How to get Attribute and Error Message on Specific Field YII2 in JSON

Question

Validation Rule :

public function rules()
{
   return [
      [['name', 'email', 'password'], 'required'],
      [['email'], 'unique'],
      [['password'],'string', 'min' => 6],
   ];
}

Scenario

public function signup() {
   if (!$this->validate(array('name')) {
      $register_errors['field'] = 'name';
      $register_errors['message'] = $this->getErrors('name');
   }

   if (!$this->validate(array('email')) {
      $register_errors['field'] = 'email';
      $register_errors['message'] = $this->getErrors('email');
   }

   if (!$this->validate(array('password')) {
      $register_errors['field'] = 'password';
      $register_errors['message'] = $this->getErrors('password');
   }
}

Return value

if (!$this->validate) {
   $register_errors['error'] = true;
   return json_encode($register_errors);
}

Result : always return

{"field":["Email cannot be blank."],"message":[],"error":true}

How to properly return all field, error, and message of every field in JSON?

Thanks

You assign the result always to the same index so you get only the last message
Try concat the message usinng .=

public function signup() {
   if (!$this->validate(array('name')) {
      $register_errors['field'] = 'name';
      $register_errors['message'] = $this->getErrors('name');
   }

   if (!$this->validate(array('email')) {
      $register_errors['field'] = 'email';
      $register_errors['message'] .= $this->getErrors('email');
   }

   if (!$this->validate(array('password')) {
      $register_errors['field'] = 'password';
      $register_errors['message'] .= $this->getErrors('password');
   }
}

or assign the different message to different $register_errors['message'][]

public function signup() {
   if (!$this->validate(array('name')) {
      $register_errors['field'] = 'name';
      $register_errors['message'][] = $this->getErrors('name');
   }

   if (!$this->validate(array('email')) {
      $register_errors['field'] = 'email';
      $register_errors['message'][] = $this->getErrors('email');
   }

   if (!$this->validate(array('password')) {
      $register_errors['field'] = 'password';
      $register_errors['message'][] = $this->getErrors('password');
   }
}

var_dump(  $register_errors['message']);
