Getting parent / nested Flux CE within fluid

Question

Is it possible to get the parent CE type/name within a nested CE? I have a Custom Flux Grid CE with two columns, inside the columns you can place another CE. Now I would like to detect if the child is inside the grid, if yes do this and that.

what construction or extension do you use to stack CEs into each other? you might add tags regarding extensions and versions. — Bernd Wilke πφ, Feb 18 '19 at 11:43

Regardless of the technology used to store the relation between parent and child, you could always go for the FLUIDTEMPLATE parameter dataProcessing.

Either create a variable children or parent via a DatabaseQueryProcessor like that

tt_content.mycontent.20 = FLUIDTEMPLATE
tt_content.mycontent.20 {
   file = EXT:site_default/Resources/Private/Templates/ContentObjects/MyContent.html

   dataProcessing.10 = TYPO3\CMS\Frontend\DataProcessing\DatabaseQueryProcessor
   dataProcessing.10 {
      # regular if syntax
      if.isTrue.field = records

      # the table name from which the data is fetched from
      # + stdWrap
      table = tt_address

      # All properties from .select can be used directly
      # + stdWrap
      colPos = 1
      pidInList = 13,14

      # The target variable to be handed to the ContentObject again, can
      # be used in Fluid e.g. to iterate over the objects. defaults to
      # "records" when not defined
      # + stdWrap
      as = myrecords

      # The fetched records can also be processed by DataProcessors.
      # All configured processors are applied to every row of the result.
      dataProcessing {
         10 = TYPO3\CMS\Frontend\DataProcessing\FilesProcessor
         10 {
            references.fieldName = image
         }
      }
   }
}

You can use all the parameters of select for that DataProcessor and each of them can be modified using stdWrap properties. https://docs.typo3.org/typo3cms/TyposcriptReference/Functions/Select.html

Just make sure to replace as = myrecords with the desired variable name and then access this variable directly from within your Fluid template. You can use <f:debug>{_all}</f:debug> to get an overview of the available variables.

Taken from these docs https://docs.typo3.org/typo3cms/TyposcriptReference/ContentObjects/Fluidtemplate/Index.html#dataprocessing

Additionally you might want to take a look at this video https://www.twitch.tv/videos/380759921 to get an idea what dataProcessing is about.

Ok I think I missed a small detail, I use flux for my CEs. Don't know if your method (which I honestly didn't understood completly) works in this case. — Paul, Feb 18 '19 at 16:38
You could render Flux content with a FLUIDTEMPLATE cObject too, but in this case it might be easier to transfer variables directly, since the information is already available without using a data processor: https://stackoverflow.com/questions/24690804/how-the-get-the-parent-element-of-a-fce-in-fluid-powered-typo3 — Jo Hasenau, Feb 18 '19 at 20:15

Since the FLUIDTEMPLATE approach is a universal one, while the question might be closer related to Flux, here is a Flux specific way to hand over information to child records:

https://fluidtypo3.org/viewhelpers/flux/master/Content/RenderViewHelper.html

<flux:content.render 
    area="NULL"
    limit="123"
    offset="123"
    order="'sorting'"
    sortDirection="'ASC'"
    as="NULL"
    loadRegister="{foo: 'bar'}"
    render="1"
>
    <!-- tag content - may be ignored! -->
</flux:content.render>

Just fill in some additional information to the loadRegister named foo to make it available via the getText method register:foo within the child rendering process.

loadRegister="{parentRecordType: '2'}"

and within your child record rendering use

10 = TEXT
10.dataWrap = My parent record is of type {register:parentRecordType}

Same goes for if conditions or switch objects based on the registered information. And of course for Fluid based rendering of child records too.

Just use <f:debug>_all</f:debug> to get an overview of available registers and data.

Yes, everything is possible with TYPO3 and in a lot of ways. How are the content elements nested? From parent to children (templavoila) or from children to parent (gridelements)?

that's more a comment than an answer :( – Bernd Wilke πφ Feb 18 '19 at 11:41
Yes, sorry, should be a comment because feedback is needed to answer the question. – Alex Kellner Feb 18 '19 at 12:14
