public FormValidator::executeValidateHandlers(&$form, FormStateInterface &$form_state)
Executes custom validation handlers for a given form.
Button-specific handlers are checked first. If none exist, the function falls back to form-level handlers.
Parameters
$form: An associative array containing the structure of the form.
$form_state: The current state of the form. If the user submitted the form by clicking a button with custom handler functions defined, those handlers will be stored here.
