Question

我为图片表单创建了验证规则。

它在存储方法上工作正常，但我不希望在更新时需要图像字段，因为我可能只更新标题，例如。

class ImageRequest extends Request
{   
    /**
     * Rules array
     */
    protected $rules = [
        'title' => 'required|string|between:3,60',
        'alt'   => 'sometimes|string|between:3,60',
        'image' => 'required|image|max:4000|dimensions:min_width=200,min_height=200',
    ];

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return $this->rules;
    }
}

对于唯一验证，我们可以添加自定义查询条件：

'email' => Rule::unique('users')->ignore($user->id, 'user_id')

或

'email' => Rule::unique('users')->where(function ($query) {
    return $query->where('account_id', 1);
})

对于必需来实现类似的东西是否干净？

仅对新图片应用必需。

Answer 1

您可以在规则

中使用switch语句

 public function rules()
    {

        switch ($this->method()) {
            case 'GET':
            case 'DELETE': {
                return [];
            }
            case 'POST': {

                      return [
                          'first_name'=>'required',
                          'last_name'=>'required',
                        'email'=>'required|email|unique:users,email,'.$this->id,
                          'password'=>'',
                          'dob'=>'required',
                          'phone_one'=>'required',
                          'phone_two'=>'required',
                          //'user_role'=>'required',
                      //    'profile_image'=>'required'
                      ];
            }
            case 'PUT':
            case 'PATCH': {
                return [

                ];
            }
            default:break;
        }

另外你可以像更新时使用condtion yuo有这样的基础，你可以检查它的更新或插入，因为插入你没有id所以

Answer 2

创建另一个将Request类扩展到更新控制器操作中的类

class UpdateImageRequest extends Request
{   
    /**
     * Rules array
     */
    protected $rules = [
        'title' => 'required|string|between:3,60',
        'alt'   => 'sometimes|string|between:3,60'
    ];

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return $this->rules;
    }
}

Answer 3

更好的方法是在Laravel 5.5验证中使用nullable

参考Docs

验证字段可能为空。这特别有用在验证原语时，如字符串和整数可以包含空值。

class ImageRequest extends Request
{   
    /**
     * Rules array
     */
    protected $rules = [
        'title' => 'required|string|between:3,60',
        'alt'   => 'nullable|string|between:3,60',
        'image' => 'nullable|image|max:4000|dimensions:min_width=200,min_height=200',
    ];

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return $this->rules;
    }
}

然而，我最近使用了图像，它对我来说就像魅力一样。试一试！

在这种情况下最简单的方式是另一种方式。默认情况下，有更新规则，如果它的商店添加需要，如下所示：

class ImageRequest extends Request
{   
    /**
     * Rules array
     */
    protected $rules = [
        'title' => 'required|string|between:3,60',
        'alt'   => 'sometimes|string|between:3,60',
        'image' => 'image|max:4000|dimensions:min_width=200,min_height=200',
    ];

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        $rules = $this->rules;

        if ($this->isMethod('POST')) {
           $rules['image'] = 'required|' . $rules['image']
        }

        return $rules;
    }
}

Answer 5

我找到了解决方案。

我将图片重命名为文件。

商店上更新和 homestead.app/images 的路线 homestead.app/images/1 >所以 $ image 属性将 $ this-＆gt; image = 1 更新和 $ this-＆gt 商店上的; image = null 。

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <netinet/in.h>
#include <sys/socket.h>

int main() {

    int network_socket;

    network_socket = socket(AF_INET, SOCK_STREAM, 0);

    //specify an address for the socket

    struct sockaddr_in server_address;
    server_address.sin_family = AF_INET;
    server_address.sin_port = htons(9002);
    server_address.sin_addr.s_addr = inet_addr("192.168.1.5");

    int connection_status = connect(network_socket, (struct sockaddr *) &server_address, sizeof(server_address));
    char server_response[256];
    recv(network_socket, &server_response, sizeof(server_response), 0);
    printf("THE SERVER SENT THE DATA: %s \n", server_response);

    close(network_socket);
    return 0;
}
