Inheritance 如何删除附加到父模板中块的内容？,inheritance,smarty,template-engine,Inheritance,Smarty,Template Engine,我有三个模板： base.tpl {block name="myBlock"} base {/block} {extends file="base.tpl"} {block name="myBlock" append} child {/block} {extends file="child.tpl"} {block name="myBlock" append} grandchild {/block} {block name="myBlock2"} base

我有三个模板：

base.tpl

{block name="myBlock"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock" append}
    grandchild
{/block}

{block name="myBlock2"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock2" append}
    grandchild
{/block}

{extends file="child.tpl"}
{block name="myBlock"}
    grandchild
{/block}
child.tpl

{block name="myBlock"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock" append}
    grandchild
{/block}

{block name="myBlock2"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock2" append}
    grandchild
{/block}

{extends file="child.tpl"}
{block name="myBlock"}
    grandchild
{/block}
孙子.第三方物流

{block name="myBlock"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock" append}
    grandchild

{block name="myBlock2"}
    base

    child

{block name="myBlock2" append}
    grandchild
{/block}

{extends file="child.tpl"}
{block name="myBlock"}
    grandchild
{/block}
渲染
孙子.tpl
时的输出为

base
child
grandchild
但是我想跳过
child.tpl
添加的内容，因此我想得到以下输出：

base
grandchild
问题是，这需要在不更改
base.tpl
和
child.tpl
（两者都来自第三方）的情况下完成，我不能只在
孙子.tpl
中扩展
base.tpl
，由于在
child.tpl
中有更多包含内容的块，我希望在结果中包含这些内容。

在这种情况下，您只需在
base.tpl
和
孙子.tpl
中更改块的名称，并保持
child.tpl
不变

base.tpl

{block name="myBlock"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock" append}
    grandchild
{/block}

{block name="myBlock2"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock2" append}
    grandchild
{/block}

{extends file="child.tpl"}
{block name="myBlock"}
    grandchild
{/block}
child.tpl

{block name="myBlock"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock" append}
    grandchild
{/block}

{block name="myBlock2"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child
{/block}

{extends file="child.tpl"}
{block name="myBlock2" append}
    grandchild
{/block}

{extends file="child.tpl"}
{block name="myBlock"}
    grandchild
{/block}
孙子.第三方物流

{block name="myBlock"}
    base
{/block}

{extends file="base.tpl"}
{block name="myBlock" append}
    child

{block name="myBlock" append}
    grandchild
{/block}

{block name="myBlock2"}
    base

{extends file="base.tpl"}
{block name="myBlock" append}
    child

{extends file="child.tpl"}
{block name="myBlock2" append}
    grandchild
{/block}

{extends file="child.tpl"}
{block name="myBlock"}
    grandchild
{/block}
现在的输出是：

基础
孙子

编辑-来自评论的信息之后，base.tpl也无法修改

似乎您唯一需要做的就是从
孙子.tpl
中删除
append
，并保留另外两个文件不变

正如你所希望的，我也不能修改
base.tpl
，它也来自第三方。。。抱歉，忘了提到这一点：（为什么这样做？我以为这样做会重置整个块，一直到继承树。但它似乎只是覆盖了
child.tpl
中的“append”？对我来说，这也很奇怪。但似乎当你不使用append（可能是prepend）时除了直接父项之外，此块的全部内容都已添加。您可以尝试在不添加附加的情况下再添加一个
grandgranter.tpl
，然后再次添加附加到granter。然后，输出将是
base child grandgranter
，以便使用除直接父项之外的父项内容。您还可以使用
{$smarty.block.parent}
并最终有输出，例如
基本子孙孙孙孙
