You will need to have a functioning WordPress site. Ideally, you should know how to create a test or development site, since many of our examples will change the frontend of your site and you don't want your visitors seeing a work-in-progress store.

I highly recommend that you always keep WordPress and WooCommerce in their latest versions, as well as all plugins and themes for that matter. The further you are behind the latest live version, the more things won't work. It's also helpful, but not necessary, to have familiarity with HTML, CSS, JavaScript, and PHP.

If you are using the digital version of this book, we advise you to type the code yourself or access the code via the GitHub repository (link available in the next section). Doing so will help you avoid any potential errors related to the copying/pasting of code.

You can download the example code files for this book from your account at www.packt.com. If you purchased this book elsewhere, you can visit www.packtpub.com/support and register to have the files emailed directly to you.

You can download the code files by following these steps:

1. Log in or register at www.packt.com.
2. Select the Support tab.
3. Click on Code Downloads.
4. Enter the name of the book in the Search box and follow the onscreen instructions.

Once the file is downloaded, please make sure that you unzip or extract the folder using the latest version of:

• WinRAR/7-Zip for Windows
• Zipeg/iZip/UnRarX for Mac
• 7-Zip/PeaZip for Linux

The code bundle for the book is also hosted on GitHub at https://github.com/PacktPublishing/Mastering-WooCommerce-4. In case there's an update to the code, it will be updated on the existing GitHub repository.

We also have other code bundles from our rich catalog of books and videos available at https://github.com/PacktPublishing/. Check them out!

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "You can pass in a $args array."

A block of code is set as follows:

// Check to make sure WooCommerce is active
 if ( in_array( 'woocommerce/woocommerce.php', apply_filters('active_plugins', get_option('active_plugins')))) {
     ((our existing code))
 }

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "And then click the Features tab."
