TYPO3 FLUID two condition in one foreach?

Question

I have in a for each two condition. How can I clear the content? Don't need two content:

<f:for each="{newsItem.categories}" as="category">
    <f:if condition="{category.uid} == 2">
        <f:if condition="{newsItem.logo}">
            Logo 1
        </f:if>
    </f:if>
    <f:if condition="{category.uid} == 3">
        <f:if condition="{newsItem.logo}">
            Logo 1
        </f:if>
    </f:if>
</f:for>

I need one condition for 2 if´s In PHP I take a break? Thanks

Answer 1

You could use the ViewHelpers v:iterator.intersect and v:iterator.extract from the extension vhs . It's not really elegant:

<f:if condition="{newsItem.categories -> v:iterator.extract(key: 'uid') -> iterator.intersect(b: '{0: 2, 1: 3}')}">
    <f:if condition="{newsItem.logo}">
        Logo 1
    </f:if>
</f:if>

Alternatively, you could just write your own ViewHelper, which would be only a few lines of code.

You could also use the vhs if stack Viewhelper:

<v:if stack="{0: '{category.uid}', 1: '==', 2: '2', 3: 'OR', 4: '{category.uid}', 5: '==', 6: '3'}">
    <f:then>
        <f:if condition="{newsItem.logo}">
            Logo 1
        </f:if>
    </f:then>
</v:if>

If you just want to avoid 2 similar blocks of HTML then you could use f:render and f:section:

<f:for each="{newsItem.categories}" as="category">
<f:if condition="{category.uid} == 2">
    <f:render section="logo" arguments="{newsItem:newsItem}" />
</f:if>
<f:if condition="{category.uid} == 3">
    <f:render section="logo" arguments="{newsItem:newsItem}" />
</f:if>
</f:for>

<f:section name="logo">
    <f:if condition="{newsItem.logo}">
            Logo 1
    </f:if>
</f:section>
