Restrict usernames to not include spaces

Hi @champsupertramp and @cjnash

I join the question, the same thing happens with the user field.

Field validation is enabled on unique username and it still allows spaces and that causes unexpected logout to occur

Hello again @champsupertramp

I need to be able to restrict spaces in usernames urgently, as the “unique username” field option seems to not work well. I need some solution, even if it is manual.

Please…

@srwayne and @cjnash

This code snippet should be your solution:

add_filter ( 'sanitize_user', 'my_um_remove_user_spaces', 10, 3);

function my_um_remove_user_spaces( $username, $raw_username, $strict = false ) {

    return str_replace( ' ', '', $username );
}

Install the code snippet in your child-theme functions.php file
or use the “Code Snippets” plugin.

I do not want to allow the user to give space in the username, tell any code for that

That is not working

I will make a second update of this code snippet.

Now the test for space is done only for the registration page
and if found spaces there is an error message.

Old registrations with spaces
which have been removed by the very first code snippet
the user can use spaces at login
and the username without spaces is used by UM and WP.

add_filter ( 'sanitize_user', 'my_um_remove_user_spaces', 10, 3);

function my_um_remove_user_spaces( $username, $raw_username, $strict = false ) {
    
    if( um_is_core_page( 'register' ) && strpos( trim( $username ), ' ' )) {
        UM()->form()->add_error( 'user_login', __( 'You are not allowed to have spaces in your username.', 'ultimate-member' ) );
    }
    return str_replace( ' ', '', $username );
}
