I have 2 files.

submit.html ************************************


<html>
<head>
<title>New Submissions</title>
</head>

<body>
<form method="post" action="add.php">
<input type="hidden" name="id" value="null">
<input type="hidden" name="reviewed" value="no">
<input type="hidden" name="accepted" value="no">
<table>
<tr><td align="left">Name</td>
<td><input name="name" maxlength="255"></td>
</tr>
<tr><td align="left">Site name</td>
<td><input name="site_name" maxlength="255"></td>
</tr>
<tr><td align="left">Url</td>
<td><input name="url" maxlength="255"></td>
</tr>
<tr><td align="left">Email</td>
<td><input name="email" maxlength="255"></td>
</tr>
<tr><td colspan="2">

<input type="submit" value="submit">
</td>
</tr>
</table>
</form>
</body>
</html>

add.php **************************************


<?
$DBhost = "localhost";
$DBuser = "designers_hub";
$DBpass = "";
$DBName = "designers_hub";
$table = "link_submissions";
mysql_connect($DBhost,$DBuser,$DBpass) or die("Unable to connect to database");

@mysql_select_db("$DBName") or die("Unable to select
database $DBName");

$sqlquery = "INSERT INTO $table
VALUES('$id','$name','$site_name','$url','$email','$reviewed','$accepted')";

$results = mysql_query($sqlquery);

mysql_close();

?>

It will only enter in a new record with no information. I get this:
Notice: Undefined variable: id in c:\program files\apache group\apache\htdocs\link_submission\add.php on line 13

Notice: Undefined variable: name in c:\program files\apache group\apache\htdocs\link_submission\add.php on line 13
