Hello everyone,

In my WP multisite network, I'm trying to give new users the option of assigning an individual subdirectory string for the subsite they create with their registration. The registration form should already show the user what the future URL of their subsite will look like.

I have tried various ways and have always come to a dead end:

Putting it together as [siteurl]/[x] to display it in in a string- or a html-field, where x is the ID of the text field for entering the subdirectory string, works, but adding "sanitize=1" or "sanitize_url=1" does not work even when I'm using page breaks between the entry and the display field. This means that spaces and special characters are not converted to URL-specific strings and the user cannot see the final result.

The attempt to temporarily store the entire URL in a text calculation field [y] and then have it checked or corrected in a separate URL field failed, as I apparently cannot enter an ID [y] in the URL field. I hope I have been able to describe my problem clearly and would be grateful for any advice (even if someone has already faced the same problem and it simply cannot be solved).

Many thanks in advance!
