We’re going to create a contact kind with Subsequent.js and Netlify that shows a affirmation display screen and options enhanced spam detection.

Subsequent.js is a robust React framework for creating performant React functions that scale. By integrating a Subsequent.js website with Netlify’s know-how, we are able to shortly get a working contact kind up and working with out having to write down any server-side code.

Not solely is it a comparatively quick course of to arrange types to be processed by Netlify, however it’s additionally free to get began (with as much as 100 free submissions/per website hosted on Netlify). Kind submissions mechanically undergo Netlify’s built-in spam filter which makes use of Akismet and there are additionally choices that may be configured to extend the extent of spam detection.

Creating the contact kind

Inside the Subsequent.js software we must always create a ContactForm element to render the contact kind inside the contact web page. Should you’d like for this kind to render at /contact, then the ContactForm element beneath with labels and enter fields needs to be used throughout the pages/contact.js file.

const ContactForm = (
  <kind
    identify="contact-form"
    technique="POST"
    motion="contact/?success=true"
  >
    <label htmlFor="identify">Title *</label>
    <enter
      id="identify"
      identify="identify"
      required
      sort="textual content"
    />
    <label htmlFor="firm">Firm *</label>
    <enter id="firm" identify="firm" required sort="textual content" />
    <label htmlFor="electronic mail">E-mail Handle *</label>
    <enter id="electronic mail" sort="electronic mail" identify="electronic mail" required />
    <label htmlFor="message">Message *</label>
    <textarea id="message" identify="message" required></textarea>
    <button sort="submit">Submit</button>
  </kind>
);

The above markup is required to render a kind with a area for Title, Firm, E mail deal with and message with a submit button. When submitting the shape, primarily based on the worth of the shape’s motion, it ought to redirect to contact/?success=true from /contact. Proper now there may be not but a distinction between the web page’s look with and with out the success question parameter, however we are going to replace that later.

Our Contact.js file appears like this up to now:

import React from "react";
const ContactPage = () => {
 const ContactForm = (/* code in above code pattern*/)
 
 return (
   <div>
     <h1>Contact Us</h1>
     {ContactForm}
   </div>
 );
};
 
export default ContactPage;

Now that we’ve got the fundamental kind arrange, the actual magic will occur after we add further data for Netlify to auto-recognize the shape throughout future website deployments. To perform this we must always replace the shape to have the attribute data-netlify="true" and a hidden enter area that accommodates the identify of our contact kind. In Netlify, as soon as we navigate to our website within the dashboard after which click on on the “types” tab  we will view our kind responses primarily based on the identify that we’ve put in our hidden area. It’s necessary that when you have a number of types inside a website that they’ve distinctive names in order that they’re recorded correctly in Netlify.

<kind
  technique="POST"
  identify="contact-form"
  motion="contact/?success=true"
  data-netlify="true"
>
<enter sort="hidden" identify="form-name" worth="contact-form" />

After efficiently deploying the location to Netlify with the data-netlify attribute and the form-name area  then we are able to go to the deployed model of the location and fill out the shape. Upon submitting the shape and navigating to https://app.netlify.com/sites/site-name/forms (the place site-name is the identify of your website) then our most up-to-date kind submission ought to seem if we’ve got efficiently arrange the shape. 

Redirect to affirmation display screen 

So as to enhance the person expertise, we must always add some logic to redirect to a affirmation display screen on kind submission when the URL modifications to /contact/?success=true. There’s additionally the choice to redirect to a wholly totally different web page because the motion when the shape is submitted however utilizing question params we are able to obtain one thing related with the Subsequent Router. We are able to accomplish this by creating a brand new variable to find out if the affirmation display screen or the shape needs to be seen primarily based on the question parameter. The following/router which is imported with import { useRouter } from "subsequent/router"; can be utilized to retrieve the present question params. 

const router = useRouter();  
const confirmationScreenVisible = router.question?.success && router.question.success === "true";

In our case, the affirmation display screen and kind can by no means be seen on the similar time; due to this fact, the next assertion can be utilized to find out if the shape is seen or not.

const formVisible = !confirmationScreenVisible; 

To present customers the choice to resubmit the shape, we are able to add a button to the affirmation display screen to reset the shape by clearing the question params. Utilizing router.change (as a substitute of router.push) not solely updates the web page however replaces the present web page within the historical past to the model with out question params. 

