Using Snippet Managers

Using Snippet Managers

While you can add this code directly to your theme's functions.php file, using a snippet manager plugin is often a better practice. This approach prevents "theme-lock," ensuring the shortcode continues to work even if you switch or update your WordPress theme.

Popular snippet managers include Code Snippets, WPCode, or Advanced Ads.

Benefits of Using a Snippet Manager

• Theme Independence: Your user role shortcode remains active regardless of theme changes.
• Safety: Most snippet managers include error catching; if there is a syntax error, the plugin will deactivate the snippet instead of breaking your site.
• Organization: Keeps your custom code separate from core theme files, making it easier to manage and debug.

Step-by-Step Integration (e.g., Code Snippets)

Follow these steps to implement the code using a snippet manager:

1. Install a Snippet Manager: Go to Plugins > Add New in your WordPress dashboard and search for "Code Snippets." Install and activate it.
2. Create a New Snippet: Navigate to Snippets > Add New.
3. Add the Code:
   • Give your snippet a title (e.g., "Display User Role Shortcode").
   • Copy the code from app.php in this repository.
   • Paste the code into the Code text area.

   // Example code from app.php
   function wp_show_user_role_shortcode() {
       if ( is_user_logged_in() ) {
           $user = wp_get_current_user();
           $roles = ( array ) $user->roles;
           return esc_html( reset( $roles ) );
       }
       return '';
   }
   add_shortcode( 'user_role', 'wp_show_user_role_shortcode' );
   

4. Set Execution Rules: Ensure the "Run snippet everywhere" or "Only run on site front-end" option is selected.
5. Save and Activate: Click Save Changes and Activate.

Displaying the Role

Once the snippet is active, you can use the shortcode anywhere on your site:

• In Pages/Posts: Add a Shortcode block and enter [user_role].
• In Widget Areas: Add a Text or Shortcode widget and enter [user_role].
• In PHP Templates: If you need to call it directly in a template file, use:

  <?php echo do_shortcode( '[user_role]' ); ?>
