验证场景
版本 新增功能
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);
