This article explains how to properly install Product Personalizer into a shop using the Shopify’s default Debut theme. You will need to insert a few lines of code: one into the product template, a number of modifications to the cart template, and an optional update to the our app’s stylesheet, as explained below.

From your Shopify Admin, click Online Store > Themes and then click on the “” menu for your theme. From here click Edit HTML / CSS. This will let you edit your theme and add the necessary code.

We have some code samples to guide you below. Please note the following:

  • Lines highlighted in green / beginning with a “+” symbol show you what to add.
  • DO NOT include “+” or “-” signs if you copy / paste this code into your theme.

If you experience any difficulties with the installation of the app, please contact us and we’ll be happy to assist.

This step adds your Product Personalizer options to your product pages. Go to the Sections > product-template.liquid file in the theme and add the following line of code to the “add-to-cart” form:

{% include 'product-personalizer' %}

<form action=”/cart/add” method=”post” enctype=”multipart/form-data” class=”product-form product-form-{{ }}{% unless section.settings.show_variant_labels %} product-form–hide-variant-labels{% endunless %}” data-section=”{{ }}”>
<select name=”id” id=”ProductSelect-{{ }}” data-section=”{{ }}” class=”product-form__variants”>
{% for variant in product.variants %}
{% if variant.available %}
{% comment %}
Note: if you use option_selection.js, your <select> tag will be overwritten, meaning what you have inside <option> will not reflect what you coded below.
{% endcomment %}
<option {% if variant == product.selected_or_first_available_variant %} selected=”selected” {% endif %} data-sku=”{{ variant.sku }}” value=”{{ }}”>{{ variant.title }}</option>
{% else %}
<option disabled=”disabled”>
{{ variant.title }} – {{ ‘products.product.sold_out’ | t }}
{% endif %}
{% endfor %}
+ {% include ‘product-personalizer’ %}
{% if section.settings.show_quantity_selector %}
<div class=”product-form__item product-form__item–quantity”>
<label for=”Quantity-{{ }}”>{{ ‘products.product.quantity’ | t }}</label>
<input type=”number” id=”Quantity-{{ }}” name=”quantity” value=”1″ min=”1″ class=”product-form__input” pattern=”[0-9]*”>
{% endif %}
<div class=”product-form__item product-form__item–submit”>
<button type=”submit” name=”add” id=”AddToCart-{{ }}” class=”btn product-form__cart-submit{% if product.options.size == 1 and product.variants[0].title == ‘Default Title’ %} product-form__cart-submit–small{% endif %}”>
<span id=”AddToCartText-{{ }}”>{{ ‘products.product.add_to_cart’ | t }}</span>
<div class=”product-single__description rte” itemprop=”description”>
{{ product.description }}
{% if section.settings.show_share_buttons %}
{% include ‘social-sharing’, share_title: product.title, share_permalink: product.url, share_image: product %}
{% endif %}
