Troubleshooting Blank Submissions in Netlify Forms

If you've recently integrated a contact form using Netlify forms and noticed that submissions are coming through as blank messages, you’re not alone. This is a common issue that can arise when JavaScript validation isn’t correctly set up, particularly if you're using an anchor tag as your submit button. In this post, we'll dive deeper into how to fix this annoying problem and ensure your contact page submissions are filled out correctly every time.

Understanding the Problem

The Situation

Imagine you have a beautifully crafted contact form, but when users hit "Send Message," the form is submitted without any content. This not only frustrates users but also makes it difficult for you to engage with potential clients or customers. The reason for this issue can be traced back to JavaScript validation and how the form submission is triggered.

The Form Structure

To better understand the problem, let's take a look at a simplified version of your form's HTML structure:

What's Going Wrong

Missing Attributes: Your textarea needs the name and id attributes set correctly for the validation to work.

No Validation: The current JavaScript function does not validate whether the fields are filled out before submission.

Solution: Validating Form Submissions

Step 1: Update the Textarea Attributes

First, make sure your <textarea> element has both the name and id attributes. Here's how you can set it up correctly:

Step 2: Enhance the JavaScript Function

Next, modify your JavaScript function to include validation checks before form submission. Here is an updated version of your myFunction():

Breakdown of the Code

Validation Check: The if statement checks the length of the value in the textarea. If it’s zero, it triggers an alert asking the user to fill out the message field.

Conditional Submission: If the message has content, the form proceeds to submit as intended.

Conclusion

By ensuring that your form fields are properly configured and implementing basic JavaScript validation, you can prevent blank submissions on your contact page. These steps will not only improve user experience but will also enhance your ability to communicate effectively with your audience.

Now your contact form is all set to capture meaningful messages from your users instead of frustrating blank submissions. If you have any further questions or need additional help, feel free to reach out!
