Not able to show the add_menu_page icon

Question

I am working a plugin development. I want to show an icon on the menu Page. I am using the following code :

add_menu_page('pms_rohitashv','PMS','subscriber','pms_rohitashv-main', plugin_dir_url( __FILE__ ).'icon.png');

I am using the plugin icon size 16X16 but the icon shown on the menu is gear icon. I want to change it with the custom icon.

What mistake I am making in the code

Answer 1

You have added the directory name where do you have stored the icon and this should be the 6th argument rather than 5th.

add_menu_page(
    'pms_rohitashv',
    'PMS',
    'subscriber',
    'pms_rohitashv-main',
    '', 
    plugin_dir_url( __FILE__ ).'/images/icon.png'
);
