Yii2：ActiveForm 字段数字，长度 => 8

Question

我正在尝试让 yii2 验证我的 ActiveForm 字段，该字段应该是数字且长度为 8 个字符。

以下是我在 yii2/advanced/backend 的默认 LoginForm 模型中尝试的方法，但不幸的是 isNumeric 验证器根本没有启动：

public function rules()
{
    return [
        // username and password are both required
        [['username', 'password'], 'required'],
        // username should be numeric
        ['username', 'isNumeric'],
        // username should be numeric
        ['username', 'string', 'length'=>8],
        // password is validated by validatePassword()
        ['password', 'validatePassword'],
    ];
}

/**
 * Validates if the username is numeric.
 * This method serves as the inline validation for username.
 *
 * @param string $attribute the attribute currently being validated
 * @param array $params the additional name-value pairs given in the rule
 */
public function isNumeric($attribute, $params)
{
    if (!is_numeric($this->username))
        $this->addError($attribute, Yii::t('app', '{attribute} must be numeric', ['{attribute}'=>$attribute]));
}

/**
 * Validates the password.
 * This method serves as the inline validation for password.
 *
 * @param string $attribute the attribute currently being validated
 * @param array $params the additional name-value pairs given in the rule
 */
public function validatePassword($attribute, $params)
{
    if (!$this->hasErrors()) {
        $user = $this->getUser();
        if (!$user || !$user->validatePassword($this->password)) {
            $this->addError($attribute, 'Incorrect username or password.');
        }
    }
}

我还尝试按照相关 post () 中的建议添加场景，但只有在我不包含 password 时才有效（如显示的错误）场景中的字段。

这是实现此目标的好方法吗，或者您能想到更好的方法吗？

注意： 我将 username 定义为 string 的原因是因为数字可能包含前导 0。

在此处阅读有关验证的更多信息：http://www.yiiframework.com/doc-2.0/guide-tutorial-core-validators.html#number

使用 yii2-basic 中的联系表对我来说效果很好

/**
 * @return array the validation rules.
 */
public function rules()
{
    return [
        // name, email, subject and body are required
        [['name', 'email', 'subject', 'body'], 'required'],
        // email has to be a valid email address
        ['email', 'email'],
        ['subject', 'is8NumbersOnly'],
        // verifyCode needs to be entered correctly
        ['verifyCode', 'captcha'],
    ];
}

public function is8NumbersOnly($attribute)
{
    if (!preg_match('/^[0-9]{8}$/', $this->$attribute)) {
        $this->addError($attribute, 'must contain exactly 8 digits.');
    }
}

Answer 2

尝试使用 integer 数据类型：

[['username'], 'integer'],
[['username'], 'string', 'min' => 8],

它将验证 numeric 和 length。这样就可以了。

Answer 3

public function rules()
{
    return [
        // username should be numeric
        ['username', 'match', 'pattern' => '/^\d{8}$/', 'message' => 'Field must contain exactly 8 digits.],

        // ...
    ];
}

Answer 4

试试这个：

public function rules()
{
return [
    // name, email, subject and body are required
    [['name', 'email', 'subject', 'body'], 'required'],
    // email has to be a valid email address
    ['email', 'email'],
    [['subject'], 'number'],
    [['subject'], 'string', 'max' => 8, 'min' => 8],
    // verifyCode needs to be entered correctly
    ['verifyCode', 'captcha'],
];
}
