The goal of this project is only to create a callback function for the plugin named "WP File Download" of JumeUnited. On each page load, a shortcode of the plugin is loaded, which creates a view of 1. a file directory, 2. or a single WP File. I am looking for a call-back functionality that creates access for a logged-in user only if a function returns true. As we speak about security, the code must be deeply integrated with the core code of the plugin. User logs in --> user opens Page XYZ --> WP File Download core loaded --> calls function ABC --> function ABC returns true --> WP File Download gives defined access to the file(s) or directory I am not looking for user-based access, nor do I want a user group-defined access (which is the standard way of this plugin). Access shall only be given if a certain callback function returns true. Annotation: -------------------- Any bid that is an autoresponder will be deleted. Please provide the following answers (only those will be in the bid process): a) Why are you an expert on JoomUnited and esp. WP File download? b) How do you integrate the call-back function (describe the way) Only 1 Milestone will be defined, which is "YES, WP File Download gives access to a file or directory if a function is called and returns true, OR no WP File Download access is given if the function returns false.

Hello, I can implement a server-side callback gate inside WP File Download so access to a file or directory is granted only when your function returns true and denied when it returns false—wired at the exact decision points used by the shortcode render and the download controller, not just a front-end hide. This will run for logged-in users on every page load, integrate cleanly with the plugin’s core flow, and prevent direct-link bypasses while keeping the code maintainable for updates. Questions: – What’s the main goal you want this software to achieve for your business? – Do you already have any designs or ideas for how it should look and feel? – Will the system need to connect with any other tools or platforms you currently use? I am a TOP Rated Freelancer, and you can check my reviews here as well: https://www.freelancer.com/u/techsty2014 Looking forward to potentially working together on this project.
