Wordpress - Theme Structure and Basics

How can you disable the WordPress admin bar for all users except administrators by adding code to functions.php?

A<pre>add_filter('show_admin_bar', '__return_false');</pre>

<pre>add_action('after_setup_theme', function() {
  if (!current_user_can('administrator')) {
    show_admin_bar(false);
  }
});</pre>

C<pre>remove_action('wp_head', 'wp_admin_bar_render');</pre>

<pre>if (is_user_logged_in()) {
  show_admin_bar(false);
}</pre>

Step-by-Step Solution

Solution:

Step 1: Identify the correct hook and condition
Using after_setup_theme ensures the code runs early. Checking current_user_can('administrator') targets admin users.
Step 2: Use show_admin_bar(false) to disable the admin bar for non-admins
This disables the admin bar only for users without administrator capability.
Step 3: Review incorrect options
```
add_filter('show_admin_bar', '__return_false');
```
disables admin bar for all users, C removes rendering but is incomplete, D disables for all logged-in users.
Final Answer:
add_action('after_setup_theme', function() { if (!current_user_can('administrator')) { show_admin_bar(false); } }); -> Option B
