我有一个自己使用的自定义脚本/插件，可以创建一篇帖子以及一些Posteta信息。现在，我有多个$wpdb->insert, 但我想把它浓缩成一个问题。我该怎么做？

这是我当前的代码：

$meta_table = $wpdb->prefix . \'postmeta\';

    $wpdb->insert( 
    $meta_table, 
    array( 
        \'post_id\' => $post_id, // Already defined
        \'meta_key\' => \'client-pwd\',
        \'meta_value\' => $post_pwd // Already defined
        )
        );  

$wpdb->insert( 
    $meta_table, 
    array( 
        \'post_id\' => $post_id, 
        \'meta_key\' => \'gallery-status\',
        \'meta_value\' => \'private\'
        )
        );  

$wpdb->insert( 
    $meta_table, 
    array( 
        \'post_id\' => $post_id, 
        \'meta_key\' => \'meta-description\',
        \'meta_value\' => \'Description...\'
        )
        );  

$wpdb->insert( 
    $meta_table, 
    array( 
        \'post_id\' => $post_id, 
        \'meta_key\' => \'can-purchase\',
        \'meta_value\' => \'yes\'
        )
        );  

$wpdb->insert( 
    $meta_table, 
    array( 
        \'post_id\' => $post_id, 
        \'meta_key\' => \'can-email\',
        \'meta_value\' => \'yes\'
        )
        );  

$wpdb->insert( 
    $meta_table, 
    array( 
        \'post_id\' => $post_id, 
        \'meta_key\' => \'can-download\',
        \'meta_value\' => \'yes\'
        )
        );
