Php 列'；图像'；不能为空

我已经建立了数据库，我的php表单将图像上传到我希望它正常运行的文件夹中。但是，在数据库中，它只是表示图像为null，如果我将其更改为not null，则会出现一个错误，即： 注意：未定义的索引：第45行C:\xampp\htdocs\sws\u blog\admin\add\u image\u post.php中的图像 列“image”不能为空

我试图建立一个定制的PHP博客，只有我会发布/上传到它。我有不同的帖子类型，比如“图片帖子”和“视频帖子”

我无法为我上载图像的帖子显示图像

这是我的add_image_post.php：

    <?php require_once('../Connections/blog.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

添加图像帖子
添加图像帖子

应该是

GetSQLValueString($_FILES['image']['name'], "text"));


很可能

GetSQLValueString($_FILES["image"], "name"));

也应该

GetSQLValueString($_FILES['image']['name'], "text"));

您的
开关
案例中没有
名称
作为
$类型
。
在一个
插入
中，您使用的是
$\u POST['image']
，在另一个案例中，您使用的是
$\u文件['image']
。这是故意的吗？还有，哪一行是45？发生错误是因为您尝试为图像插入的值为空。。。现在我们必须弄清楚为什么它是空的。是不是传错了？你指的是错误的东西吗？正确的方法不正确吗？还有，该函数，
GetSQLValueString
。。。当您将其用于图像时，在第二次插入中将
name
作为第二个参数传递。它没有处理这一问题的理由。归还什么？
$\u文件['image']
和
$\u POST['image']
是否都存在并具有您期望的值？最初使用$POST['image']将图像路径保存到数据库中。但我并不完全理解这是如何实现的。我将如何重命名上传的图像以与该帖子相关联？
GetSQLValueString($_FILES["image"], "name"));

GetSQLValueString($_FILES['image']['name'], "text"));
