WordPress Filter – Get Username

I am using a plugin that gives me the option to customize a specific sentence through wordpress filter.

This is the orginal code:

add_filter('filter_stamper_text_after_replacing_tags', 'customize_text_to_stamp', 10, 2);

function customize_text_to_stamp ($text_to_stamp, $additional_params) 
{

    $text_to_stamp .= "Adding this test message to the stamping test";

    return $text_to_stamp;
}

I need to insert current-username in the $text_to_stamp, so it returns like:

$text_to_stamp .= "Some text here" . Current-Username. "some text here";

This sentence is only displayed if there is a logged in user, so this verification is not necessary.

I dont know how to get the current username and how to insert it into the sentence.

Can you help me?

Try the below code that will help you.

add_filter('filter_stamper_text_after_replacing_tags', 'customize_text_to_stamp', 10, 2);

function customize_text_to_stamp ($text_to_stamp, $additional_params) 
{

    $current_user = wp_get_current_user();

    // Which you want to dispaly you can set below type
    
    // $current_user->first_name   //First Name of login User
    // $current_user->last_name    //Last Name of login User
    // $current_user->display_name // Display name of login User

    $text_to_stamp .= "Some text here" . $current_user->user_login . "some text here";

    return $text_to_stamp;
}
