For details see section of Template Interitance. The {block} template source area of a child template will replace the correponding areas in the parent template(s). Optionally {block} areas of child and parent templates can be merged into each other. You can append or prepend the parent {block} content by using the append or prepend option flag with the childs {block} definition. With the {$smarty.block.parent} the {block} content of the parent template can be inserted at any location of the child {block} content. {$smarty.block.child} inserts the {block} content of the child template at any location of the parent {block}. {blocks}'s can be nested. {block}用来定义一个命名的模板继承源区域。具体细节可参考[模板继承](#)章节。 {block}的一个子模板源区将取代父模板中的相应区域。任意的子、父模板{block}区域可以彼此结合。可以利用子{block}定义中的*append*、*prepend*选项标记追加或预置父{block}内容。使用{$smarty.block.parent}可将父模板的{block}内容插入至子{block}内容中的任何位置。使用{$smarty.block.child}可将子模板{block}内容插入至父{block}内容中的任何位置。 {block}可以嵌套。 **Attribute： ** | Attribute Name | Type | Required | Default | Description | |-----|-----|-----|-----|-----| | name | string | yes | *n/a* | The name of the template source block | **option flags(in children template only):** | **Name** | **Description** | |-----|-----| | append | The {block} content will be be appended to the content of the parent template {block} | | prepend | The {block} content will be prepended to the content of the parent template {block} | | nocache | Disables caching of the {block} content | **属性： ** | 属性名 | 类型 | 是否必须 | 缺省值 | 描述 | |-----|-----|-----|-----|-----| | name | string | yes | *n/a* | 模板源块名称 | **选项标签（只对子模版有效）：** | **名称** | **描述** | |-----|-----| | append | {block}内容将追加到父模板{block}内容中 | | prepend | {block}内容将添加到父模板{block}内容中 | | nocache | 用'nocache' 属性为变量赋值 | 译注 | append与prepend作用方向是相反的，append是添加到父模板后面，而prepend是添加到父模板前面。 | |-----| <table width="100%" border="0" cellpadding="0" cellspacing="0" class="EXAMPLE"><tr><td><div class="EXAMPLE"> <a name="AEN2715" id="AEN2715"> </a> Example 7.15.
