...
Forms – also referred to as Configurators
...
– is a structure that contains a set of input fields. You can create your own forms and include these in your logics.
...
This way it is easy to separate you pricing calculations from input generations, and to reuse
...
inputs across multiple logics.
Additionally, forms also
...
allow for a larger degree of freedom than inputs
...
generated in
...
the input generation mode. For example, you can have input fields appear, disappear, or change according to what other input the end
...
user provides.
...
To create a form, create a logic with default logic nature and return instances of ConfiguratorEntry and/or ConfiguratorEntryArray from its elements.
Including Forms in Other Logics
To include a form in your logic, build an input that references the form by its name:

❶ the processor can be one of the quoteProcessor, cProcessor, etc., which references subclasses of the CalculableLineItemCollectionBuilder |
You need to give each form an input name. The inputs from that form will be accessible via that name on the input binding variable:
| Code Block | ||
|---|---|---|
|
...
input.userInput.nameOfInput as ValueType |
Form Field Sets (ConfiguratorEntry)
A form field set (ConfiguratorEntry) is a container for inputs that
...
share the same purpose. A field set can be accompanied by a legend that describes the purpose of the field set.
...
| Info |
|---|
The configurator logic is executed each time the end |
...
user provides an input. This means that the input fields will be recreated on each execution. Therefore, to persist the value that the user just provided, you must explicitly set the value of the newly generated input field. |
| Code Block | ||
|---|---|---|
|
...
@Field String INPUT_FIRST_NAME = 'firstName'
@Field String INPUT_LAST_NAME = 'lastName'
ConfiguratorEntry getNameFieldSet(){
def firstNameInput = api.inputBuilderFactory() // ❶
.createStringUserEntry(INPUT_FIRST_NAME)
.setValue(input[INPUT_FIRST_NAME) // ❷
.setLabel('First Name')
.buildContextParameter()
def lastNameInput = api.inputBuilderFactory() // ❶
.createStringUserEntry(INPUT_LAST_NAME)
.seValue(input[INPUT_LAST_NAME]) // ❷
.setLabel('Last Name')
.buildContextParameter()
def nameFieldSet = api.createConfiguratorEntry()
nameFieldSet.inputs = [firstNameInput, lastNameInput]
nameFieldSet.message = 'Your Name'
return nameFieldSet
} |
❶ Create the two inputs that the form field set will contain.
❷ Set the value of the input field to the value that the user had already provided (if any).
...
Use as such
...
...
An element of a form logic (Configurator) that returns a form field set (ConfiguratorEntry)
...
| Code Block |
|---|
...
|
...
| |
return getNameFieldSet() |
Form Field Set Arrays (ConfiguratorEntryArray)
A field set array is a container for multiple form field sets.
...
Create a form field set array by providing the form field sets to api.createConfiguratorEntryArray():
| Code Block | ||
|---|---|---|
|
...
return api.createConfiguratorEntryArray(timeFieldSet, countryFieldSet) |
Where timeFieldSet and countryFieldSet are instances of ConfiguratorEntry:
| Code Block | ||
|---|---|---|
|
...
...
@Field String INPUT_YEAR = 'year'
@Field String INPUT_COUNTRY = 'country'
ConfiguratorEntry getTimeFieldSet(){
def fieldSet = api.createConfiguratorEntry()
fieldSet.message = 'Filter by Year'
fieldSet.inputs = [yearInput]
return fieldSet
}
ConfiguratorEntry getCountryFieldSet(){
def fieldSet = api.createConfiguratorEntry()
fieldSet.message = 'Filter by Country'
fieldSet.inputs = [countryInput]
return fieldSet
}
ContextParameter getYearInput(){
return api.inputBuilderFactory()
.createIntegerUserEntry(INPUT_YEAR)
.setLabel('Year')
.setValue(input[INPUT_YEAR])
.buildContextParameter()
}
ContextParameter getCountryInput(){
return api.inputBuilderFactory()
.createStringUserEntry(INPUT_COUNTRY)
.setLabel('Country Code')
.setValue(input[INPUT_COUNTRY])
.buildContextParameter()
} |
Interactive Forms
Forms can be made interactive,
...
meaning they can change appearance according to
...
the input provided by the end
...
user
...
