我創建了一個畫廊崗位類型（作爲一個插件的一部分），包含除了標題和一些元信息也wp_list_table，查詢那些具有當前崗位作爲post_parent附件。當我的發佈按鈕突然停止工作時，我遇到了一個問題。無論我是否創建一個新的畫廊，或者如果我正在編輯一箇舊的畫廊，一旦我點擊更新/發佈，我的更改就會丟失，最終我會在edit.php。
有人知道這是什麼意思？WordPress的自定義文章類型 - 打破發布按鈕
我在哪裏可以找出問題的癥結所在。它在我的list_table類中，它繼承自wp_list_table。在評論出一些不重要的功能後，我最終得到了一個不同的錯誤，但仍然沒有新的或更新的圖庫。現在我得到are you sure you want to do this頁面。
即使是最基本的類將無法正常工作......
if(! class_exists('WP_List_Table')) {
require_once(ABSPATH . 'wp-admin/includes/class-wp-list-table.php');
}
class Yard_Attachment_Table extends WP_List_Table {
function __construct() {
global $status, $page;
parent::__construct(array(
'singular' => 'yard Attachment',
'plural' => 'yard Attachments',
'ajax' => false
));
}
function column_default($item, $column_name) {
return 'default';
}
function get_columns(){
$columns = array(
'checkbox' => '<input type="checkbox" />', //for simplicity its not 'cb'
'thumb' => 'Thumbnail',
'title' => 'Titel',
'pos' => 'Position'
);
return $columns;
}
function prepare_items() {
global $wpdb;
$columns = $this->get_columns();
$hidden = array();
$sortable = $this->get_sortable_columns();
$this->_column_headers = array($columns, $hidden, $sortable);
if (isset($_REQUEST['post'])) {
$query = " SELECT *
FROM $wpdb->posts
WHERE post_type = 'attachment'
AND post_parent = {$_REQUEST['post']}";
$data = $wpdb->get_results($query, ARRAY_A);
} else {
$data = array();
}
$this->items = $data;
}
}
在插件類的構造函數我用
add_action('add_meta_boxes_yard_gallery', array($this, 'yard_metaboxes'));。
在yard_metaboxes我使用add_meta_box和功能我有一個回調我創建我的表類的實例new，我打電話prepare_items()和display()
轉向使用error_reporting我的網頁上有這些消息去世：
Strict Standards: Only variables should be passed by reference in /Applications/MAMP/htdocs/Web/ChristophRokitta/wp v.1.0/wp-includes/pomo/mo.php on line 210

BTW我沒有本地化。
請幫忙！如果我有更多的聲譽，我會提供。
加元框代碼

您的問題出在您的Meta Box代碼中，但是您顯示的Table類代碼似乎與發佈操作無關...... – brasofilo
@brasofilo幾乎是整個代碼。我希望你能找到一分鐘來看看 – yardarrat
有點不可告人，因爲你發佈的代碼不是[SSCCE]（http://sscce.org/）。檢查[this]（https://github.com/brasofilo/Internal-Link-Check）以獲得擴展'WP_List_Table'並將其用作元框回調的示例。 – brasofilo
