How to Enable Image Upload Support in CKEditor 5

CKEditor is a popular content management system used for editing text, images, and other media formats. One of the key features of CKEditor is image upload support, which allows users to easily upload images from their local computer to be inserted into the editor content. In this article, we will explore how to enable image upload support in CKEditor 5.

Creating a Custom Module for Image Upload

To create a custom module for image upload in CKEditor, you can use ProcessWire's module system. ProcessWire provides a comprehensive documentation on creating modules, which can be found at 'ProcessWire Documentation'(https://processwire.com/docs/modules/).

In this example, we will create a simple module that allows users to upload PDF files and insert them into the editor content.

Step 1: Create a New Module

To create a new module, go to your ProcessWire installation directory and navigate to the `wire/modules` folder. Create a new folder for your module and name it something like 'imageupload'.

Step 2: Define the Module

In the `imageupload` folder, create a new file called `imageupload.module.php`. This file will contain the definition of our module.

Here is an example of what the `imageupload.module.php` file might look like:

```php

class ImageUploadModule extends Module {

function initialize() {

// Define the module settings

$this->settings = array(

'title' => 'Image Upload',

'description' => 'Enable image upload support in CKEditor 5'

);

}

function hookProcessPageEditLink($hook) {

// Add a new button to the toolbar for image upload

$button = array(

'name' => 'imageupload',

'label' => 'Upload Image',

'icon' => 'fa-upload',

'callback' => 'imageUploadCallback'

);

$hook->append($button);

}

function imageUploadCallback() {

// Create a file input field for image upload

$input = '';

return $input;

}

```

Step 3: Add the Module to CKEditor

To add our custom module to CKEditor, we need to modify the `ckeditor.config.js` file. This file is located in the `wire/modules/ckeditor` folder.

Here is an example of what the modified `ckeditor.config.js` file might look like:

```javascript

CKEDITOR.editorConfig = function(config) {

config.toolbar = '

{ name: 'basicstyles', items: ' 'Bold', 'Italic' ' },

{ name: 'links', items: ' 'Link', 'Unlink' ' },

{ name: 'imageupload', items: ' 'Upload Image' ' }

};

```

Step 4: Test the Module

Once you have added our custom module to CKEditor, you can test it by going to a page in your ProcessWire installation and clicking on the 'Upload Image' button. This should open a file input field that allows you to upload an image.

That's it! With these steps, you should now have a basic image upload module for CKEditor 5. Of course, this is just a starting point, and you can customize your module further by adding more features and functionality.

In the next article, we will explore how to integrate our custom module with ProcessWire's file manager integration. This will allow us to browse and upload images from our local computer directly into the editor content.

I hope this helps! Let me know if you have any questions or need further assistance.
