详情介绍:
Plogins Waitlist adds a waitlist form to out-of-stock WooCommerce products. A shopper enters their email, and when you set the product back to "In stock", Plogins Waitlist emails everyone waiting through your site's own WordPress mailer. There is no external service, no account to sign up for, and nothing leaves your database.
The form is rendered in PHP on the single-product summary, where it sits in the normal page flow rather than being injected after load, so it does not shift surrounding content. Submitting it runs a small vanilla-JavaScript
fetch request loaded with defer in the footer; the plugin adds no jQuery of its own. On variable products it hooks into WooCommerce's existing variation script so the form only appears once an unavailable variation is selected.
Accessibility was a first-class concern rather than an afterthought. The email field carries a visually hidden label, consent is a real required checkbox, and the success/error message is announced through an aria-live region while the form reports aria-busy during submission.
Subscriber data lives in a single {prefix}_restock_waitlist table that the plugin creates and version-tracks. A restock queues the mailing and sends it in batches on WordPress's own cron, so the request that changed the stock is not held open while the emails go out. Uninstalling drops the table, removes the plugin's options and unschedules any batch still waiting, leaving nothing behind.

Does Plogins Waitlist require WooCommerce?
Yes. Plogins Waitlist is a WooCommerce extension and requires WooCommerce 8.0 or later. It will show an admin notice and stay inactive if WooCommerce is missing or out of date.
How are notifications sent?
When WooCommerce sets a product's stock status to instock, Plogins Waitlist queues the mailing rather than sending it inside that request. WordPress cron then walks the pending subscribers for that product (and its parent, for variations) in batches of 50, oldest signup first, emailing each one with the Back in stock (Waitlist) WooCommerce email, which goes through your site's own WordPress mailer. Edit its subject, heading, extra content and format, or switch it off, under WooCommerce > Settings > Emails; the template can be overridden in yourtheme/woocommerce/emails/waitlist-restock.php. Subscribers who are emailed successfully are marked as notified so they are not contacted twice. Filter plogins_waitlist_notify_batch_size to change the batch size.
Does it work with variable products?
Yes. Choose options in the standard WooCommerce variation form first. When the selected variation is out of stock or on backorder, the waitlist form appears and the subscription is stored for that specific variation.
Can guests join the waitlist?
Yes by default. You can restrict signups to logged-in customers by unchecking Allow guest subscriptions in WooCommerce > Plogins Waitlist.
Can customers manage waitlists in My Account?
Yes. Logged-in customers see a Waitlists tab under My Account with active subscriptions, current stock status, and a button to leave each list.
Does this comply with GDPR / consent requirements?
Every signup requires the shopper to tick an explicit consent checkbox before they can join the waitlist; the form will not submit without it. When a privacy policy page is set under Settings > Privacy, the consent label links to it. Every restock email carries a signed "Leave this waitlist" link (and a List-Unsubscribe header for mail clients) that removes the signup without a login; the link does not reveal whether an address is on any list. Subscriber emails are stored only in a custom table in your own WordPress database and are never sent to any external service. You are responsible for the wording of your consent label and your site's privacy policy.
Can I export the subscriber list?
Yes. From WooCommerce > Plogins Waitlist > Subscribers you can view subscribers, filter by product, and export the list as CSV.
Does the form reload the page on submit?
No. The form is submitted with a vanilla-JavaScript fetch call and the result is announced in an aria-live region, so the page stays put. Plogins Waitlist loads no jQuery for this; on variable products it does rely on WooCommerce's own variation script to know which variation is selected.
Does it work with Shortlist and Rezervo?
Yes. Shortlist shows this sign-up form on out-of-stock items on the wishlist, switched in the Shortlist settings. Rezervo takes pre-order products and variations off the waitlist with no setting, so a pre-order never shows a second sign-up form. Developers can do the same with the plogins_waitlist_accepts_subscriptions filter.
Does this plugin work on WordPress Multisite?
Yes. This plugin is compatible with WordPress Multisite. Network activate it or activate it on individual sites; each site keeps its own settings and data.
更新日志:
1.1.10
- Fixed: a shop manager could open the Waitlist settings screen but every save failed with "Sorry, you are not allowed to manage options for this site." Anyone who can manage WooCommerce can now save it.
