将第二个自定义分类添加到自定义帖子类型(两者都显示在其表中)？

时间：2011-02-06 作者：janoChen

以下代码由提供Mike Schinkel, 创建自定义帖子类型和自定义分类法。它使分类显示在自定义帖子类型的列中。最后，它插入了一些默认术语。

我想为自定义帖子类型（页面内容）插入第二个分类法，名为：Locations.

（第二个自定义分类法也应显示在自定义帖子类型的列中）

我如何修改代码来存档它？

EDIT (What I\'ve done so far with no PHP skills):

通过修改代码，到目前为止我已经做到了：

I\'m still struggling with this line:

   function manage_page_content_posts_columns($columns){
     $new = array();
     foreach($columns as $key => $title) {
       if ($key==\'author\') // Put the Page Sections column before the Author column
         $new[\'locations_column\'] = \'Locations\';
         $new[\'cb\'] = \'<input type="checkbox">\';
         $new[\'title\'] = \'Title\';
         $new[\'page_sections_column\'] = \'Page Sections\';
       $new[$key] = $title;
     }
     return $new;
   }

I can\'t manage to place Page Sections before Locations.

如何解决这个问题？

最合适的回答,由SO网友:Zack 整理而成

我在过滤器挂钩中使用以下内容manage_edit-<post-type>_columns

add_filter( \'manage_edit-visitor_columns\', array( &$this, \'_wp_filter_visitor_columns\' ) );

public function _wp_filter_visitor_columns( $columns )
{
    $columns = array(
            \'cb\' => \'<input type="checkbox" />\',
            \'title\' => \'Name\',
            \'type\' => \'Type\',
            //\'state\' => \'Current State\',
            \'id\' => \'Visitor ID\',
            \'acct\' => \'Using Account\',
        );

    return $columns;
}
为了过滤列视图，我使用以下方法：

add_action( \'manage_posts_custom_column\', array( &$this, \'_wp_filter_visitor_column_view\' ) );

public function _wp_filter_visitor_column_view( $column )
{
    global $post;
    if ( $column == "type" )
    {
        //$terms = get_the_term_list( $post->ID, \'v_types\', \'\', \', \', \'\' );
        //echo strip_tags( $terms );

        $terms = wp_get_object_terms( $post->ID, \'v_types\' );
        echo $terms[0]->name;
    }
    elseif ( $column == "state" OR $column == "workstation" )
    {
        $workstation = get_post_meta( $post->ID, \'v_workstation\', true );
        if ( $column == "workstation" ) echo $workstation;
        elseif ( $column == "state" ) echo \'Not coded....\';
    }
    elseif ( $column == "id" )
    {
        echo get_post_meta( $post->ID, \'v_id\', true );
    }
    elseif ( $column == "acct" )
    {
        $terms = wp_get_object_terms( $post->ID, \'v_accounts\' );
        echo $terms[0]->name;
    }
}
我希望这对你有帮助。

结束
