If you project uses both Spatie Media Library and Backpack for Laravel, this add-on provides the ability for:
- Backpack fields to easily store uploaded files as media (by using Spatie Media Library);
- Backpack columns to easily retrieve uploaded files as media;
More exactly, it provides the ->withMedia() helper, that will handle the file upload and retrieval using Backpack Uploaders. You'll love how simple it makes uploads!
Install and use spatie/laravel-medialibrary v10. If you haven't already, please make sure you've installed spatie/laravel-medialibrary and followed all installation steps in their docs:
# require the package
composer require "spatie/laravel-medialibrary:^10.0.0"
# prepare the database
# NOTE: Spatie migration does not come with a `down()` method by default, add one now if you need it
php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="migrations"
# run the migration
php artisan migrate
# make sure you have your storage symbolic links created for the default laravel `public` disk
php artisan storage:link
# (optionally) publish the config file
php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="config"
Then prepare your Models to use spatie/laravel-medialibrary, by adding the InteractsWithMedia trait to your model and implement the HasMedia interface like explained on Media Library Documentation.
Just require this package using Composer, that's it:
composer require backpack/medialibrary-uploadersOn any field where you upload a file (eg. upload, upload_multiple, image or dropzone), add withMedia() to your field definition, in order to tell Backpack to store those uploaded files using Spatie's Laravel MediaLibrary. For example:
CRUD::field('avatar')->type('image')->withMedia();
// you can also do that on columns:
CRUD::column('avatar')->type('image')->withMedia();
// and on subfields:
CRUD::field('gallery')
->label('Image Gallery')
->type('repeatable')
->subfields([
[
'name' => 'main_image',
'label' => 'Main Image',
'type' => 'image',
'withMedia' => true,
],
]); Backpack sets up some handy defaults for you when handling the media. But it also provides you a way to customize the bits you need from Spatie Media Library. You can pass a configuration array to ->withMedia([]) or 'withMedia' => [] to override the defaults Backpack has set.
CRUD::field('main_image')
->label('Main Image')
->type('image')
->withMedia([
'collection' => 'my_collection', // default: the spatie config default
'disk' => 'my_disk', // default: the spatie config default
'mediaName' => 'custom_media_name' // default: the field name
]);Inside the same configuration array mentioned above, you can use the whenSaving closure to customize the saving process. This closure will be called in THE MIDDLE of configuring the media collection. So AFTER calling the initializer function, but BEFORE calling toMediaCollection(). Do what you want to the $spatieMedia object, using Spatie's documented methods, then return it back to Backpack to call the termination method. Sounds good?
CRUD::field('main_image')
->label('Main Image')
->type('image')
->withMedia([
'whenSaving' => function($spatieMedia, $backpackMediaObject) {
return $spatieMedia->usingFileName('main_image.jpg')
->withResponsiveImages();
}
]);NOTE: Some methods will be called automatically by Backpack; You shoudn't call them inside the closure used for configuration: toMediaCollection(), setName(), usingName(), setOrder(), toMediaCollectionFromRemote() and toMediaLibrary(). They will throw an error if you manually try to call them in the closure.
You can also have the collection configured in your model as explained in Spatie Documentation, in that case, you just need to pass the collection configuration key. But you are still able to configure all the other options including the whenSaving callback.
// In your Model.php
public function registerMediaCollections(): void
{
$this
->addMediaCollection('product_images')
->useDisk('products');
}
// And in YourCrudController.php
CRUD::field('main_image')
->label('Main Image')
->type('image')
->withMedia([
'collection' => 'product_images', // will pick the collection definition from your model
]);Sometimes you will want to create conversions for your images, like thumbnails etc. In case you want to display some conversions instead of the original image on the field you should define displayConversions => 'conversion_name' or displayConversions => ['higher_priority_conversion', 'second_priority_conversion'].
In the end, if none of the conversions are ready yet (maybe they are still queued), we will display the original file as a fallback.
// In your Model.php
public function registerMediaConversions(): void
{
$this->addMediaConversion('thumb')
->width(368)
->height(232)
->keepOriginalImageFormat()
->nonQueued();
}
// And in YourCrudController.php
CRUD::field('main_image')
->label('Main Image')
->type('image')
->withMedia([
'displayConversions' => 'thumb'
]);
// you can also configure aditional manipulations in the `whenSaving` callback
->withMedia([
'displayConversions' => 'thumb',
'whenSaving' => function($media) {
return $media->withManipulations([
'thumb' => ['orientation' => 90]
]);
}
]);You can normally assign custom properties to your media with ->withCustomProperties([]) as stated in spatie documentation, but please be advise that name, repeatableContainerName and repeatableRow are reserved keywords and Backpack values will always overwrite yours.
'whenSaving' => function($media) {
return $media->withCustomProperties([
'my_property' => 'value',
'name' => 'i_cant_use_this_key'
]);
}
// the saved custom properties will be:
// - [my_property => value, name => main_image, repeatableRow => null, repeatableContainerName => null]`Changes are documented here on Github. Please see the Releases tab.
