What is a Kropify?

A Kropify is a tool that can be integrated into CodeIgniter framework projects for the purpose of giving users easy way to crop their profile pictures and cover images. It uses JQuery 3.x library in it's functionality as dependency. That's why it is important to include JQuery library on current view file.

Requirements

PHP >= 7.2
Composer is required
CodeIgniter 4.x
JQuery 3.x

After Kropify package updated, you need also to update its assets (css and js minified files) by running the following command in terminal:

 php spark publish:kropify-assets

Usage

For Kropify Js file, you need to call the following helper function inside <body> tag but before closing </body> tag after including JQuery as shown in below example.

  ..........
   .....
   <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.7.1/jquery.min.js"></script>
   <?= kropifyScripts() ?>
 </body>
</html>

In controller

To include Kropify class in controller is very simple. Just import the following lines on your controller.

 use Mberecall\CodeIgniter\Library\Kropify;

To upload the cropped image you will use the following lines inside method:

$request = \Config\Services::request();

 // Define path of image destination
 $path = 'images/users/';

//if you did not define name attribute on input file tag, the default name attribute value is "image". eg: $file = $request->file('image');
 $file = $request->file('avatar'); 

//Upload cropped image examples
 $upload = Kropify::getFile($file)->save($path); //This will give us random image name "5678cKs374hxdu5438vhsk83.png"
 $upload = Kropify::getFile($file,'avatar')->save($path); //This will geive us image name "avatar.png"
 $upload = Kropify::getFile($file,'avatar.jpg')->save($path); //This will geive us image name "avatar.jpg"
 $upload = Kropify::getFile($file,'avatar.dng')->save($path); //When you make a mistake on extension. This will give us image name "avatar.dng.png"
 $upload = Kropify::getFile($file,'avatar.png')->maxWoH(411)->save($path); //This will resize cropped image width or height to `411`

 //Return json
 $this->response->setJSON(['status'=>"OK",'message'=>'Your profile picture has been.']);

 echo json_encode(['status'=>"OK",'message'=>'Your profile picture has been.']);

The above lines will upload the cropped image in the specified path. The cropped image will be uploaded in CodeIgniter public folder Very important function on the chain is maxWoH(). This function will limit maximum dimensions (Width or Height) in px value of the uploaded image. If you do not need to compress and resize the cropped image, just do not add maxWoH() to the Kropify upload function chain.

Get Cropped/Uploaded image details

When cropped image uploaded successfully, you can get the uploaded image information like name, size, width and height. You can use these details when you need to store them into database. Below are examples of getting uploaded image details:

$request = \Config\Services::request();
$path = 'images/users/';
$file = $request->file('avatar');
$upload = Kropify::getFile($file,'avatar.png')->maxWoH(710)->save($path);

//Get All details
$infos = Kropify::getInfo(); //option 1 
$infos = $upload->getInfo(); //option 2 

//According to the above options, you can get individual image info as follow:
$image_name = $infos->getName; // IMG_XH56.jpg
$image_size = $infos->getSize; // 13094
$image_width = $infos->getWidth; // 710
$image_height = $infos->getHeight; // 710

//You can also get individual image name, size, width and height after image uploaded without first getting all info as follow:

$image_name = $upload->getName(); //option 1
$image_name = Kropify::getName(); //option 2

$image_size = $upload->getSize(); //option 1
$image_size = Kropify::getSize(); //option 2

$image_width = $upload->getWidth(); //option 1
$image_width = Kropify::getWidth(); //option 2

$image_height = $upload->getHeigth(); //option 1
$image_height = Kropify::getHeigth(); //option 2


/**
 * According to the above guidance, use the following examples 
 * to save cropped image data into database.
 */

 $student = new Student();
 $student->insert([
   'name'=>'John Doe',
   'picture'=>$infos->getName, //IMG_USER_982.jpg
 ]);

 //Return json data
 return $this->response->setJSON([
         'status'=>"OK",
         'message'=>'Your profile picture has been successfully updated.',
         'imageInfo'=>$infos
      ]);
