Concatenate is an action in the Kuika platform that allows you to combine two or more text (string) values to create a single text output. It is used in scenarios such as dynamic data merging, collecting user information in a single line, or creating text-based outputs.
Technical Features
Text Concatenation: Combines two different string values and returns a single string output.
Dynamic Data Support: Fixed values or dynamic parameters from the Symbol Picker can be combined.
Flexible Usage: Can be used with form fields, variables, API results, or user inputs.
Web and Mobile Application Compatibility: The Concatenate action works in both web and mobile applications.
Concatenate Action Application Steps
Log in to the Kuika platform.
Select the project you want to work on from the Apps screen.
Open the screen where you want to define the action in the UI Design module.
Open the Properties Panel on the right side.
Select the trigger event from the + ADD ACTION menu (e.g., Initial Actions, OnClick, OnBlur, etc.).
Add the StringOperations > Concatenate action from the menu that opens.
Configure the parameter fields as follows.
Action Parameters
Value1 (String - One): The first text value to be concatenated. This field can be defined as fixed (Fixed Value) or dynamic (Symbol Picker).
Value2 (String - One): The second text value to be concatenated. Like Value1, it supports fixed or dynamic data entry.
Don’t trigger validations (Boolean): When enabled, form validations are not triggered while the action is running.
Use “ ” (a space character) to leave a space when adding text with fixed values. For example, “Name: ” + UserName.
Usage Scenario: Concatenating First Name and Last Name
In a user form, the first name and last name fields are kept separately. At the end of the form, these two fields need to be displayed as a single string. The two values are combined using the Concatenate action.
Scenario Flow:
Values from the UserName and UserSurname fields are retrieved.
Value1: @UserName
Value2: “ ” + @UserSurname
Action result: Returns a single string, “John Doe”.
This way, user information can be used as a single line in reports, labels, or API calls.
Concatenate Action Advanced Customizations
Combining Multiple Values: Multiple strings can be combined by using the Concatenate action in a chained manner. For example: Name + “ ” + Surname + “ - ” + Department
Using Dynamic Placeholders: Dynamic text can be created by calling form or system variables with the Symbol Picker.
Data Formatting: Date, number, or status values can be combined with text to produce meaningful outputs (e.g., “Order Date: ” + @OrderDate).
Creating Notification Content: Emails or notification texts sent to users can be dynamically created using the Concatenate action.
Technical Risks
Empty Values: If Value1 or Value2 is empty, the result returns only the filled text. Therefore, checking for empty values is recommended.
Data Type Mismatch: Only works with string type values. If numerical or date type values are to be used, they must first be converted to string.
Missing Spaces: Values appear adjacent if manual spaces are not added during text concatenation.
Validation Disabled: When “Don't trigger validations” is enabled, form validations are skipped; this may lead to unexpected data flow.
