Bug in Buy it now: Solved

There is a bug that causes auctions not to end when a user clicks buy it now.

After a user has clicked buy it now, a second user can go to that auction and click buy it now and become the winner instead of the original one.

I have found the problem. In defaults_auction.php you only close the auction if the amount sold is greater than the inventory. It should actually be if the amount sold is equal (or greater) than inventory.

// IF SOLD MORE THAN QTY EXPIRE LISTING
if($qty_sold > $qty){
  update_post_meta($post->ID,'listing_expiry_date','');
}

Should be:

// IF SOLD ALL OF QTY EXPIRE LISTING
if($qty_sold >= $qty){
  update_post_meta($post->ID,'listing_expiry_date','');
}
