View Full Version : Advanced RSS Ticker Problem

08-09-2006, 02:51 PM
1) Script Title: Advanced RSS Ticker (Ajax Invocation)

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/rsstickerajax/index.htm

3) Describe problem: I'm trying to get the RSS Ticker to work and like several others on the message board can get the demo to work but am getting "Error fetching remote RSS feed!" when I try to add other feeds. It does not say "Sorry: It's not possible to reach RSS file ..." as others have posted. I'd post a link but I am currently only trying it out on a laptop with IIS. Following a suggestion on another post I checked to make sure that allow_url_fopen is on and it is. Because I am using a windows system I cannot set the cache directory to "chmod 777." Is there a way to do this in Windows? Could this be my problem?

I'm also getting two notices: "Notice: Undefined index: lastBuildDate in c:\inetpub\wwwroot\lastrss\lastRSS.php on line 159"


"Notice: strtotime() [function.strtotime]: Called with empty time parameter in c:\inetpub\wwwroot\lastrss\lastRSS.php on line 159."

if that helps.

The directory structure I have set up is:

Here is my bridge.php


LastRSS bridge script- By Dynamic Drive (http://www.dynamicdrive.com)
Communicates between LastRSS.php to Advanced Ajax ticker script using Ajax. Returns RSS feed in XML format
Created: Feb 9th, 2006. Updated: Feb 9th, 2006

header('Content-type: text/xml');

// include lastRSS
include "lastRSS.php"; //path to lastRSS.php on your server from this script ("bridge.php")

// Create lastRSS object
$rss = new lastRSS;
$rss->cache_dir = 'cache'; //path to cache directory on your server from this script. Chmod 777!
$rss->date_format = 'M d, Y g:i:s A'; //date format of RSS item. See PHP date() function for possible input.

// List of RSS URLs
"LRC_News" => "http://ntcclibrary.wordpress.com/feed/",
"CNN" => "http://rss.cnn.com/rss/cnn_topstories.rss",
"BBC" => "http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml",

////Beginners don't need to configure past here////////////////////

$rssurl=isset($rsslist[$rssid])? $rsslist[$rssid] : die("Error: Can't find requested RSS in list.");

// -------------------------------------------------------------------
// outputRSS_XML()- Outputs the "title", "link", "description", and "pubDate" elements of an RSS feed in XML format

function outputRSS_XML($url) {
global $rss;
$cacheseconds=(int) $_GET["cachetime"]; //typecast "cachetime" parameter as integer (0 or greater)
$rss->cache_time = $cacheseconds;
if ($rs = $rss->get($url)) {
echo "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n<rss version=\"2.0\">\n<channel>\n";
foreach ($rs['items'] as $item) {
echo "<item>\n<link>$item[link]</link>\n<title>$item[title]</title>\n<description>$item[description]</description>\n<pubDate>$item[pubDate]</pubDate>\n</item>\n\n";
echo "</channel></rss>";
if ($rs['items_count'] <= 0) { echo "<li>Sorry, no items found in the RSS file :-(</li>"; }
else {
echo "Sorry: It's not possible to reach RSS file $url\n<br />";
// you will probably hide this message in a live version

The only line I changed in rssticker.js is the URL.

//Relative URL syntax:
var lastrssbridgeurl="../lastrss/bridge.php"

I did not make any changes to lastRSS.php but I can post the code for it and all of rssticker.js if you feel that they would be helpful.

The feed I tried adding is http://ntcclibrary.wordpress.com/feed/

its ok :p just thought to be thorough :cool: well, i guess u dont need to post the lastRSS.php and rssticker.js if u ddnt make any change with these two files :p

//Relative URL syntax:
var lastrssbridgeurl="lastrss/bridge.php"

without the "../" :cool:
should work, i think. dont ask me why that works. i dunno either. i just tried removing it and the RSS Ticker works just fine. tnx. :p

08-09-2006, 07:27 PM
Thanks for the suggestion. Suprisingly, I made the change in the code and nothing changed. The reason I originally added the ../ to the code is because the javascript file is in a subdirectory of the directory demo.htm is in so it has to drop back a directory before hitting the lastrss directory. Any other suggestions?

08-09-2006, 08:50 PM
the change that i gave out works fine on my local webserver so i thought it might work for you too :p

Any other suggestions?
anyway, that's about it :cool:
