php/mysql issue

[mojavewolfpup]

I finally have a working database script, I can add some data into it using a web based form instead of manually putting it in via sql scripting commands, but editing it is a different story.

for example, i'll use "95811" as a code, and that gets added, and for another "pin cart #3" that gets added fine, but if I decide to change "pin cart #3" to "pin cart #4" the edit code will accept it, but then switch "pin cart #4" to "95811" so I have that in the database twice

any idea what would be going on? i'm stumped.

I hope the code below helps, it's what I use. I will be adding in other sql fields also, not just the 2 pictured below so I don't know if that would effect anything also.

<html>
<head>
<title>Edit An Article</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<style type="text/css">
<!--
.box {
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
border: 1px solid #000000;
}
-->
</style>
</head>

<body>
<?php
include 'library/config.php';
include 'library/opendb.php';

if(isset($_GET['id']))
{
$query = "SELECT id, pinpicsnumber, source".
"FROM adventureland ".
"WHERE id = '{$_GET['id']}'";
$result = mysql_query($query) or die('Fatal Database Error: Contact via AIM Immediately! ' . mysql_error());
list($id, $pinpicsnumber, $source) = mysql_fetch_array($result, MYSQL_NUM);

$source = htmlspecialchars($source);
}
else if(isset($_POST['pinpicsnumber']))
{
$id = $_POST['id'];
$pinpicsnumber = $_POST['pinpicsnumber'];
$source = $_POST['source'];

if(!get_magic_quotes_gpc())
{
$pinpicsnumber = addslashes($pinpicsnumber);
$source = addslashes($pinpicsnumber);
}

// update the article in the database
$query = "UPDATE adventureland ".
"SET pinpicsnumber = '$pinpicsnumber', source = '$source' ".
"WHERE id = '$id'";
mysql_query($query) or die('Fatal Database Error: Contact via AIM Immediately! ' . mysql_error());

// then remove the cached file
$cacheDir = dirname(__FILE__) . '/cache/';
$cacheFile = $cacheDir . '_' . $_GET['id'] . '.html';

@unlink($cacheFile);

// and remove the index.html too because the file list
// is changed
@unlink($cacheDir . 'index.html');

echo "<p align='center'>Article updated</p>";

// now we will display $title & content
// so strip out any slashes
$pinpicsnumber = stripslashes($pinpicsnumber);
$source = stripslashes($source);
}

include 'library/closedb.php';
?>
<form method="post" action="cms-edit.php">
<input type="hidden" name="id" value="<?php echo "$id";?>">
<table width="700" border="0" cellpadding="2" cellspacing="1" class="box" align="center">

Your code appears to be vulnerable to SQL injection attacks. You really ought to fix it up before you get pwned.

Your UPDATE statement seems reasonable enough to me, but you've told us nothing at all about your database. I can't guess how you'd get two items with the same ID in your table form this code alone.

I don't know where to start with the database, and as for sql injection attacks, I have no idea. This program has been a bitch from the start, I wouldn't even know how to fix that problem when I can't get these to work!

That's the best I can do, i'm not sure what else to say at this point dealing with it.
