(solved) getting post author's user role

Question

we can use

$user = wp_get_current_user();
    if ( !in_array( 'administrator', (array) $user->roles ) )

to get the user role of the viewer. but i want to ignore who views. i want to get who writes the post. need something like

$user = wp_get_post_author();
    if ( !in_array( 'administrator', (array) $user->roles ) )

so that i can show results depending on the user who writes the post while ignoring who views that.

Answer 1

You can find the author's ID on the post and fetch their user object from that with get_userdata(), e.g.

$author = get_userdata( get_post()->post_author ) ;
if ( !in_array( 'administrator', (array) $author->roles ) ) { ... }

Answer 2

I tried so hard and got so far But in the end it doesn't even matter

$post_id = get_queried_object_id();
$author_ID = get_post_field( 'post_author', $post_id );
$authorData = get_userdata( $author_ID );
if ( !in_array( 'administrator', $authorData->roles)){... ...}

Answer 3

Retrieve the current user object from the wp_get_current_user() and then check administrator role in in_array.

$user = wp_get_current_user();
if ( in_array( 'administrator', (array) $user->roles ) ) {
    //The user has the "administrator" role
}

Here I have shared the link for wp_get_current_user() and in_array() for better understanding.
