Frequency: Customize the Default Autoship Frequency Options

Customize Autoship Frequency Options to include selections for the following frequency types:

• Days
• Weeks
• Months
• DayOfTheWeek
• DayOfTheMonth

Important: Always test customizations to your site on a staging environment before making changes to your live / production site.  If you are not experienced with testing changes on a staging site, here is a good article to review.

/**

* @param array $default_options The current drop down options.
* @param int $product_id The Simple or variation product id.
* @return array the filtered frequency options.
