1. Understand WooCommerce Product Attributes

Before creating a shortcode, ensure that:

Product Attributes are set up correctly in WooCommerce.
The attribute “Bandwidth” is added to your products.

Steps to Add a Product Attribute:

Navigate to WooCommerce Attributes:
- Go to your WordPress dashboard.
- Navigate to Products > Attributes.
Add a New Attribute:
- In the “Add new attribute” section, enter:
  - Name: Bandwidth
  - Slug: bandwidth
- Click Add attribute.
Configure Terms for the Attribute:
- After adding, click on Configure terms.
- Add terms like “100Mbps”, “200Mbps”, etc.
Assign Attribute to Products:
- Edit a product.
- In the Product data section, go to the Attributes tab.
- Select Bandwidth from the dropdown and click Add.
- Choose the appropriate bandwidth value.
- Save or update the product.

2. Create a Custom Shortcode

We’ll create a shortcode [product_bandwidth] that retrieves and displays the “Bandwidth” attribute for the current product.

Steps:

Access Your Theme’s functions.php File:
- It’s recommended to use a child theme to prevent losing changes during theme updates.
- Alternatively, you can use a site-specific plugin.

Add the Shortcode Code:

// Add this code to your child theme's functions.php or a site-specific plugin

// Function to retrieve and display the 'Bandwidth' attribute
function display_product_bandwidth() {
    global $product;

    if ( ! is_a( $product, 'WC_Product' ) ) {
        return '';
    }

    // Replace 'bandwidth' with your attribute's slug if different
    $bandwidth = $product->get_attribute( 'bandwidth' );

    if ( ! empty( $bandwidth ) ) {
        return '<div class="product-bandwidth"><strong>Bandwidth:</strong> ' . esc_html( $bandwidth ) . '</div>';
    }

    return '';
}

// Register the shortcode [product_bandwidth]
add_shortcode( 'product_bandwidth', 'display_product_bandwidth' );

Explanation:

display_product_bandwidth Function:
- Accesses the global $product object.
- Retrieves the “Bandwidth” attribute using $product->get_attribute( 'bandwidth' ).
- Returns a formatted HTML string displaying the bandwidth.
- If the attribute is not set, it returns an empty string.
add_shortcode:
- Registers the shortcode [product_bandwidth] linked to the display_product_bandwidth function.

3. Add the Shortcode to Your Theme

Ensure the shortcode is properly added to your site by placing the code in the correct location.

Using a Child Theme’s `functions.php`:

Access Your Site’s Files:
- Use FTP, cPanel, or the WordPress dashboard (Appearance > Theme Editor).
Edit functions.php:
- Open the functions.php file of your child theme.
- Paste the shortcode code provided above at the end of the file.
- Save the changes.

Using a Site-Specific Plugin:

Create a New Plugin:
- In your WordPress dashboard, go to Plugins > Add New.
- Click Add New and then Upload Plugin if you have a pre-made one, or use a plugin like Code Snippets for easier management.
Add the Shortcode Code:
- Paste the shortcode code into the plugin.
- Save and activate the plugin.

4. Use the Shortcode in Your Content

Now that the shortcode [product_bandwidth] is created, you can use it wherever shortcodes are accepted.

Where to Use:

Product Descriptions:
- Edit a product and insert [product_bandwidth] in the description or any other text area that supports shortcodes.
Product Pages via Hooks:
- If you want to display the bandwidth attribute automatically on all product pages without manually adding the shortcode, you can use WooCommerce hooks.
```
// Automatically display bandwidth on single product pages
function add_bandwidth_to_single_product() {
    echo do_shortcode( '[product_bandwidth]' );
}
add_action( 'woocommerce_single_product_summary', 'add_bandwidth_to_single_product', 25 );
```
- Explanation:
  - This code hooks the shortcode into the single product summary section.
  - The number 25 determines the priority; you can adjust it to position the output accordingly.

Example Usage in Content:

## Product Features

- High-speed internet
- Reliable connection
- [product_bandwidth]
- 24/7 Support

When viewed on the product page, [product_bandwidth] will be replaced with:

Bandwidth: 100Mbps

(Assuming the product has “100Mbps” set as its bandwidth.)

5. Testing and Troubleshooting

Testing:

Add the Shortcode:
- Insert [product_bandwidth] in a product’s description or other shortcode-enabled area.
View the Product Page:
- Ensure that the bandwidth information displays correctly.
Check for Multiple Products:
- Verify that different products display their respective bandwidth values.

Troubleshooting:

Shortcode Not Displaying:
- Ensure the shortcode is correctly added and there are no syntax errors in the functions.php or plugin file.
- Verify that the “Bandwidth” attribute is assigned to the product.
Empty Output:
- Confirm that the product has a value set for the “Bandwidth” attribute.
- Check that the attribute slug in the code matches exactly (case-sensitive).

Styling Issues:

The returned HTML includes a <div> with the class product-bandwidth. You can style this in your theme’s CSS:

.product-bandwidth {
    margin-top: 10px;
    font-size: 16px;
    color: #333;
}

.product-bandwidth strong {
    color: #000;
}

Conflicts with Other Plugins/Themes:
- Temporarily switch to a default theme (like Twenty Twenty-One) and disable other plugins to check for conflicts.

Additional Tips

Security: Always sanitize output using functions like esc_html() to prevent potential security issues.
Performance: Avoid adding heavy processing in the shortcode function to maintain site performance.

Extensibility: You can modify the shortcode to accept parameters, allowing more flexibility. For example:

function display_product_attribute( $atts ) {
    global $product;

    if ( ! is_a( $product, 'WC_Product' ) ) {
        return '';
    }

    $atts = shortcode_atts( array(
        'attribute' => '',
    ), $atts, 'product_attribute' );

    if ( empty( $atts['attribute'] ) ) {
        return '';
    }

    $attribute = $product->get_attribute( sanitize_text_field( $atts['attribute'] ) );

    if ( ! empty( $attribute ) ) {
        return '<div class="product-attribute"><strong>' . esc_html( ucfirst( $atts['attribute'] ) ) . ':</strong> ' . esc_html( $attribute ) . '</div>';
    }

    return '';
}
add_shortcode( 'product_attribute', 'display_product_attribute' );

Usage: [product_attribute attribute="bandwidth"]

This makes the shortcode reusable for any product attribute.

Conclusion

By following the steps above, you can create a custom shortcode in WooCommerce to display product attributes like “Bandwidth” wherever you need them on your site. This approach enhances flexibility and ensures consistency across your product displays.
