Disable WP Dashboard for Subscriber but Enable for Editor, Author and Other Custom Roles

Using the code below you can disable access to your WordPress Dashboard/Backend for selected roles and users belonging to that particular role. For example, if you want to restrict dashboard access to your guest users and users belonging to 'Subscriber' role then you may add the following code in your theme's function.php file or best way is to use the Code Snippet plugin.
 There are many added benefits, which you can read in the plugin's description page, when you use Code Snippet instead of directly inserting your code into your theme's function.php file.

 // Source: https://premium.wpmudev.org/blog/limit-access-to-your-wordpress-dashboard/  
 add_action( 'init', 'blockusers_init' );  
 function blockusers_init() {  
  if ( is_admin() && !current_user_can( 'administrator' )   
       && !current_user_can('editor')  
       && !current_user_can('author')  
       && !current_user_can('translator')  
       && !( defined( 'DOING_AJAX' ) && DOING_AJAX ) ) {  
      wp_redirect( home_url() );  
      exit;  
  }  
 }  

Note that I have also added a custom role called 'translator' in the above code.

Below is a screenshot of how I have added the code to my site by making use of the Code Snippet plugin.

Add Country Selection List to your BuddyPress Profile & Registration Page


Add Country List in BuddyPress Profile & Registration Page

In this tutorial I will show you how you can easily add a Country list, as shown in the image above to your BuddyPress User Extended Profiles or Wordpress Registration Page using BuddyPress.

1. First head over to Github & download the following code: http://bit.ly/2f0xk7X.

As you must have noticed in the comments, in the Github page of the above code; you may have to add the following line of code just before the foreach loop at line number 222; which is basically, you are initializing the value of $i to 1. 

 $i = 1;  //

Copy the above code and add it to your 'bp-custom.php' file. If this file already exists in your site then it should be located at 'wp-contents/plugins/bp-custom.php'; else you have to create it and place it at the aforementioned location. You can read more about 'bp-custom.php' file here: http://bit.ly/2y3IQak. There you will be able to understand why it's best to add the above code in your 'bp-custom.php' file and not in your theme's 'function.php' file.

Now, open the following link to access the Country List. Suppose, your site name is www.example.com, then you will have to enter: http://www.example.com/wp-admin/users.php?page=bp-profile-setup. You should now be able to view a Country List field as shown in the image below:

NOTE:
 - Once you are able to view the Country List in your Profile Fields page you may remove the above code from your 'bp-custom.php' file, else your 'bp_xprofile_fields' table, which is the table that stores the above country list might go on getting unnecessarily populated with the all the above 193 country names.
- Only edit your field after removing the above code from your bp-custom.php file for aforementioned reasons.
- If you would like to have the Delete option for this field in your Profile Fields Admin Page, then  change line 14 as below:
 'can_delete'   => true,  

- Likewise you can also alter the value of the 'name' and 'description' fields in the code itself.
