Your CodeIgniter setup has several common issues that can prevent it from running in your browser. Here’s a checklist and fixes based on your provided info: --- ### 1. **Case Sensitivity in URL and Folder Names** - Windows is case-insensitive, but Apache (on XAMPP) and CodeIgniter are case-sensitive in URLs and file/folder names. - Your folder is `T2-Orfanel` but you are accessing `http://localhost/t2-ORFANEL/public/index.php/activity` (all caps). - **Fix:** Use the exact case as your folder name in the URL: `http://localhost/T2-Orfanel/public/index.php/activity` --- ### 2. **Base URL Configuration** In `app/Config/App.php`: ```php public string $baseURL = 'http://localhost/T2-Orfanel/public/'; ``` - This is correct **if** your folder is named `T2-Orfanel` (case-sensitive). --- ### 3. **.env Database Settings** Your `.env` should look like: ``` database.default.hostname = localhost database.default.database = db_surname database.default.username = root database.default.password = database.default.DBDriver = MySQLi database.default.DBPrefix = database.default.port = 3306 ``` - Make sure there is **no space** after `=`. - Make sure the database `db_surname` exists in phpMyAdmin. --- ### 4. **Controller Syntax Issues** Your `app/Controllers/Activity.php` is incomplete and missing PHP tags and class structure. **It should look like this:** ```php findAll(); return view('activities/index', $data); } public function create() { return view('activities/create'); } public function store() { $model = new ActivityModel(); $model->save([ 'name' => $this->request->getPost('name'), 'description' => $this->request->getPost('description'), ]); return redirect()->to('/activity'); } } ``` --- ### 5. **View Files** **app/Views/activities/index.php** ```php Activity List

Activity List

Add New Activity

``` **app/Views/activities/create.php** ```php Add Activity

Add Activity

``` --- ### 6. **Routes** Your `app/Config/Routes.php` should have: ```php $routes->get('/activity', 'Activity::index'); $routes->get('/activity/create', 'Activity::create'); $routes->post('/activity/store', 'Activity::store'); ``` --- ### 7. **Database Table** Make sure you have a table called `activities` with at least these columns: - `id` (int, auto_increment, primary key) - `name` (varchar) - `description` (text) - `created_at` (datetime, nullable) - `updated_at` (datetime, nullable) --- ### 8. **Accessing the App** - Use: `http://localhost/T2-Orfanel/public/index.php/activity` - Or, if you have mod_rewrite enabled and `.htaccess` is working, you can use: `http://localhost/T2-Orfanel/public/activity` --- ### 9. **Common Mistakes** - Wrong folder name or case in URL. - Missing PHP tags or class structure in controllers. - Database not created or table missing. - Wrong baseURL in `App.php`. - Not running XAMPP/Apache/MySQL. --- **If you still get an error, please copy the exact error message and paste it here for more help.**
