How to Enable Image Upload Support in CKEditor

CKEditor is a powerful content editor that allows users to create and edit content with ease. One of its most popular features is the ability to upload images directly into the editor. However, did you know that you can also enable image upload support for other file types, such as PDFs? In this article, we'll explore how to do just that using a custom CKEditor module.

The Problem

By default, CKEditor only allows users to upload image files (JPG, PNG, GIF, etc.). If you want to allow users to upload other file types, such as PDFs, you'll need to create a custom CKEditor module. This is because the standard image upload feature in CKEditor doesn't support non-image file types.

The Solution

To enable image upload support for PDFs and other file types, you'll need to create a custom CKEditor module. Here's how:

1. Create a new PHP class: Create a new PHP class that extends the `ProcessWire\CKEditor\Plugin` class. This class will contain the code for your custom CKEditor module.

2. Register the plugin: Register the plugin in the `$modules` array of your ProcessWire configuration file (e.g., `config.php`). You can do this by adding a new entry to the array, like this:

```php

$modules->add('MyCKEditorModule', '\MyCKEditorModule');

```

3. Define the upload handler: In your custom plugin class, define an upload handler that will handle file uploads for your custom module. This can be done by overriding the `uploadHandler` method in your plugin class.

4. Create a new upload command: Create a new upload command that will be responsible for uploading files to your server. You can do this by creating a new method in your plugin class, like this:

```php

public function uploadCommand() {

// Code to handle file uploads goes here

}

```

5. Integrate with CKEditor: Integrate your custom upload command with the CKEditor editor by adding it to the `CKEditor::getCommands()` array.

Example Code

Here's some example code that demonstrates how to create a custom CKEditor module that allows users to upload PDF files:

```php

namespace MyCKEditorModule;

use ProcessWire\CKEditor\Plugin;

class MyCKEditorModule extends Plugin {

public function uploadHandler($file) {

// Handle file uploads here

$uploadPath = __DIR__ . '/uploads/';

$filename = $file->getFilename();

$file->moveTo($uploadPath . $filename);

}

public function uploadCommand() {

// Create a new upload command that will handle PDF uploads

$command = new \ProcessWire\CKEditor\Command\UploadImageCommand();

$command->setHandler($this->uploadHandler);

return $command;

}

```

In this article, we've explored how to enable image upload support for non-image file types in CKEditor using a custom module. By following the steps outlined above, you can create your own custom CKEditor module that allows users to upload PDF files and other file types directly into the editor.
