如何在postmeta中使用一个metakey保存数组？

我有一个保存在postmata中的数组，每个数组键都成为一个元键。我想更改代码以使用一个metakey保存整个数组。怎么做？谢谢！

$poddata = Array(
'pod_id' => $this->pod_id,
'url' => $this->url,
'name' => $this->name,
'description' => $this->description,
'service' => $this->service,
'status' =>$this->status,
'price' => $this->price
);

foreach ( $poddata as $k => $v ){

if ( get_post_meta( $this->id, $k ) == '' )
add_post_meta( $this->id, $meta_box, $v, true );

elseif ( $v != get_post_meta( $this->id, $k, true ) )
update_post_meta( $this->id, $k, $v );

elseif ( $v == '' )
delete_post_meta( $this->id, $k, get_post_meta( $this->id, $k, true ) );

}

您不需要遍历这些值。只需使用update_post_meta($post_ID, {key}, {array of vals})，它就应该做！

<?php
$poddata = Array(
    'pod_id' => $this->pod_id,
    'url' => $this->url,
    'name' => $this->name,
    'description' => $this->description,
    'service' => $this->service,
    'status' =>$this->status,
    'price' => $this->price
    );

//Update inserts a new entry if it doesn't exist, updates otherwise
update_post_meta($post_ID, 'poddata', $poddata);
?>

而已！当您获取它以供使用时，请执行以下操作：

    $poddata = get_post_meta($post_ID, 'poddata');

$ poddata是值的数组。
