## აღწერა
**WT Waitlist** is a “back in stock” waitlist for WooCommerce without bloat. Customers
leave their email on an out-of-stock product page, and when the stock returns —
the plugin sends a notification in the background through Action Scheduler.
Built by the [webmasters.team](https://webmasters.team) team. Open-source code,
no external APIs, all data stored locally in the WordPress database.
#### Key features
* **Signup form replaces Add to cart** for out-of-stock products, with variation
support (per size/color).
* **Custom database tables** (`{prefix}_waitlist_subscriptions`) — we do not clutter`
wp_postmeta`, the plugin scales to tens of thousands of subscriptions.
* **Action Scheduler queue** (bundled with WooCommerce): batch of 50 emails per
tick, automatic retries, retry log visible in `WooCommerce Status Scheduled
Actions`.
* **5 min throttle** per product — prevents duplicate sends when multiple hooks
fire (e.g. quantity change followed by status change).
* **One-click unsubscribe** via a link in the email (SHA-256 token), no confirmation
or login required.
* **GDPR-ready**: consent logging (anonymized IP, timestamp, user agent), integration
with WordPress Privacy Tools (export and erasure of data per email).
* **CSV export** of subscribers from the admin panel (streamed, no timeouts on
large lists).
* **Anti-spam**: honeypot plus rate limiter per IP (10 submissions per hour).
* **Theme compatibility**: classic themes (Storefront, Twenty Twenty-One/Two/Three)
plus block themes (Twenty Twenty-Four/Five) — the form attaches through a hook
for classic templates and through a `render_block` filter for FSE.
* **Zero external dependencies**: apart from WooCommerce, requires only plain PHP
8.0+.
#### Shortcode fallback
```
[wt_waitlist product_id="123"] — use this if your custom product template does not fire the standard hooks.
```
#### What WT Waitlist does NOT do (by design)
* No SMS, no Mailchimp/MailerLite integrations in the free version.
* No double opt-in (minimal flow — leave email, get notification).
* No WYSIWYG editor for email templates (HTML template lives in the plugin file,
override with the `wt_waitlist/notification_context` filter).
These features are planned for the Pro edition. The free edition covers 100% of
the core waitlist flow.

## დაყენება
1. Install and activate WooCommerce (required).
2. Install **WT Waitlist** via WP Admin Plugins Add new, or manually over FTP (folder`
wt-waitlist` in `wp-content/plugins/`).
3. Activate the plugin.
4. Open the **WT Waitlist** menu in the admin panel and configure data retention plus
the administrator notification email address.
On first activation the plugin creates its database tables and schedules a daily
job that purges old subscriptions.
## ხდკ
### How does the form appear on the product page?
Automatically — the plugin hooks into the standard WooCommerce action (`woocommerce_single_product_summary`)
for classic themes and into the `render_block` filter for block themes (FSE). The
form is shown only when the product is out of stock.
### What if my theme or template does not fire WooCommerce hooks?
Use the shortcode `[wt_waitlist product_id="123"]` — it works everywhere, from page
builders to custom single product templates.
### How many emails are sent at once?
Action Scheduler processes batches of 50 subscribers per tick. For a product with
1000 subscribers we queue 20 batches, each processed asynchronously, without blocking
the PHP request.
### Do emails go through my WP Mail configuration?
Yes. We use `wp_mail()` — if you have WP Mail SMTP, SendGrid, Amazon SES etc. configured,
the mail travels through them. The plugin does not hardcode any provider.
### What happens to the data after uninstalling the plugin?
The `uninstall.php` file drops the tables and deletes the options. Clean. If you
deactivate without deleting, the data stays — you can reactivate without losing
subscriptions.
### GDPR compliance?
The plugin stores anonymized IPs (last octet zeroed), consent timestamp and user
agent. It integrates with WordPress Privacy Tools — a customer can request data
export or deletion through the standard WordPress flow.
### The signup form does not appear on my product page. What now?
First check whether the product is actually out of stock — the form replaces the**
Add to cart** button only when stock is zero (or the variation is unavailable).
If the product is out of stock and the form still does not appear, your theme likely
uses a custom single-product template that bypasses the standard WooCommerce hooks.
Drop the shortcode `[wt_waitlist product_id="123"]` directly into the product description
or template. The shortcode also works inside page builders (Elementor, Bricks, Divi).
### Customers submit the form but no notification email arrives.
Open **WT Waitlist Settings** and click **Send test email to admin**. If the test
email arrives — `wp_mail()` works and notifications will be delivered as soon as
the product returns to stock (give Action Scheduler 1–2 minutes to process the batch).
If the test email does **not** arrive, the problem is on your mail pipeline, not
on the plugin. Install the free **WP Mail SMTP** plugin and route mail through a
transactional provider (SMTP2GO, Brevo, SendGrid, Amazon SES). Shared hosting often
blocks `mail()` silently.
### How do I check whether stock notifications are queued?
Open **WooCommerce Status Scheduled Actions** and filter by hook `wt_waitlist_*`.
