SimplePie is a PHP library can greatly simplify the retrieval and manipulation of RSS feeds, or, more generally, to XML formats. You can, for example, write a few lines of code, exploiting some "funzioncina" jQuery to create a News Ticker to join our site / blog.
What we need ...
First of all download SimplePie and place, somewhere, the file simplepie.inc on your site / blog. The code to read and display a feed is as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | / ** * Sample SimplePie * * @ Author Giovambattista Fazioli * @ Web http://www.undolog.com * @ @ Email g.fazioli undolog.com * * / / / Insert the correct path "simplepie.inc" ) ; require_once ("simplepie.inc"); / / $c , $l ) { wordCut function ($ c, $ s) { explode ( ' ' , $c ) ; $ A = explode ('', $ c); count ( $a ) > $l ) { if ( count ($ a)> $ l) { $i = 0 ; $i < $l ; $i ++ ) $r [ $i ] = $a [ $i ] ; for ($ i = 0; $ i <$ l $ i + +) $ r [$ i] = $ a [$ i]; implode ( ' ' , $r ) . '...' ; $ R = implode ('', $ r).'...'; ; return $ r; $c ; Else return $ c}; } / / 10 ; // last 10 post/news $ Max = 10, / / last 10 posts / news new SimplePie ( 'http://www.undolog.com/feed' ) ; $ Thefeed = new SimplePie ('http://www.undolog.com/feed'); handle_content_type ( ) ; $ Thefeed -> handle_content_type (); $i = 0 ; $i < $thefeed -> get_item_quantity ( $max ) ; $i ++ ) $articles [ ] = $thefeed -> get_item ( $i ) ; for ($ i = 0; $ i <$ thefeed -> get_item_quantity ($ max); $ i + +) $ articles [] = $ thefeed -> get_Item ($ i); $articles as $item ) echo '<li><a href="' . $item -> get_link ( ) . '">' . $item -> get_title ( ) . '</a> - ' . wordCut ( $item -> get_description ( ) , 10 ) . '</li>' ; foreach ($ articles as $ item) echo '<a href="' <li>. $item -> get_link ().' "> '. $ item -> get_title ().' </ a> - '. wordCut ($ item -> get_description (), 10). '</ li>'; |
In this sample code I extracted from the last 10 feeds undolog.com and I have a list formatted using ul/li . ). I have regained the title is ( $item->get_title() ) that a part of the contents ( $item->get_description() ). Of course, enter this code inside a HTML formatting like this:
1 2 3 4 5 |
We come now to the JavaScript to view "turns", with a simple animation, individual titles / content feeds:
1 2 3 4 5 6 7 8 9 | / / Include jQuery through Google API "text/javascript" src = "http://www.google.com/jsapi" >< / script > < script type = "text / javascript" src = "http://www.google.com/jsapi"> </ script > "text/javascript" > google.load("jquery", "1.2.6"); < / script > < script type = "text / javascript"> google.load ("jquery", "1.2.6") </ script > <! - JQuery code for entertainment news -> "text/javascript" src = "sample.js" >< / script > < script type = "text / javascript" src = "Sample.js"> </ script > "text/javascript" > < script type = "text / javascript"> / / Call initNews () the completion of the page google.setOnLoadCallback (initNews); </ script > |
In the file sample.js , you can call and place where you want, we have:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 | / / Global 0 ; index_news var = 0; / / initNews function () { ) $ ('Div # feed-ticker') 'slow' , . SlideDown ('slow', function () { ) . eq ( index_news ) . fadeIn ( ) ; $ ('Div # ticker-feed them'). Eq (index_news). FadeIn (); 5000 ) ; setTimeout (next_news, 5000); } ); } next_news function () { ) $ ('Div # ticker-feed them') index_news ) . Eq (index_news) 1000 , . FadeOut (1000, function () { index_news + +; index_news > $ ( 'div#feed-ticker li' ) . length - 1 ) index_news = 0 ; if (index_news> $ ('div # ticker-feed them'.) length - 1) = 0 index_news; ) . eq ( index_news ) . fadeIn ( ) ; $ ('Div # ticker-feed them'). Eq (index_news). FadeIn (); 5000 ) ; setTimeout (next_news, 5000); } ); } |

As it happens I was just recently implemented a feed reader for the management of notifications to be sent to customers of e-commerce application, this class in PHP I greatly speed up work, then use it for the addition of some effect in jQuery.
PS Undolog wanted to report an error on the link to Saidmade.com
@ MaiNick:

I took your code and tried to IT implementations but I am getting errors.
The php code on line 10 PHP has
require_once ( "simplepie.inc");Which Gives me an error.And if I remove the "simplepie.inc", it gives me again the foe an error / / in the next line.
Please let me know if I am doing anything wrong.
@ Manju: You have to download SimplePie library before test your code. Follow the instruction in post.
