Function and usage of get_raw_theme_root() in wordpress


Answers ( 1 )


    The get_raw_theme_root() function in WordPress is used to retrieve the raw theme root directory relative to the content directory. This function is particularly useful when you need to access the theme directory without any modifications or filters applied to the path.

    Function Signature

    get_raw_theme_root( string $stylesheet_or_template, bool $skip_cache = false ): string


    1. $stylesheet_or_template (string, required): This parameter specifies the stylesheet or template name of the theme. It's essential for identifying the specific theme whose root you're interested in.

    2. $skip_cache (bool, optional): Determines whether to bypass the WordPress cache when retrieving the theme root. This can be useful if you're concerned about receiving outdated information due to caching. The default value is false, which means the function will use cached data if available.

      • Default: false

    Return Value

    • string: The function returns the theme root directory as a string. This value represents the path of the theme directory relative to the content directory of your WordPress installation.

    Usage Example

    Let's say you want to find the root directory of a theme named "mytheme". Here's how you might use get_raw_theme_root():

    $theme_name = "mytheme";
    $theme_root = get_raw_theme_root($theme_name);
    // Optionally, you can choose to skip the cache
    $theme_root_no_cache = get_raw_theme_root($theme_name, true);
    echo "The theme root is: " . $theme_root;
    echo "The theme root without cache is: " . $theme_root_no_cache;

    In this example, $theme_root will hold the path to the "mytheme" directory relative to the content directory, using the cached data if available. $theme_root_no_cache, on the other hand, will fetch the same information but bypassing the cache.

    Practical Applications

    • Theme Development: Useful for theme developers who need to programmatically access the theme directory.
    • Debugging: Helpful in troubleshooting theme-related issues, especially when dealing with caching problems.
    • Custom Plugins: Can be used in custom plugins that need to interact with different themes based on certain conditions.


    • It's important to use this function carefully, especially when deciding to skip the cache, as it might impact performance.
    • The function is part of WordPress's core functionality, so it should be available in standard installations without the need for additional plugins or libraries.
