Install

composer require classic-o/nova-media-library

php artisan vendor:publish --provider="ClassicO\NovaMediaLibrary\ToolServiceProvider"

php artisan migrate

php artisan storage:link

Configuration

See configuration file

Usage

Add tool in app/Providers/NovaServiceProvider.php

public function tools()
{
    return [
        new \ClassicO\NovaMediaLibrary\NovaMediaLibrary()
    ];
}

Add Field to the resource.

use ClassicO\NovaMediaLibrary\MediaLibrary;

class Post extends Resource
{
    ...
     public function fields(Request $request)
        {
            return [
                ...
                MediaLibrary::make('Image'),
                ...
            ];
        }
    ...
}

Customization

By default, this field is used as single file. If you need to use as array of files, add option:

# Display
MediaLibrary::make('Gallery')
            ->array(),

By default this files display automatically, gallery or list as in tool.
You can set in first parameter needed display type:

MediaLibrary::make('Documents')
            ->array('list'),

When you use array, set the casts as array to needed column in model and set type nullable TEXT in database
For single file - nullable INT

If you want to hide files under the accordion, add the following option:

MediaLibrary::make('Gallery')
            ->array()
            ->hidden()

You can limit the selection of files by type (Labels of types from configuration file).

MediaLibrary::make('File')
            ->types(['Audio', 'Video'])

To set preview size of images in fields, add the following option (Label of cropped additional image variation)
By default, the preview size is set in the configuration file.

MediaLibrary::make('File')
            ->preview('thumb')

You can also integrate the Media Field with the Trix editor. You need to set a unique name in the trix option and add an additional attribute with the same name in the Trix field:

MediaLibrary::make('For Trix')
            ->trix('unique_trix_name'),

Trix::make('Content')
    ->withMeta([ 'extraAttributes' => [ 'nml-trix' => 'unique_trix_name' ] ])

For set a custom callback for the Media Field, use the method jsCallback.

• The first parameter set as the name of the JS function callback.
• The second (optional) is an array of advanced options

MediaLibrary::make('JS Callback')
	        ->jsCallback('callbackName', [ 'example' => 'Nova' ]),

Your JavaScript callback should have 2 parameters. The first will be an array of files, second - your options.

window.callbackName = function (array, options) {
  console.log(array, options);
}

When you use JS Callback or Trix option two or more times on one resource, set second parameter of make method to any unique name

MediaLibrary::make('JS Callback', 'js_cb_name_1')
	        ->jsCallback('callbackName', [ 'example' => 'Nova' ]),
MediaLibrary::make('Trix Field', 'trix_name_1')
	        ->trix('unique_trix_name'),

Upload by url or path

Also you can programmatically add files to the media library by url or path.

use \ClassicO\NovaMediaLibrary\API;

$result = API::upload('https://pay.google.com/about/static/images/social/og_image.jpg');

If upload done successfully, function return instance of model.
If an error occurred while loading, function will throw exception.

Exceptions (code => text):
0 - The file was not downloaded for unknown reasons
1 - Forbidden file format
2 - File size limit exceeded

Get files by ids

In your model stores only id of file(s). To get files, use the API class method:

$files = API::getFiles($ids, $imgSize = null, $object = false);

# First parameter - id or array of ids
# Second - if you want to get images by size variation, write label of size
# Third - by default function return array of urls. If you want to get full data of files - set true (returns object / array of objects)

Private files

When you use local storage or s3 (with private visibility), you can't get files by url.
To get file, you need to create a GET Route with the name nml-private-file with parameter id and optional img_size. In controller add validation user access.
If access is allowed, you can get file by API method:

... Verifying access

$file = API::getFiles($id, null, true);
return API::getPrivateFile($file->path, request('img_size'))

Localization

To translate this tool another language, you need to add the translation file /resources/lang/vendor/nova-media-library/{lang}.json by adding phrases from en.json
