I have a work assignment, and I don't have any alternative; I have to use the qooxdoo framework.
How can I do a query with MySQL and PHP using this framework? In the examples present in the site, all tables use random values or JSON values, but in this case, I need PHP.
I know that I can't use PHP code inside a JavaScript file, so is Ajax the unique solution?
How I can solve that?
You write a PHP RPC service which provides the data to your qooxdoo application. You can find more input on this in PHP RPC (qooxdoo documentation).
