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
