Basically i generate a "XML" model & CRUD , and use xml/index to receive their $_POST request
this is some example request
User Sign Up (function = signUP)
Submit($_POST): first name, last name, password, email address, gender, date of birth,function=""
Return(XML Format): Sign Up status (successful with user ID, failed, or email taken, etc)
User Sign In (function = signIn)
Submit($_POST): email, password
Return(XML Format): Sign In status (successful with user ID or failed)
i also try to create a test form in "xml/test"
after submit will respond format like this
This is format that mobile developer request.
but than after developer test in their mobile systems, they show "[color="#FF0000"]400 bad request,your browser send a request that this server could not understand[/color]".
