What we have done• myPhpAdmin

– Created a database

– Tables

– Fields

• Inserted Data– Registration (this could be a student or tutor)

• Selected Data– Used as part of the authentication process

• Session Variables– If the authentication process was successful

• The include statement– Makes our job much easier


HO

PE

What we have done so far

• Applying user levels to your current users table– Registering as a tutor– Registering as a student

• Dynamically displaying different menus/links dependent on the user– Authorising the tutor– Authorising the student

• Allowing a tutor to upload a list of students for registration

What 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.

Recap

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”);

4. Execute the SQLmysql_query ($sql,$conn);

Our Database

only accounts for students! What about tutors and administrators

We need to expand our database

• There may be many resources– Each tutor will have resources– Resources are made available or not

• This could be within a set period

uploadResource.php

• What is the criteria?– make available?

• from start date / finish date

1. Get Resource

2. Get Start Date (available from)

3. Get Finish Date (available until)

4. Construct SQL based on 1,2 and 3

What 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


HO

PE

Assume 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


HO

PE

showStudentPage()

$currentDate = date('Ymd');$conn = mysql_connect("localhost","root","root");mysql_select_db("aceTraining",$conn);$sql = ("SELECT * FROM resource");$records = mysql_query($sql,$conn) or die (mysql_error());

while ($currentResource = mysql_fetch_array($records)) { echo "<ol>"; if ((str_replace("-", "", $currentResource['resourceStart']) <= $currentDate) && (str_replace("-", "", $currentResource['resourceFinish']) >= $currentDate)) { echo ("<li>" . "<a href='" . $currentResource ['resourceLocation'] . "'>" . $currentResource['resourceName'] . "</a></li>"); }

echo ("</ol>"); }

Satisfactory

• We have done enough to pass the webpage criteria of the assessment– don’t forget you also have a report– and a presentation– and an exam


HO

PE

Satisfactory• 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


HO

PE

Considerations• 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


HO

PE

Next?

• 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


HO

PE

Any Questions?

• Remaining time is for student support
