我在cakephp3中验证了什么

Question

我的代码中有一个问题validatin字段usign cakephp3.4.13

它始终显示“此字段不能为空”事件用户名字段具有值输入，但是当我删除userstable.php中的验证时，它将提交，但数据库中的用户名字段为空。

请帮帮我

Userstable.php

 public function validationDefault(Validator $validator)
    {

$validator
    ->integer('id')
    ->allowEmpty('id', 'create'); 

   $validator->requirePresence('username', 'Please enter username.');
$validator
    ->requirePresence('password', 'create')
    ->notEmpty('password', 'You must enter a password', 'create')
        ->add('password', [
            'length' => [
            'rule' => ['minLength', 8],
            'message' => 'Passwords must be at least 8 characters long.',
        ]
    ]);
$validator
    ->requirePresence('age', 'create')
    ->notEmpty('age');
$validator
    ->requirePresence('address', 'create')
    ->notEmpty('address');
$validator
    ->email('email')
    ->requirePresence('email', 'create')
    ->notEmpty('email');
$validator
    ->requirePresence('gender', 'create')
    ->notEmpty('gender');
return $validator;
    }


public function buildRules(RulesChecker $rules)
    {
        $rules->add($rules->isUnique(['email']));
        $rules->add($rules->isUnique(['username']));
        return $rules;
    }
