Function Name: show_admin_bar
The show_admin_bar() function is a WordPress function that is used to display or hide the admin bar at the top of the page for logged-in users. The admin bar includes links to various WordPress functions such as adding new posts, editing your profile, and logging out.
By default, the admin bar is visible to all logged-in users. However, there may be instances where you want to hide it for certain users or on certain pages of your website. This is where the show_admin_bar() function comes in handy.
The show_admin_bar() function takes a single parameter, $show, which is a boolean value that determines whether the admin bar should be displayed or hidden. If $show is set to true, the admin bar will be displayed. If $show is set to false, the admin bar will be hidden.
Here is an example of how to use the show_admin_bar() function to hide the admin bar for non-admin users:
function hide_admin_bar() {
if (!current_user_can('administrator') && !is_admin()) {
show_admin_bar(false);
}
}
add_action('after_setup_theme', 'hide_admin_bar');
In this example, the function hide_admin_bar() is used to determine whether the current user is an administrator. If the current user is not an administrator and is not accessing the admin panel, the show_admin_bar() function is called with a parameter of false, which hides the admin bar.
Overall, the show_admin_bar() function is a simple and effective way to control the visibility of the WordPress admin bar on your website.
