What is the good way of validating a form in Drupal 8 ?

I have a bunch of fields which are supposed to be filled by a positive numeric value (and that's all, no other input types, just positive int).

public function validateForm(array &$form, FormStateInterface $form_state) 
$values = $form_state->getValues();

foreach ($values as $method => $fee) 
 if ($method != 'Free order') 
 if (!is_numeric($fee)

The issue is when using $form_state->getValues() it also returns "submit", "form_token", "form_build", "form_id", "op" which is quite boring as those infos are not needed for performing validation.

So what I did is removing those four unwanted values with :

$values = array_splice($values, count($values) - 5, 5);

But it's really annoying, am I doing something wrong, or is just as it ? Because I think those values are really not necessary in the validation process.

The FormState class has a method for that: FormState::cleanValues(). From its description, it's the method you should use.

This function can be used when a module wants to store all submitted form values, for example, by serializing them into a single database column. In such cases, all internal Form API values and all form button elements should not be contained, and this function allows their removal before the module proceeds to storage. Next to button elements, the following internal values are removed by default.

form_id

form_token

form_build_id

op

You simply call it before getting the submitted values.

public function validateForm(array &$form, FormStateInterface $form_state) {
 $form_state->cleanValues();
 $values = $form_state->getValues();

 foreach ($values as $method => $fee) 
 if ($method != 'Free order')

If you need to add more keys to remove from the submitted values, you could use FormState::setCleanValueKeys(), but keep in mind that:

The array passed to the method needs to contain also the default array keys Drupal would remove

The method alters the array keys that are removed from FormState::cleanValues() for every Drupal form
