我按照此tutorial将图片上传到服务器。
现在我的问题是如何在上传完成后修改代码以将图像路径另外保存到MySql数据库中？请帮助解决此问题。

将图像存储在服务器上的PHP文件：
<?php
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
?>

SQL：
CREATE TABLE `uploads` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`filename` varchar(255) NOT NULL,
`path` varchar(255) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
PHP：
$file_path = "uploads/";
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
// replace $host,$username,$password,$dbname with real info
$link=mysqli_connect($host,$username,$password,$dbname);
mysqli_query($link,"INSERT INTO `files` (filename,path) VALUES ('".$_FILES['uploaded_file']['tmp_name']."','".$file_path."')") or trigger_error($link->error."[ $sql]");
