How to do CKEditor 5 Image Uploading?

Question

ClassicEditor
    .create( editorElement, {
        ckfinder: {
            uploadUrl: 'my_server_url'
        }
    } )
    .then( ... )
    .catch( ... );

What should be my server response? I am using Java in the backend. Whatever my response is, it throws a dialog box 'cannot upload file'.

Answer 1

You can configure CKEditor to upload files

ClassicEditor.create( document.querySelector( '#editor' ), {

    cloudServices: {

        tokenUrl: 'https://example.com/cs-token-endpoint',

        uploadUrl: 'https://your-organization-id.cke-cs.com/easyimage/upload/'

    }

} )

.then( ... )

.catch( ... );

Answer 2

this is my code for Ckeditor 5 and Phalcon framework.#products_desc point to textarea id.

<script>

var myEditor;

ClassicEditor
.create( document.querySelector( '#products_desc' ) ,
{
    ckfinder: {
        uploadUrl: 'Ckfinder/upload'
    }
}
)
.then( editor => {
    console.log( 'Editor was initialized', editor );
    myEditor = editor;
} )
.catch( err => {
    console.error( err.stack );
} );</script>

and my php controller:

 <?php
 use Phalcon\Mvc\Controller;

 class CkfinderController extends Controller
 {

    public function uploadAction()
  {

   try {
    if ($this->request->hasFiles() == true) {
        $errors = []; // Store all foreseen and unforseen errors here
        $fileExtensions = ['jpeg','jpg','png','gif','svg'];
        $uploadDirectory = "../public/Uploads/";
        $Y=date("Y");
        $M=date("m");
           foreach ($this->request->getUploadedFiles() as $file) {
        if (in_array($file->getExtension(),$fileExtensions)) {
           if($file->getSize()<2000000) 
           {

            if (!file_exists($uploadDirectory.$Y)) {
                mkdir($uploadDirectory.$Y, 0777, true);
            }
            if (!file_exists($uploadDirectory.$Y.'/'.$M)) {
                mkdir($uploadDirectory.$Y.'/'.$M, 0777, true);
            }
            $namenew=md5($file->getName().time()).'.'.$file->getExtension();
            $uploadDirectory .=$Y.'/'.$M.'/'; 
            $file->moveTo($uploadDirectory.$namenew);
           }
           else{
            $errors[] = "This file is more than 2MB. Sorry, it has to be less than or equal to 2MB";
           }
        }
        else{$errors[] = "This file extension is not allowed. Please upload a JPEG ,svg,gif,,jpg,PNG file";}

    if(empty($errors))
    {   
       echo '{
        "uploaded": true,
        "url": "http://localhost/cms/public/Uploads/'.$Y.'/'.$M.'/'.$namenew.'"}';
    }
    else{
        echo '{
        "uploaded": false,
        "error": {
            "message": "could not upload this image1"
        }';}
    }
}
else{
    echo '{
    "uploaded": false,
    "error": {
        "message": "could not upload this image1"
    }';}
}
catch (\Exception $e) {
       echo '{
        "uploaded": false,
        "error": {
            "message": "could not upload this image0"
        }';
   }
  }

 }
 ?>

Answer 3

The ckfinder.uploadUrl property configures the CKFinderUploadAdapter plugin. This plugin is responsible for communication with the CKFinder's server-side connector.

So, in other words, your server should run the CKFinder's server-side connector. This is a proprietary software, so I won't go deeper into how it works.

Success response :

{
    "uploaded": true,
    "url": "http://127.0.0.1/uploaded-image.jpeg"
}

Failure response :

{
    "uploaded": false,
    "error": {
        "message": "could not upload this image"
    }
}

class UploadAdapter {
  constructor( loader ) {
    this.loader = loader;
  }

  upload() {
    const data = new FormData();
    data.append('typeOption', 'upload_image');
    data.append('file', this.loader.file);

    return new Promise((resolve, reject) => {
      axios({
        url: `${API}forums`,
        method: 'post',
        data,
        headers: {
          'Authorization': tokenCopyPaste()
        },
        withCredentials: true
      }).then(res => {
        console.log(res)
        var resData = res.data;
        resData.default = resData.url;
        resolve(resData);
      }).catch(error => {
        console.log(error)
        reject(error)
      });
    });
  }

  abort() {
    // Reject promise returned from upload() method.
  }
}
