Model media configuration

Let's assume you configured your model to use the media library like following:

use Spatie\MediaLibrary\Models\Media;

public function registerMediaConversions(Media $media = null)
{
    $this->addMediaConversion('thumb')
        ->width(130)
        ->height(130);
}

public function registerMediaCollections()
{
    $this->addMediaCollection('main')->singleFile();
    $this->addMediaCollection('my_multi_collection');
}

Generic file management

Generic file management

In order to be able to upload and handle generic files just go ahead and use the Files field.

use Ebess\AdvancedNovaMediaLibrary\Fields\Files;

Files::make('Single file', 'one_file'),
Files::make('Multiple files', 'multiple_files')->multiple(),

Single image upload

Single image upload

use Ebess\AdvancedNovaMediaLibrary\Fields\Images;

public function fields(Request $request)
{
    return [
        Images::make('Main image', 'main') // second parameter is the media collection name
            ->thumbnail('thumb') // conversion used to display the image
            ->rules('required'), // validation rules
    ];
}

Multiple image upload

If you enable the multiple upload ability, you can order the images via drag & drop.

Multiple image upload

use Ebess\AdvancedNovaMediaLibrary\Fields\Images;

public function fields(Request $request)
{
    return [
        Images::make('Images', 'my_multi_collection') // second parameter is the media collection name
            ->conversion('medium-size') // conversion used to display the "original" image
            ->conversionOnView('thumb') // conversion used on the model's view
            ->thumbnail('thumb') // conversion used to display the image on the model's index page
            ->multiple() // enable upload of multiple images - also ordering
            ->fullSize() // full size column
            ->rules('required', 'size:3') // validation rules for the collection of images
            // validation rules for the collection of images
            ->singleImageRules('dimensions:min_width=100'),
    ];
}

Names of uploaded images

The default filename of the new uploaded file is the original filename. You can change this with the help of the function setFileName, which takes a callback function as the only param. This callback function has three params: $originalFilename (the original filename like Fotolia 4711.jpg), $extension (file extension like jpg), $model (the current model). Here are just 2 examples of what you can do:

// Set the filename to the MD5 Hash of original filename
Images::make('Image 1', 'img1')
    ->setFileName(function($originalFilename, $extension, $model){
        return md5($originalFilename) . '.' . $extension;
    });

// Set the filename to the model name
Images::make('Image 2', 'img2')
    ->setFileName(function($originalFilename, $extension, $model){
        return str_slug($model->name) . '.' . $extension;
    });

By default, the "name" field on the Media object is set to the original filename without the extension. To change this, you can use the setName function. Like setFileName above, it takes a callback function as the only param. This callback function has two params: $originalFilename and $model.

Images::make('Image 1', 'img1')
    ->setName(function($originalFilename, $model){
        return md5($originalFilename);
    });

Responsive images

If you want to use responsive image functionality from the Spatie MediaLibrary, you can use the withResponsiveImages() function on the model.

Images::make('Image 1', 'img1')
    ->withResponsiveImages();

Custom properties

Custom properties

Images::make('Gallery')
    ->customPropertiesFields([
        Boolean::make('Active'),
        Markdown::make('Description'),
    ]);
    
Files::make('Multiple files', 'multiple_files')->multiple()
    ->customPropertiesFields([
        Boolean::make('Active'),
        Markdown::make('Description'),
    ]);
    
// custom properties without user input
Files::make('Multiple files', 'multiple_files')->multiple()
    ->customProperties([
        'foo' => auth()->user()->foo,
        'bar' => $api->getNeededData(),
    ]);

Media Field (Video)

In order to handle videos with thumbnails you need to use the Media field instead of Images. This way you are able to upload videos as well.

use Ebess\AdvancedNovaMediaLibrary\Fields\Media;

class Category extends Resource
{
    public function fields(Request $request)
    {
        Media::make('Gallery') // media handles videos
            ->thumbnail('thumb')
            ->singleMediaRules('max:5000'); // max 5000kb
    }
}

// ..

class YourModel extends Model implements HasMedia
{
    public function registerMediaConversions(Media $media = null)
    {
        $this->addMediaConversion('thumb')
            ->width(368)
            ->height(232)
            ->extractVideoFrameAtSecond(1);
    }
}
