Check for at least one field using CakePHP 3 check

Question

I am trying to write a validation rule in CakePHP 3 that checks to see if a first name, last name or company name is given.

validators:

$validator
    ->add('prename', 'custom', [
        'rule' => [$this, 'validateName'],
        'message' => __('Prename and lastname OR company name must be set.')
    ]);

$validator
    ->add('lastname', 'custom', [
        'rule' => [$this, 'validateName'],
        'message' => __('Prename and lastname OR company name must be set.')
    ]);

$validator
    ->add('name', 'custom', [
        'rule' => [$this, 'validateName'],
        'message' => __('Prename and lastname OR company name must be set.')
    ]);

Rule Definition:

public function validateName($check, array $context)
{
    if((!empty($context['data']['prename']) && !empty($context['data']['lastname'])) || !empty($context['data']['name'])){
        return true;
    } else {
        return false;
    }
}

But the check does not behave as expected. If I enter the company name, I will receive validation errors for the first and last name, indicating that the fields are required. The same thing, when I enter the name and surname, he says that the name of the company is required.

What am I doing wrong?

    $validator->notEmpty('name', __("Required when prename and lastname is empty."), function ($context) {
        return !$context['data']['prename'] && !$context['data']['lastname'];

, , :

$validator
    ->add('various_fee_text', 'custom', [
        'rule' => [$this, 'variousFieldsChecker'],
        'message' => __('Udfyld både Tekst og DKK feltet'),
    ])
    ->allowEmpty('various_fee_text');

Vaildation:

/**
 * Method checks whether or not various fee text and various fee prices are either both empty, both set or "dirt",
 * meaning only one of them is set and the other is empty. We want either both to be set or both to be empty.
 *
 * @return bool depending on it OK or not
 */
public function variousFieldsChecker($value, $context)
{
    $varioustext = $context['data']['various_fee_text'];
    $variousPrice = $context['data']['various_fee_price'];

    if (!empty($varioustext) && !empty($variousPrice)) {
        return true;
    } elseif ((empty($varioustext) && empty($variousPrice))) {
        return true;
    }

    return false;
}

To do this, CakePhp provides the creation of custom validation. You need to create two authentication functions in your model class and conditionally call them a controller function. You can create a check function as

    public function validationName($validator){

       $validator
       ->requirePresence('prename')
       ->notEmpty('prename', 'Prename must be set.')

       ->requirePresence('lastname')
       ->notEmpty('lastname', 'Lastname must be set.')

       ->allowEmpty('name');

       return $validator;
   }



public function validationCompany($validator){

       $validator
       ->requirePresence('name')
       ->notEmpty('name', 'Company name must be set.')

       ->allowEmpty('prename')
       ->allowEmpty('lastname');

       return $validator;
   }

In the controller, you can call these functions conditionally, like

$validator = 'company';
if(empty($this->request->data[''])){
  $validator = 'name';
}
$entity = $this->{$this->modelClass}->newEntity();
$entitydata = $this->{$this->modelClass}->patchEntity($entity, $this->request->data, ['validate' => $validator]);

$this->{$this->modelClass}->save($entitydata);

You need to break through the table name, or check the input identifier in the html view part.
