How to Configure and Customize the Google Map Field in Your Form

When creating dynamic web forms, adding a Google Map field allows users to input geographical data directly. This can be particularly useful for businesses that require location input, such as address information or geographic selections. The image above provides a clear representation of how a Google Map field configuration panel appears, complete with adjustable settings. Let’s walk through these settings and explain how each element contributes to the functionality of the form.

1. Required Checkbox

At the top of the configuration panel, we have the Required checkbox. When checked, this field becomes mandatory for the user to fill out. If left unchecked, users can skip this field without hindering form submission. For location-based forms, setting this field as required may ensure users provide essential geographical data.

2. Label Field

The Label field lets you specify the name of the field, which is displayed to the user. In this example, “Google Map” is used as the label, making it clear to the user that the field will involve a map. You can customize this to match your form’s context, such as “Select Location” or “Your Address.”

3. Help Text

The Help Text field provides a way to offer additional guidance to users. This field allows you to insert a small description or tip for users on how to interact with the map. Help text could include something like, “Drag the marker to your location” or “Enter your address to pinpoint the location on the map.” Adding help text ensures that users have a smoother experience, especially if the functionality of the map isn’t immediately obvious.

4. Placeholder

The Placeholder field is typically used for input fields where text is entered, but for a Google Map, this could represent default text or instructions shown before the user interacts with the field. You could use a placeholder like “Select your location” to nudge users toward interacting with the map.

5. Class

The Class field allows developers to add CSS classes for further customization. By inputting specific class names, you can style the map container or field according to your website’s design. For example, you could add a class to adjust the map’s size, border, or other visual elements to better fit into your form’s layout.

6. Name

The Name field is essential for back-end processing. The name is usually auto-generated to ensure uniqueness (e.g., google_map-1728837729754 in this case). This unique identifier will be used when submitting form data to the server, allowing the form handler to retrieve and process the map data correctly.

7. Country Code

The Country Code field is used to narrow down the geographical search scope of the Google Map. In this example, “pk” is entered, which stands for Pakistan. This can be adjusted based on the form’s requirements. For example, setting a country code ensures that the map focuses on a specific region, reducing ambiguity for users when they input their location.

Benefits of a Google Map Field

Adding a Google Map field to your form provides several benefits:

  • Enhanced User Experience: Users can easily select locations by dragging a pin on the map instead of manually entering addresses.
  • Accuracy: Maps reduce the likelihood of users making errors when entering location data, as they can visually confirm the correct address or location.
  • Flexibility: The country code setting allows for regional focus, and the map can be styled with custom classes for consistency across different form designs.

This is how it looks in the form

To use Google Maps in your application, you need to obtain an API key and enable the Places API. Below are step-by-step instructions on how to achieve both.

1: Create a Google Cloud Project

  • Go to the Google Cloud Console.
  • If you don’t have a Google account, sign up for one and log in.
  • In the Google Cloud Console, click the Select a Project dropdown at the top of the page.
  • Click New Project.
  • Name your project and click Create. You’ll now have a Google Cloud Project.

2: Enable Billing for Your Project

Google Maps services require billing to be enabled. You won’t be charged if you stay within the free tier, but billing must be activated.

  • In the Google Cloud Console, go to Billing from the navigation menu.
  • Select Manage Billing Accounts.
  • Link your project to a billing account, or create a new billing account if you don’t have one.
  • Enter the necessary information, such as credit card details, to enable billing.
  • Google offers $300 in free credits for new users, which you can use to test the APIs.

3: Get a Google Maps API Key

  • In the Google Cloud Console, go to the APIs & Services dashboard.
  • Click on Credentials from the left-side navigation.
  • Click Create Credentials and select API Key.
  • A new API key will be generated.
  • Copy the API key that appears, as you will need it later in your application.
  • Optionally, you can restrict your API key to specific websites or IP addresses by clicking on the Edit (pencil icon) next to your API key and selecting Application restrictions. Choose “HTTP referrers (web sites)” if you’re using this for a website, and add the domain (or domains) you want to restrict the API key to.

4: Enable Required APIs

For basic Google Maps functionality, you need to enable the following APIs:

  • Maps JavaScript API: Allows embedding and customization of maps on your website.
  • Places API: Allows your application to access location-based data, like searching for places, autocomplete for addresses, etc.

Enable Maps JavaScript API:

  • Go to the APIs & Services dashboard.
  • Click Library in the left-hand menu.
  • In the search bar, type Maps JavaScript API and select it from the list.
  • Click the Enable button.

Enable Places API:

  • From the APIs & Services dashboard, click Library again.
  • In the search bar, type Places API and select it from the list.
  • Click the Enable button.

5: Add the API Key to Your Settings

Once you have the API key and the necessary APIs are enabled, you can now use the key in your settings.

6: Test the API Key

  • Ensure that your API key is working by testing the implementation on your website or application.
  • If you restricted your API key to specific domains or IP addresses, make sure your website’s domain is correctly configured.
  • If everything is set up correctly, your Google Map or Places autocomplete should now be functional.

Final Notes:

  • API Quotas: Google offers $200 worth of free usage per month, which usually covers the needs of small applications or development purposes. You can monitor your usage in the Google Cloud Console to avoid unexpected charges.
  • Security: Restrict your API key to specific referrers (like domains or IP addresses) to prevent unauthorized use of your API key.

By following these steps, you’ll be able to get a Google Maps API key and enable the Places API for your application!
