我有一个自定义帖子类型，它有一个标题和两个元框自定义字段

$price = isset( $we_productMetas[\'price_box\'] ) ? esc_attr( $we_productMetas[\'price_box\'][0] ) : \'\';
$color = isset( $we_productMetas[\'color_box\'] ) ? esc_attr( $we_productMetas[\'color_box\'][0] ) : \'\';

我在CSV文件中有一些数据是这种格式的

title,price,color
Item1,50,red
Item2,20,green
Item3,60,red
Item4,10,blue

使用以下代码，我能够加载title 并发布CSV，但我缺少price 和color 元数据

你能看一下这个演示并告诉我我做错了什么吗

      $post["id"] = wp_insert_post( array(
                "post_title" => $post["title"],
                "post_type" => $cpt["custom-post-type"],
                "custom-field-1" =>$cpt["custom-field-1"],
                "custom-field-2" =>$cpt["custom-field-2"],
                "post_status" => "publish"
            ));

这是全部代码

add_action( "admin_notices", function() {
    echo "<div class=\'updated\'>";
    echo "<p>";
    echo "To insert the posts into the database, click the button to the right.";
    echo "<a class=\'button button-primary\' style=\'margin:0.25em 1em\' href=\'{$_SERVER["REQUEST_URI"]}&insert_cpt_posts\'>Insert Posts</a>";
    echo "</p>";
    echo "</div>";

        } else {

        }
    }

    if ( ! empty( $errors ) ) {

    }

    return $data;
};

$post_exists = function( $title ) use ( $wpdb, $cpt ) {

    };

    foreach ( $posts() as $post ) {

        }
