§ 00WordPress + Feedback Formplatform-specific integration guide

Why WordPress developers choose splitforms for feedback form

WordPress contact form plugins (Contact Form 7, WPForms, Fluent Forms) work but add database bloat, update fatigue, and a monthly subscription for features like webhook delivery or advanced spam controls. The feedback form on this page drops into a Custom HTML block — no PHP, no plugin activation, no settings page to configure. Every field POSTs to splitforms as standard form data, so your WordPress admin stays clean. You keep using WordPress for content management and page building while splitforms handles the form pipeline.

§ 00Quick answerPHP · feedback

Yes — this is the shortest safe path for WordPress.

Use the PHP snippet on this page, keep the feedback form fields visible in your WordPress UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the PHP version, then replace YOUR_ACCESS_KEY.

The posted payload contains how would you rate your experience?, what can we do better?, email (optional, for follow-up). Required fields are how would you rate your experience? and what can we do better?.

native wordpress reality

WordPress core has no contact-form feature — every contact form on a WP site is either a plugin (Contact Form 7, WPForms, Gravity Forms, Forminator, Fluent Forms, Ninja Forms) or a custom theme template.

use case fit

Customer feedback is the cheapest product research you have. The form captures NPS / CSAT plus an open comment — and routes negative responses to a Slack channel for same-day triage.

§ 03bCustomer Feedback Form (NPS / CSAT / Open-Ended)template-specific playbook

The reason this feedback form exists.

Webhooks into Slack / Linear / Productboard · NPS detractor triage in minutes.

why it matters

Feedback forms cost almost nothing to ship and pay back disproportionately — every NPS detractor (score 0-6) is a conversation that prevents churn, every promoter (9-10) is a referral or testimonial source. The form is simple: 0-10 rating, an optional comment, and an email. The leverage is in the routing: detractors auto-DM your support lead in Slack within minutes, promoters get a 'mind leaving us a G2 / Trustpilot review?' follow-up, passives go into a digest. Survey tools (SurveyMonkey, Typeform, Hotjar) charge $30-100/mo for the same pattern. The form pattern is 30 lines of HTML.

route the submission
01

Capture rating + comment

Required: 0-10 NPS rating (or 1-5 CSAT for transactional surveys). Optional: comment textarea, email for follow-up. Keep it minimal — long surveys tank completion.

02

Route by score

Webhook branches on score: 0-6 (detractors) DM Slack support channel; 7-8 (passives) go to weekly digest; 9-10 (promoters) trigger a G2 / Trustpilot review-request email.

03

Push to your tools

Detractor comments to Linear / Productboard for product triage. Promoter quotes to a 'testimonials' Notion database for marketing. Raw data to a CSV / BigQuery / dbt warehouse for trend analysis.

§ 03cWordPress production notesnative path · deploy · gotchas

What changes when this feedback form lives in WordPress.

These notes come from the WordPress platform registry and are rendered on this template page so crawlers see the framework-specific answer without opening a separate guide.

without splitforms

WordPress core has no contact-form feature — every contact form on a WP site is either a plugin (Contact Form 7, WPForms, Gravity Forms, Forminator, Fluent Forms, Ninja Forms) or a custom theme template. Plugins add 3-7 database tables, increase TTFB by 50-300ms, and most require a paid SMTP plugin (WP Mail SMTP) on top because shared-host PHP mail() lands in spam. CF7 alone is 1.2MB of JS/CSS loaded on every page. Anti-spam is a separate Akismet subscription ($10/mo for commercial use) or a paid CAPTCHA plugin. Splitforms replaces the plugin: a <form> tag in a Custom HTML block, pointing at our endpoint, with a hidden access_key field. No plugin, no extra DB tables, no SMTP gymnastics.

deploy notes

WordPress runs on shared hosts (Bluehost, Hostinger), managed WP hosts (Kinsta, WP Engine, Pressable), or self-hosted Apache/nginx. The form's POST is cross-origin to splitforms.com, so the host doesn't matter for delivery. Caching plugins (WP Rocket, W3 Total Cache, LiteSpeed Cache) cache the page that hosts the form — that's fine, the form action URL is static. Don't proxy through WP's admin-ajax.php or wp_remote_post — adds latency and re-introduces the SMTP problem. For Multisite, use one access key per site or a shared key with form-name to disambiguate. Headless WP (Next.js/Astro front) doesn't involve PHP at all — use the matching framework's snippet.

WordPress gotcha

WordPress wpautop() mangles your form HTML in posts

If you paste a <form> directly into a Classic Editor post, WordPress's wpautop filter wraps random <p> tags around your inputs and breaks the markup. Use a Custom HTML block (block editor) or a theme template file instead — wpautop doesn't touch those.

