PEWhat we have done so far

PEWhat we have covered

Ace training requires a new system for students that enrol onto their course(s). There will typically be three methods of enrolment: from a list, by a tutor, or by a student. Students that register themselves require authorising by the tutor. Tutors are created by administrator(s) after the credentials of the tutor has been checked. To become a course tutor the individual will register as a tutor. The tutor will have the facility of uploading various resources, such as powerpoint presentations and documents. Once uploaded they should either: be made available to the student, not available or available within a specified date range.

1. Create a connection to the SQL Server$conn = mysql_connect (“localhost”, “root”, “root”);

2. Select the databasemysql_select_db (“database” , $conn);

3. Construct the SQL statement$sql = (“what I want to do with the database”);

PEWhat we have done

• Allowed the tutor to upload a resource– specified start date– specified finish date– specified resource location– specified resource name

• Next?– displaying available resources

• dependent on start and finish date

www.hope.ac.uk Faculty of Sciences and Social Sciences

HO

PEAssume student is logged in!

• display student page– we have prepared for this in login.php– function called showStudentPage()

• display resources available for download– ie, what the tutor has uploaded

PESatisfactory

• Student and Tutor can register– tutor must authorise student, administrator must authorise tutor

• Student and Tutor can log in• Tutor can

– authorise pending students– enrol students from a list– upload resources (powerpoint, documents, pdf, etc)– resources can be made available within a given period

• Students can– view available resources within the given period

www.hope.ac.uk Faculty of Sciences and Social Sciences

HO

PEConsiderations

• Tutors– we have not accounted for tutor(s) delivering multiple courses– we haven’t allowed for the tutor to change start and finish times (or

to delete) of uploaded files– we don’t allow the tutor to structure resources (weeks, content

type, file type)– Tutors can not change their details (email address, password)

• Students– we have not accounted for student(s) enrolled for a particular

course (or multiple courses)– we have not facilitated the tracking of student progress– we don’t allow the student to change their details

PENext?

• Example code is online• Next week is a drop-in support session– students that can not get this working should

come and speak with me as soon as possible
