如何在drupal 7中列出当前父页面的所有子页面？ [英] How to list all child pages of current parent page in drupal 7?

问题描述

假设我有父页面A1和B1。 A1有子页面A1.1，A1.2，A1.3和B1有子页面B1.1，B1.2。我想在A1和B1上列出所有相应的子页面。在每个孩子页面中，我都有一个图像和标题。这两个信息需要在父页面上以预告片的形式列出。我需要帮助，无论是通过编码还是使用意见，我不介意，只要我得到正确的结果。谢谢

解决方案

您可以通过创建显示所需字段或预告片的视图来实现这一点。然后在过滤器值不可用的过滤器的配置中添加内容Nid上下文过滤器，选择提供默认值，然后选择PHP代码，然后我使用的代码如下

  $ children = array（）; 
 $ current = db_query（select menu_name，mlid from {menu_links} where link_path =：node，array（'：node'=> $ _GET ['q']））; 
 $ current_info = array（）; 
 foreach（$ current as $ value）{
 $ current_info [] = $ value; 
} 
 if（$ current_info）{
 $ result = db_query（select mlid，plid，link_path，link_title from {menu_links} where menu_name =：menu and plid =：mlid and hidden = 0 order by，link_title，array（'：menu'=> $ current_info [0]  - > menu_name，'：mlid'=> $ current_info [0]→> mlid））; 
 foreach（$ result as $ row）{
 $ children [] = $ row; 
} 
} 
 $ nids = array（）; 
 foreach（$ children as $ value）{
 if（substr（$ value-> link_path，0，5）=='node /'）{
 $ nids [] = substr （$ value-> link_path，5）; 
} 
} 
 return implode（'+'，$ nids）; 
  

最后一件事情，在页面底部的更多sellect允许多个值

Suppose I have parent pages A1 and B1. A1 has child pages A1.1, A1.2,A1.3 and B1 has child pages B1.1, B1.2. I want to list all the respective child pages on A1 and B1. In every child page I have an image and a title. These 2 information needs to be listed in the form of a teaser on the parent page. I need help in doing this whether by coding or by using views, I don't mind as far as I get the proper results. Thank you

解决方案

You can do this is views by creating a view displaying the fields you require or a teaser. Then add a "Content Nid" contextual filter, in the configeration for this filter under "WHEN THE FILTER VALUE IS NOT AVAILABLE" select "Provide default value" and then "PHP Code" then the code I use is as follows

$children = array();
$current = db_query("select menu_name, mlid from {menu_links} where link_path = :node", array(':node' => $_GET['q']));
$current_info = array();
foreach ($current as $value) {
$current_info[] = $value;
}
if($current_info) {
$result = db_query("select mlid, plid, link_path, link_title from {menu_links}    where menu_name=:menu and plid=:mlid and hidden=0 order by weight, link_title", array(':menu' => $current_info[0]->menu_name, ':mlid' => $current_info[0]->mlid));
foreach ($result as $row) {
  $children[] = $row;
}
}
$nids = array();
foreach ($children as $value){
if( substr( $value->link_path, 0, 5 ) == 'node/' ){
  $nids[] = substr( $value->link_path, 5 );
}
}
return implode('+',$nids);

The last thing to do, under "more" at the bottom of the page sellect "Allow multiple values"
