您可以删除这些功能delete_pages, delete_others_pages 和delete_published_pages 来自分配给用户的角色。这将阻止完整用户角色删除页面。

要将此行为仅限于一个用户，必须创建一个专用的新角色并将其分配给该用户。看看Members JustinTadlock插件，了解更多信息。

示例：从管理员角色中删除页面的功能

$role = get_role(\'administrator\');
$role->remove_cap(\'delete_pages\');
$role->remove_cap(\'delete_others_pages\');
$role->remove_cap(\'delete_published_pages\');

布莱恩·费特的答案几乎是完美的。

在我的测试中，只有将操作更改为“wp\\u trash\\u post”和“before\\u delete\\u post”时，他的答案才有效

function restrict_post_deletion($post_ID){
    $user = get_current_user_id();
    $restricted_users = array(21,25,54,2,19);
    $restricted_pages = array(2,21,52,64);
    if(in_array($user, $restricted_users) && in_array($post_ID, $restricted_pages)){
        echo "You are not authorized to delete this page.";
        exit;
    }
}
add_action(\'wp_trash_post\', \'restrict_post_deletion\', 10, 1);
add_action(\'before_delete_post\', \'restrict_post_deletion\', 10, 1);

您可以创建一个操作来限制用户丢弃或删除帖子，如下所示。这不是最漂亮的，但很管用。您必须手动填充用户和页面ID。

function restrict_post_deletion($post_ID){
    $user = get_current_user_id();
    $restricted_users = array(21,25,54,2,19);
    $restricted_pages = array(2,21,52,64);
    if(in_array($user, $restricted_users) && in_array($post_ID, $restricted_pages)){
        echo "You are not authorized to delete this page.";
        exit;
    }
}
add_action(\'trash_post\', \'restrict_post_deletion\', 10, 1);
add_action(\'delete_post\', \'restrict_post_deletion\', 10, 1);

以下是我测试并发现的一个示例，说明如何防止通过其ID删除特定帖子或页面。它应该适用于所有wordpress用户：

add_action(\'wp_trash_post\', \'prevent_post_deletion\');
function prevent_post_deletion($postid){
    $protected_post_id = 67586;
    if ($postid == $protected_post_id) {
        exit(\'The page you were trying to delete is protected.\');
    }
}

您可以很容易地从快速编辑和元框中隐藏垃圾箱链接。一个使用样式，另一个使用post\\u row\\u actions过滤器（您可以同时使用过滤器-dunno）https://developer.wordpress.org/reference/hooks/post_row_actions/

//hide meta with styles
function hide_publishing_actions()
{
    global $post;
    if ($post_id == 21)
    {
        if (!current_user_can(\'administrator\'))
        {
            // stuff here for non-admins
            echo \'<style type="text/css">#delete-action</style>\';
        }
    }
}

add_action(\'admin_head-post.php\', \'hide_publishing_actions\');
add_action(\'admin_head-post-new.php\', \'hide_publishing_actions\');

//for quick edit
add_filter(\'post_row_actions\', \'remove_row_actions\', 10, 1);
function remove_row_actions($actions)
{
    if (!current_user_can(\'administrator\'))
    {
        if ($post_id == 21)
        unset($actions[\'edit\']);
        unset($actions[\'view\']);
        unset($actions[\'trash\']);
        unset($actions[\'inline hide-if-no-js\']);
    }
    return $actions;
}

您还可以使用filter page\\u row\\u操作（请参阅https://developer.wordpress.org/reference/hooks/page_row_actions/) 对页面列表表中的每个页面调用。

您必须检查不希望编辑或删除的帖子的id。您可以修改这些页面的操作数组。如果返回空数组，页面仍将列在页面列表表中，但没有用于编辑、删除等的链接，。。。因此，无法编辑或删除该页面。

您的函数应该是这样的（注意：在我的示例代码中，只有站点管理员有权修改特殊页面）：

function custom_filter_page_row_actions($actions,$post){
  $page_to_exclude = get_page_by_path(Slug of the page you want to exclude);
  $site_admin_email = get_option(\'admin_email\'); // Get the email of the site admin
  $site_admin =  get_user_by(\'email\',$site_admin_email); // Get WP_User-instance of the site admin
  if(($post == $page_to_exclude) && ($site_admin != wp_get_current_user())){
    $actions = array(); //remove all actions
  }
  return $actions;
}
add_filter(\'page_row_actions\',\'custom_filter_page_row_actions\',999999,2); //Use a high number for this filter so that it is called after all plugins e.g. WPBakery Pagebuilder has add there actions
