How To: Get news on your site via RSS / PHP

[developmy.mobi]

I saw a thread on here where someone needed a little guidance on how to get a news feed to show news on their site.

This is a very basic way, it will not archive the news, but it will show it on your site, and the users wont have to leave or view through google.

Only 1 variable needs to be changed:

$feed_url = "http://feed.url"; // change to the feed you wish to use!

Here is the code:

<?
$feed_url = "http://feed.url" // change to the feed you wish to use!

class RSSParser {

   var $insideitem = false;
   var $tag = "";
   var $title = "";
   var $description = "";
   var $link = "";

   function startElement($parser, $tagName, $attrs) {
       if ($this->insideitem) {
           $this->tag = $tagName;
       } elseif ($tagName == "ITEM") {
           $this->insideitem = true;
       }
   }

   function endElement($parser, $tagName) {
       if ($tagName == "ITEM") {

           
           print "
           <b>" . $this->title . "</b>
           <div class=\"text\">" . $this->description . "<br /><a href=\"" . $this->link . "\" target=\"_blank\">Read the Rest of This Story</a></div><br />";
            
           $this->title = "";
           $this->description = "";
           $this->link = "";
           $this->insideitem = false;
           

       }
   }

   function characterData($parser, $data) {
       if ($this->insideitem) {
           switch ($this->tag) {
               case "TITLE":
               $this->title .= $data;
               break;
               case "DESCRIPTION":
               $this->description .= $data;
               break;
               case "LINK":
               $this->link .= $data;
               break;
           }
       }
   }
}
    
    $xml_parser = xml_parser_create();
    $rss_parser = new RSSParser();
    xml_set_object($xml_parser,&$rss_parser);
    xml_set_element_handler($xml_parser, "startElement", "endElement");
    xml_set_character_data_handler($xml_parser, "characterData");
    $fp = fopen("$feed_url","r")
       or die("Error reading RSS data.");
    while ($data = fread($fp, 4096))
       xml_parse($xml_parser, $data, feof($fp))
           or die(sprintf("XML error: %s at line %d",  
               xml_error_string(xml_get_error_code($xml_parser)),  
               xml_get_current_line_number($xml_parser)));
    fclose($fp); 
    
    xml_parser_free($xml_parser);
    

?>

This code is very affective, although I have found that it doesnt EVER work well with google feeds for some reason. So if anything use Yahoo over Google.

Enjoy, and if you have any questions I'm here to answer them.

Thank you very much DevelopeMy.mobi
Rep added!

[Scandiman]

Thanks DM! This input is much appreciated!

[developmy.mobi]

No problem!

[coast]

This is great. Rep Added.

P.S. Have you tried it and does it work with the .mobi standards?

[noonoo1]

How do you get the rss feed to show on your website. I am just not getting it and i am going nuts

[bondjpf]

How can i use it on my html page?

[developmy.mobi]

You save your HTML page as a .php page and it should work.

[bondjpf]

So you're saying :

Insert this code into my code and then save the page as php?

Or create a new file with this code only?

[developmy.mobi]

Insert it into your current page wherever you want the new feed.

[bondjpf]

Hi,
So What I do is insert this code into my html page and then save itqth php extension.
Then I just need to make a link from my main page(index.html) to this new.php page ?

[noonoo1]

I still cant get it to work either, i tried php and html it just will not do it

[bondjpf]

Maybe it's your host that its configurated for windows.
I'm using godaddy windows hosting and it doeasn't work.
I have made my site using javascript http://capitalnews.mobi .
It doesn't work on most mobiles but i don't know how to do it withou changing hosting.
Maybe with v3 of mobisitegalore it will work ok.

[noonoo1]

I use hostgator.

PHP can work on a windows server, but you have to inform with your hosting company which dynamic language they support (if they do...). My hosting company doesn't support php but asp(.net)...and there is no way I can use the code above on my sites...

Please note, there is supposed to be a ; after $feed_url = "your url";

It shows up in the editor, but not on here.

Hey it works!!! i love you i love you i love you

It didnt work in html but it did work in php.

[bondjpf]

It gives me :

Error reading RSS data.

[developmy.mobi]

use a Yahoo feed - google feeds tend to suck with this code.

[pilot]

Got similar code for asp? thanks developmy!

[developmy.mobi]

GijsZePa might, I'm a LAMP guy.

[pilot]

GijsZePa, where you at?!

GijsZePa might, I'm a LAMP guy.

