I'm using the following code to hide the admin toolbar in the front end:
add_filter( 'show_admin_bar', '__return_false' );

But how do I hide this option in wp-admin?

Here's one way to hide it with CSS:

add_action( 'personal_options', function( $profileuser )
{
    ?><style>.show-admin-bar{ display: none;}</style><?php
} );

or rather place it within the <head>...</head> with:

add_action( 'admin_print_styles-user-edit.php', 'wpse_hide_admin_bar_settings' );
add_action( 'admin_print_styles-profile.php',   'wpse_hide_admin_bar_settings' );

function wpse_hide_admin_bar_settings()
{
    ?><style>.show-admin-bar{ display: none;}</style><?php
} 

You could perhaps add your own wpse_hide_admin_bar_settings filter if you need more control:

function wpse_hide_admin_bar_settings()
{
    if( (bool) apply_filters( 'wpse_hide_admin_bar_settings', false ) )
        echo '<style>.show-admin-bar{ display: none;}</style>';
} 

and then turn it off/on with:

add_filter( 'wpse_hide_admin_bar_settings', '__return_false' ); // show it
add_filter( 'wpse_hide_admin_bar_settings', '__return_true' );  // hide it

  • Thanks, that will work. Although one would think that when you disable this in the frontend, this option would at least be disabled backend. – Steven Feb 26 '16 at 9:19
  • If I understand your comment, Steven: a) The "Show Toolbar" option is something a user might want to enable some times and disable other times. If unchecking the option in the dashboard removed it from the dashboard, there's no way to re-enable it. b) Quite curious: why do you want to remove this feature? – Jeff Cohan Feb 26 '16 at 14:49
