5.0.4 增加hasScene方法用于检查是否存在验证场景

可以在定义验证规则的时候定义场景，并且验证不同场景的数据，例如：

$rule = [

‘name’ => ‘require|max:25’,

‘age’ => ‘number|between:1,120′,

’email’ => ’email’,

];

$msg = [

‘name.require’ => ‘名称必须’,

‘name.max’ => ‘名称最多不能超过25个字符’,

‘age.number’ => ‘年龄必须是数字’,

‘age.between’ => ‘年龄只能在1-120之间’,

’email’ => ‘邮箱格式错误’,

];

$data = [

‘name’ => ‘thinkphp’,

‘age’ => 10,

’email’ => ‘thinkphp@qq.com’,

];

$validate = new Validate($rule);

$validate->scene(‘edit’, [‘name’, ‘age’]);

$result = $validate->scene(‘edit’)->check($data);

表示验证edit场景（该场景定义只需要验证name和age字段）。

如果使用了验证器，可以直接在类里面定义场景，例如：

namespace app\index\validate;

use think\Validate;

class User extends Validate

{

protected $rule = [

‘name’ => ‘require|max:25’,

‘age’ => ‘number|between:1,120′,

’email’ => ’email’,

];

protected $message = [

‘name.require’ => ‘名称必须’,

‘name.max’ => ‘名称最多不能超过25个字符’,

‘age.number’ => ‘年龄必须是数字’,

‘age.between’ => ‘年龄只能在1-120之间’,

’email’ => ‘邮箱格式错误’,

];

protected $scene = [

‘edit’ => [‘name’,’age’],

];

}

然后再需要验证的地方直接使用 scene 方法验证

$data = [

‘name’ => ‘thinkphp’,

‘age’ => 10,

’email’ => ‘thinkphp@qq.com’,

];

$validate = new \app\index\validate\User($rule);

$result = $validate->scene(‘edit’)->check($data);

可以在定义场景的时候对某些字段的规则重新设置，例如：

namespace app\index\validate;

use think\Validate;

class User extends Validate

{

protected $rule = [

‘name’ => ‘require|max:25’,

‘age’ => ‘number|between:1,120′,

’email’ => ’email’,

];

protected $message = [

‘name.require’ => ‘名称必须’,

‘name.max’ => ‘名称最多不能超过25个字符’,

‘age.number’ => ‘年龄必须是数字’,

‘age.between’ => ‘年龄只能在1-120之间’,

’email’ => ‘邮箱格式错误’,

];

protected $scene = [

‘edit’ => [‘name’,’age’=>’require|number|between:1,120′],

];

}

可以对场景设置一个回调方法，用于动态设置要验证的字段，例如：

$rule = [

‘name’ => ‘require|max:25’,

‘age’ => ‘number|between:1,120′,

’email’ => ’email’,

];

$msg = [

‘name.require’ => ‘名称必须’,

‘name.max’ => ‘名称最多不能超过25个字符’,

‘age.number’ => ‘年龄必须是数字’,

‘age.between’ => ‘年龄只能在1-120之间’,

’email’ => ‘邮箱格式错误’,

];

$data = [

‘name’ => ‘thinkphp’,

‘age’ => 10,

’email’ => ‘thinkphp@qq.com’,

];

$validate = new Validate($rule);

$validate->scene(‘edit’, function($key,$data){

return ’email’==$key && isset($data[‘id’])? true : false;

});

$result = $validate->scene(‘edit’)->check($data);