WordPress gotcha

Caching plugins (WP Rocket, W3 Total Cache) cache the form page itself

Page caching is fine — your form posts to splitforms.com directly, not a WordPress endpoint, so the cached HTML still works. But if you ever switch to a WP-side handler (e.g. wp_ajax), exclude /contact/ from the page cache or submissions will hit a stale page.

WordPress gotcha

Theme-injected JavaScript can hijack form submission

Some themes (Astra, OceanWP, GeneratePress 'Premium') auto-attach AJAX handlers to every form on the page. Add data-no-ajax="true" or a custom class your theme excludes — or use a Custom HTML block which most themes leave alone.

WordPress gotcha

Cloudflare Bot Fight Mode blocks splitforms responses

If you proxy your WP site through Cloudflare with Bot Fight Mode on, the redirect from splitforms.com → /thanks may be flagged. Whitelist your domain in splitforms's allowed-domains list AND ensure /thanks is reachable without a Cloudflare challenge.

PATTERN A

Pattern A — Custom HTML block (Block Editor / Gutenberg)

Drop a Custom HTML block on any page or post. Survives theme switches and plugin updates. No PHP required, no theme file editing. Reusable Patterns let you save the form once and drop it on every page. Use the same wiring for the feedback form fields on this page.

01<form action="https://splitforms.com/api/submit" method="POST">
02 <input type="hidden" name="access_key" value="YOUR_ACCESS_KEY" />

07 <input type="checkbox" name="botcheck" style="display:none" tabindex="-1" />
08 <p><button type="submit">Send</button></p>
09</form>
PATTERN B

Pattern B — theme template with key from wp-config constant

For developer-managed themes (Bedrock/Sage/classic), define SPLITFORMS_KEY as a constant in wp-config.php and echo it via esc_attr(). Keeps the key out of the theme repo, lets staging and production read different keys via environment. Use the same wiring for the feedback form fields on this page.

01<?php // page-contact.php in your theme ?>
02<form action="https://splitforms.com/api/submit" method="POST">
03 <input type="hidden" name="access_key" value="<?php echo esc_attr( SPLITFORMS_KEY ); ?>" />
04 <input type="hidden" name="redirect" value="<?php echo esc_url( home_url('/thanks') ); ?>" />

§ 06Questions9 answered

Feedback Form on WordPressFAQ.

Direct answers, no marketing fluff. Missing one? Email hello@splitforms.com.

01Does this feedback form work on WordPress?
Yes. The form is plain HTML with a single POST endpoint, so it runs on any WordPress site without server-side code, plugins, or SDKs. Drop the snippet into a WordPress page or component and submissions land in your splitforms dashboard.
02How much does the feedback form cost on WordPress?
Free for 500 submissions per month — no credit card, no trial. Pro is $5/mo for 5,000 submissions, and there's a one-time $59 3-year plan (15,000 submissions/mo for 36 months). The same pricing applies regardless of which framework hosts the form.
03Can I customize the fields?
Yes. The template ships with sensible defaults (how would you rate your experience?, what can we do better?, email (optional, for follow-up)…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.
04How does spam protection work on the feedback form?
A hidden honeypot field catches dumb bots, and a tuned classifier scores the rest. You only see real submissions in your dashboard. No CAPTCHA, no friction for human users — and it works the same on WordPress as on any other framework.
05Can I send the feedback form submissions to Slack or Discord?
Yes. Webhooks are available on Starter and above, with auto-formatted payloads for Slack, Discord, and WhatsApp (via CallMeBot). Or send raw signed JSON to any URL — Zapier, n8n, your own server. Configure in the splitforms dashboard.
06Will it work on a static WordPress site?
Yes — the form posts directly to splitforms from the browser, so no server is involved. Works on Vercel, Netlify, GitHub Pages, Cloudflare Pages, S3, or any plain Apache host.
07Should I use NPS or CSAT?
NPS (0-10) for relationship surveys ('how likely are you to recommend us?') sent quarterly or after major moments. CSAT (1-5) for transactional surveys ('how was this support ticket?') sent right after the interaction. Different questions, different cadences, both common patterns.
08Will I get response bias from a public form?
Yes — open-link feedback skews toward people with strong feelings (positive or negative). For statistically representative measurement, send the survey via email to a random sample of users. The public form catches the heat-of-moment feedback you'd otherwise miss.
09Can I push to Slack / Linear / Productboard?
Yes — webhook the JSON. Slack has incoming webhooks (free); Linear and Productboard accept inbound issue creation via Zapier or native APIs. Detractor comments showing up as a Linear issue with the rating prefilled in the title is a powerful workflow.
