Is there any function that would return the full path of my plugin in WordPress?

Example is

path/wp-contents/plugins/myplugin

I have tr

    Code For Plugin Root Path

    $dir = plugin_dir_path( __FILE__ );
    
    // Example: /home/user/var/www/wordpress/wp-content/plugins/my-plugin/
    

    Code for plugin path

    echo  WP_PLUGIN_DIR.'/plugin-name';

    You can gain it by using this method

    plugin_dir_url( __DIR__ )

    Kinda late to this party, but just in case some else stumbles upon this.

    plugin_dir_path(__FILE__) will always return the current path (where the file calling it is located).
    If you want the root, use the code below:

    plugin_dir_path( dirname( __FILE__ ) )
    

    You can then define a constant:

    define( 'YOUR_PLUGIN_DIR', plugin_dir_path( dirname( __FILE__ ) ) );
    require_once YOUR_PLUGIN_PATH . 'includes/admin-page.php'
    require_once YOUR_PLUGIN_PATH . 'admin/classes.php'

    plugins_dir_path() is a misnomer.
    It will always return the path to the current file.

    Link to the codex:
    https://developer.wordpress.org/reference/functions/plugin_dir_path/#more-information

    It is a wrapper for trailingslashit( dirname( $file ) );.

    The “plugin” part of the name is misleading – it can be used for any file, and will not return the directory of a plugin unless you call it within a file in the plugin’s base directory.

    It is actually synonym for the trailingslashit() function.

    IF the current file is in the plugins directory, then yes, the function returns the path of the current file.
    However, if you call this function from a file inside any other directory, then current file is not in the plugins directory, and thus it will does NOT return the path to the plugins directory. It does always return the path to the current file, but without a trailing slash.

    Most of the answers here are incorrect, or are only "sometimes" correct. Those answers will only work as they say IF your file happens to already be located in the plugins directory! In all other cases they will give you a misleading result: the path to your current file.


    It is more likely that your file is in a *subdirectory *of the plugins folder.

    If this is the case, this codex shows you how to create a URL to the current file: https://codex.wordpress.org/Function_Reference/plugins_url

    If you are using the plugins_url() function in a file that is nested inside a subdirectory of your plugin directory, you should use PHP's dirname() function:

    <?php echo '<img src="' . plugins_url( 'images/wordpress.png', dirname(__FILE__) ) . '" > '; ?>

    You would then need to remove your file name to get the path. Or use ``

    ANSWER:

    These solutions solutions are independant of where the file of your calling function is located. If your file is located in the plugins folder, or a subdirectory of it, then the above options would work. Otherwise, you'll need to resort to something along the lines of:

    WP_PLUGIN_DIR

    WordPress does have a constant defined, for the Plugins' folder:

    Codex: https://codex.wordpress.org/Determining_Plugin_and_Content_Directories

    Constants

    WordPress makes use of the following constants when determining the path to the content and plugin directories. These should not be used directly by plugins or themes, but are listed here for completeness.

    WP_CONTENT_DIR // no trailing slash, full paths only
    WP_CONTENT_URL // full url
    WP_PLUGIN_DIR // full path, no trailing slash
    WP_PLUGIN_URL // full url, no trailing slash

    // Available per default in MS, not set in single site install
    // Can be used in single site installs (as usual: at your own risk)
    UPLOADS // (If set, uploads folder, relative to ABSPATH) (for e.g.: /wp-content/uploads)


    Or, If you can guarantee that the plugins folder is located in the normal place for a WordPress install, i_a's answer above answer above will work, no matter what directory your file (that you want to call this function from) is in. Please see his more complete post in this thread, but so as to not have a "link only answer", I'll include here that it Essentially, it boils down to using the following (and turning it into a function):

    $plugins_root = WP_CONTENT_DIR . '/plugins';

    I would suggest to use a WordPress internal constant to solve this case:

    $my_plugin = WP_PLUGIN_DIR . '/my-plugin';
    
    if ( is_dir( $my_plugin ) ) {
        // plugin directory found!
    }
    

    Alternative

    The other valid alternative is to compute the path from the URL which is more complex/confusing. I would not use this code:

    $plugins_url = plugins_url();
    $base_url = get_option( 'siteurl' );
    $plugins_dir = str_replace( $base_url, ABSPATH, $plugins_url );
    // Now $plugins_dir is same as the WP_PLUGIN_DIR constant.
    
    $my_plugin = $plugins_dir . '/my-plugin';
    

    My opinion in this case is: Use the constant WP_PLUGIN_DIR

    Yeah as per description of plugin_dir_path it will give you current plugin file path. But as per what you asking here you can do something like below unfortunately no direct way,

    $plugin_dir = ABSPATH . 'wp-content/plugins/plugin-folder/';
