This plugin extends a widely-used form builder by adding regular expression (RegEx) validation to its single-line text fields. It is designed for site builders and developers who need precise control over the format of data submitted through web forms, ensuring entries match specific patterns before acceptance.

• RegEx Pattern Validation: Define a custom regular expression pattern that user input must match. This allows you to enforce formats for data like phone numbers, postal codes, product SKUs, or custom identifiers directly within the form field settings.
• Custom Validation Messages: Provide a clear, user-friendly error message that displays when the entered data does not match the specified pattern. This improves the user experience by explaining exactly what format is required.
• Simple Integration: The functionality is added as a new option in the advanced settings tab for single-line text fields. There is no need to edit theme files or write additional code to activate the validation.
• Granular Control: Apply validation on a per-field basis, allowing different patterns and messages for different text inputs within the same form. This is useful for forms collecting multiple types of structured data.
