This code is now obsolete and has been updated again.
Updated code to automatically bid on an eBay item, I’m currently using it myself if a loop of searched items.
Most of the changes are improved return status checking. For testing use one cent items with free shipping.
// MAIN BIDDING FUNCTION
// this function performs no checking on the input variables
// $username - the eBay user name
// $password - the eBay user password
// $item - the eBay item number to bid on
// $bid - the bid amount in local currency i.e. 5.67
// $link - referral link, can leave empty i.e. '' or use 'http://ebay.com'
function place_bid($username, $password, $item, $bid, $link) {
$cookies = dirname(__FILE__).'/cookies.txt';
//set success as default false
$success = false;
$bid_success = false;
