Topic: [HACK] import RSS feed in CuteNews
Name: Import RSS feed in CuteNews
Author: FUNimations
CuteNews Compatibility: 1.3.6 - * (no incompatibility reported yet)
Description: Reads an rss feed and imports the news items into CuteNews. Feeds are saved in CuteNews, any changes made to the original post won't be noticed by CuteNews!! This hack makes use of a public script. The license agreement etc. can be found in one of the files you'll have to make.
The feed will be loaded each time you visit the Cn panels main page.
Requirements: RSS2.0 feed
Instructions:
open shows.inc.php find
$output = str_replace("[link]","[url=]", $output);add above
if( substr($news_arr[4], 0, 5) == "<RSS>" )
$output = str_replace("[link]","<a target=\"_blank\" href=\"".substr($news_arr[4], 5)."\">", $output);
else
find 2 times
if($config_comments_popup == "yes"){
$output = str_replace("[com-link]","<a href=\"#\" onclick=\"window.open('$config_http_script_dir/show_news.php?subaction=showcomments&template=$template&id=$news_arr[0]&archive=$archive&start_from=$my_start_from&ucat=$news_arr[6]', '_News', '$config_comments_popup_string');return false;\">", $output);
replace with
if( substr($news_arr[4], 0, 5) == "<RSS>" )
$output = preg_replace("'\\[com-link\\].*?\\[/com-link\\]'si","<!--rss feed can't be commented-->", $output);
elseif($config_comments_popup == "yes"){
$output = str_replace("[com-link]","<a href=\"#\" onclick=\"window.open('$config_http_script_dir/show_news.php?subaction=showcomments&template=$template&id=$news_arr[0]&archive=$archive&start_from=$my_start_from&ucat=$news_arr[6]', '_News', '$config_comments_popup_string');return false;\">", $output);
open functions.inc.php and find
///////////////////////////////////////////////////////
// Function: formatsize
// Description: Format the size of given fileadd above
///////////////////////////////////////////////////////
// Function: ResynchronizeRSS
// Description: Auto-Adds rss
function AutoSyncRSS()
{
require_once './inc/rssReader.php'; // include library
include './inc/rssImportFunction.mdu';
}
open the CuteNews index.php and find
if($mod == ""){ require("./inc/main.mdu"); }replace with
if($mod == ""){ require("./inc/main.mdu");AutoSyncRSS(); }
Make a new file called rss_update.db.php, put it in the data folder and chmodd to 777.
make a new file called rssReader.php and, put it in the inc folder. Add the following code to the file<div class='codetop'>CODE</div><div class='codemain' style='height:200px;white-space:pre;overflow:auto'><?php
/**
* Rss Feed Reader
*
* After two years, I decided to rewrite and fix this
* class. Thanks to all of you who sent me bug reports
* and sorry that I didn't replied. I'm lazy when it
* comes to talking.
*
* Changelog v2.1:
* - added Text parser support. Got this idea today
* while working on something else. Maybe help in
* some cases where XML and SimpleXML fails. To be
* honest, it's not really the finest solution but
* it works and I was too tired to think more about
* it...
*
* Changelog v2.0:
* - new version, hopefully without stupid bugs
* if left in first version 
* - added SimpleXML parser support
*
* Bugs:
* - Opening local files won't work for some reason,
* probably because of headers or something. Using
* SXML or TXT instead of XML may help.
*
* Issues:
* - Because of some PHP configurations deny to open
* remote files with fopen(), I used file_get_contents()
* but you still can switch to fopen(). See code for
* more informations.
*
* Usage:
* - See example.php
*
* Notes:
* - If you study this code a little, you can see that
* SXML is just a little wrapper around very few lines
* of code. SimpleXML is really nice and simple way to
* parse XML, but it has problems with special chars
* entities.
* - Even that this class is released under GPL licence,
* I'm not responsible for anything that happens to you
* (e.g. you die by reading these dull lines of text)
* or your computer/website/whatever.
