|
||||
```php
|
||||
$validator = new SecurityValidator();
|
||||
$request = $_POST; // User input
|
||||
|
||||
$result = $validator->validateRequest(
|
||||
$request,
|
||||
'care_toggle_restriction',
|
||||
'manage_care_restrictions'
|
||||
);
|
||||
|
||||
if (!$result->isValid()) {
|
||||
wp_send_json_error([
|
||||
'message' => $result->getFirstError(),
|
||||
'security_score' => $result->getSecurityScore()
|
||||
], 403);
|
||||
}
|
||||
|
||||
// Use sanitized data
|
||||
$sanitizedData = $result->getSanitizedData();
|
||||
```
|
||||
|
||||
### **AJAX Integration**
|
||||
```php
|
||||
// In SecurityIntegration.php
|
||||
add_action('wp_ajax_care_toggle_restriction',
|
||||
[$this, 'validateToggleRestriction']
|
||||
);
|
||||
|
||||
public function validateToggleRestriction(): void {
|
||||
// Full 7-layer validation automatically applied
|
||||
// XSS, CSRF, rate limiting, capabilities all checked
|
||||
}
|
||||
```
|
||||
|
||||
### **Custom Capability Checking**
|
||||
```php
|
||||
$capabilityChecker = new CapabilityChecker();
|
||||
|
||||
// Check single capability
|
||||
$result = $capabilityChecker->checkCapability('manage_care_restrictions');
|
||||
|
||||
// Check multiple capabilities (user must have ALL)
|
||||
$result = $capabilityChecker->checkMultipleCapabilities([
|
||||
'manage_care_restrictions',
|
||||
'view_care_reports'
|
||||
]);
|
||||
|
||||
// Check contextual capability
|
||||
$result = $capabilityChecker->checkContextualCapability(
|
||||
'manage_care_restrictions',
|
||||
['restriction_owner' => 123]
