I would like your suggestions on how to proceed in making a control panel in PHP to manage different resources: it needs to let the user edit remote .xml, .php .js and Joomla's pages in a user-friendly manner. The user would not have access to the code, but only to images or text that they could change.
Create three systems.
To handle the page creation, deletion and template designs (closed to the end-user?)
To add, edit and remove resources like images, videos, texts, et cetera.
To make associations, like "I want this, this and that listed on that page".
The final engine should iterate through the associations, find the proper resources, and display them correctly using a template.
