Why?
----

[](#why)

If you’ve built more than a couple of Laravel apps, you’ve probably ended up stuffing too much logic into `prepareForValidation()`.

Maybe you’ve written code like this:

```
protected function prepareForValidation(): void
{
    $this->merge([
        'email' => Str::of($this->email)->trim()->lower()->toString(),
        'first_name' => Str::of($this->first_name)->trim()->ucfirst()->toString(),
        'last_name' => Str::of($this->last_name)->trim()->ucfirst()->toString(),
        //...
    ]);
}
```

We've all been there — a quick `trim()` here, a `lower()` there. But soon, `prepareForValidation()` is packed with string cleanup, formatting, and conditionals.

This package solves this.

Installation
------------

[](#installation)

```
composer require jcergolj/request-input-transformer-for-laravel
```

Under the Hood: Pipeline Pattern
--------------------------------

[](#under-the-hood-pipeline-pattern)

This package uses Laravel’s [Pipeline Pattern](https://laravel.com/docs/12.x/helpers#pipeline) under the hood.

That means your modifiers and transformers are run one by one, just like middleware — each one gets the current value (or request), does its thing, and passes it to the next.

Modifiers vs Transformers
-------------------------

[](#modifiers-vs-transformers)

This package gives you two ways to work with request input: **modifiers** and **transformers**.

### 🛠 Modifiers

[](#-modifiers)

Modifiers change values of **existing fields** in the request — great for cleanup and normalization.

```
// Modifying the 'email' field
'email' => [new Trim(), new Lowercase()],
```

Use modifiers when the field already exists and you need to modify only that field .

**Modifiers merges fields automatically inside pipeline `then` method.**

### 🔄 Transformers

[](#-transformers)

Transformers have access to the entire request and can add or change fields based on logic, relationships, or conditions.

```
new AddFullName(),
new RemoveItemIfEmpty(),
```

Use transformers when you need to generate new fields or apply logic that involves more than one input.

Nested Input Support
--------------------

[](#nested-input-support)

This package supports nested input keys — including wildcard syntax — out of the box. You can apply modifiers or transformers to fields like:

```
'members.*.email' => [new Trim()],
```

Usage
-----

[](#usage)

### Step 1: Create a Modifier and Transformer

[](#step-1-create-a-modifier-and-transformer)

#### Modifier: Trim strings

[](#modifier-trim-strings)

```
namespace App\Http\Modifiers;

class Trim
{
    public function handle($value, $next)
    {
        return $next(trim($value));
    }
}
```

#### Transformer: Generate a full name from first and last name
