I have two text input fields that stay strictly in sync with a controlled data source. Users fill them in only by: • entering a numeric ID that instantly auto-completes both fields, or • typing a few characters and choosing one of the suggested matches that Free-form entries have to be blocked so the data that finally reaches the server is always a valid, predefined text string that comes from the data source. The suggestions are supplied from an internal list or endpoint I already maintain; If something here is unclear, let me know early so we can keep the scope tight and turnaround quick. Video 1 and 2 shows what the app does. Video 3 shows what it shouldn’t do

Hello, You’re not just building two inputs , you’re protecting the data from drifting out of sync. That locked, suggestion-only flow is exactly where subtle bugs usually appear, and I can wire it cleanly. I’ve built controlled UI inputs with strict autocomplete, enforced selection-only behavior, and server-side fallback validation using vanilla JS and lightweight framework patterns. I’ll make both fields stay synced to your source list/endpoint, allow ID lookup or filtered suggestions, and block all free-form edits, paste attempts, and post-fill changes. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you’d like, I can review the videos first and map the interaction rules before implementation. Should both inputs always resolve from the same dataset and selected record, or can they map independently? Could you confirm whether the two fields always share the same source value or can resolve independently? Best regards, Asad

Hi, I can implement this validation so both input fields always stay synchronized with your controlled data source. Users will only be able to select valid entries via numeric ID lookup or autocomplete suggestions, while free-form text will be blocked to ensure only approved values are submitted to the server. I'll review your videos, integrate the logic into your existing application, and thoroughly test the workflow to ensure invalid input is prevented without affecting usability. I can start immediately and deliver a clean, reliable solution. Best regards, **Muhammad Rizwan LA**

Hello, It looks like you're looking for a way to manage two text input fields that stay perfectly in sync with a controlled data source. Users will be able to input a numeric ID for instant auto-completion or type a few characters to choose from a dropdown of suggestions. Once an option is selected, it needs to be locked to prevent any further edits, ensuring the data sent to your server is always valid. With 7+ years of experience in web development, I can implement this functionality using vanilla JavaScript or a lightweight framework, while also ensuring that the client-side requests are efficiently handled. I’ll integrate with your internal list or endpoint for suggestions and add server-side validation as a fallback to maintain data integrity. One thing I'd love to clarify is how you envision the user experience when suggestions are displayed. Do you have specific design or interaction preferences in mind? Best regards, Ivan Mandinski

Greetings, To ensure your two text input fields stay in perfect sync with the controlled data source, I would create a solution that allows users to populate these fields through numeric IDs or character-based suggestions. This would involve implementing a responsive autocomplete feature that interacts with your internal list efficiently, ensuring that options trigger correctly and populate both fields simultaneously. Once a value is selected, I’ll ensure that the fields lock to prevent any edits, maintaining data integrity. This would involve client-side validation to block free-form entries, supplemented by server-side validation for added reliability. With my skills in JavaScript, PHP, and API integration, I can deliver a clean, user-friendly experience while keeping performance at the forefront.

Hey, locking those inputs after selection is the right move to keep your data clean. I’d handle the state by toggling the read-only attribute immediately upon a valid selection to prevent any manual overrides. The real challenge is keeping the sync logic snappy so the user doesn't feel a delay when the ID triggers the auto-fill. Are you planning to handle the server-side validation with a simple API check or a hidden form field?

Hi, this is a clean, well-scoped task - happy to take it on. My approach: bind both inputs to a single controlled state object so a numeric-ID match or a picked suggestion is the only way to set a value; once set, the fields go readonly/disabled (blocking keystrokes and paste events) until a reset action clears them. I'll debounce the free-text lookup against your existing endpoint/list for the dropdown suggestions, and add a lightweight server-side check on submit so a tampered client can't push an invalid string through. Can start immediately once you confirm the suggestion source format (endpoint vs. local list) - happy to work from whichever you already have.

Hi, I can build the controlled auto-suggestion inputs you described. The two fields will stay in sync, and only valid entries from your data source will be accepted. I'll use vanilla JavaScript for the frontend and PHP with MySQL for the backend, which is a reliable, lightweight stack for this kind of feature. I'll implement client-side blocking of free-form text, server-side validation to reject any invalid data, and parameterized queries to prevent injection. The autocomplete will fetch suggestions from your endpoint as the user types, and entering a numeric ID will instantly populate both fields. I'll also add rate limiting on the suggestion endpoint and keep logging minimal for privacy. Could you confirm the format of the data source (e.g., JSON endpoint or database table) and whether you need the solution integrated into an existing page or as a standalone demo? I can deliver this in around 10 days.

The lock-after-select is the real make-or-break here—users can trigger population by ID or by typed search, but any edits after that must be blocked (no input, no focus, no paste). I’ve set up this exact pattern for KYC and admin tools before, using React.js with clean server validation. I’d build this with React.js or plain JS if you want it even lighter, depending on your existing stack. Inputs talk to your endpoint for suggestions on debounce, only known values allowed through, everything validated again on submit. No free entry, no stale option possible. Which framework is your main app in right now—pure JS or something like React? Pradeep

Based on your description, the goal is to ensure that both text fields can only contain values that exist in your controlled data source, preventing any free-form or invalid entries from reaching the server. I'll review the current implementation and update the autocomplete workflow so users can either enter a valid numeric ID that populates both fields automatically or select a value from the suggestion list. Any manually typed value that doesn't match an approved record will be rejected or cleared before submission. I have 10+ years of experience with PHP, JavaScript, jQuery, AJAX, MySQL, and form validation, and I regularly implement controlled-input systems, autocomplete components, and server-side validation to maintain data integrity. I'll ensure validation is enforced both in the frontend and backend so invalid data cannot be submitted even if client-side checks are bypassed. I'm open for further quick discussion and ready to start NOW.
