    The get_template() function in WordPress is a simple yet crucial function used to retrieve the name of the active theme. Here's a detailed explanation and a sample usage:

    Function:

    • get_template(): string

    Purpose:

    • The primary function of get_template() is to obtain the name of the currently active theme in a WordPress site.

    Return:

    • Type: string
    • Description: This function returns the template name as a string. It's important to note that this name corresponds to the theme's directory name, not its "pretty" name. For example, if your theme is in a directory named "twentytwenty", get_template() will return 'twentytwenty'.

    Sample Usage:

    Scenario:

    Suppose you are developing a WordPress plugin or a theme and you need to execute certain code only if a specific theme is active.

    Example Code:

    function check_current_theme() {
        $current_theme = get_template();
    
        if ($current_theme == 'my_custom_theme') {
            // Perform actions specific to 'my_custom_theme'
            echo "The 'my_custom_theme' is currently active.";
        } else {
            echo "The current theme is not 'my_custom_theme'.";
        }
    }
    add_action('wp_loaded', 'check_current_theme');
    

    Explanation:

    • In this sample, the check_current_theme function is defined.
    • It calls get_template() to get the name of the active theme.
    • The function then checks if the active theme is 'my_custom_theme'. If it is, it executes specific code (in this case, simply outputs a message).
    • The function is hooked to the 'wp_loaded' action, so it runs after WordPress is fully loaded.

    Key Points:

    • get_template() is useful for theme-specific functionality in plugins or functions.php.
    • It returns the directory name of the current theme, which is useful for conditional checks.
    • It does not return the "child theme" name if a child theme is being used. For that, get_stylesheet() is used instead.

    This function is a part of WordPress's theme architecture and is essential for developers who work on creating dynamic, theme-aware plugins and themes.
