## WordPress Filter Integration

The class integrates with WordPress comment filters during construction and when combining first/last names:

### Applied Filters

| Filter | Applied To | Purpose |
|--------|-----------|---------|
| `pre_comment_author_name` | Name field | Sanitize and validate author name |
| `pre_comment_author_email` | Email field | Sanitize and validate email |
| `pre_comment_author_url` | URL field | Sanitize and validate URL |

### Filter Pattern

Filters are applied using this pattern:
```php
Contact_Form_Plugin::strip_tags(
    stripslashes(
        apply_filters( $filter, addslashes( $value ) )
    )
);
```

This ensures compatibility with WordPress comment handling while preventing XSS.

## Usage Examples

### Basic Usage
```php
$author = new Feedback_Author(
    'John Doe',
    'john@example.com',
    'https://johndoe.com'
);

echo $author->get_display_name(); // "John Doe"
echo $author->get_email();        // "john@example.com"
```

### With First/Last Name
```php
$author = new Feedback_Author(
    '',  // name
    'john@example.com',
    'https://johndoe.com',
    'John',  // first_name
    'Doe'    // last_name
);

echo $author->get_name(); // "John Doe" (combined and filtered)
```

### Display Name Fallback
```php
// No name provided
$author = new Feedback_Author( '', 'john@example.com' );
echo $author->get_display_name(); // "john@example.com"

// With name
$author = new Feedback_Author( 'John Doe', 'john@example.com' );
echo $author->get_display_name(); // "John Doe"
```
