编写验证规则：
<?php
declare (strict_types = 1);
namespace app\validate;
use think\Validate;
class Relation extends Validate {
protected $rule = [
'goods_name' => 'require|max:25',
'goods_stock' => 'require|number|egt:0',
'goods_price' => 'require|float|egt:0',
];
protected $message = [
'goods_name.require' => '商品名称不能为空或者不能大于25个字符',
'goods_stock.require' => '商品库存不能为空',
'goods_stock.number' => '商品库存只能是大于0的整数',
'goods_stock.egt' => '商品库存不能小于0',
'goods_price.require' => '商品价格不能为空',
'goods_price.float' => '商品价格只能为数字',
'goods_price.egt' => '商品价格不能小于0',
];
protected $scene = [
'add' => ['goods_name','goods_stock','goods_price'],
'edit' => ['goods_name','goods_stock'],
];
}
?>
控制器中调用验证规则
<?php
declare (strict_types = 1);
namespace app\controller;
use app\BaseController;
use think\Request;
use think\response\Json;
use app\validate\Relation as relationValidate;
class relation extends BaseController{
//验证器
public function index() : Json {
$data = Request()->param();
$relation = new relationValidate();
if (!$relation->scene("edit")->check($data)) {
return json(['code'=>'1','msg'=>$relation->getError()]);
}
return json(['code'=>'0','msg'=>'验证成功','data'=>$data]);
}
}
?>
