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

Subsequent.js is a strong React framework for creating performant React functions that scale. By integrating a Subsequent.js website with Netlify’s know-how, we will rapidly get a working contact type up and operating with out having to write down any server-side code.

Not solely is it a comparatively quick course of to arrange varieties to be processed by Netlify, but it surely’s additionally free to get began (with as much as 100 free submissions/per website hosted on Netlify). Type submissions routinely 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 type

Inside the Subsequent.js software we should always create a ContactForm part to render the contact type within the contact web page. For those who’d like for this kind to render at /contact, then the ContactForm part under with labels and enter fields needs to be used throughout the pages/contact.js file.

const ContactForm = (
  <type
    identify="contact-form"
    methodology="POST"
    motion="contact/?success=true"
  >
    <label htmlFor="identify">Identify *</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="e mail">E-mail Handle *</label>
    <enter id="e mail" sort="e mail" identify="e mail" required />
    <label htmlFor="message">Message *</label>
    <textarea id="message" identify="message" required></textarea>
    <button sort="submit">Submit</button>
  </type>
);

The above markup is required to render a type with a discipline for Identify, Firm, E-mail tackle 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’s not but a distinction between the web page’s look with and with out the success question parameter, however we’ll 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 now we have the essential type arrange, the true magic will occur after we add further info for Netlify to auto-recognize the shape throughout future website deployments. To perform this we should always replace the shape to have the attribute data-netlify="true" and a hidden enter discipline that comprises the identify of our contact type. In Netlify, as soon as we navigate to our website within the dashboard after which click on on the “varieties” tab  we will view our type responses primarily based on the identify that we’ve put in our hidden discipline. It’s essential that in case you have a number of varieties inside a website that they’ve distinctive names in order that they’re recorded correctly in Netlify.

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

After efficiently deploying the positioning to Netlify with the data-netlify attribute and the form-name discipline  then we will go to the deployed model of the positioning and fill out the shape. Upon submitting the shape and navigating to https://app.netlify.com/websites/site-name/varieties (the place site-name is the identify of your website) then our most up-to-date type submission ought to seem if now we have efficiently arrange the shape. 

Redirect to affirmation display 

As a way to enhance the consumer expertise, we should always add some logic to redirect to a affirmation display on type submission when the URL modifications to /contact/?success=true. There’s additionally the choice to redirect to a completely totally different web page because the motion when the shape is submitted however utilizing question params we will obtain one thing comparable with the Subsequent Router. We are able to accomplish this by creating a brand new variable to find out if the affirmation display 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 and type can by no means be seen on the similar time; subsequently, the next assertion can be utilized to find out if the shape is seen or not.

const formVisible = !confirmationScreenVisible; 

To offer customers the choice to resubmit the shape, we will add a button to the affirmation display to reset the shape by clearing the question params. Utilizing router.exchange (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.exchange("/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 will 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.exchange("/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 discipline

Now that the core performance of our type is working, we will add further spam detection to our type 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 type.

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

We additionally have to create a brand new hidden paragraph that comprises a label named bot-field that comprises the enter. This discipline is “seen” to bots, however not people. When this honeypot type discipline is stuffed, 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 choice that Netlify helps by including reCAPTCHA 2 to a Netlify type.
  • We might replace the shape to permit uploaded recordsdata with enter <enter sort="file">.
  • We might arrange notifications for type submissions. That occurs over at https://app.netlify.com/websites/[your-site-name]/settings/varieties the place we will embrace a customized topic discipline (which might be hidden) for e mail notifications.

Full code

The code for the complete website code is on the market over at GitHub.

 Bonus

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

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.exchange("/contact", undefined, { shallow: true })}> Submit One other Response </button>
   </React.Fragment>
 );
 
 const ContactForm = (
   <type
     className="container"
     methodology="POST"
     identify="contact-form"
     motion="contact/?success=true"
     data-netlify="true"
     data-netlify-honeypot="bot-field"
   >
     <enter
       sort="hidden"
       identify="topic"
       worth={`You have bought 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">Identify *</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="e mail">E-mail Handle *</label>
     <enter id="e mail" sort="e mail" identify="e mail" required />
     <label htmlFor="message">Message *</label>
     <textarea id="message" identify="message" required/>
     <button sort="submit">Submit</button>
   </type>
 );
 
 return (
   <div>
     <h1>Contact Us</h1>
{formVisible ? ContactForm : ConfirmationMessage}
   </div>
 );
};
 
export default ContactPage;
