Ok, Jerome did a great job helping me... but I keep getting stuck. For example, how do I grab the values in the php file and return it back to the Sencha Touch framework?
The documents are helpful, but they don't explain half of what I need. Just like the Ajax function, it shows me how to include the function and how to use it; but not very well on how to manage the data being sent and returned... How did you all learn and become experts in this framework?
What's done on the server/database side really has nothing to do with this framework. That's all written in other languages like PHP, RPG, etc. That website, Parse.com, offers a very easy to use API that handles the database calls and has many examples of how to use them. Their databases are also very organized and visual.
I understand that it's not part of the framework, but when I use the Ajax function, how do I know what format the data is being passed in? Most of the time, in PHP, I'll use either the "$_GET['fieldname']" or "$_POST['fieldname']" to grab the data. Parse.com looks like a nice site and well known, but I already have my own database and I have a php mobile site already buit. I would just like to switch it over and use the UI/Theme Sencha Touch has to offer..
using a jsonbeautifier you can see then how to access the values.
