⚙️ Installation

Require the package via Composer:

composer require schoolees/laravel-psgc

Quick installation:

php artisan psgc:install --seed
php artisan psgc:install --force --seed # Overwrite previously published package files

By default, the package auto-registers routes at /{PSGC_API_PREFIX} and keeps the same URL shape if you later switch to published routes.

Publishing assets (optional):

# Config
php artisan vendor:publish --tag=psgc-config

# Seeders
php artisan vendor:publish --tag=psgc-seeders

# Routes
php artisan psgc:publish-routes
php artisan psgc:publish-routes --force # Overwrite if re-running

# Resources
php artisan vendor:publish --tag=psgc-resources
php artisan vendor:publish --tag=psgc-resources-classes

Generate PSGC models (optional):

php artisan make:psgc-models
php artisan make:psgc-models --force # Overwrite existing models
php artisan make:psgc-models --softdeletes # Include SoftDeletes trait

Example Request:

# Get all Regions
GET /psgc/regions

# Get Cities in the National Capital Region (NCR)
GET /psgc/cities?region_code=1300000000

# Get the City of Manila
GET /psgc/cities?code=1380600000

# Get Barangays in the City of Manila
GET /psgc/barangays?city_code=1380600000

Example JSON Response:

{
  "code": 200,
  "draw": 1,
  "recordsFiltered": 1,
  "recordsTotal": 1,
  "recordsPerPage": 10,
  "data": [
    {
      "code": "1380600000",
      "name": "City of Manila",
      "province_code": null,
      "region_code": "1300000000"
    }
  ],
  "filters": {
    "code": "1380600000"
  }
}

Filtering and Searching

You can filter results by passing query parameters. Refer to the getSearchable() method on each model for available filterable fields.

Example: Get cities in the National Capital Region (NCR)

GET /psgc/cities?region_code=1300000000

Example: Search for a city by name

GET /psgc/cities?name=Manila

🔍 Searchable Fields

Each model has a getSearchable() method to define searchable columns for filtering via API.

Example for a City model:

public function getSearchable(): array
{
    return [
        'query' => ['code', 'region_code', 'province_code', 'is_city'],
        'query_like' => ['name', 'city_class'],
    ];
}

🧩 Service Layer

The package follows the Service-Controller-Resource pattern for clean, maintainable code.

Example:

$results = $this->cityService->getCities(
    request()->all(),
    request()->input('order_by', 'name'),
    request()->input('sort_by', 'desc'),
    request()->input('limit', 10),
    request()->input('offset', 0)
);

Optional .env overrides

To customize API prefix:

PSGC_API_PREFIX=geo # Will change /psgc/regions to /geo/regions.

Route strategy (important):

Default: package auto-registers routes via service provider.
Published routes are appended to routes/web.php with the configured PSGC prefix and middleware so they keep the same /{prefix}/* URLs.
If you want to use published routes/psgc.php, disable package route registration to avoid duplicates:

// config/psgc.php
'register_package_routes' => false,

Pagination safety override:

// config/psgc.php
'max_limit' => 100, // caps ?limit=...

Response format override:

// config/psgc.php
'response_format' => 'datatable', // or 'pagination'