<button onClick={() => router.change("/contact", undefined, { shallow: true })}> Submit One other Response </button>

We are able to then conditionally render the shape primarily based on whether or not or not the shape is seen with:

{formVisible ? ContactForm : ConfirmationMessage}

Placing all of it collectively, we are able to use the next code to conditionally render the shape primarily based on the question params (that are up to date when the shape is submitted):

import React, { useState } from "react";
import { useRouter } from "subsequent/router";
 
const ContactPage = () => {
 const [submitterName, setSubmitterName] = useState("");
 const router = useRouter();
 const confirmationScreenVisible =
   router.question?.success && router.question.success === "true";
 const formVisible = !confirmationScreenVisible;
 
 const ConfirmationMessage = (
   <React.Fragment>
     <p>
       Thanks for submitting this kind. Somebody ought to get again to you inside 24-48 hours.
     </p>
 
     <button onClick={() => router.change("/contact", undefined, { shallow: true })}> Submit One other Response </button>
   </React.Fragment>
 );
 
 const ContactForm = (/* code in first code instance */);
 
 return (
   <div>
     <h1>Contact Us</h1>
{formVisible ? ContactForm : ConfirmationMessage}
   </div>
 );
};
 
export default ContactPage;

Including a hidden bot area

Now that the core performance of our kind is working, we are able to add further spam detection to our kind along with the bottom spam detection as a result of Akismet is included with all Netlify Varieties by default. We are able to allow this by including data-netlify-honeypot="bot-field" to our kind.

<kind
  className="container"
  technique="POST"
  identify="contact-form"
  motion="contact/?success=true"
  data-netlify="true"
  data-netlify-honeypot="bot-field"
>

We additionally must create a brand new hidden paragraph that accommodates a label named bot-field that accommodates the enter. This area is “seen” to bots, however not people. When this honeypot kind area is crammed, Netlify detects a bot after which the submission is flagged as spam.

<p hidden>
  <label>
    Don’t fill this out: <enter identify="bot-field" />
  </label>
</p>

Additional customizations

  • We might discover one other spam prevention possibility that Netlify helps by including reCAPTCHA 2 to a Netlify kind.
  • We might replace the shape to permit uploaded information with enter <enter sort="file">.
  • We might arrange notifications for kind submissions. That occurs over at https://app.netlify.com/sites/[your-site-name]/settings/forms the place we are able to embrace a customized topic area (which will be hidden) for electronic mail notifications.

Full code

The code for the complete website code is accessible over at GitHub.

 Bonus

The next code consists of all the things we coated in addition to the logic for setting a customized topic line with what was submitted within the identify area.

import React, { useState } from "react";
import { useRouter } from "subsequent/router";
 
const ContactPage = () => {
 const [submitterName, setSubmitterName] = useState("");
 const router = useRouter();
 const confirmationScreenVisible =
   router.question?.success && router.question.success === "true";
 const formVisible = !confirmationScreenVisible;
 
 const ConfirmationMessage = (
   <React.Fragment>
     <p>
       Thanks for submitting this kind. Somebody ought to get again to you
       inside 24-48 hours.
     </p>
 
     <button onClick={() => router.change("/contact", undefined, { shallow: true })}> Submit One other Response </button>
   </React.Fragment>
 );
 
 const ContactForm = (
   <kind
     className="container"
     technique="POST"
     identify="contact-form"
     motion="contact/?success=true"
     data-netlify="true"
     data-netlify-honeypot="bot-field"
   >
     <enter
       sort="hidden"
       identify="topic"
       worth={`You've got received mail from ${submitterName}`}
     />
     <enter sort="hidden" identify="form-name" worth="contact-form" />
     <p hidden>
       <label>
         Don’t fill this out: <enter identify="bot-field" />
       </label>
     </p>
 
     <label htmlFor="identify">Title *</label>
     <enter
       id="identify"
       identify="identify"
       required
       onChange={(e) => setSubmitterName(e.goal.worth)}
       sort="textual content"
     />
     <label htmlFor="firm">Firm *</label>
     <enter id="firm" identify="firm" required sort="textual content" />
     <label htmlFor="electronic mail">E-mail Handle *</label>
     <enter id="electronic mail" sort="electronic mail" identify="electronic mail" required />
     <label htmlFor="message">Message *</label>
     <textarea id="message" identify="message" required/>
     <button sort="submit">Submit</button>
   </kind>
 );
 
 return (
   <div>
     <h1>Contact Us</h1>
{formVisible ? ContactForm : ConfirmationMessage}
   </div>
 );
};
 
export default ContactPage;
