Conditional cart pages based on product categories in woocommerce

To create conditional cart pages based on product categories in WooCommerce, you can implement a solution that customizes the cart page based on the category of the products in the user’s cart. Here’s an approach to achieve this:

1. Use a Custom Cart Page Template

WooCommerce allows you to customize your cart page by overriding templates. You can create a custom cart page template based on the categories of products in the cart.

Here are the steps:

Step 1: Create a Child Theme (if you don’t have one already)

To prevent your changes from being overwritten when the theme is updated, it’s recommended to use a child theme. If you already have a child theme, you can skip this step.

1. Create a new folder in the wp-content/themes directory (e.g., your-theme-child).
2. Create a style.css file in that folder and add the following:

/*
Theme Name: Your Theme Child
Template: your-theme
*/

3. Create a functions.php file in the same folder and add:

<?php
// Enqueue parent theme styles
function your_theme_child_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
add_action( 'wp_enqueue_scripts', 'your_theme_child_enqueue_styles' );

Step 2: Customize the Cart Page Based on Product Categories

In your child theme, copy the WooCommerce cart template from the parent theme to your child theme:

1. Copy the cart folder from the WooCommerce plugin directory (wp-content/plugins/woocommerce/templates/cart/) to your child theme’s directory under your-theme-child/woocommerce/cart/.

   The copied file should be your-theme-child/woocommerce/cart/cart.php.

2. In the cart.php file, add your custom logic to check the product categories and adjust the layout or content accordingly.

For example:

<?php
// Get cart items
$items = WC()->cart->get_cart();
$has_category = false;

// Check if the cart contains products from a specific category
foreach ($items as $item) {
    $product = $item['data'];
    $categories = wp_get_post_terms($product->get_id(), 'product_cat');
    foreach ($categories as $category) {
        if ($category->slug == 'your-category-slug') {
            $has_category = true;
            break;
        }
    }
}

// Conditional content based on category presence
if ($has_category) {
    // Display content or redirect for products in a specific category
    echo "<p>Special offer for this category!</p>";
} else {
    // Default cart page content
    echo "<p>No special offers available for your current cart.</p>";
}
?>

This example checks whether any product in the cart belongs to a specific category (your-category-slug). If it does, you can show special content or change the cart’s behavior.

Step 3: Customize Cart Behavior (Optional)

If you want to change the cart behavior (like redirecting users to a different page or displaying custom notices), you can hook into WooCommerce actions.

For example, redirect users to a custom cart page if their cart contains specific categories:

function redirect_based_on_category() {
    $items = WC()->cart->get_cart();
    $has_category = false;

    foreach ($items as $item) {
        $product = $item['data'];
        $categories = wp_get_post_terms($product->get_id(), 'product_cat');
        foreach ($categories as $category) {
            if ($category->slug == 'your-category-slug') {
                $has_category = true;
                break;
            }
        }
    }

    if ($has_category && !is_page('your-special-cart-page')) {
        wp_redirect(home_url('/your-special-cart-page'));
        exit;
    }
}
add_action('template_redirect', 'redirect_based_on_category');

This code snippet will redirect users to a custom cart page if the cart contains products from a specific category.

Step 4: Add Custom Styling (Optional)

You can also add custom CSS for your conditional cart page by adding the styles to the style.css of your child theme or through the Customizer.

/* For cart pages containing specific products */
.woocommerce-page .your-category-class {
    background-color: #f1f1f1;
}

Conclusion

By overriding the cart.php template and using WooCommerce hooks, you can create a conditional cart page that adapts based on the product categories in the cart. You can use this technique to display special offers, redirect users, or change the cart layout based on specific conditions.
