I have customized pro site level selection in my front page. While selecting one of this pro selection, user will redirect to word press create site page [I do not want to provide another pro site selection in sign up page. so I hide that in sign up page]. There I wan to create the site based on the pro site level value already selected in the front page. I am sending [POST] following values while the user click on sign up button. But still my new site is created as non-pro site.
extend_level = 2, level = 2 , period = 1
What are the pro site parameters I am suppose to send while create a site from WP sign-up page [remember, there is no pro site selection in sign-up page] ?
