如何使用Fluid和tx-news中的图像源填充Flexsliders data-thumb属性？

Question

我正在实现一个基于TYPO3扩展“news”和Flexslider的新闻滑块。新闻滑块包含缩略图预览图像，这些图像通过“data-thumb”属性加载，该属性包含滑块中每个图像的URL。如何获取Fluid中的URL和新闻扩展？

我尝试了以下但我收到一个错误：

<li data-thumb="{f:uri.image(image:mediaElement,title:'{mediaElement.originalResource.title}',alt:'{mediaElement.originalResource.alternative}', maxWidth:'{settings.list.media.image.maxWidth}',maxHeight:'{settings.list.media.image.maxHeight}')}">...</li>

滑块中一个对象的完整部分如下所示：

<li class="item itemtype-{newsItem.type}{f:if(condition: newsItem.istopnews, then: ' topnews')}" data-thumb="{f:uri.image(image:mediaElement,title:'{mediaElement.originalResource.title}',alt:'{mediaElement.originalResource.alternative}', maxWidth:'{settings.list.media.image.maxWidth}',maxHeight:'{settings.list.media.image.maxHeight}')}" itemscope="itemscope" itemtype="http://schema.org/Article">

    <n:excludeDisplayedNews newsItem="{newsItem}"/>
    <f:if condition="{newsItem.mediaPreviews}">
        <!-- media preview element -->
        <f:then>
            <div>
                <n:link newsItem="{newsItem}" settings="{settings}" title="{newsItem.title}">
                    <f:alias map="{mediaElement: '{newsItem.mediaPreviews.0}'}">
                        <f:if condition="{mediaElement.originalResource.type} == 2">
                            <f:image image="{mediaElement}" title="{mediaElement.originalResource.title}" alt="{mediaElement.originalResource.alternative}" width="{f:if(condition: settings.media.maxWidth, then: settings.media.maxWidth, else: settings.list.media.image.maxWidth)}" height="{f:if(condition: settings.media.maxHeight, then: settings.media.maxHeight, else: settings.list.media.image.maxHeight)}"/>
                        </f:if>
                        <f:if condition="{mediaElement.originalResource.type} == 4">
                            <f:render partial="Detail/MediaVideo" arguments="{mediaElement: mediaElement}"/>
                        </f:if>
                        <f:if condition="{mediaElement.originalResource.type} == 5">
                            <f:image image="{mediaElement}" title="{mediaElement.originalResource.title}" alt="{mediaElement.originalResource.alternative}" width="{f:if(condition: settings.media.maxWidth, then: settings.media.maxWidth, else: settings.list.media.image.maxWidth)}" height="{f:if(condition: settings.media.maxHeight, then: settings.media.maxHeight, else: settings.list.media.image.maxHeight)}"/>
                        </f:if>
                    </f:alias>
                </n:link>
            </div>
        </f:then>
        <f:else>
            <f:if condition="{settings.displayDummyIfNoMedia}">
                <div>
                    <span class="no-media-element">
                        <n:link newsItem="{newsItem}" settings="{settings}" title="{newsItem.title}">
                            <f:image src="{settings.list.media.dummyImage}" title="" alt="" width="{f:if(condition: settings.media.maxWidth, then: settings.media.maxWidth, else: settings.list.media.image.maxWidth)}" height="{f:if(condition: settings.media.maxHeight, then: settings.media.maxHeight, else: settings.list.media.image.maxHeight)}"/>
                        </n:link>
                    </span>
                </div>
            </f:if>
        </f:else>
    </f:if> 
    <div class="flex-caption">
        <h1 class="fvl flex-title">
            <n:link newsItem="{newsItem}" settings="{settings}" title="{newsItem.title}">
                <span itemprop="headline">{newsItem.title -> f:format.crop(maxCharacters: '40', respectWordBoundaries:'1')}</span>
            </n:link>
        </h1>
        <p class="flexslider-subtitle">
            <n:removeMediaTags>
            <f:if condition="{newsItem.teaser}">
                <f:then>
                    <span itemprop="description">{newsItem.teaser -> f:format.crop(maxCharacters: '{settings.cropMaxCharacters}', respectWordBoundaries:'1') -> f:format.stripTags()}</span>
                </f:then>
                <f:else>    
                    <span itemprop="description"></div>{newsItem.bodytext -> f:format.crop(maxCharacters: '{settings.cropMaxCharacters}', respectWordBoundaries:'1') -> f:format.stripTags()}</span>
                </f:else>
            </f:if>
            </n:removeMediaTags>
            <span>
                <n:link newsItem="{newsItem}" settings="{settings}" class="more" title="{newsItem.title}">
                    <f:translate key="more-link"/>
                </n:link>
            </span>
        </p>
    </div>
</li>

什么提示我做错了什么？我知道还有新闻滑块扩展，但我不希望进一步依赖另一个扩展。

看起来括号设置错误，您必须“逃离”开始和结束括号。

试试这个：

<li data-thumb="<f:format.raw>{</f:format.raw>
    {f:uri.image(image:mediaElement)},
    title:'{mediaElement.originalResource.title}',
    alt:'{mediaElement.originalResource.alternative}', 
    maxWidth:'{settings.list.media.image.maxWidth}',
    maxHeight:'{settings.list.media.image.maxHeight}'
<f:format.raw>}</f:format.raw>">...</li>

---

更新：

这是你的全部。你必须使用{newsItem.mediaPreviews.0}：

<li class="item itemtype-{newsItem.type}{f:if(condition: newsItem.istopnews, then: ' topnews')}" data-thumb="<f:format.raw>{</f:format.raw>{f:uri.image(image:newsItem.mediaPreviews.0)},title:'{newsItem.mediaPreviews.0.originalResource.title}',alt:'{newsItem.mediaPreviews.0.originalResource.alternative}',maxWidth:'{settings.list.media.image.maxWidth}',maxHeight:'{settings.list.media.image.maxHeight}'<f:format.raw>}</f:format.raw>" itemscope="itemscope" itemtype="http://schema.org/Article">

    <n:excludeDisplayedNews newsItem="{newsItem}"/>
    <f:if condition="{newsItem.mediaPreviews}">
        <!-- media preview element -->
        <f:then>
            <div>
                <n:link newsItem="{newsItem}" settings="{settings}" title="{newsItem.title}">
                    <f:alias map="{mediaElement: '{newsItem.mediaPreviews.0}'}">
                        <f:if condition="{mediaElement.originalResource.type} == 2">
                            <f:image image="{mediaElement}" title="{mediaElement.originalResource.title}" alt="{mediaElement.originalResource.alternative}" width="{f:if(condition: settings.media.maxWidth, then: settings.media.maxWidth, else: settings.list.media.image.maxWidth)}" height="{f:if(condition: settings.media.maxHeight, then: settings.media.maxHeight, else: settings.list.media.image.maxHeight)}"/>
