I have got a basic registration and login forms and when the user registers then their information is sent to the database and when the user uses the same username and password then they can login into the site. Upon logging in, the user is directed to the account pages at where I am trying to get the logged in users information, like first name and surname.

I am trying to get my mysql database to update a value in a column when a checkbox is checked/unchecked. This works for 1 word variable, but somehow refuses when the checkbox that is checked has 2 words (in other words, has a space in the string).
