The code is in the link because is in a folder system.
PROBLEM:
I have an MVC architecture. Inside the view I have a class that contains a registration form that is in the initial_shield class. The form field data are sent to a script that contains an ajax this ajax will send the information to the class control and then there will be a return to the script by the function (done).
The error is happening in the User_dao class, every time I try to include the connection class present in the singleton package I get an error which is issued by the done function of ajax.
In the code I commented the inclusion but you can withdraw the comment
of the include_once of the User_date class and enter the data, which will see the error.
This is the image of the error when I include the connection class:
