Question

我有一个功能完善的书签应用程序。截至目前，它是非排他性的;当我按下“保存”书签时，它会将URL发送到DB中的通用表。我需要弄清楚如何将其与在线社区集成，因此其用户特定以及每次用户“保存”故事时，它会将URL发送到数据库中该用户的行并输出回来该用户的个人资料。

代码如下。这是一个演示： http://demo.tutorialzine.com/2010/04/simple-bookmarking-app-php-javascript-mysql/demo.php

Bookmark.php

 <?php

 // Error reporting:
 error_reporting(E_ALL^E_NOTICE);

 require "connect.php";
 require "functions.php";

 // Setting the content-type header to javascript:
header('Content-type: application/javascript');

 // Validating the input data
if(empty($_GET['url']) || empty($_GET['title']) || !validateURL($_GET['url'])) die();

// Sanitizing the variables
$_GET['url'] = sanitize($_GET['url']);
$_GET['title'] = sanitize($_GET['title']);

// Inserting, notice the use of the hash field and the md5 function:
mysql_query("   INSERT INTO bookmark_app (hash,url,title)
            VALUES (
                '".md5($_GET['url'])."',
                '".$_GET['url']."',
                '".$_GET['title']."'
            )");

$message = '';
if(mysql_affected_rows($link)!=1)
{
$message = 'You have already saved this Headline';
}
else
$message = 'The URL was shared!';

   // Adding the message passed to the function as text:

   // Appending the div to document
 document.body.appendChild(d);

   // The message will auto-hide in 3 seconds:

 setTimeout(function(){
    try{
        document.body.removeChild(d);
    }   catch(error){}
