Laravel Nova 4+ Button

A Nova package for rendering buttons on index, detail and lens views.

Use buttons to trigger backend events, navigate Nova routes or visit links.

This package is a continuation of dillingham/nova-button.

Created to be compatible with Nova 4.0+

Requirements

What	Minimum
PHP	>=7.4
Laravel	>=8.0
Nova	>=4.0

Installation

You can install this package by running the following command:

composer require sietse85/nova-button

To publish the config file, run the following command:

php artisan vendor:publish --tag="nova-button-config"

Usage

use Sietse85\NovaButton\Button;

public function fields(Request $request)
{
    return [
        ID::make('ID', 'id')->sortable(),
        Text::make('Name', 'name'),
        Button::make('Notify'),
    ];
}

Confirm

You can require a confirmation for destructive actions:

Button::make('Cancel Account')->confirm('Are you sure?'),
Button::make('Cancel Account')->confirm('Confirmation', 'Are you sure you want to cancel your account?'),
Button::make('Cancel Account')->confirm('Confirmation', 'Are you sure you want to cancel your account?', 'Cancel'),

Reload

You can reload the page after all events have finished.

Button::make('Notify')->reload()

If you click multiple buttons, reloading will wait for all buttons to finish.

If an error occurs, the page will not be reloaded.

Action

You can trigger an action now. No ActionFields can be used. Will trigger for current resource only. Handle will be called immediately.

Button::make('Send mail')->action(SendConfirmationMail::class)

If for some reason the Model for the action is not resolved correctly you can use modelForAction to correct it.

Events

By default, clicking the button will trigger an event via AJAX.

Default event: Sietse85\NovaButton\Events\ButtonClick.

The event will receive the resource model it was triggered from and the key:

$event->resource = model
$event->key = "notify"

You can override the key:

Button::make('Notify', 'notify-some-user')

And also the event:

Button::make('Notify')->event(App\Events\NotifyRequested::class)

You can listen to the event by creating a listener and registering it in your EventServiceProvider.

Texts

Title

You can set the title attribute for the button:

Button::make('Notify')->title('Button title')

Label

You can set the label for the button, which is shown on the detail, create and update views:

Button::make('Notify')->label('Button label')

Index name

You can set the index name for the button, which is shown on the index view as the table header:

Button::make('Notify')->indexName('Actions')

Default is set to the button name. You can also pass null to have no index name.

State

Visibility

You can conditionally show the button:

Button::make('Activate')->visible($this->is_active === false),
Button::make('Deactivate')->visible($this->is_active === true),

Or, if you only want specific users to see the button:

Button::make('Notify')->visible($request->user()->can('notifyUser', $this))

Of course you can also use Nova's builtin methods, like for authorization or to limit visibility to specific views.

If you want to show a button on the create or update views you can simply use Nova's builtin methods:

Button::make('Notify')->showOnCreating()->showOnUpdating()

Disabled

You can disable the button:

Button::make('Notify')->disabled()
Button::make('Notify')->disabled($this->is_complete === false)

Feedback

When using events, you might want to provide visual feedback to the end user. This is especially useful for long running listeners.

Button::make('Notify')
    ->loadingText('Sending...')
    ->successText('Sent!')
    ->errorText('Something went wrong...')

There are 3 events and for each event you can provide the text and style:

Event	Text	Style
`loading`	`->loadingText('Sending...')`	`->loadingStyle('grey-outline')`
`success`	`->successText('Done!')`	`->successStyle('success')`
`error`	`->errorText('Something went wrong...')`	`->errorStyle('danger')`

The defaults are defined in the config file.

Nova routes

You can also choose to navigate to any Nova route:

Button::make('Text')->index(App\Nova\User::class)
Button::make('Text')->detail(App\Nova\User::class, $this->user_id)
Button::make('Text')->create(App\Nova\User::class)
Button::make('Text')->edit(App\Nova\User::class, $this->user_id)
Button::make('Text')->lens(App\Nova\User::class, 'users-without-confirmation')

It's also possible to use a resource's filters:

Button::make('Text')
    ->index(App\Nova\Order::class)
    ->withFilters([
        App\Nova\Filters\UserOrders::class => $this->user_id,
        App\Nova\Filters\OrderStatus::class => 'active',
    ])

Links

You can configure the button to open external links:

Button::make('Text')->link('https://nova.laravel.com')
Button::make('Text')->link('https://nova.laravel.com', '_self')

Classes

The button uses the following classes that you can style to your liking:

.nova-button
.nova-button-{resource-name}
.nova-button-success
.nova-button-error
.nova-button-loading

You can also add more classes to a button:

// One class
Button::make('Notify')->classes(['some-class'])

// Or multiple classes
Button::make('Notify')->classes(['some-class', 'another-class'])

Styles

This package uses tailwind-css classes. The default class used is the link class.

You can define the class the button should use:

Button::make('Delete')->style('danger')

The default available classes are as follows:

Fill	Outline	Link
primary	primary-outline	primary-link
success	success-outline	success-link
warning	warning-outline	warning-link
danger	danger-outline	danger-link
info	info-outline	info-link
grey	grey-outline	grey-link

The passed key refers to one of the classes defined in the config file. You are free to change these classes or add your own.

Examples

Lenses

You can use a button with lenses.

First set up the lens:

<?php

namespace App\Nova\Lenses;

class UsersWithoutConfirmation extends Lens
{
    public static function query(LensRequest $request, $query)
    {
        return $query
            ->select(['users.id', 'users.name'])
            ->whereNull('email_verified_at');
    }

    public function fields(Request $request)
    {
        return [
            ID::make('ID', 'id'),
            Text::make('Name', 'name'),
            Button::make('Mark As Confirmed'),
        ];
    }
}

Next, register a listener for the Sietse85\NovaButton\Events\ButtonClick event in your EventServiceProvider:

<?php

namespace App\Listeners;

use Sietse85\NovaButton\Events\ButtonClick;

class ConfirmUser
{
    public function handle(ButtonClick $event)
    {
        if ($event->key == 'mark-as-confirmed') {
            $event->resource->email_verified_at = now();
            $event->resource->save();
        }
    }
}