- Fixed: deleting the plugin on a multisite network now removes the waitlist table, settings and queued mailings on every site, not only the main one.
- Fixed: deleting the plugin no longer drops the waitlist table while another installed plugin that adds subscribers to it is still on the site; the table is removed with whichever of the two is deleted last.
- Fixed: the site could fatal ("Unknown named parameter") when another Plogins plugin with an older copy of the shared library was active. Plogins Waitlist's bundled copy now lives under its own namespace.
- The Shortlist line under Ecosystem integrations says the wishlist shows this waitlist form on out-of-stock items, and links to the plugin search on the Add Plugins screen when Shortlist is not installed.
- Added:
plogins_waitlist_accepts_subscriptions, a filter deciding whether a product or variation takes waitlist signups. Returning false removes the form, the per-variation flag and the signup for it. Rezervo uses it so a pre-order product shows its Pre-order button and no second "Notify me" form.
- Security (low): the waitlist signup accepted the id of a draft, private or password-protected product, so restocking a product before publishing it could email its name and link to an address someone had signed up for it. Signups now need a product a visitor can see.
- Settings: a new Ecosystem integrations section says whether Shortlist is active and what the two plugins do together. It changes no behaviour.
- The Upgrade to PRO links open the pricing page in the admin's language where plogins.com has one, and tell plogins.com which plugin the visit came from (utm_source, utm_medium and utm_campaign in the link). Nothing is sent from your site.
- Readme: the Polski for WooCommerce cross-link no longer calls it "Polish-market compliance"; it describes tools for Polish-market rules that do not make a shop compliant on their own.
- The default closing line of the restock email now points to the leave link instead of telling guests to ignore the email. A closing line you saved yourself is unchanged.
- New: the restock email is a WooCommerce email (store header and footer, product name, image and link) with an HTML and a plain-text version, editable or switchable off under WooCommerce > Settings > Emails > Back in stock (Waitlist). A subject saved on the plugin's own settings screen stays the default until one is saved there.
- New: every restock email has a "Leave this waitlist" link that works without a login, plus
List-Unsubscribeand one-clickList-Unsubscribe-Postheaders. Opening the link asks for confirmation, so mail scanners that open links cannot remove anyone. The link is signed per signup and rate limited, and an invalid or used link never says whether an address is subscribed. - New: the consent label links to the site's privacy policy when one is set.
- Improved: back-in-stock emails are now sent in batches through WooCommerce Action Scheduler, so each batch is visible with its log under WooCommerce > Status > Scheduled Actions. Sites where Action Scheduler is not loaded keep using WP-Cron. Deactivating or deleting the plugin clears queued batches from both.
- Security (low): My Account > Waitlists matched signups by the account email as well as the account itself. WooCommerce does not verify an account email, so any logged-in customer could change theirs to a guest's address and then see and remove that guest's pending waitlist signups. Only signups made while logged in to that account show there now. A signup made as a guest before registering no longer appears in My Account; it still gets its restock email.
- Fixed: the "Leave waitlist" button in My Account did nothing. Its script was never loaded on that tab, and the request it would have sent was refused because the handler read the security token from a field the script does not send.
- Fixed: on variable products in a store not running in English, the form never appeared for an out-of-stock variation, because the check looked for the English words "out of stock". A variation on backorder never showed the form in any language. The plugin now tells the page which variations take signups, using the same rule as the signup itself.
- Fixed: the
[restock_waitlist]shortcode and the Elementor widget, placed anywhere except a product page, printed a form without its script. Submitting it reloaded the page, signed nobody up and put the email address in the URL.
- The sidebar upgrade promo now follows the same dismissal as the banner. Dismissing the banner used to leave a full-height advert on the settings screen for good, which is not what the WordPress.org guideline on upgrade prompts means by used with moderation.
- Fixed: the plugin logged
Warning: Class "Waitlist\Plugin" not foundon every request on any site with WP_DEBUG on. A compatibility alias kept for Plogins Waitlist PRO 1.0.2 and older was declared before the plugin's autoloader was registered, so PHP could not find the class it was aliasing. The alias now sits below the autoloader, which also means it is finally declared: for the whole time it was above, it failed and gave those old PRO versions nothing. - Copy: the "How are notifications sent?" answer still described the email leaving the moment WooCommerce sets the stock status. It has been queued and sent in batches on WP-Cron since 1.0.25, which is what the rest of the readme says; the answer now says it too.
