Use

Note This package reuses part of the logic used on the Laravel\Nova\Fields\Trix Field to store and handle files. This means we need to follow some steps that are mentioned on the Laravel Nova docs related to adding the migrations and pruning the files.

1. Define two database tables to store pending and persisted Trix uploads. To do so, create a migration with the following table definitions:

Schema::create('nova_pending_field_attachments', function (Blueprint $table) {
    $table->increments('id');
    $table->string('draft_id')->index();
    $table->string('attachment');
    $table->string('original_name');
    $table->string('disk');
    $table->timestamps();
});

Schema::create('nova_field_attachments', function (Blueprint $table) {
    $table->increments('id');
    $table->string('attachable_type');
    $table->unsignedInteger('attachable_id');
    $table->string('attachment');
    $table->string('disk');
    $table->string('url')->index();
    $table->timestamps();

    $table->index(['attachable_type', 'attachable_id']);
});

Note: latest nova already includes these migrations. If so, you might receive error Table already exists while running migrations. In this case, you might only need to add original_name field in nova_pending_field_attachments:

Schema::table('nova_pending_field_attachments', function (Blueprint $table) {
    $table->string('original_name')->after('attachment');
});

1. In your app/Console/Kernel.php file, you should register a daily job to prune any stale attachments from the pending attachments table and storage. Laravel Nova provides the job implementation needed to accomplish this:

use Laravel\Nova\Trix\PruneStaleAttachments;

$schedule->call(function () {
    (new PruneStaleAttachments)();
})->daily();

1. Add the ImageGalleryField field to your Nova Resource.

2. Consider that the images will be stored in a Spatie\MediaLibrary\MediaCollections\Models\Media collection according to the name passed as the first parameter on the field make method or the second parameter if set. (Dont forget to register a media collection in your model)

3. Use the rules() method to define the rules used for every single image.

4. Use the rulesMessages() method to define custom validation messages for the image rules.

5. Use the help() method if you want to place "help" text inside the Drag & Drop area.

Example

<?php
namespace App\Nova;

use Laravel\Nova\Http\Requests\NovaRequest;
use Laravel\Nova\Resource;
use Ardenthq\ImageGalleryField\ImageGalleryField;

final class ResourceName extends Resource
{
    // ....
    public function fields(NovaRequest $request)
    {
        return [
            // ....
            ImageGalleryField::make('Images')
                ->rules('mimes:jpeg,png,jpg,gif', 'dimensions:min_width=150,min_height=150', 'max:5000')
                ->rulesMessages([
                    'mimes'      => 'You must use a valid jpeg, png, jpg or gif image.',
                    'max'        => 'The image must be less than 5MB.',
                    'dimensions' => 'The image must be at least 150px wide and 150px tall.',
                ])
                ->help('Min size 150 x 150. Max filesize 5MB.')
                // Optional: add this method if you want to show the first image
                // of the gallery on the index page
                ->showOnIndex(),
                // ...
        ];
    }
    // ...
}

Compatibility Branch

Due to changes made to the Trix fields in Nova 4.22, this package does not support lower Nova v4 versions on the main branch. If you want to use this package on an older Nova version, please see the nova-compatibility branch in this repostitory and use that to install the package through composer: composer require ardenthq/nova-image-gallery-field:dev-nova-compatibility

Development

1. Run yarn nova:install and yarn install to install all the necessary dependencies for compiling the view components.
2. Run yarn run dev (or yarn run watch) while making changes to the components in your local environment.
3. If you change the vue components, ensure to compile for production before making a PR.

Compile for production

1. Run yarn nova:install and yarn install to install all the necessary dependencies for compiling the view components.
2. Run yarn run production.
