    I am having trouble understanding why I cannot include a callback on the action hook ‘widgets_init’ in my plugin’s index.php from another file using include(‘path’)like I normally do .
    Generally , to keep my index.php file of my plugin clean I include callbacks like below

    include( 'includes/init.php' );
    add_action( 'init', 'recipe_init' );

    But for the ‘widgets_init’ hook I cannot directly include like below :

    include( '/includes/widgets.php' );
    add_action( 'widgets_init', 'r_widgets_init' );

    Which thorws an error :

    Warning: include(/includes/widgets.php): failed to open stream: No such file or 
    directory in C:\xampp\htdocs\clean1\wp-content\plugins\recipe2\index.php on line 29
    Warning: include(): Failed opening '/includes/widgets.php' for inclusion 
    (include_path='C:\xampp\php\PEAR') in C:\xampp\htdocs\clean1\wp-content\plugins
    \recipe2\index.php on line 2 :

    Instead something like below works :

    include( dirname(RECIPE_PLUGIN_URL) . '/includes/widgets.php' );
    add_action( 'widgets_init', 'r_widgets_init' );

    I checked the functions.php of my theme and there we seem to be able to include a
    callback on the same hook directly :

    include( get_theme_file_path( '/includes/widgets.php' ) );
    add_action( 'widgets_init', 'ju_widgets' );

    I am curious as to why it doesnt work in case of plugins while in the theme it
    works ? I checked and found ‘widgets_init’ hook to be trigerred pretty late
    after ‘plugins_loaded’ hook is fired so all my plugin code should be available by
    the time ‘widgets_init’ is fired or am I misunderstanding how WP loads ?

    I’d advise against using relative paths for anything WP related. Your code will be more robust and reliable when you use full absolute paths built from functions like plugin_dir_path().
