Has anyone successfully implemented form validation in Webflow where an input must equal a specific value, displaying a success message if it matches and an error message if it doesn't?

Yes, it is indeed possible to implement form validation in Webflow where an input must equal a specific value and display a success message if it matches, or an error message if it doesn't.

To achieve this, you can use Webflow's built-in interactions and custom code. Here's a step-by-step guide:

1. Design your form in Webflow's Designer and add an input field for the value you want to validate.

2. Create two sections/divs within the form element, one for the success message and another for the error message. These sections should initially be hidden, so set their initial display to "none" in Webflow's Designer.

3. Select the input field and go to the "Interactions" panel. Add a new interaction.

4. In the interaction panel, choose the "Form Submission" trigger and set it to "Click" or "On form submit", depending on how you want the validation to be triggered.

5. Add a new action to the interaction. Select "Show" and choose the success message section/div. Customize the animation/fade-in effect if desired.

6. Still within the same action, add another action. This time, select "Hide" and choose the error message section/div. Again, you can customize the animation/fade-out effect.

7. Now, duplicate the previous action but reverse the settings. This time, show the error message section/div and hide the success message section/div.

8. After setting up the initial actions, we need to add a condition to check the input value. Click on the "+" icon within the action to add a new condition.

9. In the condition settings, choose the input field you want to validate. Select "Equals" and enter the specific value that the input should match.

10. Add the success and error actions you created in steps 5 and 7 to the respective condition outcomes. The success action should play if the input matches the specific value. The error action should play if the input doesn't match.

11. Finally, preview and test your form to see if the validation works as expected. Make sure to adjust the design and styling of the success and error messages to match your overall design.

By following these steps, you can successfully implement form validation in Webflow where an input must equal a specific value, displaying a success message if it matches, and an error message if it doesn't.
