我正在使用设置API存储所有选项：

function registerSettings() {

register_setting(\'XX_theme_settings\', \'XX_theme_settings\', \'setting_validate\' );

add_settings_section(\'theme_options\', \'Theme Options\', \'theme_options_generate\', \'page1\' ); 
add_settings_field( \'XX_Option1\', \'Option 1\', \'text_input\', \'page1\', \'theme_options\', \'XX_Option1\' );
add_settings_field( \'XX_Option2\', \'Option 2\', \'text_input\', \'page1\', \'theme_options\', \'XX_Option2\' ); 

};

add_action(\'admin_init\', \'registerSettings\');

假设我想手动更新所有选项（不是使用表单，而是通过PHP），我应该怎么做？

对于一个设置，此更新就是这样的：

$my_options= get_option(\'XX_theme_settings\');//retrieve all options
$my_options[\'XX_Option2\'] = \'my new value\'; //amend value in array(s)
update_option(\'XX_theme_settings\', $my_options); //update option array

我完全不知道如何使它适用于多个（最初我有50多个）设置字段。

我一直在这样尝试：

$current_options = get_option(\'XX_theme_settings\');
$imported_options = array_merge($current_options , array_intersect_key($_POST["import"], $current_options ));
// $imported_options = $_POST["import"]; - simplified
update_option(\'XX_theme_settings\', $imported_options);

当然，“import”不是一个字符串，而是一个数组。

这里有一个相关的（我自己的）问题：Settings API - how to update options manually?

我想我仍然需要创建一个PHP foreach循环并循环所有设置，然后列出它们，然后通过update\\u选项添加每个设置？如何操作？它会很慢吗，因为它听起来很慢？

UPDATE

此代码似乎没有更新设置：

$current_options = get_option( \'XX_theme_settings\', array() );
$desired_options = array("existing_field" => "new value");
// $desired_options = array("XX_theme_settings" => array("existing_field" => "new value")); tried this one, but also no luck
$merged_options = wp_parse_args( $current_options, $desired_options );
update_option( \'XX_theme_settings\', $merged_options );

UPDATE II

这更奇怪。

我把上面的代码放在第页。php（仅出于测试原因）：

    $current_options = get_option( \'XX_theme_settings\', array() );
    $desired_options = array("existing_field" => "new value");
    $merged_options = wp_parse_args( $current_options, $desired_options );
    update_option( \'XX_theme_settings\', $merged_options );

我刷新其中一页。什么都没发生。然后我将代码更改为：

    $current_options = get_option( \'XX_theme_settings\', array() );
    $desired_options = array("existing_field" => "new value");
    $merged_options[] = wp_parse_args( $current_options, $desired_options ); //here\'s the change
    update_option( \'XX_theme_settings\', $merged_options );

另一次刷新，“existing\\u field”现在是emtpy。

然后，我再次粘贴第一个代码，并第三次刷新，结果一切正常。

提示：也许我应该在更新字段之前删除字段值？

$current_options = get_option( \'option_name\', array() );

$desired_options = array( /* whatever you need goes here */ );

$merged_options = wp_parse_args( $current_options, $desired_options );

update_option( \'option_name\', $merged_options );

$desired_options = array( $_POST[\'import\'] );
