Update custom components working on Joomla 3.1 to make them work on the newest Joomla

Job ID: 37445738

Budget: €30 – €250 EUR

Dear Freelancer,
we use many PHP scripts for our laser tag game, which are accessible via our Joomla 3.1 website, hosted on an Apache web server with a PHP version 7.3.
The scripts work with partly outdated methods like JRequest and JFactory::getDbo(). We need somebody with sufficient knowledge of the Joomla-PHP-Ajax Framework to make them ready for the new versions of Joomla and PHP.
We would like to ask you to rewrite the attached scripts so that they are compatible for Joomla 5.0. The PHP version will be upgraded to 8.2 and the MySQL database to MySQL 8.0. You are also welcome to optimize the scripts or functions.
We will send you a download link of our compressed website if you are interested.
Under "files" you will find the scripts that are relevant. The folder "neues_design" contains the whole website.
Please treat all data responsibly.
Thanks a lot!
