Any entry added here is checked before a form submission is recorded or sent to anyone.<\/span><\/p>\n<p><b>Blocked IP Addresses: <\/b><span style=\"font-weight: 400;\">Enter one IP address or pattern per line. Use a single address for an exact block or a wildcard to cover a range. For example, 69.89.31.* stops every address in that range. Using *.226 blocks any IP ending in those digits.<\/span><\/p>\n<p><b>Blocked Email Addresses: <\/b><span style=\"font-weight: 400;\">Follows the same logic as IP blocking. One address per line. Entering *@mail.ru shuts out every address from that domain. *@qq.com does the same for that provider.<\/span><\/p>\n<p><b>Spam Email Filter (Regex): <\/b><span style=\"font-weight: 400;\">Write regex patterns here that run against incoming email addresses. Any address matching a pattern gets blocked before the submission goes any further. Add one pattern per line. The extension includes ready-to-use example patterns covering the most common high-spam domains and address structures. Paste them in, and they apply immediately.<\/span><\/p>\n<h2><b>8.0 Frequently Asked Questions<\/b><\/h2>\n<p><b>Q: What is the OpenCart Form Builder extension, and what does it do?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The Knowband <a href=\"https:\/\/www.knowband.com\/opencart-form-survey-builder\">OpenCart Survey Extension<\/a> is a form builder tool that lets OpenCart store owners create unlimited contact forms, surveys, feedback forms, lead generation forms, and registration forms without writing any code. It includes drag and drop form creation, Cloudflare Turnstile spam protection, per-form email setup, auto-responder, Mailchimp and Brevo sync, form submission tracking, and placement control through the Placements tab. Works with OpenCart 3.x.<\/span><\/p>\n<p><b>Q: How do I create a survey in OpenCart using the OpenCart Survey Builder?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Open the extension and click Add New Form. Give the form a title and a slug. Inside the Form tab, add a row, then drop in radio button fields for ratings, dropdowns for categories, and textarea fields for written feedback. Head to the Mail tab to set up the auto-responder, go to the Thank You Page tab to configure the post-submission message, pick the placement in the Placements tab, and turn the form on. No developer needed at any point.<\/span><\/p>\n<p><b>Q: How do I collect customer feedback in OpenCart without a developer?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The <a href=\"https:\/\/www.opencart.com\/index.php?route=marketplace\/extension\/info&amp;extension_id=48549\">OpenCart Survey Builder Plugin,<\/a> also available on OpenCart Marketplace, manages the full feedback collection process from the admin panel. Build the form, go to the Settings tab, and set the Customer Groups to limit visibility, then pick the layout in the Placements tab. Once enabled, all submissions show up in the Form Submissions panel ready for your team to read and respond to.<\/span><\/p>\n<p><b>Q: How do I display forms on product pages in OpenCart?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Go to the Placements tab inside the form. From the Layouts list, pick Product. In the Positions section, tick Content Bottom or Content Top. The form shows up at that position on every product page without any changes to the theme.<\/span><\/p>\n<p><b>Q: Does this OpenCart survey plugin support email notifications?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Yes. Every form carries its own email setup in the Mail tab under the Email to admin sub-tab. The admin notification goes to whichever address you configure and fires as soon as a customer submits. The Auto responder sub-tab handles the customer-facing confirmation. Subject line, body text, and reply-to address are all set per form in the OpenCart Survey Builder using multilingual rich text editors.<\/span><\/p>\n<p><b>Q: How do I build unlimited forms in OpenCart with this OpenCart Survey Extension?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">This OpenCart Survey Extension has no cap on forms, fields, or submissions. Add as many as your store needs, contact forms, product feedback form OpenCart, customer satisfaction survey OpenCart, lead generation forms, registration forms, and post-purchase surveys. Each one runs on its own settings with separate placement rules, email routing, and a dedicated submission log.<\/span><\/p>\n<p><b>Q: What is the easiest way to create a survey in OpenCart?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Open the OpenCart Form Creator, click Add New Form, name it, and set the slug. Use the drag and drop form builder OpenCart interface to pull fields into the layout rows. Set up the email and placement settings, switch the form on, and it goes live. A first-time user with no technical background can go from opening the extension to a live survey in under 15 minutes.<\/span><\/p>\n<p><b>Q: What is the best OpenCart form builder plugin in 2026?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The best OpenCart form builder plugin in 2026 covers form creation, placement, spam filtering, email automation, and submission management from one installation with no developer needed for any of it. This extension covers all of these: drag and drop builder, Cloudflare Turnstile, per-form email and auto-responder, Mailchimp and Brevo integration with field mapping, layout-based placement control, and a full submission management panel with direct reply capability.<\/span><\/p>\n<p><b>Q: How does spam protection work in the OpenCart Form Studio?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Switch Cloudflare Turnstile to Enabled in the General Settings Cloudflare Turnstile tab by entering the Site Key and Secret Key from your Cloudflare account. Once active globally, drag the Cloudflare Turnstile field into any individual form layout. This spam protection form OpenCart approach, blocks bots silently before the submission is recorded. Real customers see no challenge or CAPTCHA. The IP and Email Blacklist adds a second layer for blocking known bad actors by address or domain.<\/span><\/p>\n<p><b>Q: Is the OpenCart Form Builder extension compatible with the latest OpenCart version?<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Yes. This responsive form builder OpenCart extension is compatible with OpenCart 3.x.
