The dependsOn is not working in the field inside Flexible

[kennethtomagan]

I want to change the Price field value depends on Product field, sane field is inside Flexible
but dependsOn is not working.

Flexible::make('Order items')
    ->addLayout('Select Products', 'product', [
        Select::make('Product')
            ->options(Product::all()->pluck('name', 'id'))
            ->displayUsingLabels()
            ->searchable(),
        Text::make('Price')
        ->dependsOn(["product"], function (Text $field, NovaRequest $request, FormData $formData) {
                if ($formData->product) {
                    $productId = $formData->product;
                    $product = Product::find($productId);
                    $field->withMeta(['value' => $product->price]);
                }
        }),
    ])
    ->button('Add Product')
    ->fullWidth()
    ->limit(10),

anyone encounters this error? how do you guys solve it?

Anyone found a solution?

[nzmattman]

i have the same issue
i wonder if it may have to do with the nested json when selecting the fields it depends on

[lucasff]

this is the same issue the parent dependsOn and official Nova Repeatable item is suffering.

I also have this issue. Want to have dependant fields inside the Flexible. But it isn't working.

I also have this issue. Want to have dependant fields inside the Flexible. But it isn't working.

Right now, I do it by creating a custom field and put it inside Flexible.
In my custom field I create a JS functionality to get the value of dependents field.

It's a bit complicated so I hope it will be fixed sooner.

@kennethtomagan a snippet would be nice?

I had the same problèm, it was due to fields names that automatically crypted by flexible content in order to always have differente names per content. it was something like ckOi67sYIRR0L6kh__entityId.
My temporary solution is to create middleware that remove the crypted part of the fields names 'ckOi67sYIRR0L6kh__entityId for 'creation-fields and update-fields nova api routes . and create hidden fields same as the fields that dependent of another one in the Nova resource that call my flexible content that really handle the dependency callbacks.
that workes perfectly for me .

`class TransformFlexibleNovaFieldNames
{
/**

public function handle(Request $request, Closure $next): Response

$urlPatterns = [
['prefix' => 'nova-api/pages', 'suffix' => 'creation-fields'],

];

    // Construire des expressions régulières basées sur les modèles d'URL
    $regexPatterns = array_map(function ($pattern) {
        $prefix = preg_quote($pattern['prefix'], '/');
        $suffix = preg_quote($pattern['suffix'], '/');
        // Rendre la partie "/\d+" optionnelle
        return "/^{$prefix}(\/\d+)?\/{$suffix}$/";
    }, $urlPatterns);

    // Vérifier si l'URL correspond à l'un des modèles
    $isMatchingUrl = false;
    foreach ($regexPatterns as $regex) {
        if (preg_match($regex, $request->path())) {
            $isMatchingUrl = true;
            break;
        }
    }


    // Si l'URL correspond à l'un des patterns
    if ($isMatchingUrl && $request->has('field')) {
        $sanitizeFields = function ($fields) {
            $sanitized = [];
            foreach ($fields as $key => $value) {
                if (strpos($key, '__') !== false) {
                    $newKey = substr($key, strpos($key, '__') + 2);
                    $sanitized[$newKey] = $value;
                } else {
                    $sanitized[$key] = $value;
                }
            }
            return $sanitized;
        };

        $field = $request->get('field');

        if (strpos($field, '__') !== false) {
            $newField = substr($field, strpos($field, '__') + 2);
            $request->query->set('field', $newField);
        }

        if ($request->post()) {
            $sanitizedPost = $sanitizeFields($request->post());
            $request->replace($sanitizedPost);
        }
    }
    
    return $next($request);
}

}`

in my flexbile content layout

Boolean::make(__("Sélectionner tous les badges de l'émetteur"), 'is_all_badges') ->hide() ->dependsOn( ['entityId'], function (Select $field, NovaRequest $request, FormData $formData){} ),

In my Nova resource that class my flexbile content

Boolean::make(__("Sélectionner tous les badges de l'émetteur"), 'is_all_badges') ->hideFromIndex() ->hide() ->dependsOn( ['entityId'], function (Boolean $field, NovaRequest $request, FormData $formData){ if($formData->entityId){ $field->hide(); } else { $field->show(); } } ),

@editho512 Works like a charm! Exactly what i was looking for! 🤩🥳

I was looking for a MorphTo solution. Solved it based on your middleware:

Resource:

class BlogResource extends Resource {
  
  public function fields(Request $request): array {
    return [
      Flexible::make('Content', 'content')
        ->addLayout(Content::class)
        ->addLayout(ReadMore::class),
      // This is the placeholder for showing blogs list
      Select::make('Blog', 'blog_id')
        ->hide()
        ->hideFromIndex()
        ->options(fn() => Blog::pluck('title', 'id')->toArray())
        ->searchable()
        ->dependsOn( ['model_type'], function (Select $field, NovaRequest $request, FormData $formData) use ($class){
            if($formData->model_type && $formData->model_type === $class){ $field->show(); } else { $field->hide(); }
        }),
      // This is the placeholder for showing pages list
      Select::make('Page', 'page_id')
        ->hide()
        ->hideFromIndex()
        ->options(fn() => Page::pluck('title', 'id')->toArray())
        ->searchable()
        ->dependsOn( ['model_type'], function (Select $field, NovaRequest $request, FormData $formData) use ($class){
            if($formData->model_type && $formData->model_type === $class){ $field->show(); } else { $field->hide(); }
        });
    ];
  }
}

And then my ReadMore flexible block:

class ReadMore extends Layout {
  public function fields(): array {
    Select::make('Type', 'model_type')
                    ->options([
                        Blog::class       => 'Blog',
                        Page::class        => 'Page'
                    ])
                    ->required(),
    Select::make('Blog', 'blog_id')
                ->hide()
                ->resolveUsing(fn ($resource, $model) => $model->model_id)
                ->fillUsing(function ($request, $model) {
                    if($request->blog_id) {
                        $model->model_id = $request->blog_id;
                    }
                })
                ->dependsOn( ['model_type'], function (Select $field, NovaRequest $request, FormData $formData){}),
    Select::make('Page', 'page_id')
                ->hide()
                ->resolveUsing(fn ($resource, $model) => $model->model_id)
                ->fillUsing(function ($request, $model) {
                    if($request->page_id) {
                        $model->model_id = $request->page_id;
                    }
                })
                ->dependsOn( ['model_type'], function (Select $field, NovaRequest $request, FormData $formData){});
  }
}

It took me a few minutes to understand that pages was the resource, so make sure to replace 'pages' for 'your-own-resources':

  ['prefix' => 'nova-api/your-own-resources', 'suffix' => 'creation-fields'],
  ['prefix' => 'nova-api/your-own-resources', 'suffix' => 'update-fields'],
];

Is this workaround still supported? Im not getting a field parameter in the request.

The regex filter works but the only parameters in the request get are:

editing = "true"
editMode = "update"
viaResource = null
viaResourceId = null
viaRelationship = null

$request->get('field') always returns null and so the middleware does not work for me.

Versions

"php": "^8.2",
"laravel/framework": "^11.9",
"laravel/nova": "^4.35.2",
"laravel/sanctum": "^4.0",
"whitecube/nova-flexible-content": "^1.1"

It would be great to have an officially documented workaround, especially since this issue comes up in multiple discussions. The docs mention that this package "does not have constraints on which fields you are allowed to use," which implies to me that all Nova features should work no different than before.

Awesome package, by the way! 👍🏻
