这不起作用：

警告：in\\u array（）要求参数2为数组，给定null

$non_area_page = array(160951,160955); // This does not work

add_filter( \'term_link\',change_term_name , 10, 3 );  
function change_term_name( $termlink, $term, $taxonomy )
{
   /*If on page */
    if(is_page()){
        $current_id = get_queried_object_id();
        $current_post = get_post($current_id);
        $slug = $current_post->post_name; 
        if(!in_array($current_id,$non_area_page)) // array is defined in start of code above
        $termlink = esc_url( add_query_arg( [\'tag\' => $slug], $termlink ) );

    }          
    return  $termlink;
}

下面的代码起作用：（唯一的区别是数组没有在函数外定义）

add_filter( \'term_link\',change_term_name , 10, 3 );
function change_term_name( $termlink, $term, $taxonomy )
{
   /*If on page */
    if(is_page()){
        $current_id = get_queried_object_id();
        $current_post = get_post($current_id);
        $slug = $current_post->post_name; 
        if(!in_array($current_id,array(160951,160955))) // directly passed array
        $termlink = esc_url( add_query_arg( [\'tag\' => $slug], $termlink ) );

    }        
    return  $termlink;
}

这是否与全局定义数组有关，如果是，请建议我们如何在WordPress中这样做？

谢谢

funtion get_global_array()
{
    // Return an array with values 1, 2 and 3
    return [1, 2, 3];
}
