CRUD adalah singkatan dari Cread Read Update Delete. Berikut penjelasannya:
5. membuat model untuk table, pertama buat file baru pada
list.php
new_form.php
edit_form.php
8. Membuat fitur hapus data pada file list php
Hasil:
- Create yang berarti membuat sebuah data baru
- Read yang berarti membaca atau menampilkan suatu data yang tadinya berada di database
- Update yang berarti mengedit sebuah data dari database
- Delete yang berarti menghapus data dari database
Langkah-langkah pembuatan :
1. Buat tabel sebagai database di localhost/phpmyadmin
2. Edit menyesuaikan dengan database di database.php
4. lalu lakukan konfigurasi pada
config/autoload.php $autoload['libraries'] = array('database', 'session');
