Installation

Install the package in a Laravel Nova project via Composer and run migrations:

# Install package
composer require optimistdigital/nova-media-field

# And then run migrations
php artisan migrate

And then register the NovaMediaLibrary tool in NovaServiceProvider:

use OptimistDigital\MediaField\NovaMediaLibrary;

public function tools()
{
    return [
        new \OptimistDigital\MediaField\NovaMediaLibrary,
    ];
}

Usage

use OptimistDigital\MediaField\MediaField;

// ...

fields() {
  return [
    MediaField::make('Profile image', 'profile_image'),

    // Configurable options:
    MediaField::make('Config example', 'config_example')
      ->multiple() // Allows multiple images to to be selected
      ->collection('profile-pictures') // Defines a fixed collection of images instead of a global scope
      ->compact($width, $height = null) // Defines the thumbnail image size shown in Nova (to actually change thumbnail image size, use config)
  ]
}

Image thumbnails

Image thumbnails define different conversions for uploaded images. These conversions can be configured under media field config file under image_sizes key.

# config/nova-media-field.php

[
    'image_sizes' => [
        'thumbnail' => [
            'width' => 150,
            'height' => 150,
            'crop' => true
        ],
        'medium' => [
            'width' => 300
        ]
    ],
]
  • crop - Default: false, when true then image might be cropped if not fit for defined ratio. Requires width and height to be defined.
  • width - Width to resize the image
  • height - Height to resize the image

Defining only one dimension (width or height) keeps the ratio.

Video thumbnails

Media field can generate thumbnails from the first frame of the video. It uses ffmpeg and php-ffmpeg to achieve this.

To enable this, you must:

  • Install ffmpeg
  • Provide paths to ffmpeg and ffprobe (on some environments)

If ffmpeg and ffprobe paths are not automatically detected, add these variables to your ENV.

# NB! Including extension (ie .exe on Windows)
FFMPEG_PATH=/usr/local/bin/ffmpeg
FFPROBE_PATH=/usr/local/bin/ffprobe

WebP support

By default WebP support is enabled in nova media config file. On image upload the WebP will be generated automatically for you. If you have activated or plan to activate it later then you can use commands below to regenerate missing thumbnails and WebP files.

Regenerate thumbnails

To regenerate thumbnails (after defining a new thumbnail size etc) run this command:

php artisan media:regenerate-thumbnails

Regenerate WebP files

To regenerate your missing WebP files run this command:

php artisan media:regenerate-webp

Collections

Collections are basically upload groups that can have their own set of upload rules. Collection configuration goes under media field config file under collection key.

# config/nova-media-field.php

[
    'collections' => [
        'banners' => [
            'label' => 'Banners',
            'constraints' => [
                'mimetypes' => [
                    'image/svg+xml',
                    'image/svg'
                ]
            ],
            'image_sizes' => [
                'thumbnail'
            ]
        ]
    ],
]

  • label - Display label for collection
  • constraints - Array of validation rules (like in Request validation)
  • image_sizes - Sizes to generate (overrides default)

Handle duplicate uploads

If resolve_duplicates is set to true then md5 hash of first mb of the original uploaded file will be generated and used to check if any file duplicates are discovered. If there is then it will serve existing media item without saving the new one.

# config/nova-media-field.php

[
    // When enabled tries to find if file already exists and
    // serve that instead of creating a duplicate entry
    'resolve_duplicates' => true,
]

Customizing

This package allows overriding of core logic for any custom needs project may have

# config/nova-media-field.php
[
    // media_handler is core class that handles file uploads, storage and thumbnail generation
    'media_handler' => \OptimistDigital\MediaField\Classes\MediaHandler::class,

    // media_resource is nova resource class for Media
    'media_resource' => \OptimistDigital\MediaField\Media::class,

    // media_model is laravel modal used throughout this package
    'media_model' => \OptimistDigital\MediaField\Models\Media::class,
]
