### Installing Ladder Package - Bash

Source: https://github.com/eneadm/ladder/blob/main/README.md

This command installs the Ladder package into your Laravel project using Composer. It fetches the package from Packagist and adds it to your project's dependencies, requiring Laravel 10 or above.

```Bash
composer require eneadm/ladder
```

--------------------------------

### Installing Ladder Service Provider - Bash

Source: https://github.com/eneadm/ladder/blob/main/README.md

After installing the Ladder package, this Artisan command creates a new `LadderServiceProvider` in your Laravel application. This service provider is essential for managing roles and permissions within the application.

```Bash
php artisan ladder:install
```

### Implementing Authorization Policy with Ladder - PHP

Source: https://github.com/eneadm/ladder/blob/main/README.md

This PHP example shows how to implement an authorization policy method, `update`, using Ladder's `hasPermission` method. It checks if a given user has the required permission (e.g., 'post:update'), which is crucial for controlling access to specific actions within the application.

```PHP
/**
 * Determine whether the user can update a post.
 */
public function update(User $user, Post $post): bool
{
    return $user->hasPermission('post:update');
}
```

### Defining Roles and Permissions with Ladder - PHP

Source: https://github.com/eneadm/ladder/blob/main/README.md

This PHP code demonstrates how to define roles and their associated permissions using the `Ladder::role` method within `App\Providers\LadderServiceProvider`. Each role is defined with a slug, name, an array of permissions, and an optional description, enabling static role management.

```PHP
Ladder::role('admin', 'Administrator', [
    'post:read',
    'post:create',
    'post:update',
    'post:delete',
])->description('Administrator users can perform any action.');

Ladder::role('editor', 'Editor', [
    'post:read',
    'post:create',
    'post:update',
])->description('Editor users have the ability to read, create, and update posts.');
```

--------------------------------

### Running Database Migrations for Ladder - Bash

Source: https://github.com/eneadm/ladder/blob/main/README.md

This Artisan command executes the database migrations provided by the Ladder package. It creates a single `user_role` pivot table, which is used to assign roles to users in the database.

```Bash
php artisan migrate
```

### Assigning Roles to a User - PHP

Source: https://github.com/eneadm/ladder/blob/main/README.md

This PHP snippet illustrates how to assign a role to a user using the `roles` relationship provided by the `Ladder\HasRoles` trait. It finds a user by ID and then uses `updateOrCreate` to assign or update the specified role for that user.

```PHP
use App\Models\User;

$user = User::find(1);

$user->roles()->updateOrCreate(['role' => 'admin']);
```

--------------------------------

### Accessing HasRoles Trait Methods - PHP

Source: https://github.com/eneadm/ladder/blob/main/README.md

This snippet outlines the various methods provided by the `Ladder\HasRoles` trait for managing user roles and permissions. It includes methods for accessing user roles, checking role existence, retrieving role-specific permissions, and checking general user permissions. All method arguments can accept string, array, Collection, or Enum.

```PHP
// Access all of user's roles...
$user->roles : Illuminate\Database\Eloquent\Collection

// Determine if the user has the given role... 
$user->hasRole($role) : bool

// Access all permissions for a given role belonging to the user...
$user->rolePermissions($role) : array

// Access all permissions belonging to the user...
$user->permissions() : Illuminate\Support\Collection

// Determine if the user role has a given permission...
$user->hasRolePermission($role, $permission) : bool

// Determine if the user has a given permission...
$user->hasPermission($permission) : bool
```

--------------------------------

### Integrating HasRoles Trait into User Model - PHP

Source: https://github.com/eneadm/ladder/blob/main/README.md

This PHP snippet demonstrates how to integrate the `HasRoles` trait into your `App\Models\User` model. By using this trait, the User model gains access to methods necessary for managing user roles and permissions within the Ladder package.

```PHP
use Ladder\HasRoles;
 
class User extends Authenticatable
{
    use HasRoles;
}
```
