Strange error messages, help me please?

scotty99 · August 23, 2008

Within my website I have an RSS feed which the news page uses to display up to date news. What I want is for a form to be placed in the restricted area so members of staff can add to the RSS feed without any technical knowledge. The RSS feed is located here. The news page is here.

Here is the code which I was given:

<?php
// Local location of newsfeed file
$feed_file = "http://www.crieffaircadets.org.uk/newsfeed.xml";

// Some Channel Variables - Editable
$channel_title = "38 (Crieff) DF - News Channel";
$channel_description = "Keep up to date with the latest news about the flight.";
$channel_link = "http://www.crieffaircadets.org.uk/newsfeed.xml";

// Array to hold feed items - do not edit
$channel_items = array();

// Placeholder for error messages - do not edit
$message = "";
$message_class = "";

// If the form submit button (btnSubmit) was pressed
if(isset($_POST['btnSubmit']))
{
   // Values from the form
   $title = trim($_POST['txtTitle']);
   $desc = trim($_POST['txtDesc']);
   
   // If both fields were not empty
   if(!empty($title) && !empty($desc))
   {
      // If magic quotes are enabled on your server, counter it 
      if(get_magic_quotes_gpc())
      {
         $title = stripslashes($title);
         $desc = stripslashes($desc);      
      }
   
      // Get the current RSS Feed
      $xml = new SimpleXMLElement($feed_file, null, true);

      // Add the new item to the channel_items array
      $channel_items[] = array(
            "title" => $title,
            "description" => $desc,
            "link" => "http://www.crieffaircadets.org.uk/news.php#start",
            "guid" => date("Y-M-d-H-i-s-") . rand(0,100),
            "pubDate" => date("D, d M Y H:i:s") . " +0000"         
      );
               
      // Read the current items within the feed and add them to the channel_items array
      foreach($xml->channel->item as $item)
      {
         $channel_items[] = array(
            "title" => $item->title,
            "description" => $item->description,
            "link" => $item->link,
            "guid" => $item->guid,
            "pubDate" => $item->pubDate
         );      
      }
               
      // Rewrite the XML RSS file
      if($new_file = fopen($feed_file, "w"))
      {
         // Channel tags
         $rss = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\r\n";
         $rss .= "<rss version=\"2.0\">\r\n";
         $rss .= "  <channel>\r\n";
         $rss .= "    <title>" . $settings['site_name'] . "</title>\r\n";

            $rss .= "    </item>\r\n";               
         }
         
         $rss .= "  </channel>\r\n";
         $rss .= "</rss>";
         
         // Physically write the content to the feed file
         fwrite($new_file, $rss);
         fclose($new_file);
         
         $message_class = "message-good";
         $message = "The news item was added successfully.";

I think this error

URL file-access is disabled in the server configuration

pretty much sums it up...

Change the server settings...

You host is has turned off file access using URLs. Talk to them.
