Let’s get started.
CodeIgniter 4 Installation
To create a CodeIgniter 4 setup run this given command into your shell or terminal. Please make sure composer should be installed.
$ composer create-project codeigniter4/appstarter codeigniter-4
Assuming you have successfully installed application into your local system.
Create Database
To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.
We will use MySQL command to create database. Run this command into Sql tab of PhpMyAdmin.
CREATE DATABASE codeigniter4_app;
Successfully, we have created a database.
Database Connection
Open .env file from project root.
Search for DATABASE. You should see the connection environment variables into it. Put your updated details of database connection string.
#-------------------------------------------------------------------- # DATABASE #-------------------------------------------------------------------- database.default.hostname = localhost database.default.database = codeigniter4_app database.default.username = root database.default.password = root database.default.DBDriver = MySQLi database.default.DBPrefix =
Now, database successfully connected with the application.
Environment (.env) Setup
When we install CodeIgniter 4, we will have env file at root. To use the environment variables means using variables at global scope we need to do env to .env
Either we can do via renaming file as simple as that. Also we can do by terminal command.
Open project in terminal
$ cp env .env
Above command will create a copy of env file to .env file. Now we are ready to use environment variables.
Enable Development Mode
CodeIgniter starts up in production mode by default. You need to make it in development mode to see any error if you are working with application.
Open .env file from root.
# CI_ENVIRONMENT = production
// Do it to
CI_ENVIRONMENT = development
Now application is in development mode.
Create Migration
Open project into terminal and run this command to create migration file.
$ php spark make:migration add_posts
It will create a file –
- Migration file – 2022-09-07-031252_AddPosts.php inside /app/Database/Migrations folder.
Open Migration file and write this complete code into it.
<?php namespace App\Database\Migrations; use CodeIgniter\Database\Migration; class AddPosts extends Migration { public function up() { $this->forge->addField([ 'id' => [ 'type' => 'INT', 'constraint' => 5, 'unsigned' => true, 'auto_increment' => true, ], 'title' => [ 'type' => 'VARCHAR', 'constraint' => 50, 'null' => false ], 'body' => [ 'type' => 'TEXT', 'null' => true ] ]); $this->forge->addPrimaryKey('id'); $this->forge->createTable('posts'); } public function down() { $this->forge->dropTable('posts'); } }
Run Migration
Next,
We need to create table inside database.
$ php spark migrate
This command will create table – posts inside database.
Insert Bulk Data – Query Builder Method
Let’s create a controller file.
Controller File
To create a controller, run this command.
$ php spark make:controller PostController
It will create PostController.php inside /app/Controllers folder.
Open PostController.php and write this complete code into it.
<?php namespace App\Controllers; use App\Controllers\BaseController; class PostController extends BaseController { public function __construct() { $this->db = db_connect(); } public function index() { $builder = $this->db->table("posts"); $data = [ [ 'title' => 'Custom Title', 'body' => 'Post Body New' ], [ 'title' => 'Custom Title 2', 'body' => 'Post Body New 2' ], [ 'title' => 'Custom Title 3', 'body' => 'Post Body New 3' ], [ 'title' => 'Custom Title 4', 'body' => 'Post Body New 4' ] ]; $builder->insertBatch($data); } }
Route
Open Routes.php from /app/Config folder. Add this route into it.
//... $routes->get("data", "PostController::index");
URL: http://localhost:8080/data
Output

Insert Bulk Data – Using Model
Let’s create a model and a controller file.
Model File
$ php spark make:model Post
It will create a model Post.php inside /app/Models folder.
Open Post.php and write this complete code into it.
<?php namespace App\Models; use CodeIgniter\Model; class Post extends Model { protected $DBGroup = 'default'; protected $table = 'posts'; protected $primaryKey = 'id'; protected $useAutoIncrement = true; protected $insertID = 0; protected $returnType = 'array'; protected $useSoftDelete = false; protected $protectFields = true; protected $allowedFields = [ 'title', 'body' ]; // Dates protected $useTimestamps = false; protected $dateFormat = 'datetime'; protected $createdField = 'created_at'; protected $updatedField = 'updated_at'; protected $deletedField = 'deleted_at'; // Validation protected $validationRules = []; protected $validationMessages = []; protected $skipValidation = false; protected $cleanValidationRules = true; // Callbacks protected $allowCallbacks = true; protected $beforeInsert = []; protected $afterInsert = []; protected $beforeUpdate = []; protected $afterUpdate = []; protected $beforeFind = []; protected $afterFind = []; protected $beforeDelete = []; protected $afterDelete = []; }
Controller File
To create a controller, run this command.
$ php spark make:controller PostController
It will create PostController.php inside /app/Controllers folder.
Open PostController.php and write this complete code into it.
<?php namespace App\Controllers; use App\Controllers\BaseController; use App\Models\Post; class PostController extends BaseController { public function index() { $postObject = new Post(); $data = [ [ 'title' => 'Custom Title', 'body' => 'Post Body New' ], [ 'title' => 'Custom Title 2', 'body' => 'Post Body New 2' ], [ 'title' => 'Custom Title 3', 'body' => 'Post Body New 3' ], [ 'title' => 'Custom Title 4', 'body' => 'Post Body New 4' ] ]; $postObject->insertBatch($data); } }
Route
Open Routes.php from /app/Config folder. Add this route into it.
//... $routes->get("data", "PostController::index");
URL: http://localhost:8080/data
Output
