从PHP循环中生成XML文件 [英] Generate an XML file out of a PHP loop

问题描述

我正在为FAQ进行实时搜索，为此，我需要一个XML文档，用于存储实时搜索建议.

I am building a livesearch for a FAQ and in order to do so, I need an XML document where the livesearch suggestions will be stored.

问题在于FAQ会经常更新，我不想每次都碰代码.

The problem is that the FAQ will be updated often and I don't want to have to touch the code every time.

因此，我试图制作一个PHP文件，当我们打开它时会生成一个新的XML文件.由于不同文件夹中有许多常见问题解答项目，因此我需要脚本自动在特定目录中查找所有常见问题解答项目. FAQ项存储在TXT文件中，该文件存储在使用数字作为文件名(1、2、3等)的目录中，因此我可以轻松地添加/修改/删除它们.

Therefore, I am trying to make a PHP file that generates a new XML file when we open it. Since there are many FAQ items in different folders, I need that the script automatically finds all the FAQ items in a certain directories. The FAQ items are stored in TXT files which are stored in directories that use numbers as filenames (1, 2, 3, etc) so I can add/modify/delete them with ease.

路径如下所示: faqs/professionals/1/question.txt 或 faqs/professionals/2/question.txt 用于第二个常见问题解答项目或 faqs/students/1/question.txt 用于另一个主题中的常见问题解答项目.

A path would look like this: faqs/professionals/1/question.txt or faqs/professionals/2/question.txt for a second FAQ item or faqs/students/1/question.txt for a FAQ item in a different topic.

例如，如果我想添加一个新的常见问题解答项目，我只需创建一个文件夹，假设为"3"，然后在其中添加2个文本文件( question.txt 和 answer.txt ).然后，我将运行PHP脚本，以便XML文件将考虑到新的常见问题解答项目"3"来更新建议.

For example, if I wanted to add a new FAQ item, I would just create a folder, let's say "3", and add 2 text files inside (question.txt and answer.txt). Then, I would run the PHP script so the XML file would update the suggestions, taking into account the new FAQ item "3".

我能够创建一个基于TXT文件内容构建XML文件的脚本.但是，我无法使其检测"所有文件夹(FAQ项所在的位置)并将它们添加到XML文件中.

I was able to make a script that builds the XML file based on the content of the TXT file. However, I am not able to make it "detect" all the folders (where the FAQ items are) and add them to the XML file.

该脚本基于以下页面: w3schools.com/php/php_ajax_livesearch.asp

The script is based on this page: w3schools.com/php/php_ajax_livesearch.asp

这是代码:

<?php 
foreach (glob("../faqs/professionals/*",GLOB_ONLYDIR) as $x) {
  $pages = array(); 
  $pages [] = array( 
  'title' => file_get_contents($x.'/question.txt'), 
  'url' => dirname($x),
  );   
}

  $doc = new DOMDocument(); 
  $doc->formatOutput = true; 

  $r = $doc->createElement( "pages" ); 
  $doc->appendChild( $r ); 

  foreach( $pages as $link ) 
  { 
  $b = $doc->createElement( "link" ); 

  $title = $doc->createElement( "title" ); 
  $title->appendChild( 
  $doc->createTextNode( $link['title'] ) 
  ); 
  $b->appendChild( $title ); 

  $url = $doc->createElement( "url" ); 
  $url->appendChild( 
  $doc->createTextNode( $link['url'] ) 
  ); 
  $b->appendChild( $url ); 

  $r->appendChild( $b ); 
  } 

  echo $doc->saveXML(); 
  $doc->save("links.xml") 
  ?>

一旦该脚本开始运行，当我们单击建议时，我将尝试使实时搜索在文本输入下方显示answer.txt的内容.但这已经是另一个问题了……

Once this script will be working, I will try to make the livesearch display the content of answer.txt below the text input when we click on a suggestion. But this is already another problem...

任何帮助将不胜感激. :)

Any help will be greatly appreciated. :)

推荐答案

我认为问题在于，当您构建第一个$pages数组时，您会使用dirname($x).这是目录的目录名称.因此，glob()返回的路径为faq/professionals/1，并以该目录名命名，最后得到faq/professionals.

I think the problem is that when your building up the first $pages array, your using dirname($x). This is taking the directory name of the directory. So glob() is returning a path of faq/professionals/1 and your taking the directory name of this, you end up with faq/professionals.

所以我认为您需要更改的只是URL的设置...

So I think all you need to change is the setting of the url...

$pages [] = array(
   'title' => file_get_contents($x.'/question.txt'),
   'url' => $x
);
