About Apposite
--------------

[](#about-apposite)

Apposite makes it easy to conditionally apply Laravel validation rules, even when you don't have access to [the validator instance](https://laravel.com/docs/validation#conditionally-adding-rules).

Requirements and installation
-----------------------------

[](#requirements-and-installation)

Apposite supports only the latest major version of [Laravel](https://laravel.com/). See [`composer.json`](composer.json) for the exact version requirements.

Install it using [Composer](https://getcomposer.org/):

```
composer require monooso/apposite
```

Usage
-----

[](#usage)

Apposite provides three [custom Laravel validation rules](https://laravel.com/docs/validation#using-rule-objects):

- [`ApplyWhen`](#apply-when)
- [`ApplyUnless`](#apply-unless)
- [`ApplyMap`](#apply-map)

### `ApplyWhen`

[](#applywhen-)

Use `ApplyWhen` to apply one or more validation rules when a condition is met. For example, validate the `email` field if the `contact_method` is "email".

The `ApplyWhen` constructor expects two arguments:

- A conditional, which determines whether the validation rules are applied. This may be a boolean value, or a closure which returns a boolean.
- The validation rules to apply if the conditional evaluates to `true`. The may be in [any format](https://laravel.com/docs/validation#quick-writing-the-validation-logic) recognised by the Laravel validator.

For example:

```
new ApplyWhen($foo === $bar, 'required|string|min:10');

new ApplyWhen(function () {
    return random_int(1, 10) % 2 === 0;
}, ['required', 'string', 'min:10']);
```

Add the `ApplyWhen` rule to your validation rules array in the normal way.

```
public function store(Request $request)
{
    $rules = [
        'contact_method' => ['required', 'in:email,phone'],
        'email'          => [
            new ApplyWhen($request->contact_method === 'email', ['required', 'email', 'max:255']),
        ],
    ];

    $validated = $this->validate($rules);
}
```

### `ApplyUnless`

[](#applyunless-)

`ApplyUnless` is the opposite of `ApplyWhen`. Use it to apply one or more validation rules when a condition *is not* met.

For example:

```
public function store(Request $request)
{
    $rules = [
        'contact_method' => ['required', 'in:email,phone'],
        'email'          => [
            new ApplyUnless($request->contact_method === 'phone', ['required', 'email', 'max:255']),
        ],
    ];

    $validated = $this->validate($rules);
}
```

Refer to the [`ApplyWhen`](#apply-when) documentation for full usage instructions.

### `ApplyMap`

[](#applymap-)

Use `ApplyMap` when you need to choose between different sets of validation rules. For example, when validating that the chosen `delivery_service` is offered by the chosen `delivery_provider`.

```
public function store(Request $request)
{
    $rules = [
        'delivery_provider' => ['required', 'in:fedex,ups,usps'],
        'delivery_service'  => [
            'required',
            new ApplyMap($request->delivery_provider, [
                'fedex' => 'in:one_day,two_day',
                'ups'   => 'in:overnight,standard',
                'usps'  => 'in:two_day,someday',
            ]),
        ],
    ];

    $validated = $this->validate($rules);
}
```

The `ApplyMap` constructor expects two arguments:

- The "key" value, which determines which rules to apply (if any). For example, "fedex".
- A "map" of keys to validation rules. The validation rules may be in any format recognised by the Laravel validator.

Local development
-----------------

[](#local-development)

Development and testing happen entirely inside [Podman](https://podman.io/) containers, driven by the `./dev` script. You do **not** need to install PHP, Composer, or any project dependencies on your machine.

The `dev` helper script builds a disposable PHP + Composer image for the PHP version you name, mounts your working tree into it, and runs your command. Any changes to `composer.json` and `composer.lock` are written back to your disk so they can be committed.

### Prerequisites

[](#prerequisites)

[Podman](https://podman.io/) 5.x or later.

### Common tasks

[](#common-tasks)

The `dev` script always accepts the target PHP version as the first argument. The first time you run a command with a given PHP version, it builds the image automatically.

CommandPurpose`./dev 8.3`Open a shell on PHP 8.3`./dev 8.3 test`Run the test suite`./dev 8.3 lint`Run Laravel Pint`./dev 8.3 composer install`Install dependencies from the lock file`./dev 8.3 composer update`Re-resolve dependencies (rewrites `composer.lock`)`./dev 8.3 composer outdated`List outdated packages`./dev 8.3 php -v`Run any command in the container`./dev build 8.3`Rebuild the image for a versionRun `./dev --help` for the full reference.

### Upgrading PHP or Laravel

[](#upgrading-php-or-laravel)

1. Create a branch.
2. Edit `composer.json` to widen the relevant constraints, e.g. `"php": "^8.3"` and `"illuminate/support": "^13.0"`.
3. Re-resolve dependencies against the target PHP version:

    ```
    ./dev 8.3 composer update
    ```
4. In the event of a conflict, investigate and iterate:

    ```
    ./dev 8.3 composer why-not laravel/framework 13.0.0
    ./dev 8.3 composer require illuminate/support:"^13.0" --no-update
    ./dev 8.3 composer update
    ```
5. Run the tests and linter:

    ```
    ./dev 8.3 test
    ./dev 8.3 lint
    ```
6. Commit `composer.json` and `composer.lock`.

Each PHP version keeps its own dependency cache, so several versions can be tested side by side (e.g. `./dev 8.2 test`, `./dev 8.3 test`) without interfering with each other.
