Need changes in the Code

Hello, I need a change to the firmware from this project. [login to view URL] The project delivers the current firmware as open source code and is written with plaformio. The following change will be for needed a school with an access management project due to Corona. There is a MySQL database and a web interface (PHP) with the RFID access data of the children and teachers and since several RFID access points are used and the accesses have to be maintained centrally, we need a way to check the access data against the database. I imagined it like this: 1. Under Settings-> General Settings should have 2 additional entries. 1. a switch on / off - use external database 2. Input field - path to the PHP script (e.g. [login to view URL]) 3. Input field - HASH (assigned by the admin) 2. If the switch for using the external database is on, the access check should only be carried out locally and if no user was found, the external PHP script should be requested. Example: no local user available, check http: //[login to view URL] The response from the script should be true or false #### In addition, the duration of the signal for opening the lock is too short, this can be extended because nobody can open the door that fast :-) Kind regards
