[Forum] Spaces in Username

[majsm]

How can I disable the space bar as a character in registration to prevent registration with a space?

[Deadly Stream]

Go to User Registration Options in the Admin Control panel (AdminCP > Settings > Options > User Registration Options).

Scroll down to Username Regular Expression and enter the following into the field;

^[A-Z0-9]+$

That will only allow names with A-Z & 0-9 without spaces. If you only wanted to allow letters and not numbers, use this code;

^[A-Z]+$

[majsm]

but the help menu says this "^[A-Z0-9 ]+$ - Alphanumeric characters including space"

doesn't this mean this will allow letters numbers and spaces?

[Deadly Stream]

That one will because of the space between 9 & ]. If you remove the space then users can't use them.
