Issues with Netlify Form Submissions in Your Next.js 14 Project? Here’s the Fix!

Are you tired of dealing with frustrating form submission issues on your Netlify-hosted Next.js 14 project? You’re not alone! As a developer, there’s nothing more annoying than spending hours building a beautiful form, only to have it fail when users try to submit it. In this article, we’ll dive into the common issues that can arise with Netlify form submissions in Next.js 14 and provide you with actionable solutions to get your forms working seamlessly.

What’s the Problem?

Before we dive into the solutions, let’s quickly cover the common issues you might be experiencing with Netlify form submissions in your Next.js 14 project:

• Forms not submitting at all
• Unexpected 404 errors
• Form data not being sent to the server
• Issues with server-side rendering (SSR)

Check Your Netlify Configuration

The first step in troubleshooting Netlify form submission issues is to ensure that your Netlify configuration is set up correctly. Here are a few things to check:

1. netlify.toml file: Make sure you have a netlify.toml file in the root of your project, and that it’s correctly configured for your Next.js 14 project.
2. Forms settings: Verify that your forms settings are enabled in the Netlify dashboard. You can do this by going to Settings > Forms and ensuring that the “Forms” toggle is enabled.
3. Redirects: Check that you don’t have any redirects set up that might be interfering with your form submissions. You can check your redirects in the Netlify dashboard by going to Settings > Redirects.

Next.js 14 Form Submission Issues

Now that we’ve ruled out any Netlify configuration issues, let’s dive into some common problems that can arise with form submissions in Next.js 14:

Issue 1: Forms Not Submitting

If your forms aren’t submitting at all, it might be due to a simple mistake in your code. Here are a few things to check:

• Form tag: Ensure that you have a valid <form> tag with an action attribute pointing to the correct URL.
• Method: Verify that the method attribute is set to “POST” (or the method you’re using).
• CSRF token: If you’re using a CSRF token, make sure it’s properly generated and included in your form.

Here’s an example of a basic form in Next.js 14:

<form action="/contact" method="post">
  <label>Name:</label>
  <input type="text" name="name" />
  <label>Email:</label>
  <input type="email" name="email" />
  <button type="submit">Send</button>
</form>

Issue 2: Unexpected 404 Errors

If you’re seeing 404 errors when submitting your form, it might be due to a routing issue. Here’s what to check:

• Server-side rendering (SSR): Ensure that you have SSR enabled in your Next.js 14 project. You can do this by adding the following code to your next.config.js file:

module.exports = {
  // Enable server-side rendering
  target: 'serverless'
};

• Page route: Verify that you have a page route set up to handle the form submission. For example, if your form is posting to “/contact”, you’ll need a page route set up to handle the submission:

import { NextApiRequest, NextApiResponse } from 'next';

const ContactPage = () => {
  return (
    <div>
      <h1>Contact Page</h1>
      <form action="/contact" method="post">
        <label>Name:</label>
        <input type="text" name="name" />
        <label>Email:</label>
        <input type="email" name="email" />
        <button type="submit">Send</button>
      </form>
    </div>
  );
};

export default ContactPage;

Issue 3: Form Data Not Being Sent

If you’re not receiving any form data on the server-side, it might be due to a issue with how you’re handling the form submission. Here’s what to check:

• Form encoding: Ensure that you’re using the correct form encoding. You can do this by adding the enctype attribute to your form tag:

<form action="/contact" method="post" enctype="application/x-www-form-urlencoded">
  <label>Name:</label>
  <input type="text" name="name" />
  <label>Email:</label>
  <input type="email" name="email" />
  <button type="submit">Send</button>
</form>

• Server-side handling: Verify that you’re properly handling the form submission on the server-side. You can do this by creating an API route to handle the form submission:

import { NextApiRequest, NextApiResponse } from 'next';

const ContactApi = async (req: NextApiRequest, res: NextApiResponse) => {
  if (req.method === 'POST') {
    const { name, email } = req.body;
    // Handle form data here
    res.status(201).json({ message: 'Form submitted successfully!' });
  } else {
    res.status(405).json({ message: 'Method not allowed' });
  }
};

export default ContactApi;
