Student Advising System

Student Advising System Presented By: Kue Cha Raymond Tse

Purpose of Our Project • The existing problem with the current advising system. • Paper Work • Incomplete Paperwork • Late Registration

Proposed Solution • Student Advising System for students • Keep track of academic records • Course plan • Set appointment to meet with advisor

General design • Three tier Architecture • HTML • PHP/JavaScript • MySQL Database

ER diagram • ER Diagram

Database Tables • Number of tables CREATE TABLE student_info ( student_id INT UNSIGNED NOT NULL AUTO_INCREMENT, PRIMARY KEY (student_id), saclink VARCHAR(10) NOT NULL, last_name VARCHAR(20) NOT NULL, first_name VARCHAR(20) NOT NULL, middle VARCHAR(20) NULL, ssn INT(4) NOT NULL, phone VARCHAR(20) NOT NULL, email VARCHAR(100) NOT NULL UNIQUE, catalog_year VARCHAR(4) NOT NULL, graduation_date DATE NOT NULL );

Functions behind • Advisors/Administrator Side • View student records • Delete appointment of students • Change student status from pending/approved • Students Side • Add/Edit personal information • Add/Edit course information • Plan schedule • Make appointment

Function (Cont..) • Email notification • When user first register • Advisor Change status of students • Password recovery

Session • A session is a series of interactions between two communication end points that occurs during the span of a single connection. • The session is kept "alive" on the server as long as the user is logged on to the system. • The session is destroyed when the user logs-out from the system or after a predefined period of inactivity.

Session (cont) • session_start(); • It is required before any of your php/html code. • Session_destroy() • This will kill all the registered session variables. • It is used to create logout function. • Session_unset($_SESSION[‘user’]) • This will set created session variable into null. • It can also be used in logout function.

SessionExample: if ($_POST) { $tempName = $_POST ['username']; $tempPass = $_POST ['password']; $result = mysql_query ("SELECT * FROM members WHERE username = '$tempName' AND password = '$tempPass'") $found = mysql_num_rows ($result); if ($_POST) if ($found) { $_SESSION ['username'] = $tempName; $_SESSION ['password'] = $tempPass; $_SESSION ['logged'] = 'logged'; printf("<META http-equiv='REFRESH' content='0; url =index.php?action=%s'>", MEMBER); } else { #---------------- needs layout for invalid username and password -----------------# print(" Invalid username and password. Please try again. "); printf(" Click <a href ='index.php?action=%s'>here</a> to try again. ", LOGIN_PG); } } else { die(" Please log in. "); }

MD5 Encryption • Hashing algorithm • Generates 32 character ID • Harder to guess • Use it for Session ID or User’s password

MD5 Example: • Function getMD5() • { • //gives a new random password • $randomId = rand(); • $lengthOfString = 6; //how long you want the new password to be • $stringPosition = 12; //position to start getting characters, md5 hash will be 32 char string • $randomId = md5($randomId); //generate 32 char string • $temp = substr($randomId, $stringPosition , $lengthOfString);//change variables here because we want to send this plaintext back to the calling function (using a reference variable) so you will be able to read the password • $randomIdMD5 = md5($temp); //create our hash • return $randomIdMD5; • }//end getMD5
