How to create a file upload form in Gatsby.js

To create a file upload form in Gatsby.js using FabForm, you’ll first set up your Gatsby project, integrate FabForm for form handling, and then create the file upload form.

Here’s a step-by-step guide:

Step 1: Set Up Your Gatsby Project

If you haven’t already, install Gatsby CLI:

npm install -g gatsby-cli

Create a new Gatsby project:

gatsby new my-gatsby-project
cd my-gatsby-project

Step 2: Integrate FabForm

Add the FabForm script to your Gatsby project. You can include it in the <head> section of your layout component or individual pages where you want to use the form.

// Example layout component
import React from "react";
import { Helmet } from "react-helmet";

const Layout = ({ children }) => (
  <>
    <Helmet>
      <script src="https://cdn.jsdelivr.net/npm/fabform@latest/dist/fabform.min.js" defer />
    </Helmet>
    {children}
  </>
);

export default Layout;

Step 3: Create the File Upload Form

Create a new component for your file upload form. Here’s an example:

// src/components/FileUploadForm.js
import React from "react";

const FileUploadForm = () => {
  const handleSubmit = (event) => {
    event.preventDefault();
    const form = event.target;
    window.fabform.submitForm(form);
  };

  return (
    <form id="file-upload-form" action="https://fabform.io/f/YOUR_FORM_ID" method="POST" encType="multipart/form-data" onSubmit={handleSubmit}>
      <div>
        <label htmlFor="name">Name:</label>
        <input type="text" id="name" name="name" required />
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <input type="email" id="email" name="email" required />
      </div>
      <div>
        <label htmlFor="file">Upload File:</label>
        <input type="file" id="file" name="file" required />
      </div>
      <button type="submit">Submit</button>
    </form>
  );
};

export default FileUploadForm;

Replace YOUR_FORM_ID with your actual FabForm form ID.

Step 4: Use the File Upload Form

You can use the FileUploadForm component in any of your Gatsby pages:

// src/pages/contact.js
import React from "react";
import Layout from "../components/layout";
import FileUploadForm from "../components/FileUploadForm";

const ContactPage = () => (
  <Layout>
    <h1>Contact Us</h1>
    <FileUploadForm />
  </Layout>
);

export default ContactPage;

Step 5: Styling (Optional)

Style your file upload form using CSS to match your site’s design.

Step 6: Test Your Form

Start your Gatsby development server and test the file upload form:

gatsby develop

Open your browser and navigate to http://localhost:8000/contact (assuming you have a page named contact.js). You should see the file upload form, and you can submit files along with other form data.
