【问题描述】：

我是根据我在Static page dropdown within static page in OctoberCMS 的评论中提出的问题来打开这个的。

我在添加 $pageList->getPageTree(true) 时遇到问题。子页面未显示。我当前的代码是从 $pageObject->subpages 重复 foreach，这不是一个好习惯。

下面是我的代码示例：

插件.php

<?php namespace MyPlugin\CustomPlugin
use System\Classes\PluginBase;
public function boot() 
    \RainLab\Pages\Classes\Page::extend(function($model) 
        $model->addDynamicMethod('getPageOptions', function() 
            $theme = \Cms\Classes\Theme::getEditTheme();
            $pageList = new \RainLab\Pages\Classes\PageList($theme);
            $pages = [];
            foreach ($pageList->getPageTree(true) as $name => $pageObject) 
                $pages[$pageObject->page->url] = $pageObject->page->title;
                if ($pageObject->subpages) 
                    foreach ($pageObject->subpages as $name => $pageObject) 
                        $pages[$pageObject->page->url] = '&nbsp;&nbsp;&nbsp;' . $pageObject->page->title;
                        if ($pageObject->subpages) 
                            foreach ($pageObject->subpages as $name => $pageObject) 
                                $pages[$pageObject->page->url] = '&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;' . $pageObject->page->title;
                            
                        
                    
                
            
            return $pages;
        );
    );

如果有人可以提供帮助，不胜感激。

【参考方案1】：

也许这会对你有所帮助。

function onStart() 
    $theme = \Cms\Classes\Theme::getEditTheme();
    $pageList = new \RainLab\Pages\Classes\PageList($theme);    
    $treePageList = $pageList->getPageTree(true);    
    $pages = [];
    $this->getRecursivePage($pages, $treePageList);
    dd($pages);


function getRecursivePage(&$pages, $subpages, $level = 0)         
    $level++;
    foreach($subpages as $pageArr)         
        $pages[$pageArr->page->url] = 
               str_repeat('-',$level) . ' ' . $pageArr->page->title;                     
        if(count($pageArr->subpages) > 0)             
            $this->getRecursivePage($pages, $pageArr->subpages, $level);
                
        

输出

array:9 [▼
  "/content" => "- Content"
  "/content/pages" => "-- Static Pages"
  "/content/content" => "-- Content"
  "/content/models" => "-- Models"
  "/content/urls" => "-- URLs"
  "/content/urls/tesets" => "--- tesets"
  "/test-sp" => "- test-sp"
  "/test-sp/oks" => "-- oks"
  "/test" => "- test"
]

在这里您可以将- 替换为  或删除该部分[ I added because you had that in code so, may be useful to you. ]

为您的代码

public function boot() 
  \RainLab\Pages\Classes\Page::extend(function($model) 
      $model->addDynamicMethod('getPageOptions', function() 
          $theme = \Cms\Classes\Theme::getEditTheme();
          $pageList = new \RainLab\Pages\Classes\PageList($theme);
          $treePageList = $pageList->getPageTree(true);
          $pages = [];
          $this->getRecursivePage($pages, $treePageList);
          return $pages;
      );
  );


public function getRecursivePage(&$pages, $subpages, $level = 0)         
    $level++;
    foreach($subpages as $pageArr)         
        $pages[$pageArr->page->url] = 
               str_repeat('-',$level) . ' ' . $pageArr->page->title;                     
        if(count($pageArr->subpages) > 0)             
            $this->getRecursivePage($pages, $pageArr->subpages, $level);

嗨，代码似乎在子页面后不起作用。 imgur.com/a/0Tazzmm子页面循环后所有父页面都变成子页面

hmm，更新了getRecursivePage() 方法请使用新方法，现在应该可以了。
