It would be nice, to have a RSS-Funktion for the Knowledgebase!

Is that possible in future version?

I am working on an RSS feed for tickets. But why would you want a feed for the KB?

Posted: **Tue Jan 26, 2010 1:14 pm**

cause we use it in Intranet and have round about 80 users who reads the KB AND who enters new storys.

So it would be nice to get the news via RSS

I whipped the following very rough stuff.
If you want me to, I can make it working and to your specs.

In your index.php place a link like this:

Code: Select all

<a type="application/rss+xml" href="rss.php"><img src="img/rss.png" alt="RSS feed for this site"></a>

I placed mine in inc/common.inc.php at around line 169 (Hesk 2.1). But you can put it anywhere. (I attached the rss.png

to this message).

rss.php

Code: Select all

<?php

hm, i got this error:

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\html\helpdesk\rss.php:1) in C:\xampp\htdocs\html\helpdesk\rss.php on line 2

Posted: **Thu Jan 28, 2010 9:19 am**

Delete the first empty line in rss.php (any lines or spaces before <?php )

Posted: **Thu Jan 28, 2010 9:46 am**

ok, i have removed now this line:

" header("Content-Type: application/xml; charset=ISO-8859-1"); "

FF shows the feed, but only with 2 articles

IE shows only an error.

Any hints?

Posted: **Thu Jan 28, 2010 9:52 am**

No, you misunderstood me - don't delete the "header" code. You have (or had) some empty lines or spaces before

Code: Select all

<?php

(not after), that was the cause of the error.

Posted: **Thu Jan 28, 2010 9:53 am**

hm, looks like it happens only in a local installation with XAMPP.

Online, the rss.php works fine....

Posted: **Thu Jan 28, 2010 9:54 am**

no, i have no empty lines before .... i looked for that in notepad ++.....

Posted: **Thu Jan 28, 2010 10:06 am**

So you don't get the "Warning: Cannot modify header information" error anymore?

Posted: **Thu Jan 28, 2010 10:11 am**

not online. Here all works fine.
http://www.wormserwebtreff.de/Helpdesk/rss.php

Locally with XAMPP in our intranet it dont works. Why ever....

IE says " Feed got errors" and FF shows only 2 articles in the feed.

Do you have any idea?

Posted: **Thu Jan 28, 2010 10:16 am**

seems to be an error with german "ä,ü,ö" etc.

Posted: **Thu Jan 28, 2010 10:48 am**

with the line "header" included:
Error:

Code: Select all

IE sucks, I won't even go there.

The SQL statement looks at the type of the article. Remove that from the sql statement and all articles should be visisble.

Code: Select all

$sql = 'SELECT `id`,`subject`, content FROM `'.hesk_dbEscape($hesk_settings['db_pfix']).'kb_articles` WHERE  `type`=\'0\' ORDER BY `views` DESC, `art_order` ASC LIMIT '.hesk_dbEscape($hesk_settings['kb_numshow']+1);

change it to:

Code: Select all

$sql = 'SELECT `id`,`subject`, content FROM `'.hesk_dbEscape($hesk_settings['db_pfix']).'kb_articles` WHERE id  ORDER BY `views` DESC, `art_order` ASC LIMIT '.hesk_dbEscape($hesk_settings['kb_numshow']+1);

btw: would it really hurt to say thank you?[/code]