.
In the example below, the country input is not made visible until the end
...
user
...
chooses a region first. If the user changes the region, the country input is cleared.
...
Example Configuration Inputs Groovy.
| Code Block | ||
|---|---|---|
|
...
return getCountryFieldSet()
@Field String INPUT_REGION = 'region'
@Field String INPUT_COUNTRY = 'country'
ConfiguratorEntry getCountryFieldSet(){
def fieldSet = api.createConfiguratorEntry()
fieldSet.message = 'Filter by Country'
fieldSet.inputs = regionValue ? [regionInput, countryInput] : [regionInput]
return fieldSet
}
// Methods for creating inputs
ContextParameter getRegionInput() {
// Lib
def regionLib = libs.Library_Geography.Region
def allRegions = regionLib.findAllRegions()
return api.inputBuilderFactory().createOptionEntry(INPUT_REGION)
.setOptions(allRegions)
.setValue(regionValue)
.buildContextParameter()
}
ContextParameter getCountryInput() {
// Lib
def countryLib = libs.Library_Geography.Country
def countryInfo = countryLib.findCountriesByRegion(regionValue)
Map<String, String> countryCode2CountryName = countryInfo.collectEntries { row ->
[(row[countryLib.FIELD_COUNTRY_CODE]): row[countryLib.FIELD_COUNTRY_NAME]]
}
def values = countryCode2CountryName.keySet().toList()
def value2Label = countryCode2CountryName
// If the user changed the region, reset the value
def isCountryInRegion = countryLib.isCountryInRegion(countryValue, regionValue)
def newCountry = isCountryInRegion ? countryValue : null
return api.inputBuilderFactory().createOptionEntry(INPUT_COUNTRY)
.setOptions(values)
.setLabels(value2Label)
.setValue(newCountry)
.buildContextParameter()
}
// Methods for reading user input values
String getRegionValue() {
return input[INPUT_REGION] as String
}
String getCountryValue() {
return input[INPUT_COUNTRY] as String
} |
Form Dialogs
A form can either be embedded, or it can be made to appear in a dialog. To open the dialog, the user will have to click
...
a button.
...
| Code Block | ||
|---|---|---|
|
...
api.inputBuilderFactory()
.createConfiguratorInputBuilder(
'Filters',
configuratorLogicName,
false // ❶
)
.getInput() |
❶ Open the form as a dialog, rather than embedding it.
Styles Legends
Legends can be styled, by providing the message as an HTML string with inline styling:
| Warning |
|---|
Be very restrained with inline |
...
styling, as this may clash with the frontend application’s style sheets. Even if it looks good at the moment, the frontend |
...
application styling might change in the future. |
| Code Block | ||
|---|---|---|
|
...
...
def nameFieldSet = api.createConfiguratorEntry()
nameFieldSet.inputs = [myInput]
nameFieldSet.message = '<code style="font-weight: bold;">Your Name</code>' // ❶ |
❶ The legend is wrapped within a code element and styled with bold.
Images
By setting the legend to
...
an HTML img element, you can display an image inside a form:
...
...
Example Configuration Image Groovy
| Code Block | ||
|---|---|---|
|
...
ConfiguratorEntry imageFieldSet(String sku, String alt){
def imageFieldSet = api.createConfiguratorEntry()
// Add a dummy input, or the backend will throw an |
...
exception def dummyInput = api.inputBuilderFactory().createHiddenEntry(sku).buildContextParameter() imageFieldSet.inputs = [dummyInput] String partition = api.currentPartitionName() def productImageUrl = "/pricefx/${partition}/productimages.get/${sku}?predefinedSize=enlarged_thumbnail" imageFieldSet.message = """<img src="$productImageUrl" alt="$alt"/>""" return imageFieldSet } |
