简单验证

支持简单定义一个验证器并进行验证:

try {
    $data = Validate::make([
        'user' => 'required|email',
        'pass' => 'required|lengthBetween:6,16',
    ], [
        'user.required'      => '请输入用户名',
        'user.email'         => '用户名格式错误',
        'pass.required'      => '请输入密码',
        'pass.lengthBetween' => '密码长度为6~16位',
    ])->check($data);
} catch (ValidateException $e) {
    echo $e->getMessage();
}

如果验证通过,则返回所有通过验证的值,如未通过,则抛出一个W7\Validate\Exception\ValidateException异常

验证器定义

为具体的验证场景或者数据表单定义验证器类,我们需要继承W7\Validate\Validate类,然后实例化后直接调用验证类的check方法即可完成验证,下面是一个例子:

我们定义一个LoginValidate验证器类用于登录的验证。

class LoginValidate extends Validate
{
    protected $rule = [
        'user' => 'required|email',
        'pass' => 'required|digits_between:6,16',
    ];
    
    protected $message = [
        'user.required'       => '请输入用户名',
        'user.email'          => '用户名格式错误',
        'pass.required'       => '请输入密码',
        'pass.digits_between' => '密码长度为6~16位',
    ];
}
类属性定义的错误消息,优先级要高于自定义规则中的默认回复,高于自定义规则方法返回的错误

数据验证

$data = [
    'user' => '123@qq.com',
    'pass' => ''
];
$validate = new LoginValidate();
$validate->check($data);

此时会抛出一个W7\Validate\Exception\ValidateException异常,message为请输入密码

$data = [
    'user' => '123@qq.com',
    'pass' => '123456'
];
$validate = new LoginValidate();
$data = $validate->check($data);

验证成功,并返回通过验证的值,返回的值为数组类型

验证数组

验证表单的输入为数组的字段也不难。你可以使用 「点」方法来验证数组中的属性。例如,如果传入的 HTTP 请求中包含search[keyword]字段, 可以如下验证:

protected $rule = [
    'search.order'   => 'numeric|between:1,2',
    'search.keyword' => 'chsAlphaNum',
    'search.recycle' => 'boolean',
];

你也可以验证数组中的每个元素。例如,要验证指定数组输入字段中的每一个 id 是唯一的,可以这么做:

protected $rule = [
    'search.*.id' => 'numeric|unique:account'
];

数组规则的错误消息的定义也一样

protected $message = [
    'search.order.numeric'       => '排序参数错误',
    'search.order.between'       => '排序参数错误',
    'search.keyword.chsAlphaNum' => '关键词只能包含中文,字母,数字',
    'search.recycle.boolean'     => '参数错误:recycle',
];

验证器类属性

$rule

用户定义验证器的验证规则,也可以通过setRules方法来进行设置,此方法为叠加,如果参数为null则为清空全部规则

// 类中定义
protected $rule = [
    'user' => 'required'
];

// 使用方法定义
$v->setRules([
    'user' => 'required'
]);

$message

用户定义验证器的错误信息,也可以通过setMessages方法来进行设置,此方法为叠加,如果参数为null则为清空全部错误消息

// 类中定义
protected $message = [
    'user.required' => '账号必须填写'
];

// 使用方法定义
$v->setMessages([
    'user.required' => '账号必须填写'
]);

$scene

定义验证场景的数据,用于指定验证场景对应的验证字段等,详细用法查看验证场景一节,同样也可以通过setScene方法来进行设置,此方法为叠加,如果参数为null则为清空全部验证场景

// 类中定义
protected $scene = [
    'login' => ['user', 'pass']
];

// 使用方法定义
$v->setScene([
    'login' => ['user', 'pass']
]);

$event

定义此验证器下的全局事件,详细用法查看事件一节

protected $event = [
    CheckSiteStatus::class
];

$customAttributes

定义验证字段的名称,也可以通过setCustomAttributes方法来进行设置,此方法为叠加,如果参数为null则为清空全部字段名称, 错误消息中的:attribute会使用下面的值对应的替换

protected $customAttributes = [
    'user' => '账号',
    'pass' => '密码'
];

$default

定义字段的默认值

protected $default = [
    'name' => '张三'
];

关于默认值的详情请查看默认值一节

$filter

用于数据验证后处理数据

protected $filter = [
    'name' => 'trim'
];

关于过滤器的详情请查看过滤器一节

$ruleMessage

类方法规则的错误信息

 protected $ruleMessage = [
    ':attribute的值只能具有中文'
];

点击查看示例

$filled

所有验证的字段在存在时不能为空,如果此属性值为true,所有规则会自动增加filled规则,默认为true

当出现以下情况时,不会自动添加filled规则

  • 验证规则中存在filled, nullable, accepted, present,required, required_if, required_unless, required_with,required_with_all, required_without, required_without_all规则
  • 验证规则存在extendImplicit定义的规则
  • 验证规则存在extendImplicitRule定义的规则
  • 验证规则实现了Itwmw\Validation\Support\Interfaces\ImplicitRule标记接口
protected bool $filled = true;

$regex

预定义正则表达式验证规则,详情查看正则表达式规则

protected $regex = [
    'number' => '/^\d+$/'
];

$group

定义验证规则组

protected $group = [
    'username' => 'alpha_num|min:5|max:10'
];

protected $rule = [
    'username' => 'required|username'
];
