How to add a Regex condition to your input fields?
Regular expressions (regex) are powerful tools that allow you to define specific patterns for validating user input. In NoteForms, you can use regex to ensure that data entered into your form fields adheres to specific rules, improving data quality and consistency.
What is Regex?
Regex is a sequence of characters that defines a search pattern. It's used to match, locate, and manipulate text based on predefined rules. For example, you can use regex to:
Validate email addresses: Ensure they contain the "@" symbol and a valid domain.
Check phone numbers: Verify the correct number of digits and format.
Enforce password complexity: Require a minimum length, specific characters (letters, numbers, symbols).
Restrict input to specific characters: Allow only letters, numbers, or a combination.
How to Add Regex Validation in NoteForms
Go to the Field Settings: Open the settings for the specific field you want to validate.
Click on the Logic Tab: Navigate to the Logic tab to configure conditions for the field.
Add a Condition: Under the conditions section, select either Matches or Does not match Regex.
Enter your regex pattern: In the provided input box, enter the regex pattern that defines the acceptable input format.
Example of Regex Validation in NoteForms
Let's say you want to validate a "Name" field to ensure it only accepts letters and spaces:
Go to the Field Settings for the "Name" field.
Click on the Logic Tab.
Add a Condition: Select Matches Regex.
Enter the regex pattern: ^[a-zA-Z ]+$
With this setup, only inputs containing letters and spaces will be accepted in the "Name" field.
Tips for Using Regex in NoteForms
Test Your Pattern: Before implementing a regex pattern, use a regex tester tool (available online) to verify that it works as expected and matches the desired inputs.
Keep Patterns Simple: Avoid overly complex regex patterns, as they can be difficult to understand and maintain.
Provide User Feedback: If a user's input does not match the regex pattern, display a clear and helpful error message explaining the expected format. This will guide users on how to correct their input and improve the user experience.
By effectively using regex in NoteForms, you can enhance the quality of data collected through your forms, improve data consistency, and streamline data processing.
