TYPO3 Text Media Element should get class from selected sys category - class

Question

I want to reach the following:
I'm creating an new content element "text media", fill out title, text and perhaps select an image. I also created categories which I select under the tab "categories".
Now I want to integrate these selected categories in the fluid template to make it work as an javascript filter.
How can I achieve this task?
Thanks!

You can use a DataProcessor to get the category data. You need to extend the TypoScript for the textmedia element.
Category example: https://git.spooner.io/spooner/just_news/blob/master/Configuration/TypoScript/RenderingDefinitions/news_list.ts#L23
DataProcessor documentation: https://docs.typo3.org/typo3cms/TyposcriptReference/ContentObjects/Fluidtemplate/Index.html#dataprocessing
Here you can see the default textmedia TS, added object 30:
# Text & Media:
# Any number of media wrapped right around a regular text element.
#
# CType: textmedia
tt_content.textmedia =< lib.contentElement
tt_content.textmedia {
templateName = Textmedia
dataProcessing {
10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
10 {
references.fieldName = assets
}
20 = TYPO3\CMS\Frontend\DataProcessing\GalleryProcessor
20 {
maxGalleryWidth = {$styles.content.textmedia.maxW}
maxGalleryWidthInText = {$styles.content.textmedia.maxWInText}
columnSpacing = {$styles.content.textmedia.columnSpacing}
borderWidth = {$styles.content.textmedia.borderWidth}
borderPadding = {$styles.content.textmedia.borderPadding}
}
# Get categories
30 = TYPO3\CMS\Frontend\DataProcession\DatabaseQueryProcessor
30 {
put the login in...
}
}
stdWrap {
editIcons = tt_content: header [header_layout], bodytext, assets [imageorient|imagewidth|imageheight], [imagecols|imageborder], image_zoom
editIcons {
iconTitle.data = LLL:EXT:fluid_styled_content/Resources/Private/Language/FrontendEditing.xlf:editIcon.textmedia
}
}
