Accessing Single Errors from an Array in EJS: A Step-by-Step Guide

Have you found yourself struggling to access single errors from an array in your EJS forms? This common challenge can lead to displaying all error messages at the bottom of the form, which isn't the best user experience. Instead, we want to show error messages right next to their corresponding input fields. In this guide, we'll guide you through how to do just that.

The Problem

When a user submits a form with invalid data, your application generates error messages. If you are rendering these errors in EJS, especially in cases like forms with multiple fields, it can be tricky to display each error message directly under the respective invalid input. Instead, many developers find themselves listing errors at the bottom of the form, which can reduce usability.

In this example, we have a typical setup where you've attempted to display errors in a list format:

However, this doesn't pinpoint errors to their respective inputs.

The Solution

To improve user experience, it's essential to associate each error message directly with its input field. To do this, we can transform the errors array into an object that maps each input's name to its error message.

Step 1: Transform the Errors Array into an Object

Instead of passing an array of errors, we'll format them into an object. An example of the desired structure would look like this:

Step 2: Update Your Controller Logic

Here’s how to update your controller code to transform the existing errors array and pass it as an object:

Step 3: Update Your EJS Template

Now that we have a structured errors object, you can easily access specific error messages in your EJS template:

Additional Tips

Handle No Errors: Always consider the case where there might be no errors and ensure your code handles this gracefully.

Custom Styles: Enhance user experience by styling your error messages appropriately with CSS, so they're easily noticeable.

Conclusion

By transforming your errors array into an easily manageable object, you can provide a much cleaner and more user-friendly error handling experience in EJS forms. Now, users will see relevant error messages directly under the fields they're associated with, making it easier for them to correct their mistakes.

With this guide, you should have a clear path to fixing your issue of accessing individual errors in your EJS templates. Happy coding!
