php - 如何使用获取页面树在 OctoberCMS 中获取静态页面下拉列表？

Question

我是根据我在 OctoberCMS 的静态页面中的静态页面下拉列表中自己的评论中的问题打开这个的。

添加 $pageList->getPageTree(true) 时出现问题。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;
        });
    });
}

感谢是否有人可以提供帮助。

可能这会对你有所帮助。

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"
]

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

对于您的代码

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);
        }        
    }    
}
