How to fix checkout button in Shopify steps by steps

Work on Shopify liquid 

We won’t keep you waiting. Here’s how to fix the checkout button in Shopify step by step.

First, access your Shopify theme code:

1. Log in to your Shopify account.

2. Navigate to Online Store > Themes.

3. Click on “Actions” next to your current theme.

4. Select “Edit Code.”

Next, locate the checkout button:

1. Open the `cart.liquid` file. This file typically contains the code for your cart button.

2. Use the search function to find your checkout button. Look for `id=”checkout”` or relevant class names associated with the button.

Now, modify the checkout button code with these actions: 

Add comment tags around the existing button code. Here’s an example of how to do this:

<!--
<button type="submit" id="checkout" class="cart__checkout-button button" name="checkout" {% if cart == empty %} disabled{% endif %} form="cart">
    {{ 'sections.cart.checkout' | t }}
</button>
-->

Below the commented-out button code, add the new implementation:

{%- if cart != empty -%}
  <form action="{{ routes.cart_url }}/checkout" method="post" id="cart-form">
    <button 
      type="submit" 
      name="checkout" 
      class="cart__checkout-button button"
      {% if cart.items.size == 0 %}disabled{% endif %}
      data-cart-submit
    >
      {{ 'sections.cart.checkout' | t }}
      <span class="loading-spinner hidden">
        {% render 'icon-spinner' %}
      </span>
    </button>
    
    {% if cart.attributes != empty %}
      {% for attribute in cart.attributes %}
        <input type="hidden" name="attributes[{{ attribute.first }}]" value="{{ attribute.last }}">
      {% endfor %}
    {% endif %}
  </form>
{%- endif -%}

Remember to replace `your-store-name` with your actual Shopify store name.

To maintain consistent styling, copy the class attributes from the original button to the new link:

  <a href="https://your-store-name.myshopify.com/checkout" class="cart__checkout-button button">
      {{ 'sections.cart.checkout' | t }}
  </a>

Work on theme’s code 

If the above solutions don’t work, you may need to dig deeper into your theme’s code. Add this same code snippet to your theme’s JavaScript file or within a <script> tag in your product template.

document.addEventListener('DOMContentLoaded', function() {
  const cartForm = document.getElementById('cart-form');
  const checkoutButton = document.querySelector('[data-cart-submit]');
  const loadingSpinner = checkoutButton?.querySelector('.loading-spinner');

  if (cartForm && checkoutButton) {
    cartForm.addEventListener('submit', async function(event) {
      event.preventDefault();
      
      try {
        checkoutButton.disabled = true;
        loadingSpinner?.classList.remove('hidden');

        const cartResponse = await fetch('/cart.js');
        const cartData = await cartResponse.json();
        
        if (!cartData.items || cartData.items.length === 0) {
          throw new Error('Cart is empty');
        }

        window.location.href = '/checkout';
      } catch (error) {
        console.error('Checkout error:', error);
        const errorMessage = document.createElement('div');
        errorMessage.classList.add('cart-error');
        errorMessage.textContent = 'Unable to proceed to checkout. Please try again.';
        cartForm.insertBefore(errorMessage, checkoutButton);
      } finally {
        checkoutButton.disabled = false;
        loadingSpinner?.classList.add('hidden');
      }
    });
  }
});
