same user role or copy the user role to be same as the other role

Question

how do you make the user role "contributor" to be same as the user role "seller" by using functions.php

I've tried user role editor, but it seems to be the dokan multivendor plugin has set only into user role "seller" but I wanted to make the "contributor" to be same as the seller role

Answer 1

Contributor has the following capabilities

• delete_posts
• edit_posts
• read

You can create the "Seller" role to have same capabilities as Contributor

add_role(
    'seller',
    __( 'Seller' ),
    array(
        'read'         => true,
        'edit_posts'   => true,
        'delete_posts' => true,
    )
);

Warning from codex

NB: This setting is saved to the database (in table wp_options, field wp_user_roles), so it might be better to run this on theme/plugin activation

In functions.php, you should use this in after_setup_theme hook.

EDIT

You can also create a user role who have same permission as another this way

add_role(
    'specialuser',
    __('Special User'),
    get_role('seller')->capabilities
);

It will grant specialuser same capabilities as seller.
