Duplicate Killer – Prevent Duplicate Form Submissions
Duplicate Killer – Block Duplicate Form Submissions in WordPress. WooCommerce – Prevent Accidental Duplicate Orders Duplicate Killer also protects WooCommerce Classic Checkout from accidental duplicate orders. WooCommerce already disables the “Place order” button, but duplicate orders can still happen when: Checkout is slow Payment gateways lag or retry Customers refresh the page Multiple tabs are used Network requests are retried Duplicate Killer FREE adds lightweight server-side duplicate protection for WooCommerce Classic Checkout. If the same customer attempts to submit an identical order within 60 seconds, the duplicate is blocked and a validation message is shown. !!! No changes to your checkout design. No impact on performance. No additional configuration required. If your forms receive the same email address multiple times, fake leads, or repeated submissions, this plugin blocks them instantly. Choose which fields must be unique (email, phone, text) and block duplicate entries automatically — without changing your form design or user experience. Duplicate Killer works silently in the background and integrates seamlessly with popular WordPress form plugins and page builders. Cross-Form Duplicate Protection (PRO) Duplicate Killer PRO introduces Cross-Form Duplicate Protection. This feature allows duplicate detection across multiple forms on your website. For example, if a user submits the same email address in two different forms, Duplicate Killer PRO can detect the duplicate and block the second submission. This is useful when: – multiple contact forms exist across different pages – marketing forms collect the same email address – lead capture forms should only allow one submission per user – different form plugins are used on the same site This feature is available in Duplicate Killer PRO. Free: In the free version, duplicate protection can be enabled for one form per supported plugin. PRO: Duplicate Killer PRO enables multi-form protection with individual rules and messages per form.

WooCommerce PRO adds: – Checkout Blocks (Store API) support – Configurable lock window (30–300 seconds) – Advanced fingerprint controls (phone, shipping, IP, customer ID) – Order linking (direct link to matching WooCommerce order) – Gateway breakdown (Stripe, PayPal, COD, etc.) – Trends dashboard (Last 24h, 7 days, 14 days) – CSV export for audits and support teams – Detailed analytics (top products, domains, checkout types, IPs) – Designed for real-world edge cases such as slow hosting, gateway retries, reverse proxies and unstable mobile networks. When to use Duplicate Killer Use this plugin if you receive repeated submissions with the same email, phone number or text values. If you only need basic spam protection, a CAPTCHA plugin may be enough. When should I use Duplicate Killer PRO? Use the PRO version if your site has multiple forms with different purposes — for example a contact form, a registration form and a newsletter signup — and each one needs different duplicate submission rules. Does FREE support WooCommerce Checkout Blocks? No. Checkout Blocks use a different system (Store API) and require the PRO version. What happens if I upgrade to PRO later? All WooCommerce duplicate logs stored in the FREE version are automatically used by PRO analytics. No database migration is required. Does this prevent payment gateway retries? FREE prevents accidental duplicate submissions on Classic Checkout. PRO adds enhanced idempotency handling and deeper gateway analytics.
Form Vibes – Save Contact Form 7 & Elementor Form Entries to Database
Form Vibes saves your contact form submissions to the WordPress database automatically – no configuration needed. Just install and activate, and every form entry from Contact Form 7, Elementor Pro Forms, WPForms, Gravity Forms, Ninja Forms, WS Form, Bricks Builder, Beaver Builder, and Everest Forms is captured and stored safely in your database. Never lose a lead again because of a failed email. View all your form entries in one place, filter them, export them to CSV, sync them to Google Sheets (Pro), and analyze form performance with built-in graphical reports. 🗄️ Why do you need a database plugin for your forms? Contact Form 7 and many other form plugins send submissions by email but do not save entries in the database. If an email fails or lands in spam, the lead is gone forever. And even if your form builder has its own entries screen (like Elementor Pro), your submissions stay scattered across different plugins, each with its own interface and limits. Form Vibes saves entries from all your forms in one central database – every submission is stored safely, searchable, and exportable from a single dashboard, with analytics on top. ✅ One Plugin for All Your Forms Unlike single-purpose plugins that only save Contact Form 7 entries or only Elementor form entries, Form Vibes is a universal form entries manager.
