I Was Here – PHP Student Attendance Management System

I Was Here is a simple, free, and open-source PHP Student Attendance Management System. It has zero dependencies on third-party frameworks and is completely built using pure HTML, CSS, Javascript, PHP. This should help developers to quickly build on – No need to learn any additional frameworks, no added script bloating.

LICENSE

I-Was-Here is released under the MIT License. You are free to use it for your own personal and commercial projects, modify it as you see fit. On the condition that there the software is provided “as-is”. There are no warranties provided and “no strings attached”. Code Boxx and the authors are not liable for any claims, damages, or liabilities.

 

REQUIREMENTS

I-Was-Here has not been extensively tested, but it is developed and works on a WAMP8 (Windows Apache MySQL PHP 8) server. Requirements:

• Apache Mod Rewrite
• PHP PDO Extension
• Best to have at least PHP 7

 

INSTALLATION

As for the “installation”… There is no installer, but this should be simple enough:

1. Create a database and import the core/iwashere.sql file.
2. In core/Core.php, change the database settings (A2), host (A4), and email (A5) to your own.

That’s all. The default user is “admin@iwh.com” and the password is “123456“. Remember to change it later.

 

 

 

STEP 1) REGISTER TEACHERS & STUDENTS

First, register the teachers and students under the “Users” tab. You can add them one-by-one… But the faster way is to mass import a CSV file with the name, email, and password. For example:

Jon Doe	jon@doe.com	123456
Jan Doe	jan@doe.com	654321
Jay Doe	jay@doe.com	2254567

 

STEP 2) REGISTER COURSES

Next, register your available courses under the “Courses” tab. Same old story, you can do it manually one by one, but importing is faster. This time in the order of course code, course name, description. For example:

MATH	Basic Math	Basic Mathematics course.
ENG	Basic English	How to ABC.
SCI	Basic Science	For kids 5-55.

 

 

STEP 3) ASSIGN STUDENTS TO COURSES

With that, we can now assign students to their respective courses. The painful way is to assign students one by one with their email… But you catch the drift, just importing a whole list of emails is faster. Example:

jon@doe.com

jan@doe.com

jay@doe.com

 

STEP 4) REGISTER CLASSES

Now that all the necessary data is in, register the classes.

 

STEP 5) TAKE ATTENDANCE

Lastly, Captain Obvious, take the attendance of the class.

 

 

 

FOLDER STRUCTURE

• core/ Holds the libraries and API files.
• pages/ The HTML pages
• public/ Javascript, CSS, images, whatever public assets.

Yes, there are only 3 folders in the entire system.

API REQUESTS

There are only 3 sets of API handlers:

• http://SITE.COM/api/Class Class-related requests.
• http://SITE.COM/api/Course Course-related requests.
• http://SITE.COM/api/User User-related requests.

Just do a POST request followed by the required parameters.

• $_POST['req'] is for open requests, no user verification is required.
• $_POST['reqS'] for student functions.
• $_POST['reqT'] for teacher functions.

 

CLASS API REFERENCE & EXAMPLES

reqT : "save"
code : "BIO234" // COURSE CODE
id : 1 // TEACHER IN CHARGE (USER ID)
date : "2077-06-05 12:30:00" // CLASS DATE TIME
desc : "Bio class" // DESCRIPTION (OPTIONAL)
cid : 888 // CLASS ID (ONLY IF EDITING)

reqT : "del"
id : 888 // CLASS ID

reqT : "attend"
cid : 888 // CLASS ID
uid : 999 // USER (STUDENT ID)
attend : 1 // 1 FOR PRESENT, 0 FOR ABSENT

STEP 1) CREATE/MODIFY DATABASE TABLES

Add your new tables, modify the existing ones.

 

STEP 2) ADD/UPDATE SYSTEM MODULE

Create a core/LIB-Module.php, define class Module, add functions inside. For example, to add a new report module – Create core/LIB-Report.php.

class Report {
  function getStudentAttend ($id) {
    return $this->core->fetchAll(
      "SELECT * FROM `attendence` WHERE `user_id`=? ORDER BY `sign_date` DESC",
      [$id]
    );
  }
}

That’s it. The new module can now be loaded via $_CORE->load("Report") and the new function can be accessed via $_CORE->Report->getStudentAttend().

 

STEP 3) ADD/UPDATE API ENDPOINT (OPTIONAL)

Create core/API-Module.php. For example, core/API-Report.php can be accessed at http://site.com/api/Report. How the API work is simple, we just send a $_POST['req'] OR $_POST['reqS'] OR $_POST['reqT] followed by the required parameters.

// (A) TEACHER REQUESTS
$_CORE->load("Report");
if (isset($_POST['reqT'])) { switch ($_POST['reqT']) {
  // (A0) INVALID
  default:
    $_CORE->respond(0, "Invalid request");
    break;
 
  // (A1) GET STUDENT ATTENDANCE
  case "getAttend":
    $records = $_CORE->Report->getStudentAttend($_POST['id']);
    $_CORE->respond(1, "OK", $records);
    break;
}}

That’s all. We can now send $_POST['reqT']="getAttend" and $_POST['id']=123 to http://site.com/api/Report to fetch the report in a JSON-encoded string.

 

STEP 4) ADD/UPDATE HTML CSS JAVASCRIPT

• Add new pages with pages/PAGE-name.php. For example, pages/PAGE-report.php will be accessed from http://site.com/report.
• Add new admin pages with pages/ADMIN-name.php. For example, pages/ADMIN-report.php will be accessed from http://site.com/admin/report.
• Take note – PAGE-name.php can only be accessed by users who are signed in, ADMIN-name.php can only be accessed by teachers.

That’s about it. Just reverse engineer and copy from the existing libraries, API, and pages… You will see the development pattern here.

 

 

I FORGOT THE PASSWORD/DELETED ALL ADMIN ACCOUNTS

Create an “account recovery” script to create a new account, or update an existing one.

require "core/Core.php";
$_CORE->load("User");
$_CORE->User->save("NAME", "EMAIL", "PASSWORD", "T", OPTIONAL-USER-ID);

Run and delete this afterward…

 

MIGRATED TO A NEW DOMAIN

• Simply update URL_BASE in core/Core.php.
• Delete .htaccess, let the system will regenerate a new one.
• Clear the browser cache to prevent irritating cache redirects.

Done. If you have some extra URL rewrite to add – Go ahead and modify __construct() in core/LIB-Core.php.

 

NOT WORKING. DON’T KNOW WHY.

Update public/common.js section E1 – opt.debug = true. Reload the page and see the error message.
