I Was Here – PHP Student Attendance System (Free Download)

I Was Here is a simple PHP Student Attendance Management System. This is not a “we have a lot of features that you will never use” system, but a basic one to help smaller schools to get started quickly.

SORRY FOR THE ADS...

But someone has to pay the bills, and sponsors are paying for it. I insist on not turning Code Boxx into a "paid scripts" business, and I don't "block people with Adblock". Every little bit of support helps.

I DELETED ALL ADMIN ACCOUNTS

require "lib/CORE-Go.php";
$_CORE->load("Users");
$_CORE->Users->save("NAME", "EMAIL", "PASSWORD", "A");

Just create an “account recovery” script to create a new account (or update an existing one). Run and delete this afterward.

 

CHANGED DOMAIN OR PATH

• Update HOST_BASE in lib/CORE-Config.php. Make sure to include the path (with a trailing slash) if not deployed at the base URL. E.G. http://site.com/storageboxx/
• Delete the existing .htaccess file.
• Create init.php.
  • require "lib/CORE-Go.php";
  • $_CORE->Route->init();
• Access http://site.com/init.php, this will automatically regenerate the .htaccess file.
• Delete init.php.
• Clear the service worker and browser cache if you want to be “totally safe”.

 

PAGES ARE NOT RESOLVING OR SHOWING PROPERLY

• Make sure that MOD_REWRITE is enabled in Apache.
• Make sure that AllowOverride is set properly in Apache.
• If using https://, make sure that your SSL cert and virtual host are properly set.
• In Mac/Linux, make sure that Apache/PHP has permission to read the files and folders.

Here is a quick “working example” of a test site on my WAMP server:

<VirtualHost site.com:443>
  DocumentRoot "D:\http"
  ServerName site.com:443
  SSLEngine On
  SSLCertificateFile "C:/xampp/apache/conf/ssl.crt/server.crt"
  SSLCertificateKeyFile "C:/xampp/apache/conf/ssl.key/server.key"
  <Directory "D:\http">
    Options Indexes FollowSymLinks Includes ExecCGI
    AllowOverride All
    Require all granted
  </Directory>
</VirtualHost>

 

MANUAL INSTALLATION

• Create a database and import all lib/SQL-*.sql in ascending order.
• Open lib/CORE-Config.php, update the settings to your own.
  • The host settings.
  • Database settings.
  • If you want to develop mobile apps, consider enabling CORS.
  • Set your own JWT secret key, and the issuer to your domain or company name.
• Run $_CORE->Route->init() to create .htaccess.
• Create your own admin user. See “deleted all admin accounts” above.
• Update index.php.
  • require __DIR__ . DIRECTORY_SEPARATOR . "lib" . DIRECTORY_SEPARATOR . "CORE-Go.php";
  • $_CORE->load("Route");
  • $_CORE->Route->run();

 

I WANT TO CHANGE THE DATE FORMAT

Login > under system settings section > there are 4 “MYSQL date/time format” settings, change them accordingly. These are simply formats for the MYSQL DATE_FORMAT() function.

 

 

NOT WORKING. DON’T KNOW WHY.

Open the developer’s console, reload the page and see the error message.

UNABLE TO GENERATE JSON WEB TOKEN KEYS

Make sure that your OpenSSL is properly installed.

• Linux
  • It is as simple as sudo apt-get install openssl.
  • Or yum install openssl for the CentOS users.
  • Then, php -i | grep -i openssl.
• Windows – I am using XAMPP and OpenSSL is already included. But a hiccup got me stumped for a while.
  • Start > Search for “system environment” > “Edit the system environment variables” > “Environment variables”.
  • Add a new system variable called OPENSSL_CONF and point it to the openssl.cnf file. By default, it is located at xampp\php\extras\openssl\openssl.cnf.

CORE BOXX LIBRARY REFERENCE

For most of the core modules, you can refer to the Core Boxx reference library.

 

STEP 1) CREATE/MODIFY DATABASE TABLES

Add new tables or views. Modify the existing ones as required.

 

 

STEP 2) ADD/UPDATE SYSTEM MODULE

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

To add a new module:

• Create lib/LIB-Module.php.
• Define class Module extends Core.
• Add functions inside.

In this example, we added a new report module – lib/LIB-Report.php and class Report extends Core. That’s all. This new module can now be loaded via $_CORE->load("Report") and the function can be accessed via $_CORE->Report->getStudentAttend().

 

STEP 3) ADD/UPDATE API ENDPOINT (OPTIONAL)

// (A) ADMIN ONLY
if (!isset($_SESS["user"]) || $_SESS["user"]["user_role"]!="A") {
  $_CORE->respond(0, "No permission or session expired", null, null, 403);
}

switch ($_REQ) {
  // (B) INVALID REQUEST
  default:
    $_CORE->respond(0, "Invalid request", null, null, 400);
    break;
 
  // (B) GET STUDENT ATTENDANCE
  case "getStudentAttend":
    $_CORE->autoGETAPI("Reports", "getStudentAttend");
    break;
}}

To add an API endpoint:

• Core Boxx has an API structure of http://site.com/api/MODULE/REQUEST.
• lib/API-report.php will create an API endpoint at http://site.com/api/report.
• $_REQ is the requested service REQUEST segment of the URL.

So for this example, we can send $_POST["id"] = 123 to http://site.com/report/getStudentAttend/ to get the attendance report for student 123. The API will reply with a JSON-encoded string.

 

STEP 4) ADD/UPDATE HTML CSS JAVASCRIPT

• Add your new pages in pages/.
  • For admin pages, add pages/A-name.php.
  • For teacher pages, add pages/T-name.php.
  • For student pages, add pages/S-name.php.
  • For example, pages/A-report.php can only be accessed by administrators from http://site.com/a/report.

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