Validation & sanitization

Pressundo separates sanitization from validation.

• Sanitization normalizes a value into the canonical storage shape.
• Validation checks required rules, allowed options, ranges, formats, nested child errors and row limits.

$field = pu_email('contact_email', ['required' => true]);
$value = pu_sanitize_field($field, ' hello@example.com ');
$result = pu_validate_field($field, $value);

if (! $result->isValid()) {
    $errors = $result->errors();
}

Never confuse stored sanitization with final HTML escaping. Escape when outputting according to context (esc_html(), esc_attr(), esc_url(), etc.).
