Question

我想从android应用程序上传图片，但是它在第13行的xampp \ htdocs \ CityHero \ user_registration.php中生成未定义索引错误：user_pic ...
我无法理解与此错误相关的问题。.
user_registration.php

这是我的Android Studio上传代码。

    <?php
require "config.php";

$obj = new config();

$er = 0;
$filename = ""; 

$return = array();

if (isset($_POST["user_name"]) && isset($_POST["user_email"]) && isset($_POST["user_city"]) && isset($_POST["user_area"]) && isset($_POST["username"]) && isset($_POST["password"])) {

    if ($_FILES['user_pic']["name"] != "") {
        $type = "." . pathinfo($_FILES['user_pic']['name'],PATHINFO_EXTENSION);

        if ($type == ".jpeg" || $type == ".png" || $type == ".jpg" || $type == ".bmp") {
            $filename = date("d-m-Y-H-i-s").$type;
            $file_server_path = $obj->SERVERPATH . basename($filename);
            move_uploaded_file($_FILES['user_pic']['tmp_name'], $file_server_path);

            $return["STATUS"] = true;
            $return["MSG"] = "FILE UPLOADED SUCCESSFULLY...";
        }else{
            $er = 1;
            echo "Error!!!Please Check Code Once Again....";
            // echo $return["STATUS"] = false;
            // echo $return["MSG"] = "ERROR!!! Please Check Code once again....";
        }

        if ($er == 0) {
            $insData["user_name"] = $_POST["user_name"];
            $insData["user_email"] = $_POST["user_email"];
            $insData["user_city"] = $_POST["user_city"];
            $insData["user_area"] = $_POST["user_area"];
            $insData["username"] = $_POST["username"];
            $insData["password"] = md5($_POST["password"]);
            $insData["create_date"] = $obj->current_date;
            $insData["modify_date"] = $obj->current_date;
            $insData["remote_ip"] = $obj->remote_ip;
            $insData["user_pic"] = $filename;

            $result = $obj->myInsdata("users_registration",$insData);

            if ($result) {
                echo "Insertion Succesfull";
                // echo $return["STATUS"] = true;
                // echo $return["MSG"] = "INSERTED SUCCESSFULLY...";                
            }else{
                echo "Error!!!Please Check Code Once Again....";
                // echo $return["STATUS"] = false;
                // echo $return["MSG"] = "INSERTED NOT SUCCESSFULL...";     
            }
        }
    }
}else{

    // echo $return["STATUS"] = false;
    // echo $return["MSG"] = "FIELD IS NOT SET..";

您可以使用Gotev Upload Service

上传图片

在gradle依赖中

dependencies {  
   implementation "net.gotev:uploadservice:3.4.2"
}

然后参加活动

public void uploadMultipart(final Context context) {    
    try {  
        String uploadId =  
                new MultipartUploadRequest(context, "your URL here")  
                        .addFileToUpload("data.getData() here", "user_pic")                           
                        .addParameter("user_name", "param value") 
                        .addParameter("user_email", "param value") 
                        .addParameter("user_city", "param value") 
                        .addParameter("user_area", "param value") 
                        .addParameter("username", "param value")  
                        .addParameter("password", "param value")        
                        .setNotificationConfig(new UploadNotificationConfig())  
                            .setMaxRetries(2)  
                            .startUpload();  

        } catch (Exception exc) {  
            Toast.makeText(context, "Exception: "+exc.getMessage(), Toast.LENGTH_SHORT).show();  
        }  
    }
