Cursor ui

Form Validation Logic Removed by Cursor

After Cursor refactored your form code, client-side validation was removed. Forms now accept invalid input and submit it to the server, wasting resources and potentially causing errors.

Validation functions or checks were deleted during the refactoring.

Error Messages You Might See

Form submitted with empty fields Invalid email accepted No validation errors shown Server rejects invalid data
Form submitted with empty fieldsInvalid email acceptedNo validation errors shownServer rejects invalid data

Common Causes

  1. Validation functions deleted as 'dead code'
  2. Form submit handler no longer calls validate()
  3. Input onChange handlers not updating validation state
  4. Validation error messages not displaying
  5. HTML5 validation attributes removed

How to Fix It

Add validation function: function validate(data) { if (!data.email) return 'Email required'; }. Call on form submit. Show errors: {errors.email && <span>{errors.email}</span>}. Use libraries: react-hook-form, formik. Add HTML5: <input required type='email' />.
