I've sold the problem on redirects. Now if I submit an empty form it will redirect back to the login page then show the flashdata.
I had to edit my .htaccess file because the application is within a folder in the root folder.
Then I had to tinker on my model and controller codes to remove other errors.
At least for now that problem has been solved. I'll try to make a register, delete, and edit users functions to complete the user authentication.
Thanks for the help though! I'm sure to be back here and ask for some information.
By the way, I will be presenting the Codeigniter Framework on the Software Freedom Day on September here in our place. A brief overview of the framework for an audience of college students, with a sample project for them to be able to understand the framework.
I hope it would get their interest to try and use CI.
