Question

我有一个名为validate()的方法，它接受数组作为参数。

E.g。

$v->validate([
    'username' => [$username, 'required'],
    'email'    => [$email, 'required'],
    'password' => [$password, 'required'],
]);

所以我想做的是，为此创建动态参数。但是，不知道正确的用语。例如！

$v->validate([
    'username' => [$username, 'required'],
    'email'    => [$email, 'required'],
    'password' => [$password, 'required'],            
    $validate_parameters
]);

类似的东西，这个固定字段和其他动态字段将作为参数发送。它将被翻译为：

$v->validate([
    'username'       => [$username, 'required'],
    'email'          => [$email, 'required'],
    'password'       => [$password, 'required'],
    'dynamicfield_1' => ['value_1', 'rule_1'],
    'dynamicfield_2' => ['value_2', 'rule_2'],
    'dynamicfield_3' => ['value_3', 'rule_3'],
]);

这是我的方法。

public function validateDynamicFields($compressed_field, $rules) {

    $parameters = '';

    foreach ($compressed_field as $key => $value) {

        // Well technically this will not work since it's not even an array or some sort.
        $parameters .= $key => [$value, $rules];

        // I even tried this and hope that it would work but it doesn't
        // $parameters .= "'{$key}' => [{$value}, '{$rules}'],";

    }

    return $parameters;
}

问题是，如何为validate()方法创建动态数组值？

Answer 1

您可以使用array_merge：

$v->validate(array_merge(
    [
      'username' => [$username, 'required'],
      'email'    => [$email, 'required'],
      'password' => [$password, 'required']
    ],
    $validate_parameters
));

Answer 2

我不确定你要完成什么，但也许是这样的：它分别创建两个数组，然后合并它们

$staticFields = [
    'username' => [$username, 'required'],
    'email'    => [$email, 'required'],
    'password' => [$password, 'required']
];

//this can be assigned with your DynamicFields function
$dynamicFields =  [
    'dynamicfield_1' => ['value_1', 'rule_1'],
    'dynamicfield_2' => ['value_2', 'rule_2'],
    'dynamicfield_3' => ['value_3', 'rule_3']
];

//merge both arrays, and pass them
$v->validate(array_merge($staticFields, $dynamicFields));

String as Array将在接受为数组的函数中发送的值
