我需要更新mysql数据库中的配置文件并在程序中设置用户类型。如何在此注册程序中上传图像？已经尝试了一切，php的新手，每次运行下面的程序时都会出错。如何删除存储的值？

Register.php 

<?php
session_start();
require('connect.php');

if(isset($_POST['submit'])){

$username = $_POST['username'];
$name = $_POST['name'];
$email = $_POST['email'];
$password = md5($_POST['password']);
$dob = $_POST['dob'];
$gender = $_POST['gender'];
$location = $_POST['location'];
$course = $_POST['course'];
$mobile = $_POST['mobile'];

 $query = "INSERT INTO `user`(username, name, password, email, dob, gender, location, course, mobile) VALUES ('$username', '$name', '$password',  '$email', '$dob', '$gender', '$location', '$course', '$mobile')";

       $result = mysqli_query ($mysqli,$query);
  if($result){
               $smsg = "Thank you!Your registration form has been successfully submitted.";
         }else{
               $fmsg = "This email already exists ";
             }
}

   ?>

您可以从表单中的post变量中获取文件，这是上传文件并将其保存到storage / uploads文件夹的代码

$info = pathinfo($_FILES['your_file_name']['name']);
$ext = $info['extension']; // get the extension of the file
$newname = "newname.".$ext; 

$target = 'avatar/'.$newname;
move_uploaded_file( $_FILES['your_file_name']['tmp_name'], $target);

此处是该帖子，可帮助您为文件名创建随机字符串（您可以将该文件名保存到数据库中）https://stackoverflow.com/a/13212994/5928015
