Nova Froala Field

Froala WYSIWYG Editor field for Laravel Nova

Introduction

This is a fork of the original froala/nova-froala-field repository. The original is no longer maintained. I created this fork because our company needs a working version of Froala in Nova. This fork contains an updated version of Froala (v4) without 3rd party plugin support (you can read here why).

Upgrading from v3 to v4

This version has some new minimum requirements:

PHP ^8.0
laravel/framework ^9.0
laravel/nova ^3.0
league/flysystem ^3.0 (default with Laravel 9)

You may replace "froala/nova-froala-field": "^3.x" with "pathfindermediagroup/nova-froala-field": "^4.0" in your composer.json if you were using the old version from Froala. Just make sure to force publish the new assets like so:

php artisan vendor:publish --tag=froala-styles --provider=Froala\\NovaFroalaField\\FroalaFieldServiceProvider --force

You may also remove the public/vendor/nova/froala folder from your project, as it is no longer needed or supported.

Froala WYSIWYG Editor Field

Full support of attaching Images, Files and Videos

Form Field

Notifications for Froala events are handled by Toasted which is provided in Nova by default.

Installation

You can install the package into a Laravel application that uses Nova via composer:

composer require pathfindermediagroup/nova-froala-field

Usage

Just use the Froala\NovaFroalaField\Froala field in your Nova resource:

namespace App\Nova;

use Froala\NovaFroalaField\Froala;

class Article extends Resource
{
    // ...

    public function fields(Request $request)
    {
        return [
            // ...

            Froala::make('Content'),

            // ...
        ];
    }
}

Override Config Values

To change any of config values for froala field, publish a config file:

php artisan vendor:publish --tag=config --provider=Froala\\NovaFroalaField\\FroalaFieldServiceProvider

Customize Editor Options

For changing any Available Froala Option edit nova.froala-field.options value:

/*
|--------------------------------------------------------------------------
| Default Editor Options
|--------------------------------------------------------------------------
|
| Setup default values for any Froala editor option.
|
| To view a list of all available options check out the Froala documentation
| {@link https://www.froala.com/wysiwyg-editor/docs/options}
|
*/

'options' => [
    'toolbarButtons' => [
        [
            'bold',
            'italic',
            'underline',
        ],
        [
            'formatOL',
            'formatUL',
        ],
        [
            'insertImage',
            'insertFile',
            'insertLink',
            'insertVideo',
        ],
        [
            'html',
        ],
    ],
],

//...

If you want to set options only to specific field, just pass them to options method:

public function fields(Request $request)
{
    return [
        // ...

        Froala::make('Content')->options([
            'editorClass' => 'custom-class',
            'height' => 300,
        ]),

        // ...
    ];
}

Attachments

Nova Froala Field provides native attachments driver which works similar to Trix File Uploads, but with ability to optimize images and preserve file names. Also you have an ability to switch to the trix driver to use its upload system.

It's Recommended to use froala driver (enabled by default) to be able to use current and future additional features for attachments, provided by Froala.

Froala Driver

To use froala driver, publish and run a migration:

php artisan vendor:publish --tag=migrations --provider=Froala\\NovaFroalaField\\FroalaFieldServiceProvider 
php artisan migrate

Trix Driver

If previously you have used Trix attachments and you want to preserve behavior with same tables and handlers you can use trix driver in config file:

/*
|--------------------------------------------------------------------------
| Editor Attachments Driver
|--------------------------------------------------------------------------
|
| If you have used `Trix` previously and want to save the same flow with
| `Trix` attachments handlers and database tables you can use
| "trix" driver.
|
| *** Note that "trix" driver doesn't support image optimization
| and file names preservation.
|
| It is recommended to use "froala" driver to be able to automatically
| optimize uploaded images and preserve attachments file names.
|
| Supported: "froala", "trix"
|
*/

'attachments_driver' => 'trix'

//...

Attachments Usage

To allow users to upload images, files and videos, just like with Trix field, chain the withFiles method onto the field's definition. When calling the withFiles method, you should pass the name of the filesystem disk that photos should be stored on:

use Froala\NovaFroalaField\Froala;

Froala::make('Content')->withFiles('public');

And also, 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:

use Froala\NovaFroalaField\Jobs\PruneStaleAttachments;


/**
* Define the application's command schedule.
*
* @param  \Illuminate\Console\Scheduling\Schedule  $schedule
* @return void
*/
protected function schedule(Schedule $schedule)
{
    $schedule->call(function () {
        (new PruneStaleAttachments)();
    })->daily();
}

Filenames Preservation

A unique ID is generated by default to serve as the file name according to store method specification. If you want to preserve original client filenames for uploaded attachments, change preserve_file_names option in config file to true.

/*
|--------------------------------------------------------------------------
| Preserve Attachments File Name
|--------------------------------------------------------------------------
|
| Ability to preserve client original file name for uploaded
| image, file or video.
|
*/

'preserve_file_names' => true,

//...

