Functional of holding auctions on WordPress

The task: to implement the functional for the conduct of auctions with one feature - users need to pay the deposit in advance to participate in the auction.

As a basis, I decided to use the plugin Woo Auction, which has already implemented a system of auctions with deposits. However, the plugin was unfunctional and required serious changes.

What was done:
• The rate system is refined.
• Automatic page update is added when a new bet appears.
• Added the current rates on the auction page.
• Correction of many errors and shortcomings
