Rename?
Whoops, didn't realize there was already an Extension called WikiFeeds out on Meta. In good conscious, I should rename this one. But to what? Now accepting suggestions. Thanks in advance. --Jimbojw 13:59, 5 January 2007 (UTC)


 * I haven't looked at the details of your extension, so if you can find a unique name that would be better, but if not we tend to use the username to distinguish, e.g. "WikiFeeds (Jimbojw)". --HappyDog 03:57, 8 January 2007 (UTC)


 * Thanks HappyDog - I'm thinking about renaming it to "ArticleFeeds" since that's essentially what it does: convert articles to feeds. --Jimbojw 18:02, 8 January 2007 (UTC)


 * Sounds good to me. --HappyDog 23:11, 8 January 2007 (UTC)


 * Done deal - just 'moved' it to Extension:WikiArticleFeeds. When the original WikiFeeds gets ported over from Meta, it can just overwrite the #REDIRECT --Jimbojw 19:47, 3 February 2007 (UTC)

getTitle Error when using version 1.8.2
I'm using MediaWiki 1.8.2 and I've installed the WikiFeeds extension. However, when creating a page using a simple example from the usage instructions, I get the following error: Fatal error: Call to a member function getTitle on a non-object in $IP/extensions/WikiFeeds.php on line 110

Has anyone experienced this? --Cmac4011 01:35, 21 January 2007 (UTC)


 * Thanks for trying out my extension. I unfortunately haven't tried this extension on any version other than 1.6.8 (my provider caps me at PHP 4).


 * I'll be happy to look into this as time permits. Are you getting this on page-preview? or after submitting the page?  I'm wondering if $wgArticle is not being populated for previewed pages.


 * --Jimbojw 18:31, 22 January 2007 (UTC)


 * Thanks sir. To answer your question, I'm getting this error when the published page is being rendered.  If you have any hunches or things you'd like me to try, I'd be glad to play around with the code in my PHP5 environment.


 * --Cmac4011 04:46, 24 January 2007 (UTC)


 * Hey Cmac - sorry for the delay, finally got around to fixing that issue. Turns out that in MW 1.8 and above, the $wgArticle global variable had not been initialized by the time the hooked methods were being executed.  The fix was to turn this line: $title = $wgArticle->getTitle; Into this line: $title = $wgTitle;  In any case, I've now tested on 1.6.8, 1.6.9, 1.8.3 and 1.9.1 - but not 1.8.2 explicitly.  I plan to support 1.6.x, 1.8.x and 1.9.x (as indicated on the extension page), so if you find that it's still acting up, please let me know.  Thanks!

Only shows one feed, the oldest on the list?
Thank you very much for this extension: exactly what I was looking for! Unfortunately I have two problems that completely elude me. I have MW version 1.7.1 and the page I am taling about is here Anyway I created a test page using only your example here I don't want to bother you but I you could point me to my mistake, if any, it would be so great! Thanks in any case! Guy gmalacrida at gmail.com EDIT: Thank you so much!
 * 1) Only the oldest (last on the list) item shows if you subscribe using the rss or atom links in the toolbox?
 * 2) Although my browser shows a feed icon in the address bar, clicking it opens a blank page with this in the address bar feed:http://www.yonis.ch/wiki/index.php?title=Actualit%C3%A9s&action=feed&feed=atom (NB: if you click on the link though, it will looks OK! You need click the rss icon in the address bar instead to replicate the problem. Also, Looking at the SpecialPages:Version the last line indeed indicates "UnknownAction: wfWikiFeedsAction" in the Hook section?).
 * Take all this away!
 * Just downloaded/installed last version 0.4 and my problems disapeared!


 * No worries - glad you like it! If you run into any more issues, I'll be glad to investigate.  Out of curiosity, how did you find my extension?  I'm always interested in hearing how people discover my creations.  Thanks again!

Object of class Title could not be converted to string
I'm using this extension on Mediawiki 1.9.3 and it appears there is a small bug which can be duplicated by doing the following.

Noopectro 14:47, 19 March 2007 (UTC)
 * 1) Create a template page, e.g. Template:Updates
 * 2) Add a few headers and text to the template and set up them up to work with WikiArticleFeeds
 * 3) Use the template in another page, E.g. on Main_Page.
 * 4) After using the template, the "RSS Atom" option should appear on the toolbox.
 * 5) Click RSS
 * 6) The following error appears: Catchable fatal error: Object of class Title could not be converted to string in /home/path/to/wiki/extensions/WikiArticleFeeds.php on line 266

EDIT: Turns out that somewhere between step 5 and saving this article, the Atom link does the same thing now too. EDIT.2: Even stranger is that some times it works as required, and some times it doesn't.


