I request the feature of being able to define external data sources, such as a mySQL data base, access it via php and run some calculations and change the appearance of text within a Hype Document.
Thanks for your feature request. For now, here's a technique for accessing mysql content via PHP: http://forums.tumult.com/t/ajax-php-db-query-within-hype/2540. There are also a few other example you may be able to adapt here.
Thank you - I will definitely review all these options. Much appreciated!
