Quote:
Notice: Undefined index: id in C:\xampp\htdocs\invoice\getcheckno.php on line 6

Notice: Undefined index: taxrate in C:\xampp\htdocs\invoice\getcheckno.php on line 7


PHP Code:
<?php

$dbuser 'root';
$dbpass 'cookie';

$id $_POST['id']; //
$taxrate $_POST['taxrate']; //

$conn mysql_connect($dbhost$dbuser$dbpass);
             if(! 
$conn ) { die('Could not connect: ' mysql_error()); }
             else {
mysql_select_db('homedb');}

mysql_query("UPDATE numbers SET checkno=checkno+1"); 
$result=mysql_query("select checkno from numbers") or die ("Error - could not retrieve checkno from database");
$data=mysql_fetch_assoc($result);
echo 
"checkno ".$data['checkno'];
