EDIT: Original answer was inaccurate as you can do this with wp_update_post and the meta_input field

根据更新后的问题和评论，这可以通过wp_update_post （或wp_insert_post 对于新记录），使用meta_input 在阵列上键入，例如：

$metaValues = array(
    \'key1\' => \'value1\',
    \'key2\' => \'value2\', 
    //   ... as many key/values as you want
);

wp_update_post(array(
            \'ID\'        => $postId,
            \'meta_input\'=> $metaValues,
));

Original Answer （如上述选项所示，这样做是可行的，但没有意义）

没有。The docs 清楚地显示功能不支持这一点。

显然，如果您同时有许多事情要做，那么可以使用数组来传递许多值。

这是一个PHP编程问题，不是Wordpress问题，但代码如下所示：

$postId = 1234;

// Perhaps you have multiple key value pairs, like this:
$metaValues = array(
    \'key1\' => \'value1\',
    \'key2\' => \'value2\', 
    //   ... as many key/values as you want
);

// Set all key/value pairs in $metaValues
foreach ($metaValues as $metaKey => $metaValue) {
    update_post_meta($postId, $metaKey, $metaValue);
}

或者这只是为了更新多个键上的值：

// Or maybe you want to update a bunch of keys with the same value for some reason..
$metaValue = "10";
$metaKeys = Array("key1", "key2"); // as many keys as you want here

foreach($metaKeys as $metaKey) {
    update_post_meta($postId, $metaKey, $metaValue);
}
