To validate a GeoJSON file in Laravel, you can use Laravel's validation feature along with a custom validation rule. Here's how you can do it:

  1. First, create a new custom validation rule by running the following command in your terminal:
1
php artisan make:rule GeoJSONValidationRule


  1. Open the generated GeoJSONValidationRule class located in the app/Rules directory and define the logic for validating GeoJSON data. Here's an example implementation:

<?php

namespace AppRules;

use IlluminateContractsValidationRule;

class GeoJSONValidationRule implements Rule
{
    public function passes($attribute, $value)
    {
        $data = json_decode($value, true);

        // Check if it's a valid GeoJSON format
        // Add your validation logic here

        return true; // return false if validation fails
    }

    public function message()
    {
        return 'The :attribute must be a valid GeoJSON format.';
    }
}


  1. Next, in your controller or wherever you want to perform the validation, use the custom validation rule you created. Here's an example of how you can use it:

use AppRulesGeoJSONValidationRule;
use IlluminateHttpRequest;
use IlluminateSupportFacadesValidator;

public function validateGeoJSON(Request $request)
{
    $validator = Validator::make($request->all(), [
        'geojson_data' => ['required', new GeoJSONValidationRule],
    ]);

    if ($validator->fails()) {
        return response()->json($validator->errors(), 400);
    }

    // Validation passed, continue with your logic
}


  1. Update the geojson_data key in the validation rule with the actual key where your GeoJSON data is present in the request.
  2. With these steps, you can now validate GeoJSON files in your Laravel application using a custom validation rule.
