For details see section of Template Interitance. * The {extends} tag must be on the first line of the template. * If a child template extends a parent template with the {extends} tag it may contain only {block} tags. Any other template content is ignored. * Use the syntax for template resources to extend files outside of the $template_dir directory. {extends}标签用在模板继承中子模版对父模板的继承。具体的细节参考[模板继承](#)一节。 {extends}标签用在模版中的第一行； 如果子模板用{extends}标签继承父模板，那么它只能包含{block}标签（内容），其它任何模板内容都将忽略； 使用此语法为模板资源继承$template_dir目录外的文件。 **Attribute： ** | Attribute Name | Type | Required | Default | Description | |-----|-----|-----|-----|-----| | file | string | yes | *n/a* | The name of the template file which is extended | **属性： ** | 属性名 | 类型 | 是否必须 | 缺省值 | 描述 | |-----|-----|-----|-----|-----| | file | string | yes | *n/a* | 需继承的模板名 | <table width="100%" border="0" cellpadding="0" cellspacing="0" class="EXAMPLE"><tr><td><div class="EXAMPLE"> <a name="AEN726" id="AEN726"> </a> <b><span class="PROGRAMLISTING">Example 7.26.
