How to Add a Cost Calculator to Your WooCommerce Single Product Page?

Adding additional functionality to your WooCommerce single product pages can greatly enhance user experience and provide valuable features for potential customers. One such feature is a cost calculator form, which allows users to inquire about specific products directly from the product page. In this tutorial, we’ll walk through the process of adding this form to your WooCommerce single product page in WordPress.

Prerequisites

Before we begin, ensure that you have the following:

  1. A WordPress website with WooCommerce installed and activated.
  2. Access to your WordPress dashboard with administrative privileges.
  3. Cost calculator or any other form/content you would like to add to your single product page.

Cost Calculator Builder plugin overview

Cost Calculator Builder is the ideal tool for effortlessly creating price estimation forms to provide clients with service and product cost information. This WordPress plugin features a drag-and-drop calculation form builder, allowing for the creation of unlimited calculation forms. It offers various elements such as Input Text Box, Quantity Box, Dropdown Box, and more. Upgrade to the PRO version for additional features like WooCommerce integration, PayPal payments, Stripe support, and more.

Step 1: Locate Your Theme’s Functions.php File

First, you’ll need to locate the functions.php file of your WordPress theme. This file is typically found within your theme’s directory.

Alternative Step 1: Use a Plugin Called Code Snippets

While adding functionality directly to your theme’s functions.php file is a common approach, a more flexible and manageable option is to use a plugin like “Code Snippets.” This plugin allows you to add custom PHP code snippets to your WordPress website without directly editing theme files.

Why Use Code Snippets?

  1. Modularity: Code Snippets allows you to organize your custom code snippets into individual snippets, making it easier to manage and maintain.
  2. No Theme Dependency: Adding code snippets via a plugin ensures that your customizations remain intact even if you switch themes.
  3. Error Handling: Code Snippets provides error checking and syntax highlighting, helping to prevent potential issues with your custom code.
  4. Safety: It offers a safe environment to experiment with custom code without the risk of breaking your website.

Step 2: Add the Enquiry Form Code

Open the functions.php file in a text editor, and add the following PHP code snippet (see below). Or, add this snippet using a Code Snippets plugin:

  1. Add New Snippet: Once activated, go to “Snippets” > “Add New” in your WordPress dashboard.
  2. Paste the Code: Copy the PHP code snippet provided earlier for adding the cost calculator form, and paste it into the code editor.
// Adds a Cost Calculator on your WooCommerce Single product page
add_action( 'woocommerce_product_meta_end', 'enquiry_form', 30 );
function enquiry_form() {
    echo '<button type="submit" id="trigger_cf" class="button alt">Calculate the renovation cost »</button>';
    echo '<div id="product_inq" style="display:none">';
    echo do_shortcode('[stm-calc id="4393"]'); // Replace with your own shortcode
    echo '</div>';
}

add_action( 'woocommerce_product_meta_end', 'enquiry_form_1', 40);
function enquiry_form_1() {
    ?>
    <script type="text/javascript">
        jQuery('#trigger_cf').on('click', function(){
            if ( jQuery(this).text() == 'Calculate the renovation cost »' ) {
                jQuery('#product_inq').css("display","block");
                jQuery("#trigger_cf").html('Close');
            } else {
                jQuery('#product_inq').hide();
                jQuery("#trigger_cf").html('Calculate the renovation cost »');
            }
        });
    </script>
    <?php    
}

This code will add a cost calculator button and a hidden form section to your WooCommerce single product pages.

Step 3: Test the Cost Calculator

Visit a single product page on your WooCommerce website, and you should now see a button labeled “Calculate the renovation cost »”. Clicking on this button will reveal the cost calculator form where users can inquire about the product.

Enhanced Option: Displaying the Calculator Directly

In addition to adding a cost calculator form button, another approach is to display the calculator directly on the WooCommerce single product page without the need for users to click on a separate button. This can provide a more seamless user experience and make the calculator more readily accessible.

You can use the provided code snippet below to directly display the calculator on the single product page:

// Adds a Cost Calculator on your WooCommerce Single product page
add_action( 'woocommerce_product_meta_end', 'your_function', 30 );
function your_function() {
   echo ('<h2>Your text</h2>');
   echo do_shortcode('[stm-calc id="4393"]');
}

This code snippet hooks into the WooCommerce single product page and executes a function (your_function) after the “add to cart” button section. Inside the function, it first echoes any text you want to display (in this case, <h2>Your text</h2>, followed by the shortcode which renders the calculator.

Conclusion

Congratulations! You’ve successfully added a cost calculator to your WooCommerce single product pages in WordPress. This feature can help enhance user engagement and provide a convenient way for potential customers to get in touch with you regarding specific products. Experiment with the code and customize it further to suit your website’s design and functionality needs.
