Adding a some modifications to PHP source based YII framework.

I have bought an online form script and i need some modifications to be added as described: 1- Print all: Print all the entries with there attachments in numeric order. 2- Add 2 new fields/functions: A- Username = Civil id. B- Password = Random. After each submission user will receive an email with the random generated password so he can access his account. 3- Login screen for users and after login present another screen with these details: A- Full Name. B- Civil id. C- Date and time of submission. D- Application Status (Waiting for review/Rejected/Accepted). E- Note: Under the application status add a Note so users can see the note that admin has written for the user. For example: Your application has been denied for the following reason... etc. 4- Add new functions in admin panel: A- inside "Bulk actions" in users submissions screen add "Select all Waiting for review". B- Note field below the submissions. C- Submit button. After clicking on submit button all the selected submissions users will receive an email about their application status and a link to the login screen so they can login and check for their submission details. D- View attachments online. E- Select all specific Filed type. The script that i have bought for reference: [login to view URL]
