如何在后元中保存一个元键的数组？

时间：2011-08-06 作者：Jenny

我在postmata中保存了一个数组，每个数组键都成为一个元键。我想更改代码，用一个元键保存整个数组。如何做到这一点？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。仅使用update_post_meta($post_ID, {key}, {array of vals}), 应该可以！

<?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);
?>
就是这样！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。

结束