Images Optimization

All uploaded images will be optimized by default by spatie/image-optimizer.

You can disable image optimization in config file:

/*
|--------------------------------------------------------------------------
| Automatically Images Optimization
|--------------------------------------------------------------------------
|
| Optimize all uploaded images by default.
|
*/

'optimize_images' => false,

//...

Or set custom optimization options for any optimizer:

/*
|--------------------------------------------------------------------------
| Image Optimizers Setup
|--------------------------------------------------------------------------
|
| These are the optimizers that will be used by default.
| You can setup custom parameters for each optimizer.
|
*/

'image_optimizers' => [
    Spatie\ImageOptimizer\Optimizers\Jpegoptim::class => [
        '-m85', // this will store the image with 85% quality. This setting seems to satisfy Google's Pagespeed compression rules
        '--strip-all', // this strips out all text information such as comments and EXIF data
        '--all-progressive', // this will make sure the resulting image is a progressive one
    ],
    Spatie\ImageOptimizer\Optimizers\Pngquant::class => [
        '--force', // required parameter for this package
    ],
    Spatie\ImageOptimizer\Optimizers\Optipng::class => [
        '-i0', // this will result in a non-interlaced, progressive scanned image
        '-o2', // this set the optimization level to two (multiple IDAT compression trials)
        '-quiet', // required parameter for this package
    ],
    Spatie\ImageOptimizer\Optimizers\Svgo::class => [
        '--disable=cleanupIDs', // disabling because it is known to cause troubles
    ],
    Spatie\ImageOptimizer\Optimizers\Gifsicle::class => [
        '-b', // required parameter for this package
        '-O3', // this produces the slowest but best results
    ],
],

Image optimization currently supported only for local filesystems

Upload Max Filesize

You can set max upload filesize for attachments. If set to null, max upload filesize equals to php.ini upload_max_filesize directive value.

/*
|--------------------------------------------------------------------------
| Maximum Possible Size for Uploaded Files
|--------------------------------------------------------------------------
|
| Customize max upload filesize for uploaded attachments.
| By default it is set to "null", it means that default value is
| retrieved from `upload_max_size` directive of php.ini file.
|
| Format is the same as for `uploaded_max_size` directive.
| Check out FAQ page, to get more detail description.
| {@link http://php.net/manual/en/faq.using.php#faq.using.shorthandbytes}
|
*/

'upload_max_filesize' => null,

//...

Display Edited Content

According to Froala Display Edited Content documentation you should publish Froala styles:

php artisan vendor:publish --tag=froala-styles --provider=Froala\\NovaFroalaField\\FroalaFieldServiceProvider

include into view where an edited content is shown:

<!-- CSS rules for styling the element inside the editor such as p, h1, h2, etc. -->
<link href="{{ asset('css/vendor/froala_styles.min.css') }}" rel="stylesheet" type="text/css" />

Also, you should make sure that you put the edited content inside an element that has the .fr-view class:

<div class="fr-view">
    {!! $article->content !!}
</div>

Show on Index Page

You have an ability to show field content on resource index page in popup window:

use Froala/NovaFroalaField/Froala;

Froala::make('Content')->showOnIndex();

Just click Show Content

Index Field

License Key

To setup your license key, uncomment key option in the config file and set FROALA_KEY environment variable

// ...
'options' => [
    'key' => env('FROALA_KEY'),
    // ...
],

3rd Party Integrations

I decided to remove 3rd party integrations like embedly and Tui. The reason for this being is that I wanted an updated version of Froala in Nova. I could not get it to work properly with the 3rd party integrations. I do not use them, and thus I am not inclined to spend more time on trying to get them to work. If you know how to do this, feel free to create a pull request.

Advanced

Custom Event Handlers

If you want to setup custom event handlers for froala editor instance, create js file and assign events property to window.froala:

window.froala = {
    events: {
        'image.error': (error, response) => {},
        'imageManager.error': (error, response) => {},
        'file.error': (error, response) => {},
    }
};

to all callbacks provided in window.froala.events, the context of VueJS form field component is automatically applied, you can work with this inside callbacks like with Vue instance component.

After that, load the js file into Nova scripts in NovaServiceProvider::boot method:

public function boot()
{
    parent::boot();

    Nova::serving(function (ServingNova $event) {
        Nova::script('froala-event-handlers', public_path('path/to/js/file.js'));
    });
}

Customize Attachment Handlers

You can change any of attachment handlers by passing a callable:

use App\Nova\Handlers\{
    StorePendingAttachment,
    DetachAttachment,
    DeleteAttachments,
    DiscardPendingAttachments,
    AttachedImagesList
};

Froala::make('Content')
    ->attach(new StorePendingAttachment)
    ->detach(new DetachAttachment)
    ->delete(new DeleteAttachments)
    ->discard(new DiscardPendingAttachments)
    ->images(new AttachedImagesList)
