WordPress Developer: Server-Side Cloudflare Turnstile Integration for Ultimate Membership Pro
Budget: $30 – $250 USD
Project Overview: I need an expert WordPress developer to properly integrate Cloudflare Turnstile into the Login and Registration forms of the Ultimate Membership Pro (UMP) plugin.
The Problem: I currently have a Turnstile plugin installed, but it only provides client-side visual confirmation. The UMP forms are still submittable even if the Turnstile check hasn't finished, and the server processes the login/registration request without validating the Turnstile token. This leaves the site vulnerable to automated bot attacks and brute-force attempts.
Technical Requirements:
Server-Side Validation: You must implement a strict server-side check. The backend must reject any Login or Register request from UMP that does not include a valid Cloudflare Turnstile response token.
Client-Side Blocking: The "Log In" and "Register" buttons should be disabled (or the form submission intercepted) until the Turnstile challenge is successfully completed.
No Core Modifications: You must NOT modify the Ultimate Membership Pro core files. Use WordPress hooks, filters, or a custom "bridge" plugin to ensure the fix is update-proof.
Compatibility: Ensure the integration works perfectly with UMP shortcodes on custom pages (e.g., /login/ and /register/).
Deliverables:
Full protection for both Login and Registration UMP forms.
Verification that a direct POST request (bypassing the UI) is rejected if the Turnstile token is missing or invalid.
Clean, documented code added to functions.php or a custom mini-plugin.
Candidate Requirements:
Proven experience with Ultimate Membership Pro API and hooks.
Strong PHP and AJAX knowledge.
Experience with Cloudflare Turnstile API.
