§ 00Hugo + Event RSVPplatform-specific integration guide

Why Hugo developers choose splitforms for event rsvp

Hugo's build speed is legendary, but Hugo sites are static HTML — there's no built-in mechanism to process form submissions. The traditional workaround is Netlify Forms (100 subs/month free) or a third-party API. The event rsvp on this page posts directly from the browser to splitforms with zero Hugo configuration. It works in Hugo themes, shortcodes, and partial templates — just paste the HTML. Because Hugo's output is plain HTML, the form works on any host without a server-side component.

§ 00Quick answerHTML · events

Yes — this is the shortest safe path for Hugo.

Use the HTML snippet on this page, keep the event rsvp fields visible in your Hugo UI, and let splitforms handle delivery, spam filtering, storage, and webhooks.

best implementation

Paste the HTML version, then replace YOUR_ACCESS_KEY.

The posted payload contains your name, email, will you attend?, how many guests are you bringing?, dietary preferences. Required fields are your name, email and will you attend?.

native hugo reality

Hugo is a static site generator — there's no runtime, no /server/api, no way to handle a form POST without an external service.

use case fit

Eventbrite charges 3.7% + $1.79 per ticket. For a free event, fundraiser, or private gathering, the RSVP form does the same job for $0 — and lives on your own domain.

§ 03bEvent RSVP Form (Public / Private Events)template-specific playbook

The reason this event rsvp exists.

Webhooks into Notion / Airtable / Google Sheets · auto .ics calendar invite.

why it matters

Eventbrite, Splash, and Hopin take 3-7% of every paid ticket and charge subscription fees for the white-label option. For free events (fundraisers, private parties, conferences with sponsor-only revenue, weddings), the platform fees are pure waste. The RSVP form captures attending yes/no, guest count, plus-one names, dietary restrictions, and any custom fields (workshop preference for conferences, song requests for weddings). Webhook to a Notion / Airtable / Google Sheet for the running headcount, plus an automatic confirmation email. Final headcount goes to catering 5-7 days out, same as any platform would deliver.

route the submission

Capture attendance and party

Required: attending yes/no, guest count, plus-one names if applicable. Optional: dietary restrictions, song requests, workshop preference, accessibility needs.

Update the running list

Webhook to a Notion / Airtable / Google Sheet that the host references. Each RSVP appends a row; conditional formatting highlights special diets. Real-time headcount without spreadsheet work.

Confirm via email

Auto-respond with confirmation, event details, and a calendar invite (.ics file). Most guests forget the date once they've RSVP'd — calendar adds reduce no-shows by 30-40%.

§ 03cHugo production notesnative path · deploy · gotchas

What changes when this event rsvp lives in Hugo.

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

without splitforms

Hugo is a static site generator — there's no runtime, no /server/api, no way to handle a form POST without an external service. The native paths are: (a) a Cloudflare Worker / Lambda / Cloud Run service handling POST /contact and emailing you (~4 hours of setup, ongoing operation), (b) Netlify Forms (Hugo-on-Netlify only, 100/mo free), or (c) a third-party form backend like Formspree, Basin, or Web3Forms. Hugo's templating shines for the form's HTML — {{ partial }}, {{ .Site.Params }} for the access key, {{< shortcode >}} for Markdown reuse — but the delivery layer is always external. Splitforms is the simplest external option that doesn't require a Cloud Run service.

deploy notes

Hugo deploys to any static host: Vercel, Netlify, Cloudflare Pages, GitHub Pages, S3, Surge, plain Apache/nginx. The form posts cross-origin so the host is irrelevant. Set splitformsKey in hugo.toml under [params] for private repos; for public repos, build with hugo --param splitformsKey=$SPLITFORMS_KEY and read it from CI env. Hugo's local dev server runs on localhost:1313 — add that to splitforms allowed-domains for testing or use a separate dev key. hugo --minify compresses HTML but doesn't touch attribute values — the form works under minification.

Hugo gotcha

Site.Params lookup is case-sensitive in some Hugo versions

If you set splitformsKey in hugo.toml under [params] but reference it as {{ .Site.Params.SplitformsKey }} in the template, recent Hugo versions still resolve it — but Hugo 0.110 and earlier don't. Use the exact case from your config file.

Hugo gotcha

Markdown content stripping eats inline form HTML

If you put a <form> directly in a Markdown content file, Goldmark's HTML sanitizer strips it. Either set markup.goldmark.renderer.unsafe = true in your config, or wrap the form in a shortcode (recommended): {{< contact-form >}}.

Hugo gotcha

absURL filter on the redirect URL adds a trailing slash you don't want

{{ "thanks/" | absURL }} produces https://yoursite.com/thanks/. Hugo's URL filter normalizes trailing slashes per your uglyURLs config — if your /thanks page lives at /thanks.html (uglyURLs=true), the redirect 404s. Hardcode the URL or set relURL consistently.

Hugo gotcha

Hugo modules / theme overrides require partial in your project, not the theme

If you copy contact-form.html into a vendored theme's layouts/partials/, your changes get overwritten on the next theme update. Always put custom partials in your project's own layouts/partials/ — Hugo's lookup chain prefers project over theme automatically.

PATTERN A

Pattern A — partial in `layouts/partials/contact-form.html`

Reusable partial called from any template with {{ partial "contact-form.html" . }}. Pulls the access key from Site.Params.splitformsKey. Project-level partials override theme partials automatically. Use the same wiring for the event rsvp fields on this page.

pattern-a.htmlhtml8 lines

01{{/* layouts/partials/contact-form.html */}}
02<form action="https://splitforms.com/api/submit" method="POST">
03  <input type="hidden" name="access_key" value="{{ .Site.Params.splitformsKey }}" />
04  <input type="hidden" name="redirect"   value="{{ "thanks/" | absURL }}" />
05  <input name="email" type="email" required />
06  <textarea name="message" required></textarea>
07  <button type="submit">Send</button>
08</form>

PATTERN B

Pattern B — shortcode usable from Markdown content

Save as layouts/shortcodes/contact-form.html. Now writers can drop {{< contact-form >}} (with optional redirect="…" arg) directly into any .md file. Eliminates the need to switch to template editing for one-off forms. Use the same wiring for the event rsvp fields on this page.

§ 06Questions9 answered

Event RSVP on Hugo — FAQ.

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

01Does this event rsvp work on Hugo?

Yes. The form is plain HTML with a single POST endpoint, so it runs on any Hugo site without server-side code, plugins, or SDKs. Drop the snippet into a Hugo page or component and submissions land in your splitforms dashboard.

02How much does the event rsvp cost on Hugo?

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 (your name, email, will you attend?, how many guests are you bringing?…) — add, remove, or rename any of them. Splitforms accepts whatever fields you POST.

04How does spam protection work on the event rsvp?

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 Hugo as on any other framework.

05Can I send the event rsvp 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 Hugo 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.

07Why not just use Eventbrite or Splash?

For free events, both charge subscription fees ($30-100/mo for white-label) plus per-ticket fees. The form costs $0, lives on your own domain (which matters for weddings and brand events), and the data is yours — not licensed inside their platform.

08Can I send a calendar invite (.ics) automatically?

Yes — generate an .ics file and attach to the auto-responder. Webhook to a Zapier / Make automation that crafts the .ics with event title, date, location, and notes. Most email clients render the attachment as 'add to calendar' inline.

09How do I handle plus-ones?

Add 'plus-one yes/no' and a name field that appears conditionally. For weddings, the 'plus-one allowed' is invitation-specific — capture invitation code on the form, and the webhook validates whether that invite includes a plus-one before accepting the second name.
