Allow WooCommerce inventory stock to be reduced when adding items to cart and/or expire items from the cart

WooCommerce doesn't remove an item from inventory until someone actually buys that item. This plugin can reduce the "virtual" stock quantity of an item without actually modifying the item inventory, so there should be no problems with missing data if somehow the cart data is deleted. This plugin isn't for everyone, but people that are selling specialty items will find it useful and hopefully eliminate some customer support nightmares.

The plugin can automatically expire items from the cart (disabled by default) with a configurable expiration time. Expiration times are plain english using whatever types php's strtotime can support (Examples: 10 minutes, 1 hour, 6 hours, 1 day) Per item expiration time can be configured by adding a Custom Field to each item using the configured 'Expire Custom Key' (default name is 'csr_expire_time').

Expiration can be enabled independently of reducing the cart stock, so this plugin can also be used to expire items at other intervals than the default WooCommerce cart/session expiration.

An issue was opened on the WooCommerce issue tracker regarding this problem and someone posted on Facebook about it, which caught my attention.

Please submit bug reports, feature requests, and pull requests via the GitHub repository

1. Download plugin from GitHub or the wordpress.org repository
2. Upload plugin and activate through the 'Plugins' menu in WordPress
3. Configure plugin specific settings under the WooCommerce->Settings->Integration admin page

The first request that hits the server will get the item if there is only one available. The other person will receive a "Item is no longer available" message.

They will receive a "Quantity requested not available" message and their original quantity will be retained.

You can set this by using the 'wc_csr_min_no_check' filter. This is an advanced option and should only be used on high volume sites with predictable orders. The setting to use depends on your stock quantites and how much you expect to sell. If you have a stock of 100 and only expect to sell 10 per hour you could set this to 25 and set the expiration to one hour and you should be safe. Always err on the side of caution, you don't want to run out of stock when someone believes they will get an item. If in doubt, don't use this option.

We recommend turning off page and database caching for pages affected by this plugin. For example, assuming your site uses the default Woocommerce "shop" page and W3 Total Cache, add "shop/*" (without the quotes) to "Never cache the following pages:" at the page cache and database cache settings.

• If you are using WooCommerce >= 2.5 you must update to this version
• Refresh the page when an expiration countdown hits 0
• Allow sessions to be loaded from new table in WooCommerce >= 2.5

• Add 2 new options to append strings to the pending order text.
• Add 'wc_csr_stock_pending_text' filter (used internally) to replace pending order text
• Add a link from the plugins page to settings (Thanks Gabriel Reguly!)
• Cache stock value so we don't continually decrement the value every time we check it
• Add call to action 'wc_csr_before_remove_expired_item' to remove_expired_item function
• Add 'wc_csr_adjust_cart_expiration' action to adjust existing items expire time
• Move 'Expire Custom Key' from config to filter 'wc_csr_expire_custom_key'
• Move 'Minimum Stock to Skip Check' from config to a filter 'wc_csr_min_no_check'

• Allow countdown timer to be configured when it is shown (Always, Never, Only When Items are added)
• Allow cart expiration to happen without managing being enabled
• Add countdown timer instead of just displaying static string
• Added 'wc_csr_expiring_cart_notice' filter to allow changing of countdown text in cart
