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.
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 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.
Create Database Table
Next, we need a table. That table will be responsible to store data.
Let’s create a table with some columns.
CREATE TABLE users (
id bigint(20) unsigned NOT NULL AUTO_INCREMENT,
name varchar(255) NOT NULL,
email varchar(255) NOT NULL,
PRIMARY KEY (id),
UNIQUE KEY users_email_unique (email)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Successfully, we have created a table.
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.
Import Test Data into Table
Here we have some MySQL queries, please execute inside your database. It will insert few dummy rows into users table to go with this article.
-- -- Dumping data for table `users` -- INSERT INTO `users` (`id`, `name`, `email`) VALUES (1, 'Dorthy Kohler', 'bosco.jessie@example.net'), (2, 'Dr. Maurice Heller', 'kanderson@example.org'), (3, 'Miss Skyla Cronin II', 'donavon61@example.com'), (4, 'Carey Reilly', 'will.marlee@example.org'), (5, 'Mrs. Ressie Gerhold', 'dedric.hodkiewicz@example.com'), (6, 'Albert Hegmann', 'stark.delphine@example.com'), (7, 'Prof. Mozelle Tromp DVM', 'trantow.nathaniel@example.org'), (8, 'Briana Rippin', 'buddy22@example.com'), (9, 'Dr. Abigayle Wintheiser', 'adriana.muller@example.net'), (10, 'Adolphus Runolfsson', 'emiliano.nitzsche@example.net');
Create Model
Open project into terminal run this command.
$ php spark make:model User
It will create User.php at /app/Models folder.
Open User.php and write this code into it.
<?php namespace App\Models; use CodeIgniter\Model; class User extends Model { protected $DBGroup = 'default'; protected $table = 'users'; protected $primaryKey = 'id'; protected $useAutoIncrement = true; protected $insertID = 0; protected $returnType = 'array'; protected $useSoftDelete = false; protected $protectFields = true; protected $allowedFields = []; // 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 = []; }
Create Controller
Open project into terminal and run this command to create it.
$ php spark make:controller Site
It will create Site.php file inside /app/Controllers folder.
Open Site.php and write this complete code into it.
<?php namespace App\Controllers; use App\Controllers\BaseController; use App\Models\User; class Site extends BaseController { public function loadRecord() { $request = service('request'); $searchData = $request->getGet(); // OR $this->request->getGet(); $search = ""; if (isset($searchData) && isset($searchData['search'])) { $search = $searchData['search']; } // Get data $users = new User(); if ($search == '') { $paginateData = $users->paginate(5); } else { $paginateData = $users->select('*') ->orLike('name', $search) ->orLike('email', $search) ->paginate(5); } $data = [ 'users' => $paginateData, 'pager' => $users->pager, 'search' => $search ]; return view('users', $data); } }
Create Layout File
Create a file with name users.php into /app/Views folder.
Open users.php and write this code into it.