- Fixed: deactivating the plugin could throw a fatal error, and leave it impossible to switch off, on a site also running Plogins Waitlist PRO 1.0.12 or older. The deactivation routine read the name of its scheduled job off a class those PRO versions also supply, in a copy that does not carry that name. The name is now written out in full and the routine loads nothing.
- Fixed: deleting the plugin without deactivating it first left its queued mailing scheduled.
wp plugin deleteremoves an active plugin without deactivating it, so uninstall now unschedules the job in the same way deactivation does. - Added:
plogins_waitlist_should_notify, a filter deciding whether a restock mails the people waiting for that product. Returning false skips the mailing and leaves those subscribers pending. Plogins Waitlist PRO applies its category segmentation through it instead of taking the mailing over. - Note: if you run Plogins Waitlist PRO, update it to 1.0.14 or later at the same time. Older PRO versions remove this plugin's mailing callback on every restock and send the emails themselves, one at a time, inside the request that changed the stock. PRO 1.0.14 hands that work back to the queue here, and requires this version.
- Fixed: the CSV export could leave subscribers out of the file without saying so. It read the list in chunks by offset, over the same rows a queued restock mailing marks as notified while it runs, so every row that left the set took another row with it. The export now walks by a cursor on a stable key, which cannot skip or repeat. Rows come out oldest first; the list on screen is unchanged.
- Fixed: a queued batch that could not run ended the mailing for good. If the product could not be loaded on that cron tick, or the waitlist had just been switched off, the front of the list was mailed and the rest was left neither mailed nor cleared. The same batch is now retried up to three times, five minutes apart, before the mailing is abandoned.
- Fixed: queued mailings survived deactivating the plugin. They are now unscheduled with the plugin, whichever batch they were up to.
- Fixed: "Remove" on the subscriber list threw you back to page one of an unfiltered list. It now returns to the page, product filter and search you removed from.
- Fixed: a personal-data export request (Tools > Export Personal Data) hit a fatal error on the "Subscribed At" row, which tried to print a date object as a string. Static analysis had been reporting it; the analysis now runs over the shared engine directory too, which had been outside both it and the coding-standards check.
- Changed: a pending-subscriber query that names no limit of its own now reads at most 5000 rows (filter
plogins_waitlist_pending_query_limit), and the waitlist list on a customer's account page at most 200. Neither had a ceiling before.
- Fixed: restocking a product no longer sends the waitlist emails inside the request that changed the stock. A product save, a REST update or an order going through used to wait for one email per waiting shopper. The mailing is now queued and sent in batches of 50 (filter
plogins_waitlist_notify_batch_size), in the same order, to the same people. - Fixed: the Subscribers screen read the whole table on every load. It is now paged at 50 rows (filter
plogins_waitlist_subscribers_per_page), the summary counts come from the database so they describe the whole list, and the CSV export streams in chunks instead of loading every row first.
- Fixed: the PRO upgrade promo kept selling to people who had already bought the paid edition. Only the banner could be dismissed, so the sidebar promo and the locked feature cards followed a paying customer around for good. The promo now checks whether the paid edition is active and steps aside when it is.
- Fixed: arrow glyphs in the admin menu paths, and in the strings handed to translators. An arrow inside a translatable string makes the glyph every translator's problem and changes the layout in any locale that drops it.
- Changed: the PRO feature cards printed an arrow glyph in menu paths where the rest of the plugin and the documentation use a plain ">". Same navigation, one character that renders everywhere.
- Fixed: deleting the plugin left the per-user "dismiss" flag from the PRO notice in the database. Uninstall now removes it for every user, not just the one who dismissed it.
- Eleven strings in the privacy exporter and eraser (the data a shop hands over or deletes on a GDPR request) were tagged with the plugin's old text domain, left over from the rename away from Restock. WordPress looked them up under a name no translation file uses, so they could never appear in any language but English. They now use the plugin's own text domain.
- The placeholder in "Product #%d" had no note for translators explaining what the number is.
