Building Custom Forms

Liquid custom forms handle Shopify input with validation.

Introduction to Liquid Custom Forms

Liquid custom forms in Shopify allow you to create dynamic and interactive input fields tailored to your store's needs. These forms can handle user input effectively and ensure data integrity through validation.

Creating a Basic Custom Form

To create a basic custom form in Shopify using Liquid, you need to understand the form tag, input types, and how to capture the data. Here's a simple example of a contact form:

Understanding Form Validation

Validation ensures that the data entered by users meets certain criteria before it is processed. In Liquid, you can use HTML5 attributes like required, minlength, and pattern for basic validation. However, for more complex validation, you may need JavaScript.

Advanced Validation with JavaScript

For advanced validation scenarios, JavaScript can be utilized to provide real-time feedback or to handle more complex logic. Here's an example of using JavaScript to validate an email input:

Handling Form Submission

Once the form data is validated, it's crucial to handle the submission efficiently. Shopify forms are typically submitted via POST requests. You can use Shopify's built-in mechanisms to process these forms, or handle them through custom scripts if additional processing is required.
