourUniqueValue";
 google_ad_width = 120;
 google_ad_height = 600;
 google_ad_format = "120x600_as"; //–>
</script>
 <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"/>
</div>

使用宏:

<div metal:use-macro="context/macro_GoogleAD/macros/portlet" />
