Validation Rules

This package provides the following validation rules to validate WKT Polygons.

wkt_geo_polygon​

// in your validation class
public function rules(): array
{
    return [
        'boundary' => 'wkt_geo_polygon'
    ]
}

The validation rule checks for the following things:

  • Must have more than 2 points
  • Start and end points must be the same
  • Each point must be a valid coordinate
  • Allows with and without the POLYGON prefix
