How to Add a Regex Condition to Your Input Fields?

Regular expressions (regex) are versatile tools for ensuring that user input meets specific criteria. By adding regex validation in NoteForms, you can enhance data accuracy, enforce consistency, and streamline your form's performance.


Why Use Regex in Forms?

Regex allows you to define rules for data entry, ensuring high-quality and structured input. Common use cases include:

Email Validation: Check for the presence of "@" and a valid domain.

Phone Number Formatting: Verify digit count and structure.

Password Strength: Require combinations of letters, numbers, and symbols.

Character Restrictions: Limit inputs to specific characters like letters or numbers.

By implementing regex, you can prevent invalid data and guide users toward accurate submissions.