[GijsZePa]

Here I am..had to go into my archives because I don't work with classic asp anymore...(try asp.net Pilot...it will blow you away)

The rss-writer (you can publish rss with this code. Wrote this myself):

NOTE: change the session.lcid=1043 into your own country code...

<%@ Language=VBScript %>
<%option explicit%>
<% 
session.lcid=1043
Response.ContentType = "text/xml"
 
DIM adoCon, adoRec
Function ApplyXMLFormatting(strInput)
 
  strInput = Replace(strInput,"&", "&amp;")
  strInput = Replace(strInput,"'", "&apos;")
  strInput = Replace(strInput,"""", "&quot;")
  strInput = Replace(strInput, ">", "&gt;")
  strInput = Replace(strInput,"<","&lt;")
  ApplyXMLFormatting = strInput
 
End Function 
 
 
Function StartConnection()
 
    Dim strCon
    strCon =     "<your connection>"
    Set adoCon = Server.CreateObject("Adodb.COnnection") 
    adoCon.Open strCon
    Set adoRec = Server.CreateObject( "ADODB.RecordSet")
    adoRec.ActiveConnection = adoCon
 
End Function
 
Function EndConnection()
 
    Set adoRec=Nothing
    adoCon.close
    Set adoCon=Nothing
 
End Function
 
 
'GetRows Method
 
Function GetRecords(strSQL)
 
    ' getrows 
    startConnection()
    adoRec.open strSQL, adoCon
    If Not (adoRec.BOF AND adoRec.EOF) Then
        GetRecords = adoRec.GetRows()
    End If
    adoRec.Close
    EndConnection()
 
End Function

<?xml version="1.0" encoding="ISO-8859-1" ?> 
<rss version="2.0">

<title>Mijn Rss Feed creator</title>

'Create rows
Dim intTeller, aArtikel, strSQL
strSQL = "SELECT nId, dDate, cTitle, cDescription FROM myArticles ORDER BY dDate DESC"
aArtikel = getRecords(strSQL)
 
If isArray(aArtikel) then
    For intTeller = 0 to Ubound(aArtikel,2)
        response.write "     <item>" & VbCrLf
        response.write "        <pubDate>" & aArtikel(1,intTeller) & "</pubDate>" & vbCrLf

        response.write "    </item>" & VbCrLf 
    Next 
 
End If
 
%> 
</channel> 
</rss>

And this is a reader method (grabbed this from the net):

<%
response.ContentType="text/html"
dim objXML, objXSL
set objXML=server.CreateObject("MSXML2.DOMDocument")
set objXSL=server.CreateObject("MSXML2.DOMDocument")
objXML.async=False
objXSL.async=False
objXML.setProperty "ServerHTTPRequest",true
objXML.load http://thefeed.com
objXSL.load Server.MapPath("rssStyle.xslt")
response.write "<html><head><title>RSS Feed Reader</title></head><body>"
response.write objXML.transformNode(objXSL)
response.write "</body></html>"
set objXML=nothing
set objXSL=nothing
%>

And this is the XSLT file (named rssStyle.xslt)

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="html" omit-xml-declaration="yes" />
 <xsl:template match="/rss/channel">
    <b><xsl:value-of select="title" disable-output-escaping="yes" /></b>
    <xsl:for-each select="item">
       <li>
          <a>
             <xsl:attribute name="href">
                <xsl:value-of select="link" />
  </xsl:attribute>
             <xsl:attribute name="target">_blank</xsl:attribute>
             <xsl:value-of select="title" disable-output-escaping="yes"  />
          </a>
          (<xsl:value-of select="pubDate" />)
       </li>
    </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

For customizing the Feed layout simply change the XSLT file!

Oh...and for the asp.net programmers...just follow this link...cool toolkit:

[bondjpf]

Can you tell me where do I put the first code?
Thanks

[GijsZePa]

Can you tell me where do I put the first code?
Thanks

Well..where you want in your site...

example: cut and past the code into a new asp file: for example articles.asp in your root: www.site.com/articles.asp

People can use that url as RSS source in their readers or websites..

Martin

[italiandragon]

does this work for .com sites too ?

Thanks

[GijsZePa]

does this work for .com sites too ?

Thanks

It works on every site..but depends on your platform.
You have to check with your hosting company if or which dynamic platform they support..

I have some php code that is small, very easy to put in your code, it uses require once to get the rest of the code from another file (the read rss code) and then displays it (display code). The page that has the display code has to be php5, the other (read) file can be php4 or 5, let me know if you'd like the code...


Oh PS
