Ice IT Support Posted August 8, 2011 Share Posted August 8, 2011 Hi, I would like to make an RSS feed reader on my site using PHP. I tried using the W3School's tutorial (http://www.w3schools.com/Php/php_ajax_rss_reader.asp), but I don't want users to select an rss feed. I tried to modify the scripts myself, but PHP returned multiple errors. I have tried a few RSS widgets such as Google and Feedwind, but they either didn't display the feed or didn't display the text correctly. I searched Softaculous as well, but the RSS scripts they have doesn't provide the functionality I am looking for. Quote Link to comment Share on other sites More sharing options...
Guest Geoff Posted August 9, 2011 Share Posted August 9, 2011 PHP File: <?php //get the q parameter from URL $q=$_GET["q"]; //find out which feed was selected if($q=="RSS") { $xml=("http://path.to/your/feed.xml"); } $xmlDoc = new DOMDocument(); $xmlDoc->load($xml); //get elements from "<channel>" $channel=$xmlDoc->getElementsByTagName('channel')->item(0); $channel_title = $channel->getElementsByTagName('title') ->item(0)->childNodes->item(0)->nodeValue; $channel_link = $channel->getElementsByTagName('link') ->item(0)->childNodes->item(0)->nodeValue; $channel_desc = $channel->getElementsByTagName('description') ->item(0)->childNodes->item(0)->nodeValue; //output elements from "<channel>" echo("<p><a href='" . $channel_link . "'>" . $channel_title . "</a>"); echo("<br />"); echo($channel_desc . "</p>"); //get and output "<item>" elements $x=$xmlDoc->getElementsByTagName('item'); for ($i=0; $i<=2; $i++) { $item_title=$x->item($i)->getElementsByTagName('title') ->item(0)->childNodes->item(0)->nodeValue; $item_link=$x->item($i)->getElementsByTagName('link') ->item(0)->childNodes->item(0)->nodeValue; $item_desc=$x->item($i)->getElementsByTagName('description') ->item(0)->childNodes->item(0)->nodeValue; echo ("<p><a href='" . $item_link .

Ice IT Support Posted August 9, 2011 Author Share Posted August 9, 2011 Thanks for your reply! I tried the code(s) above and here is what happened... The HTML file doesn't display my feed staffsites.iceitsupport.net/wheeler_jonathon/index.html and I think it's because PHP returns these errors staffsites.iceitsupport.net/wheeler_jonathon/rss.php Warning: DOMDocument::load() [domdocument.load]: Empty string supplied as input in /home/iceitsup/public_html/Other/StaffSites/wheeler_jonathon/rss.php on line 12 Fatal error: Call to a member function getElementsByTagName() on a non-object in /home/iceitsup/public_html/Other/StaffSites/wheeler_jonathon/rss.php on line 16 Quote Link to comment Share on other sites More sharing options...

Guest Geoff Posted August 9, 2011 Share Posted August 9, 2011 Looks like it's working now. Quote Link to comment Share on other sites More sharing options...
Ice IT Support Posted August 9, 2011 Author Share Posted August 9, 2011 Oops! Sorry about that! I found a less complicated script that ran for a while then it started giving errors as well. I then cleared my cache and it works for now. Quote Link to comment Share on other sites More sharing options...
