how to show logged user name in wordpress without plugin using shortcode

To display the currently logged-in user's name in WordPress without using a plugin, you can create a custom shortcode and add it to your theme's functions.php file. Here's a step-by-step guide:

Access Your Theme Files: Use an FTP client or the file manager provided by your hosting provider to access your WordPress theme files. Navigate to your theme folder, usually located in the "wp-content/themes/" directory. Edit functions.php: Inside your theme folder, find the functions.php file and open it for editing. If the file doesn't exist, you can create it. Add Custom Shortcode Function: Insert the following code into your functions.php file to create a custom shortcode that will display the logged-in user's name:

// Custom shortcode to display logged-in user's name function display_logged_in_username() { if (is_user_logged_in()) { $current_user = wp_get_current_user(); return 'Welcome, ' . esc_html($current_user->display_name) . '!'; } else { return 'Welcome, Guest!'; } } add_shortcode('logged_in_username', 'display_logged_in_username');

This code checks if a user is logged in and then retrieves the display name of the current user. If no user is logged in, it will display a default greeting for guests.

Use the Shortcode in Content or Widgets: You can now use the [logged_in_username] shortcode in your WordPress pages, posts, or widgets to display the logged-in user's name. Simply insert the shortcode wherever you want the name to appear. For example:

This is a sample page. [logged_in_username]

You can customize the message or the HTML structure as needed. Save and Test: Save the changes to your functions.php file and visit your WordPress site to test the shortcode. When a user is logged in, it should display a personalized greeting with their name. Remember to be cautious when editing theme files, and always keep a backup before making changes. If you're not comfortable editing code directly, consider using a child theme to avoid losing your modifications during theme updates.
