我正在处理WordPress上传元字段。当用户上传图像时，图像的大小是二维的，一个是“拇指”，一个是“大”，它们的大小调整得非常完美。我使用不同的元键在数据库中保存两个图像维度路径，如下所示：

对于拇指图像wpc_resize_thumb_图像和大图像wpc_resize_big_图像

当我在DB中保存图像路径时，它保存得非常完美

以下是我在DB中保存它们的代码：

用于大图像

$wpc_resize_big_images = get_post_meta($post->ID, 'wpc_resize_big_images', true);
echo "<pre>";
    print_r($wpc_resize_big_images);
echo "</pre>";

Array
(
    [1] => Array
        (
            [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_55-500x375.jpg
        )

    [2] => Array
        (
            [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_51-500x333.jpg
        )
)

    [1] => Array

            [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_55-500x375.jpg
        )

[2] => Array
    (
        [wpc_resize_thumb_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_51-212x141.jpg
        [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_51-500x333.jpg
    )
)

在数据库中，它将按如下方式保存：

meta_键

wpc_调整大小_大_图像

在数据库中，它将按如下方式保存：

当我打印它们时，它们会显示如下结果：

拇指图像

现在我的问题是，如何用一个元键合并并保存两个维度到数据库中，当我打印元键时，它会给出这样的结果

我想要这个

$wpc_resize_big_images = get_post_meta($post->ID, 'wpc_resize_big_images', true);
echo "<pre>";
    print_r($wpc_resize_big_images);
echo "</pre>";

Array
(
    [1] => Array
        (
            [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_55-500x375.jpg
        )

    [2] => Array
        (
            [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_51-500x333.jpg
        )
)

Array
(
    [1] => Array
        (
            [wpc_resize_thumb_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_55-212x159.jpg
            [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_55-500x375.jpg
        )

[2] => Array
    (
        [wpc_resize_thumb_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_51-212x141.jpg
        [wpc_resize_big_img] => http://localhost/test/wp-content/uploads/2015/06/Wallpaper_51-500x333.jpg
    )
)

保存多维数组时，可以使用以下代码：

这样，您就可以获得所需的多维数组：

我有两种选择。。1）不要

保存

，然后再

合并

。。保存已合并的文件。2）创建一个新表行并分配一个

id

，例如。。。（两者相同），然后可以在查询中使用

join

命令。
