Reflection Processor¶

TypoScript wrapper for Reflection Service. Maps data to a simple array structure, based on the TCA configuration of the table. Also resolves all TCA-relations to other tables. The strength lies in the fast loading of already existing structures, especially when using Ajax requests or headless systems.

Parameter	Description
buildingConfiguration	Contains e.g. instructions for the preparation of files and images (see Example Case).
debug	var_dumps information which elements would be reflected.
maxDepth	The maximum depth at which related elements are loaded (default is 8).
replace	Replace the current data with the result of this DataProcessor
row	If set, data content of row would be reflected, otherwise the current data would be used (default).
rows	Same behavior as using row, with one important difference: To guard against endless recursions and unperformant reloading of rows, the Reflection service uses an internal store for previously loaded elements. This is store is accessable for all elements in rows. This is a huge performance gain, especially when the elements in rows are often related to the same elements. Note Load order rows row current data
table	Tablename which should be mapped (default: tt_content) (see Example Case).
tableColumnBlacklist	List of table columns which should be blacklisted (wildcards like "*" and "?" are useable) (see Example Case). Note You don't need to blacklist core-related columns like 't3ver_oid', 't3_origuid', etc. The Reflection Service will filter them out. The 'uid' column can't be blacklisted
tableColumnRemapping	List of table columns to be renamed (see Example Case)
tableColumnRemoveablePrefixes	List of table columns where the prefix should be removed (see Example Case)
tableColumnWhitelist	List of table columns which should be whitelisted (wildcards like "*" and "?" are useable) (see Example Case)

Example Case¶

Assuming we have want to reflect of an slider element with the following table column / TCA structure:

CType "slider" (located in table tt_content)
- all default tt_content fields (header, categories, space_before_class, etc ...)
- tx_myextension_duration (input, with eval "int")
- tx_myextension_slides (IRRE relation to table tx_myextension_slides)
  - image (FAL with the croppings for desktop, medium, tablet, mobile)
  - headline (input)
  - descrition (RTE text)
  - link (input with link wizard)
  - categories (category tree)

Output before reflection¶

[
   'data' => [
      'uid' => 123,
      'pid' => 345,
      'categories' => 4,
      'header' => 'my slider',
      'tx_myextension_duration' => 8000,
      'tx_myextension_slides' = 3
      // ... many other system related columns
   ],
   'current' => null
]

Reflecting of related data¶

Attention

Don't reflect (tt_content) elements without black- or whitelisting! Every relation (including every sub-relation) would be resolved!

tt_content.slider.dataProcessing {
   10 = Jar\Utilities\DataProcessing\ReflectionProcessor
   10 {
      # FYI: this is superfluous, because "tt_content" is the default value
      table = tt_content

      tableColumnWhitelist {
         # just reflect the slide related fields and the header in tt_content
         tt_content = tx_myextension_*, header
      }

      tableColumnBlacklist {
         # don't reflect the "categories" column in tx_myextension_slides
         tx_myextension_slides = categories
      }

      tableColumnRemapping {
         tt_content {
            # rename the column "header" to "title" in the result
            header = title
         }
      }

      tableColumnRemoveablePrefixes {
         # remove the prefix "tx_myextension_" from our columns
         tt_content = tx_myextension_
      }

      buildingConfiguration {
         file {
            # we don't want deeper informations about files (f.e. filename, extension, size, etc ..)
            showDetailedInformations = 0

            # set image rendering instructions for the different cropping variants
            processingConfigurationForCrop {
               desktop.maxWidth = 3000
               medium.maxWidth = 1920
               tablet.maxWidth = 1024
               mobile.maxWidth = 920
            }
         }
      }
   }
}

Tip

In most cases buildingConfiguration it's helpful to outsource to an globaly place like an lib-object
