Code
add_action( 'pre_get_posts', function ( $query ) {
global $pagenow;
if ( ! is_admin() || ! $query->is_main_query() || 'edit.php' !== $pagenow ) {
return;
}
$post_type = $query->get( 'post_type' ) ? $query->get( 'post_type' ) : 'post';
$object = get_post_type_object( is_array( $post_type ) ? reset( $post_type ) : $post_type );
if ( $object && ! current_user_can( $object->cap->edit_others_posts ) ) {
$query->set( 'author', get_current_user_id() );
