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
Common Causes
- Validation functions deleted as 'dead code'
- Form submit handler no longer calls validate()
- Input onChange handlers not updating validation state
- Validation error messages not displaying
- 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' />.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

What's the difference between client and server validation?
Client validation is UX (immediate feedback). Server validation is security (trust no client). Always validate both.
What validation library should I use?
react-hook-form for performance, Formik for features, Yup/Zod for schema validation. Choose based on needs.
