Description

Enhanced the Form validation system with a wildcard support for complex nested array structures. This enables validation of dynamic data like orders with variable products, user lists with different attributes, and other nested collections.

Real-world Use Cases

// E-commerce orders with variable products
$rules = [
    "orders.*.id" => "numeric",
    "orders.*.products.*.name" => "string",
    "orders.*.products.*.available" => "optional|boolean"
];

// User management with dynamic attributes
$rules = [
    "users.*.profile.*.key" => "string",
    "users.*.permissions.*" => "string"
];

// Categories with nested items and tags
$rules = [
    "categories.*.items.*.tags.*" => "string",
    "categories.*.metadata.*.value" => "optional|string"
];

Summary

• Enhanced wildcard validation system to support complex nested array structures
• Added handling for multiple wildcard levels and deeply nested data
• Improved error reporting with accurate field path tracking
• Added tests
