图像不保存在 PHP 的数据库中

Question

用户登录他的个人资料后，我将显示他的用户个人资料。在那里我让他添加他的个人资料图片。用户添加他的个人资料图片后，我想将图片路径插入数据库。

登录时的数据库-id、用户名、密码、电子邮件

头像保存后的数据库 - id, username,password,email,name1(img path save)

以下代码将图片保存在给定的文件夹中，但它没有将图片路径保存在数据库中。有人可以帮我吗？

<?php include('header.php');?>
<?php include('config.php');?>
<?php
    // index.php
    session_start();
    if(!isset($_SESSION['username']))

     {
        header("Location: login.php");
    }
    $username = $_SESSION['username'];
    $sql = "SELECT *  FROM services WHERE user_name = '".$_SESSION['username']."'";
    $result = $con->query($sql);

    if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        ?>
    <?php

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

     $name = $_FILES['file']['name'];
    $target_dir = "upload/";
    $target_file = $target_dir . basename($_FILES["file"]["name"]);

    // Select file type
    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

    // Valid file extensions
    $extensions_arr = array("jpg","jpeg","png","gif");

    // Check extension
    if( in_array($imageFileType,$extensions_arr) ){

  // Insert record
  //$query = "insert into services(name1) values('".$name."') where user_name = '".$_SESSION['username']."'";
  $query = " UPDATE services SET name1='$name' where user_name = '".$_SESSION['username']."";
  mysqli_query($con,$query);

  // Upload file
  move_uploaded_file($_FILES['file']['tmp_name'],$target_dir.$name);

 }

}
?>

Answer 1

改变

$query = " UPDATE services SET name1='$name' where user_name = '".$_SESSION['username']."";

到

 $query = ("UPDATE services SET name1='$name' where user_name = '".$_SESSION['username']."") or die(mysqli_error($con));

我添加了mysqli_error。它将在查询和括号中打印错误
