Question

我试图让yii2验证我的ActiveForm字段，该字段应为数字且长度为8个字符。

以下是我在LoginForm的默认yii2/advanced/backend模型中尝试过的内容，但不幸的是isNumeric验证程序根本没有启动：

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.');
        }
    }
}

我还尝试按照相关帖子（https://stackoverflow.com/a/27817221/2037924）中的建议添加方案，但只有在方案中没有包含password字段时才会起作用（如显示错误）。 / p>

这是实现这一目标的好方法，还是你能想出更好的方法吗？

注意：我将username定义为string的原因是因为这些数字可能包含前导0＆＃39>。

Answer 1

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 2

在此处详细了解验证：http://www.yiiframework.com/doc-2.0/guide-tutorial-core-validators.html#number

使用yii2-basic

中的联系表格，这对我来说很好

/**
 * @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 3

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

        // ...
    ];
}

Answer 4

尝试一下：

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'],
];
}
