php - 想要存储图像路径

Question

我正在尝试制作一个应用程序，注册用户必须上传个人资料图片。 之后，当用户及其其他凭据登录时，也应该显示用户的图像。我还想将图像的路径传递到MySql中的表中。我的图像存储在服务器的文件夹中，而用户详细信息存储在 MySql 的表中。因此，当用户与凭据一起登录时，图像也应该显示。但是当我尝试注册时出现错误并且图像未上传。我的应用程序崩溃了。

PHP 文件:

<?php

  $con=mysqli_connect("mysql8.000webhost.com","a6391170_root","root123","a6391170_sanjay");

  $name = $_POST["name"];
  $age = $_POST["age"];
  $username = $_POST["username"];
  $password = $_POST["password"];
  $name1=$_POST["name1"];


  $imagepath="pictures1/" . $name1 . ".JPG";

  $statement = mysqli_prepare($con, "INSERT INTO `user1` (name, age, username, password,name1,imagepath) VALUES (?, ?, ?, ?,?,?)");
  mysqli_stmt_bind_param($statement, "sissss", $name, $age, $username, $password,$name1,$imagepath);
  mysqli_stmt_execute($statement);

  mysqli_stmt_close($statement);

  mysqli_close($con);
