Fluidtemplates 的 Typoscript 条件

Question

我想用以下代码添加一个流体模板

[PIDupinRootline = 39] && [treeLevel = 4]
    lib.personSubMenuBack = FLUIDTEMPLATE
    lib.personSubMenuBack {
        file = EXT:sitepackage_my_domain/Resources/Private/TT_Address/Partials/PersonSubMenuBack.html
    }
[end]

在我添加的另一个流体模板中

<f:cObject typoscriptObjectPath="lib.personSubMenuBack" />

现在，当条件错误时，由于找不到“ lib.personSubMenuBack ”，我会收到页面错误。 为了避免这种情况，我在条件之前添加了这个

 lib.personSubMenuBack = FLUIDTEMPLATE
    lib.personSubMenuBack {
        file = EXT:sitepackage_my_domain/Resources/Private/TT_Address/Partials/PersonSubMenuEmpty.html

    }

我想知道是否有更优雅的方法来解决问题而无需额外的空流体PersonSubMenuEmpty

Answer 1

[PIDupinRootline = 39] && [treeLevel = 4]
    lib.personSubMenuBack = FLUIDTEMPLATE
    lib.personSubMenuBack {
        file = EXT:sitepackage_my_domain/....
    }
[else]
    lib.personSubMenuBack = TEXT
[end]