- "Tested up to" was declared in the plugin header as well as the readme. Only the readme is read by WordPress.org, and declaring it twice is a way to publish a compatibility claim nobody intended.
- The translation template was regenerated. 16 strings added to the plugin since the template was last built were missing from it, so no translator could reach them in any language, and 2 strings the plugin no longer uses have been dropped. Nothing you see changes; what a translator can see does.
- Fixed: the plugin reported an older version number internally than the one it was released under. That number versions the stylesheets and scripts the admin screen loads, so a browser holding the previous files kept them after an update instead of fetching the corrected ones.
- Fixed: the package no longer ships its own translation files. WordPress.org builds language packs from translate.wordpress.org, and a bundled catalogue shadows that pack, so a translation corrected upstream could not reach you until the next release. Your language now comes from the language pack, which is the copy that stays current.
- Declared compatibility with WooCommerce 11.0.
- Fixed the PRO promo on the settings screen quoting a price in PLN. PRO is priced and charged in EUR, so an admin on a Polish site was shown a zloty amount and then billed in euro, and the zloty figure was a fixed conversion that drifted from the real charge as the rate moved. The promo now shows the euro price that is actually taken.
- Fix: corrected the PRO pricing line. Subscriptions are priced and charged in EUR. An earlier wording claimed a different currency was offered at the payment step.
- Fix: turning off "Show form on product page" now only stops the automatic placement. The [restock_waitlist] shortcode and the Elementor widget keep working, and signups made through them are accepted instead of failing with "Waitlist is unavailable for this product".
- Fix: ticking "Show heading" or "Show intro text" while leaving the text field blank now shows the wording from the greyed placeholder, as the field help promises, instead of showing nothing.
- Fix: a variation coming back in stock now notifies the people waiting for it. WooCommerce fires a separate action for variations, and only the product-level one was listened to, so a signup made on one size or colour never triggered an email.
- Translations: completed Polish, German and Spanish for the PRO upgrade panel.
- Declared compatibility with WooCommerce 10.9.
- Security: prevent CSV formula injection in the subscriber export; a crafted signup email can no longer execute as a spreadsheet formula when the file is opened.
- Translation quality pass: corrected Polish, German and Spanish (product names kept in English, legal withdrawal terminology, WooCommerce glossary and grammar fixes).
- Documentation: readme links are now labelled links.
- Shortened display name (dropped the Plogins prefix; slug unchanged).
- Fixed low-contrast headings on the admin settings screen under an OS dark-mode preference.
- Added a Free vs PRO overview to the readme.
- Added bundled Polish, German and Spanish translations for the plugin interface.
- Internal cleanup: unified the internal code identity to Waitlist (was Restock). No change to your settings or data; legacy aliases keep older PRO builds working during the update.
- Added a settings-screen overview of upcoming PRO features.
- First stable release.
- Docs: added a "You may also like" section linking the other free WPPoland WooCommerce plugins. No functional changes.
- New: optional social-proof line above the form showing how many shoppers are already waiting for a product ("12 shoppers are already waiting for this item."). Singular/plural aware, fully customisable text with a {count} placeholder, and hidden when nobody is waiting.
- New: remove a subscriber directly from the admin Subscribers list (nonce-protected, with confirmation).
- New: Elementor widget for the back-in-stock waitlist form, so it can be placed with the Elementor editor. Self-guarded: loads only when Elementor is active.
- Fix the text domain on three admin help strings so it matches the plugin slug.
- Renamed to Plogins Waitlist for WooCommerce for a distinct, non-generic directory name. No functional changes.
- New: WooCommerce My Account Waitlists tab with stock status and leave-waitlist action.
- New: variation-aware waitlist signups on variable products (form shows after an out-of-stock variation is selected).
- New: settings for My Account menu label, variation prompt, and unsubscribe confirmation message.
- New:
[restock_waitlist]shortcode to place the waitlist form manually (optionalidattribute to target a specific product). - New: optional form heading and intro text, configurable from the settings page.
- New: editable on-screen form messages (success, invalid email, missing consent, login required).
- Improved: the settings page now exposes every form label, message, and email text the engine supports, instead of relying on hardcoded defaults.
- Improved: empty optional settings now correctly fall back to the built-in defaults.
- Initial release.
