There isn’t a single/central validation code for user’s input in Drupal. Each form as it own validations handlers, search for _validate in the Drupal API. In addition, there is some re-usable validation functions such as
valid_url()andvalid_email_address(). Drupal also encourage output sanitization with functions such ast(),check_plain()orfilter_xss(). Drupal discourage bad-practive regarding SQL injection by favoring placeholders in query string, seedb_query().
