Add UI to specify number of subscriptions-per-product. Probably best as a per-product setting, in the advanced tab. (check out subscription limiting setting for reference)

Checklist for testing:

• Cache is created correctly on plugin activation
• Cache is deleted on plugin deactivation
• Cache is updated correctly when subscription statuses change
• Cache is updated correctly when subscription is purchased
• Unrestricted subscription products can be purchased normally
• Simple subscription is not visible in shop and not purchasable, when restricted
• Variable subscription is not visible in shop and variations are not purchasable, when product is restricted
• Not allowing multiple quantities from making it through the cart if it bumps above the restricted number
• Place product in cart/checkout, then restrict it and try to checkout
• Manual Renewal should still work for a restricted product
• Paying for a failed renewal order should still work for a restricted product
• Switching between grouped simple products should prevent purchase if the one being switched to is restricted
• Switching between variations of a variable product should bypass the restriction, since restriction is set on a product level
• Resubscription should not work if the product became restricted since the sub was cancelled or expired
• Restriction can be set sitewide in Subs settings and also from product page
• Product-level restriction setting will override storewide setting

Create settings toggle that will affect whether the 'visibility' of a product is affected by this plugin.

Some customers want to still have their products be visible in the catalog, etc, even if they are not purchasable.

Edit: one possible solution to this might be to tie into the default WooCommerce "Out of Stock Visibility" toggle.

I am having an issue where one of my customers cannot purchase a subscription. It set to have one active subscription at a time but there are no active subscriptions currently for the specific product.

I see the product listed in the cache but I can't clear the cache when deactivating the plugin. How can I clear the cache?

This is coming from a request to have a 4-to-1 relationship between subs and product. To work this into the plugin, there would need to be an entry in the cache for each time a subscription was added, so this line would need to be removed: https://github.com/Prospress/woocommerce-subscriptions-one-to-one/blob/master/wcs-one-to-one.php#L93

Also, instead of checking if the value is in the cache, we'd need to check for a specific number of times it's in there, here: https://github.com/Prospress/woocommerce-subscriptions-one-to-one/blob/master/wcs-one-to-one.php#L122

For example, if your product is restricted to "1" subscription, you could still add a quantity of "2" to the cart and be able to check out with that, since we aren't validating the cart. We are only making the item not purchasable if there already exist that many subscriptions for it when visiting the product page.

I can't think of any way to address this, so it's possible that this plugin will only work if "limit to one" is set, to prevent this.

Subscriptions created in the admin area won't add to the cache, only ones purchased the normal way through the checkout process.

Perhaps the cache can be refreshed after manual creation, or there's a hook I'm missing where I can add it to the cache.

Product hidden from shop page - but should there also be a warning when viewing single product page directly?

Perhaps a deactivation of 'add to cart' button?

This is a feature request that I predict will happen. I can add it in at a later date if it becomes necessary.

Would need to customize:

• Single product warning
• Cart warning
• Default WooCommerce "is not purchasable" alert box

Could set as a storewide setting in the options, or on a product level.

Another option might be to make it translatable, so that people could use Say What? to change the text themselves. That would have the added benefit of making it translatable for international users as well.

If a site has a large number of unended subscriptions, there could be performance issues when activating the plugin.

wcs_get_subscriptions can be run in batches of 50 or so to prevent that: https://github.com/Prospress/woocommerce-subscriptions-restrict-product/blob/master/wcs-restrict-product.php#L98

Hi there.

I have installed it and set the limit to 6 on a product with 6 active subscriptions and it is not doing anything.

Basically you can still add the product to the cart. and If I change the quantity available to 0 or make the product Out of stock renewals do not work as they can not be added to the cart if the product is out of stock.

I have read the note about not restricting retroactively. Does this mean if I have 8 active subscriptions before I install the plugin it wont start restricting until 8 more are booked?

Thanks

For example, if sitewide restriction is set at '1', there's no way to explicitly set the product-level restriction to '0' to deactivate it for that product.

Possibly add a checkbox to 'activate product-specific restriction' or something very obvious like that.

Currently, the plugin doesn't account for multiple quantities of a subscription being added to the cart. When hooking into woocommerce_subscription_is_purchasable I need to also check if there are multiple quantities in the cart, and add those to my check.

Here's the spot where it probably should happen: https://github.com/Prospress/woocommerce-subscriptions-restrict-product/blob/master/wcs-restrict-product.php#L209

Hi there,

First of all, thank you for the plugin. :) Secondly, I have a store with 3 different types of subscriptions each with a monthly and yearly option. Because these are relatively different products we have them separately (and not as variable).

Is there an option that limits the active subscriptions per user to one but lets the user buy another subscription instead of their current one? In this case, users could upgrade or downgrade but have only one subscription at any given time.

Thank you very much for your help in advance.

Best regards,
Gabor

It might be nice for admins to see the current running list of products with active subscriptions. This could be as a JS hidden area on the subscriptions options tab, or a separate page.

Product restriction is not bypassed as it should be when clicking "renew now" to renew a manual renewal early.

Need to verify that this isn't just subs going into "pending cancellation."

Hi, thanks in advance for share this enhance for this plugin.
