Step 1 – Install Codeigniter 4 Application
First of all, you need to ownload the latest version of Codeigniter 4. So, visit this link https://codeigniter.com/download Download Codeigniter 4 app and unzip the setup in your local system xampp/htdocs/ .
Note that, please change the download folder name “demo”.
Step 2 – Basic App Configurations
Now, you need to some basic configuration on the app/config/app.php file, so let’s go to application/config/config.php and open this file on text editor.
Set Base URL like this
public $baseURL = 'http://localhost:8080'; To public $baseURL = 'http://localhost/demo/';
Step 3 – Create Database and Table
Create a table by executing the following SQL query:
CREATE DATABASE demo; CREATE TABLE images ( id int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key', name varchar(100) NOT NULL COMMENT 'Name', type varchar(255) NOT NULL COMMENT 'file type', created_at varchar(20) NOT NULL COMMENT 'Created date', PRIMARY KEY (id) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='demo table' AUTO_INCREMENT=1;
Step 4 – Setup Database Credentials
To connect your codeigniter 4 app to the database. So, visit app/Config/ directory and open Database.php. Then add the databasae details like below into database.php file:
public $default = [ 'DSN' => '', 'hostname' => 'localhost', 'username' => 'test', 'password' => '4Mu99BhzK8dr4vF1', 'database' => 'demo', 'DBDriver' => 'MySQLi', 'DBPrefix' => '', 'pConnect' => false, 'DBDebug' => (ENVIRONMENT !== 'development'), 'cacheOn' => false, 'cacheDir' => '', 'charset' => 'utf8', 'DBCollat' => 'utf8_general_ci', 'swapPre' => '', 'encrypt' => false, 'compress' => false, 'strictOn' => false, 'failover' => [], 'port' => 3306, ];
Step 5 – Create Controller
Create UploadMultipleFiles.php file. So, visit app/Controllers directory and create UploadMultipleFiles.php.Then add the following code into it:
<?php namespace App\Controllers; use CodeIgniter\Controller; class UploadMultipleFiles extends Controller { public function index() { return view('upload_multiple_files'); } function uploadFiles() { helper(['form', 'url']); $database = \Config\Database::connect(); $db = $database->table('users'); $msg = 'Please select a valid files'; if ($this->request->getFileMultiple('images')) { foreach($this->request->getFileMultiple('images') as $file) { $file->move(WRITEPATH . 'uploads'); $data = [ 'name' => $file->getClientName(), 'type' => $file->getClientMimeType() ]; $save = $db->insert($data); $msg = 'Files have been successfully uploaded'; } } return redirect()->to( base_url('/') )->with('msg', $msg); } }
index()
– It renders the multiple images and files uploading form in Codeigniter 4 view.uploadFiles()
– This functions helps in uploading the multiple files and images in database and directory.
Step 6 – Create Views
Create upload_multiple_files.php view file, so visit application/views/ directory and create upload_multiple_files.php file. Then add the following HTML into upload_multiple_files.php file:
<!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> <title>Upload Multiple Files or Images in Codeigniter 4 - laratutorials.com</title> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css"> <style> .container { max-width: 500px; } </style> </head> <body> <div class="container mt-5"> <?php if (session('msg')) : ?> <div class="alert alert-success mt-3"> <?= session('msg') ?> </div> <?php endif ?> <form method="post" action="<?php echo base_url('UploadMultipleFiles/uploadFiles');?>" enctype="multipart/form-data"> <div class="form-group mt-3"> <input type="file" name='images[]' multiple="" class="form-control"> </div> <div class="form-group"> <button type="submit" class="btn btn-danger">Upload</button> </div> </form> </div> </body> </html>
Step 7 – Setup Routes
To define a route, So, visit app/Config/ directory and open Routes.php file. Then add the following routes into it:
$routes->setDefaultController('UploadMultipleFiles'); $routes->get('/', 'UploadMultipleFiles::index');
Note that, the routes will be displaying the multiple image or file upload form and submitting the data in the database on successful form submission.
Step 8 – Start Development server
