This package can convert request parameters to internal parameters.

It provides a trait that can be used with Laravel request processing classes and the trait code can do the mapping operation.

Web applications usually process requests sent by browsers on behalf of the Web users for instance after processing forms or clicking links.

Often these forms or links contain parameter values that configure actions to be performed on the server side.

Usually, the names of the parameters passed via forms or links have names that are the same names used in the code of the Web application for instance as database table field names.

Sometimes it is convenient for the Web application to use other names that are more friendly to the users but are different from the parameter names used by the application on the server side.

This may be the case when the request parameters have names in the language of the user and the application parameter names are in English or some other specific language.

When there is this difference of names, there needs to exist a parameter conversion process on the server side. This package provides this kind of parameter conversion.

RequestDataAdapter - Adapter for converting input data from Illuminate\Http\Request

<img alt="Packagist Downloads" src=""> <img alt="Packagist Downloads" src="">

This package provides easy conversion of input keys to your internal keys.

This adapter is perfect for you if for example you do not want to give your internal keys containing typos (but we know that you can?t have this?), or vice versa, translate incorrect keys into the correct form.

:scroll: Installation

The package can be installed via composer:

composer require

:scroll: Usage

To use the adapter, you must connect this trait:

class CommentStoreRequest extends FormRequest
    use RequestDataAdapter;

Then you need to implement the mappingData method (PHPStorm itself will offer you add method stubs)

     * {@inheritDoc}
    public function mappingData(): array
        return [
            'tatle' => 'title',
            'autor' => 'author',
            'files' => [
                'file' => [
                    'document_name' => 'name'
            'additions' => [
                'date' => 'date_time',

Thus, you can already work in the controller with the data set you need:

  "title": "Test packages",
  "author": "Taylor",
  "files": [
      "file": {
        "document_name": "my_photo"
  "additions": {
    "date": "date_time"
