我在wp_options 当前存储为多维数组的表(profile_element_order):

a:12:{s:17:"img_base64_enable";s:1:"1";s:25:"moulding_combination_page";s:0:"";s:24:"moulding_collection_page";s:0:"";s:25:"idea_gallery_thumb_height";s:3:"200";s:24:"idea_gallery_thumb_width";s:3:"200";s:23:"collection_thumb_height";s:3:"200";s:22:"collection_thumb_width";s:3:"200";s:20:"profile_item_columns";s:1:"4";s:17:"idea_item_columns";s:1:"2";s:24:"collections_item_columns";s:1:"2";s:25:"combinations_item_columns";s:1:"4";s:21:"profile_element_order";a:5:{i:0;s:8:"Option 1";i:1;s:8:"Option 2";i:2;s:8:"Option 3";i:3;s:8:"Option 4";i:4;s:8:"Option 5";}}

我要做的是更新profile_element_order 选项（在这些选项中）。到目前为止，一切都是这样：

function psort_save_order() {

    global $mouldings_options;

    $list = $mouldings_options[\'profile_element_order\'];
    $new_order = $_POST[\'list_items\'];
    $new_list = array();

    // update order
    foreach($new_order as $v) {
        if(isset($list[$v])) {
            $new_list[$v] = $list[$v];
        }
    }

    // save the new order
    update_option(\'profile_element_order\', $new_list);

    die();
}
add_action(\'wp_ajax_psort_update_order\', \'psort_save_order\');

数据正确地发布到DB表中（因为我可以将一些失败的尝试视为新的选项条目，如mouldings_settings->profile_element_order) -- 我只是很难弄清楚update_option() 仅用于该特定选项的语法。我尝试过这样的方法（记住“Moldings\\u settings”是实际选项名称）：

mouldings_settings[\'profile_element_order\']
$mouldings_options[\'profile_element_order\']
profile_element_order

但目前没有骰子。任何指点都将不胜感激！谢谢

Update这就是我现在所拥有的--ajax操作保存得很好，但当我保存插件选项时，它会复制数据库中的选项，并抛出与之前相同的错误：

a:17:{s:17:"img_base64_enable";s:1:"1";s:25:"moulding_combination_page";s:0:"";s:24:"moulding_collection_page";s:0:"";s:25:"idea_gallery_thumb_height";s:3:"200";s:24:"idea_gallery_thumb_width";s:3:"200";s:23:"collection_thumb_height";s:3:"200";s:22:"collection_thumb_width";s:3:"200";s:20:"profile_item_columns";s:1:"4";s:17:"idea_item_columns";s:1:"2";s:24:"collections_item_columns";s:1:"2";s:25:"combinations_item_columns";s:1:"4";s:21:"profile_element_order";a:5:{i:4;s:8:"Option 5";i:0;s:8:"Option 1";i:1;s:8:"Option 2";i:3;s:8:"Option 4";i:2;s:8:"Option 3";}i:0;s:8:"Option 5";i:1;s:8:"Option 1";i:2;s:8:"Option 2";i:3;s:8:"Option 4";i:4;s:8:"Option 3";}

功能：

function psort_save_order() {

    global $mouldings_options;

    $list = $mouldings_options[\'profile_element_order\'];
    $new_order = $_POST[\'list_items\'];
    $new_list = array();

    // update order
    foreach($new_order as $v) {
        if(isset($list[$v])) {
            $new_list[$v] = $list[$v];
        }
    }

    $mouldings_options[\'profile_element_order\'] = $new_list;
    $mouldings_options = array_merge($mouldings_options,$mouldings_options[\'profile_element_order\']);

    // save the new order
    update_option(\'mouldings_settings\', $mouldings_options);

    die();
}
add_action(\'wp_ajax_psort_update_order\', \'psort_save_order\');

my_options = array(
  \'option_a\'=>\'value_a\',
  \'option_b\'=>\'value_b\',
  \'inner_array\'=>array(
       \'foo\' => \'bar\',
       \'hello\' => \'world\',
   ),
  \'option_c\'=>\'value_c\'
)

//Get entire array
$my_options = get_option(\'my_options\');

//Alter the options array appropriately
$my_options[\'inner_array\'][\'hello\'] = \'moon\';

//Update entire array
update_option(\'my_options\', $my_options);
