Modify wp-login.php labels: Username to Email

Question

How can you edit the labels of the wp-login.php form?

I am using emails for logins, so I need to change username to email.

The answer here seems to be out of date, or just doesn't work with SSL or something: Function to change a label (Username) in a core WordPress File (wp-includes/general-template.php)

I tried this in my functions file, but it didn't work:

function wpse60605_change_username_label( $defaults ) {
    $defaults['label_username'] = __( 'Email' );
    return $defaults;
}
add_filter( 'login_form_defaults', 'wpse60605_change_username_label' );

Answer 1

Found this here: https://wordpress.org/support/topic/how-to-change-the-text-labels-in-userpass-box-on-login-page/

The other answer here didn't work for me, but this one did.

Just in case this helps anyone.

add_filter( 'gettext', 'register_text' );
add_filter( 'ngettext', 'register_text' );
function register_text( $translated ) {
    $translated = str_ireplace(
        'Username or Email Address',
        'Your Custom Text',
        $translated
    );
    return $translated;
}

Found an answer on stackoverflow shortly after posting this:

Uses the gettext filter instead of any wp functions

Answer 3

Try this

add_filter(  'gettext',  'register_text'  );
add_filter(  'ngettext',  'register_text'  );
function register_text( $translating ) {
     $translated = str_ireplace(  'Username or Email Address',  'Your Custom Text',  $translating );
     return $translated;
}

Answer 4

In addition to changing the login screen, I wanted to remove the Username field from the admin Add New User form. This code added to functions.php did the trick:

function hide_username_field(){
    // Hide the username field on the admin Add New User form
    echo "\n" . '<script type="text/javascript">jQuery(document).ready(function($) {
        $(\'input#user_login\').parent().parent().hide();
        $(\'input#email\').change(function() {
            $(\'input#user_login\').val($(\'input#email\').val());
        });
    }); 
    </script>' . "\n";
}
add_action('admin_head','hide_username_field');
