**数据库连接中没有错误。图片也成功保存在文件夹中，但没有数据插入mysql。请协助..非常感谢您的帮助！

也许这会有所帮助

$query="INSERT INTO uploads(file_name,file_size,file_type,description)VALUES('".$_FILES['image']['name']."',".$_FILES['image']['size'].",'".$_FILES['image']['type']."','".$d."')";

$query="INSERT INTO uploads(file_name,file_size,file_type,description)VALUES('{$_FILES['image']['name']}',{$_FILES['image']['size']},'{$_FILES['image']['type']}','$d')";
mysql_query($query) or die(mysql_error());

我假设您的description字段不仅采用整数。将单引号括在要插入到数据库中的字符串两边。

mysql_query也已弃用。使用 mysqli 或 pdo 执行查询。

$query="INSERT INTO uploads(file_name,file_size,file_type,description)VALUES('{$_FILES['image']['name']}',{$_FILES['image']['size']},'{$_FILES['image']['type']}', '$d')"
mysql_query($query) or die(mysql_error());;