You will see pending and completed jobs with timestamps. If nothing appears after
a stock change, check the **System status** panel inside **WT Waitlist Settings**—
it shows whether Action Scheduler is available and how many `wt_waitlist_*` jobs
are pending.
### Something is broken and I want to send a support ticket.
Open **WT Waitlist Settings**, click **Copy diagnostic info** and paste the resulting
block into your email to support. It includes plugin/WP/WC/PHP versions, theme info,
table state, subscription counts, recent email log, Action Scheduler status and
a sample of out-of-stock products with their purchasable / backorders state — everything
we need to diagnose the issue without going back and forth.
### I use Flatsome / Avada / Enfold / Porto and the form does not appear.
Themes with custom product-page templates (Flatsome UX Builder, Avada Builder, Enfold
templates, Porto) often replace the standard WooCommerce single-product template,
which bypasses the hooks WT Waitlist uses to attach the signup form. As of **v1.0.3**
we ship multiple compatibility layers, including a `wp_footer` JS DOM-injection
fallback that should handle most of these themes automatically. The plugin also
detects these themes and shows a compatibility note inside **WT Waitlist Settings
System status**.
If the form still does not show:
* In Flatsome, switch the product template to **Default** in _Flatsome Theme Options
WooCommerce Product Page_.
* Or place the shortcode `[wt_waitlist product_id="123"]` directly inside the product
description / UX block / Custom HTML block.
### My product is marked out of stock but customers can still add it to the cart, and the waitlist form does not appear.
That means the product has **backorders enabled** (Product Inventory Allow backorders).
WooCommerce treats it as purchasable even though `is_in_stock()` returns false —
and your customers see the standard “Add to cart” button alongside a backorder notice.
WT Waitlist still renders its signup form for such products (so both signup paths
coexist), but if the form is missing on a backorder-allowed product, check the **
Sample out-of-stock products** section inside the diagnostic info (button **Copy
diagnostic info**) — it lists `is_purchasable / backorders_allowed / subscribers`
per OOS product so you can see exactly how WooCommerce treats each item.

## ცვლილებები
#### 1.0.4
* **Fix: signup form rendered twice** on most themes. Two of the rendering layers
shared one callback that did not check the “already rendered” guard, so the form
appeared duplicated. Resolved — the form now renders exactly once.
* **Fix: signup form not appearing on variable products** when a selected variation
is out of stock or on backorder. The variation-aware JavaScript relied on `is_in_stock`,
which is `true` for `onbackorder` variations. The plugin now tags each variation
server-side (`woocommerce_available_variation`) with an explicit waitlist flag,
so the form shows correctly for every non-`instock` variation.
* New: **Editable signup form text** — the form heading, description, button label
and success message can now be customized under WT Waitlist Settings “Signup
form text”. Leave a field empty to keep the built-in translated default.
* i18n: translated the last two hardcoded Polish fallback strings in the frontend
script (connection / generic error messages).
#### 1.0.3
* **Fix: signup form was not appearing on backorder-allowed products.** WooCommerce
has three stock statuses — `instock`, `outofstock` and `onbackorder` — and `WC_Product::
is_in_stock()` returns `true` for both `instock` and `onbackorder`. The previous
version’s check `!is_in_stock()` therefore skipped backorder products entirely.
We now use `get_stock_status() !== 'instock'` so the form is rendered (and accepts
signups) for both true-OOS and backorder products. This is the primary fix in
1.0.3 — strongly recommended for any store using WooCommerce backorders.
* New: **Two additional rendering layers for theme compatibility** — `woocommerce_after_single_product_summary`(
Layer 4) and `wp_footer` + JS DOM injection (Layer 5). Fixes “signup form does
not appear” on themes that bypass the standard WooCommerce summary hooks (Flatsome
UX Builder, Avada Builder, Enfold, Porto and similar page-builder driven themes).
* New: **Sample out-of-stock products** section in System status — for the first
5 OOS products shows `is_in_stock / is_purchasable / backorders_allowed / subscribers`
so backorder vs. waitlist conflicts are immediately visible.
* New: **Theme compatibility hints** — System status now reports the active theme
template slug and surfaces a known-incompatibility note for Flatsome / Avada /
Enfold / Porto.
* i18n: **All user-facing strings translated to English** (admin Settings labels,
signup form, error messages, email templates, unsubscribe page, admin list table).
Polish-only release is over — the plugin now ships in English by default.
* Docs: new FAQ entries covering Flatsome/builder-theme rendering and backorder-
vs-waitlist behavior.
#### 1.0.2
* New: **System status** panel inside WT Waitlist Settings — versions, DB tables,
subscription counts, Action Scheduler state and recent email log at a glance.
* New: **Send test email to admin** button — one-click verification that `wp_mail()`
works on this site (surfaces PHPMailer error string on failure).
* New: **Copy diagnostic info** button — generates a paste-ready support snippet
so you do not have to copy values by hand.
* New: **Quick start** panel at the top of the settings page explaining the out-
of-stock form Action Scheduler email flow in four lines.
* Tweak: fixed `WT_WAITLIST_VERSION` constant that still reported `0.1.0` in cached
environments.
#### 1.0.1
* Fix: replaced inline `
