How to Add a Custom Text Field on a Shopify Product Page for Free (Without Apps)

To add a custom text field to a Shopify product page without using apps, follow these steps using Shopify’s built-in Liquid customization:

1. Access the Theme Editor

  • From your Shopify admin, go to Online Store > Themes.
  • Click Customize on the theme you want to edit (e.g., “Dawn” in the screenshot).

2. Navigate to the Product Template

  • In the theme editor, select Products from the top menu.
  • Choose the default product template (e.g., “Default product”) to edit the product page layout.

3. Add a Custom Liquid Section

  • Scroll to the section where you want the text field (e.g., below the product image or description).
  • Click Add section or Add block, then search for and select Custom liquid.

4. Insert Liquid Code for the Text Field

In the Custom liquid field, add the following code to create a basic text input field:

<div class="custom-field">
  {{ product.custom_field }}
</div>
<textarea id="custom-print-message" placeholder="Custom Print Message" name="properties[Message]"></textarea>

This code creates a text area where customers can input custom text (e.g., a message to print).

5. Save Your Changes

  • Click Save in the theme editor to apply the changes.
  • The custom text field will now appear on the product page, as shown in the screenshot with the “Custom liquid” section.

6. Test the Field

  • Preview the product page to ensure the text field is visible and functional.
  • Customers can enter text, which will be included with their order details.

This method leverages Shopify’s Liquid templating system to add a custom text field without additional apps, keeping costs at zero. Note that this is a basic implementation; for more advanced features (e.g., validation or styling), you may need to adjust the CSS or consult Shopify’s documentation.

Why You Should Use an App Instead of Customizing the Code

While adding a custom text field through code is free and straightforward, using an app like Easify Custom Product Options offers significant advantages.

Apps provide a user-friendly interface to manage and customize fields without requiring coding knowledge, saving time and reducing the risk of errors that can break your store. They also offer advanced features such as real-time previews, validation options, and seamless integration with checkout processes, which are challenging to implement manually.

Additionally, apps receive regular updates and support, ensuring compatibility with Shopify’s evolving platform, whereas custom code may need frequent manual adjustments. For a hassle-free, scalable solution, an app is the smarter choice.

  • For Dimension: Implement dimension-based pricing with a creative workaround—add a checkbox labeled “custom dimension” with an extra fee. When selected, dimension fields appear; if unchecked, they remain hidden, ensuring a seamless user flow.

Step 6: Configure Additional Settings

Fine-tune the text field with advanced options: set character limits with text length, guide users with placeholder text (e.g., prompts like “Enter your message”), provide context with help text below the field, add informative tooltips that appear on hover, and adjust column width (e.g., 25%, 33%, 50%, 75%, or 100%) for optimal layout (e.g., three fields at 33% each).

Step 7: Assign Text Fields

Decide the scope by assigning the text fields to all products, manually selecting specific products, or using conditional rules based on product attributes for targeted customization.

Step 8: Control Visibility

Restrict or expand access by choosing which customers see the fields—options include all customers, logged-in users, guests, or specific groups identified by customer tags.

Step 9: Save Settings

Once all configurations are set, save your option set to apply the changes and make the custom text field live on your product pages. This approach ensures a professional, scalable solution with minimal effort compared to manual coding.

Final Thoughts

Adding a custom text field to your Shopify product page can significantly enhance customer engagement by offering personalized options, whether through a free coding approach or the advanced features of an app like Easify Custom Product Options.

The manual method is a great starting point for those comfortable with Liquid and seeking a cost-effective solution, but it comes with limitations in scalability and maintenance. On the other hand, leveraging an app provides a robust, user-friendly alternative with ongoing support and sophisticated customization, ideal for growing businesses.

Choosing the right method depends on your store’s needs—start simple with code or invest in an app for long-term success.
