Kuika's Validation structure prevents incorrect entries by checking whether the data received from the user meets the specified conditions. This structure allows you to define both single conditions and logical groups consisting of multiple conditions (AND / OR). Validations work on an element basis and are managed through the Properties panel.
Validation Types and Examples
Fields that cannot be left blank: Allows users to fill in certain fields.
Error Message: “This field cannot be left blank.”
Format Controls: Checks for certain formats such as e-mail, phone number, etc.
Error Message: “Please enter a valid e-mail address.”
Character Count Control: Sets minimum and maximum character limits.
Error Message: “Your password must be at least 8 characters.”
Numeric Controls: Enables the entry of numbers within a certain range.
Error Message: “The age value must be between 18 and 60.”
Conditions Between Fields: Checks that two fields match each other.
Error Message: “Passwords do not match.”
Steps to Add Validation
Element Selection:
Select the data entry element from the UI Design module.
Open the Properties Panel:
Open the Properties panel on the right side.
Specify Validation Type:
Click the ADD VALIDATION button under the Properties panel. In the Validation field that opens, define the conditions under which the validation will be valid in the Will be valid if… section.
Select the relevant validation type (for example, Cannot be left blank or Format Check).
Define Conditions and Standards:
By default, an AND GROUP is created.
From the three-dot menu:
AND GROUP → OR GROUP conversion can be performed
Add Nested Group can be used to add nested conditions
Conditions can be added with the + button
When defining conditions, using the Symbol Picker:
Default values
The .value fields of the elements under Components can be selected.
Creating Error Messages:
Write the error message to be displayed to the user in the Invalid Message field.
Saving Validation:
Save the validation after completing all settings. If necessary, the Ignore If Not Visible option can be enabled to prevent validation from working when the element is not visible.
Advantages of Using Validation
Data Integrity: Prevents incorrect data entry.
User Experience: Guides users with error messages.
Flexibility: You can create custom validation rules.
Time and Cost Savings: Simplifies the resolution process by preventing errors early on.
By following these steps, you can add validation to your data entry elements on the Kuika platform, making your application more reliable and user-friendly.
