Step 3: Create a Database in table
In this step, We will create the database and table.
1 2 3 4 5 | CREATE TABLE IF NOT EXISTS `students` ( `id` int(11) NOT NULL AUTO_INCREMENT, `image` varchar(164) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=15 ; |
Step 4: Connect to Database
Go to the “app/Config/Database.php” folder and open the database.php file some changes in this file like hostname, database username, database password, and database name.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | public $default = [ 'DSN' => '', 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'codeigniter4_demo', 'DBDriver' => 'MySQLi', 'DBPrefix' => '', 'pConnect' => false, 'DBDebug' => (ENVIRONMENT !== 'production'), 'cacheOn' => false, 'cacheDir' => '', 'charset' => 'utf8', 'DBCollat' => 'utf8_general_ci', 'swapPre' => '', 'encrypt' => false, 'compress' => false, 'strictOn' => false, 'failover' => [], 'port' => 3306, ]; |
Step 5: Create Controller and Model
In this step, we will create the “Student.php” controller and the “StudentModel.php” model.
app/Controllers/Student.php
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 | <?php namespace App\Controllers; use CodeIgniter\Controller; use App\Models\StudentModel; class Student extends Controller { public function __construct() { helper(['form', 'url']); } public function index() { return view('add'); } public function store() { $data = $_POST['image']; if(!empty($data)){ $img_arr_a = explode(";", $data); $img_arr_b = explode(",", $img_arr_a[1]); $data = base64_decode($img_arr_b[1]); $image_name = time() . '.png'; $path = WRITEPATH . 'uploads/'. $image_name; file_put_contents($path, $data); $saveData = [ 'image' => $image_name, ]; $model = new StudentModel(); $save = $model->insert($saveData); return json_encode(['status' => 1, 'message' => "Image uploaded successfully"]); } } } ?> |
app/Models/StudentModel.php
1 2 3 4 5 6 7 8 9 10 11 12 | <?php namespace App\Models; use CodeIgniter\Database\ConnectionInterface; use CodeIgniter\Model; class StudentModel extends Model { protected $table = 'Students'; protected $allowedFields = ['image']; } ?> |
Step 6: Create Views Files
Finally, we will create the add.php in the app/views directory.
app/views/add.php
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 | <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>CodeIgniter 4 Crop Image Example Using Croppie.js - XpertPhp</title> <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css"> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/croppie/2.6.5/croppie.css" /> </head> <body> <div class="container mt-4"> <input type="file" name="file" id="img-crop" accept="image/*" /> </div> <div id="imageModel" class="modal fade bd-example-modal-lg" role="dialog"> <div class="modal-dialog modal-lg"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title">Crop and Resize Image</h4> </div> <div class="modal-body"> <div id="previewImage" style="width:400px;"></div> <button class="btn btn-primary btn-block crop_my_image">Store</button> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">Close</button> </div> </div> </div> </div> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/croppie/2.6.5/croppie.min.js"></script> <script> $(document).ready(function () { $image_crop = $('#previewImage').croppie({ enableExif: true, viewport: { width: 220, height: 220, type: 'circle' // square }, boundary: { width: 320, height: 320 } }); $('#img-crop').on('change', function () { var reader = new FileReader(); reader.onload = function (event) { $image_crop.croppie('bind', { url: event.target.result }).then(function () { }); } reader.readAsDataURL(this.files[0]); $('#imageModel').modal('show'); }); $('.crop_my_image').click(function (event) { $image_crop.croppie('result', { type: 'canvas', size: 'viewport' }).then(function (response) { $.ajax({ type: 'post', url: "<?php echo site_url('student/store'); ?>", data: { "image": response }, success: function (data) { console.log(data); $('#imageModel').modal('hide'); } }) }); }); }); </script> </body> </html> |
Step 7: Run The Application
We can start the server and run the codeigniter 4 application using the below command.
1 | php spark serve |
Now we will run our example using the below Url in the browser.
1 | http://localhost:8080/student |
