Liquid Custom Form

Building a Custom Form

Liquid custom form handles Shopify input with validation logic.

Introduction to Liquid Custom Forms

Liquid custom forms are a powerful way to collect user input in Shopify. By using Liquid, you can create forms that not only capture data but also validate it before submission. This ensures that the data you collect is accurate and useful.

Creating a Simple Liquid Form

To create a basic custom form in Shopify using Liquid, you need to define your form structure using HTML and Liquid tags. Here's a simple example of a contact form:

Adding Validation Logic

Validation is crucial to ensuring that the data collected through your form is complete and formatted correctly. You can use both HTML5 attributes and Liquid logic for validation. Here's how you can enhance the previous form with basic HTML5 validation attributes:

Handling Form Submission with Liquid

Once your form is submitted, Shopify processes it based on the `action` attribute you defined in the form. You can use Liquid to handle the data on the server side, such as sending confirmation emails or storing information in a database. Unfortunately, Shopify does not allow backend scripting directly, so most server-side logic is handled through its built-in functionalities and third-party apps.

Using Liquid to Display Form Errors

When a form submission fails due to validation errors, it's important to provide feedback to the user. Liquid can be used to display error messages by checking the `form.errors` object. Here is an example of how you might show error messages:

Conclusion

Creating custom forms in Shopify using Liquid provides flexibility and control over how you collect and validate customer data. By leveraging Liquid's capabilities, you can ensure a seamless user experience while maintaining data integrity. For more complex logic, consider integrating with third-party apps that extend Shopify's native capabilities.
