Hi!

I have successfully uploaded my php files and my database but I get this message "Notice: Undefined index:" for every $_POST and $_GET in my code.

Why is this happening and how do I solve this problem?

Thanx in advance.

It is okay now. I've added this line at the beginning of all php files:

error_reporting(E_ALL & ~E_NOTICE);

So now there is no annoying warnings from server

i have the same problem with you..but my problem is the data that i enter in my php page must enter in my database but it's not working...in xampp it's works.can you help me?

here is my code..

require("connectionq.php");
?>
<?
$x=mysql_query("select Product_Brand from adapter");
$y=mysql_affected_rows();

echo "<form method=post><select name=prod>";

for($i=0;$i<$y;$i++)
{
$row=mysql_fetch_array($x);
$pnAME=$row['Product_Brand'];

echo "<option value=\"$pnAME\">$pnAME</option>";

}
echo "</select><input type=submit value=search></form>";
?>
<?
$q=mysql_query("Select * from adapter where Product_Brand='{$_POST['prod']}'");
$r=mysql_affected_rows();

for($i=0;$i<$r;$i++)
{
$row=mysql_fetch_array($q);
$id=$row['Product_ID'];
$pn=$row['Product_Brand'];
$pr=$row['Price'];
$st=$row['Stock'];
}
?>

<form method=post>
<table>
<tr>
<td>Product ID:</td>
