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."
