 * Hello!
 * I am developing a WordPress plugin, and I am curious if I can use functions without
   Actions or Filters?
 * The reason I am asking is because I have added a button to a custom plugin page
   within the admin that uploads a CSV file.
 * When I click the button, it uses PHP_SELF to post the information back to the
   same page, and uses isset() to see if the data is available.
 * If it is available, I have a custom function that runs and uses:
 * wp_create_user()
 * However, it is giving me the error:
 * Fatal error: Call to undefined function wp_hash_password()
 * It is obvious this function does not exist in the wp-includes/registration.php
   file I loaded with require_once() in order to use wp_create_user()
 * It seems like wp_hash_password() is in a different file, and because I am not
   using a WordPress Action or Filter it is bypassing the loading stage for this
   file.
 * Is my thinking correct?

 * wp_hash_password is [defined](http://codex.wordpress.org/Function_Reference/wp_hash_password#Source_File)
   at wp-includes/pluggable.php. You haven’t used search.
