我正在尝试将自定义帖子元数据添加到自定义列。元框有两个文本字段，分别是Price和Company，但当我发布一篇新文章时，它只会在Price列和编辑框中显示Company的值，它还会在Price框中检索Company的值！您能告诉我为什么无法在自定义列中检索到正确的值吗？我是否在保存或检索数据时出错？

add_action(\'admin_init\', \'admin_init\');
add_action(\'save_post\', \'save_options\');
function admin_init(){
add_meta_box(
    "product_options",
    "product",
    "normal",
    "low"
  );
}

function product_opt(){
global $post;
$custom = get_post_custom($post->ID);
$price = $custom[\'price\'][0];
$coMake = $custom[\'coMake\'][0];

echo \'<label style="padding-right:40px;">Price:</label>
    <input name="price" value="\'. $price . \'" style="width:250px;" />\';

echo \'<p/ ><label style="padding-right:40px;">Company:</label>
    <input name="price" value="\'. $coMake . \'" style="width:250px;" />\';    
}

function save_options(){
global $post;
if (!isset($_POST[\'price\']) || $post->post_type != \'product\')
{
    return $post;
}
update_post_meta($post->ID, "price", $_POST[\'price\']);

if (!isset($_POST[\'coMake\']) || $post->post_type != \'product\')
{
    return $post;
}
update_post_meta($post->ID, "coMake", $_POST[\'coMake\']);
    }

          add_filter("manage_edit-product_columns", "edit_col" );
    add_action("manage_posts_custom_column", "custom_col");

    function edit_col($columns){
$columns = array(
    "cb" => "<input type =\'checkbox\' />",
    "title" => "Product Title",
    "price" => "Price",
    "coMake" => "Company",
    "type" => "Product Type" 
);
return $columns;
    }

    function custom_col($column)
    {
global $post;
switch ($column)
{
    case "price":
        $custom = get_post_custom($post->ID);
        echo $custom[\'price\'][0];
        break;
    case "coMake":
        $custom = get_post_custom($post->ID);
        echo $custom[\'coMake\'][0];
        break;
    case "type":
        echo get_the_term_list($post->ID, \'type\', \'\', \', \', \'\');
        break;
}
   }
