License summary

Anyone can use and modify this package in any way they want, including commercially, as long as the commercial use is a) creating implemented wizards and/or b) using the implemented wizards.

Basically, the only condition is that you can't sublicense the package or embed it in a framework unless you do so under the AGPLv3 license (which is incompatible with the Nova framework). More details below.

Installation

Add the package to your project;
```
composer require wdelfuego/nova-wizard
```

Publish the config file;

php artisan vendor:publish --provider="Wdelfuego\NovaWizard\ToolServiceProvider" --tag="config"

Update the config file (in config/nova-wizard.php);

The config file allows you to specify as many wizards as you want, each under their own key.
- Update the class name to whatever class name you want to use for this wizard (we will create the class later)
- Update the uri under which the wizard will be available to your end users
- Optionally, update the window title for this wizard
Here's an example minimal config for an AddUserWizard:
```
use App\Nova\Wizards\AddUserWizard;

return [
    'add-user' => [
        'class' => AddUserWizard::class,
        'uri' => 'wizard/add-user',
        'windowTitle' => 'Add user'
    ]
];
```
The key used for each entry in the config file is the 'wizard key' (here: add-user) and will be required to add the wizard views to your NovaServiceProvider.
Update your NovaServiceProvider;
- Add the following statement to the top of the file:
  
  use Wdelfuego\NovaWizard\NovaWizard;
- Add the wizard tool to the array returned by the tools() method, supplying the wizard key to its constructor:
```
ublic function tools()

return [
	new NovaWizard('add-user')
];
```
- If you manually specify your application menu in the boot() method, add a MenuSection or MenuItem that links to this wizard.
  
  Specify the wizard key so the correct URL can be generated, like this:
```
enuItem::link('Add a user', NovaWizard::pathToWizard('add-user'))
```

Finally, implement the wizard;

Create the class file for your wizard. It can go wherever you want, but /app/Nova/Wizards is a good default location if you have no preference.
Make sure you correctly specify that class for the wizard in config/nova-wizard.php
Implement the class to extend Wdelfuego\NovaWizard\AbstractWizard.

You only need to implement the following three methods:

wizardViewData() : array to define the steps and fields in your wizard, like this:

use Laravel\Nova\Fields;

ublic function wizardViewData() : array {
    return [
        'steps' => [
            [
                'title'  => 'Step 1/2',
                'fields' => [
                    Fields\Text::make(__('Username'), 'username'),
                    Fields\Text::make(__('Text field'), 'myText'),
                    Fields\Textarea::make(__('Longer text'), 'myLongerText')
                        ->help("You can use Help texts on Nova fields like you're used to"),
                    Fields\Number::make(__('Some number'), 'myNumber')
                        ->rules('required')
                        ->withMeta(['value' => 60])
                        ->min(1)
                        ->step(1),
                ],
            ],
            [
                'title'  => 'Step 2/2',
                'fields' => [
                    Fields\Text::make(__('Text field 2'), 'myText2'),
                    Fields\Textarea::make(__('Longer text 2'), 'myLongerText2')
                        ->help("You can use Help texts on Nova fields like you're used to"),
                    Fields\Number::make(__('Some number 2'), 'myNumber2')
                        ->rules('required')
                        ->withMeta(['value' => 60])
                        ->min(1)
                        ->step(1),
                ],
            ],
        ],
    ];

onSubmit($formData, &$context) : bool to specify what to do when valid wizard data is submitted, like this:

ublic function onSubmit($formData, &$context) : bool {
//
// When this method gets called, a valid and complete wizard was submitted.
//
// $formData is an array that contains the data submitted by the user.
//
// $context is an empty array that you can store arbitrary info in;
// it will be passed to the next method so you can use it
// to display specific context info to the user on success.

// Parse submitted wizard data somehow
$user = User::create(['name' => $formData['username']]);
$context['newUserId'] = $user->id;

// Return true at the end of this method to indicate success
return true;

// Or return false if the data can not be parsed successfully;
// the user will then stay in the form view and have a chance
// to revise the data before resubmitting.

successViewData($context) : array to specify what message to show to the user when onSubmit returns true, like this:

ublic function successViewData($context) : array {

return [
	'message' => 'Successfully created user with id: ' .$context['newUserId']
];

Adding more wizards

Repeat step 3 to 5 from the Installation steps above for every wizard you want to add to your Laravel Nova app.

Advanced usage

Using query parameters

As of version 1.1, thanks to a contribution by @olliescase, you can pass query parameters to your wizard URL, that will then be available within the wizard definition so you can customize your wizard or pre-fill certain fields based on the query parameter values.

For example, if you want to use a wizard to do something in the context of a specific Nova resource instance, you could create a Nova Action that returns a parametrized URL:

return $this->redirect('/' . NovaWizard::pathToWizard('my-wizard') . "?parentId={$resource->id}");

Then in the wizard definition you can get the specified parameter value like this:

$this->request->get('parentId')

Or, if you want to use the same wizard definition for two slightly different forms, you could add it to the application menu twice, but differentiate using a query parameter. You can then get the value of that query parameter in the wizard definition using $this->request->get('paramName') so you can customize the wizard fields and how submissions are processed depending on the context.