 * Thanks for bringing this to my attention, Noopectro. I have not yet been able to reproduce this issue (works for me).  I'm using PHP 5.1 in standard mode.  What version of PHP are you using?  Is your PHP running in Safe mode?
 * If you'd like to try something, change line 266 from this: $feed = new $wgFeedClasses[$feedFormat]($wgSitename.' - '.$title,, $title->getFullURL); To this: $feed = new $wgFeedClasses[$feedFormat]($wgSitename.' - '.$title->getText,, $title->getFullURL); Does this fix the issue? It continues to work for me with this change.
 * I just noticed something else too, it looks like updating an included template does not invalidate the parser cache in the way I would have expected, so updating the contents of a template will not necessarily make the next request for the including page's feed show the changes. I'll have to look into this more later to see if there's an easy fix.
 * --Jimbojw 18:33, 19 March 2007 (UTC)

For reference, i'm using PHP 5.2.1 (And Apache 2.2.4 if it makes a difference), and that small code change seems to of fixed it- thanks a lot. Hopefully this will help anyone else who was in the same situation as me. Noopectro 20:58, 19 March 2007 (UTC)


 * No worries! Glad we got it figured out.  By the way - I just released a new version of WikiArticleFeeds.  It contains this fix as well as some additional enhancement. --Jimbojw 23:00, 19 March 2007 (UTC)

Pb when create my fisrt feed
Hy,

i have installed release 0.6 of WAF (running on apache 2, php5, mediawiki 1.8.2) Installation is right and i create a new article as given into your examples.

I test with Firefox and when i try to register the feed by a right click on the RSS icon on the left of the URL toolbar, i have this error:

In english, it'a a firefox error whihc indicate the bad format for the xml output.

any idea ?

Thx --Ouaibsky 14:42, 26 March 2007 (UTC)


 * Hi Ouaibsky, if you could send me the generated XML file, I could take a look. Email: wilson.jim.r at gmail dot com --Jimbojw 16:52, 26 March 2007 (UTC)


 * Hello Jimbojw
 * Find below the source code of the generated page. Notes we have many blank line at the top of the result.

  2007-03-28T10:06:00Z MediaWiki 1.8.2 via WikiArticleFeeds 0.6


 * --Ouaibsky 10:08, 28 March 2007 (UTC)


 * I think it has something to do with the extra whitespace at the top. If you save the file locally and remove the whitespace, then open the file with FireFox, do you get the same result?  I believe the XML specification requires that the first line has to be: &lt;?xml version="1.0" encoding="utf-8"?&gt;


 * I'm not sure why the extra spaces are being inserted, and I haven't tested on 1.8.x recently (it works for me on 1.6.x and 1.9.x).


 * As a side note, you should re-download the WikiArticleFeeds.php file if you can - I just had to fix a bug this morning, so it's a good idea to get the latest instance. --Jimbojw 16:30, 28 March 2007 (UTC)


 * Update: I've seen this behavior myself now. It happens when there are trailing newlines at the end of extension files.  It may be that either my extension or others installed have trailing whitespace at the end of the included PHP files.  (Mine shouldn't - but copy-pasting the content with a text editor rather than downloading the raw source may result in this unintended consequence).


 * In my case, the extra newlines were in the DynamicPageList2 extension's i18n file. --Jimbojw 20:03, 18 April 2007 (UTC)

Warning messages in 0.6.1 when run in MediaWiki 1.9.3

 * Undefined index: 'href' WikiArticleFeeds.php on line 205
 * Undefined variable: wgSitename in WikiArticleFeeds.php on line 343

I changed line 205 from:

if (!$rssArr['href']) {

to:

if (!array_key_exists('href', $rssArr) || !$rssArr['href']) {

and I added above line 343:

global $wgSitename;


 * Thanks! I've implemented these bugfixes in the downloadable version on jimbojw.com.  I really apprecaite you taking the time to not only identify the problem, but provide a fix.  Thanks a bunch! --Jimbojw 19:59, 18 April 2007 (UTC)

error: Call-time pass-by-reference has been deprecated
Hello ! I'm really interested by your extension, however I can't get it to work. When I activate the extension (using mediawiki 1.10) I get this warning message:

'''Warning: Call-time pass-by-reference has been deprecated;  If you would like to pass it by reference, modify the declaration of [runtime function name]. If you would like to enable call-time pass-by-reference, you can set allow_call_time_pass_reference to true in your INI file. in /xxxx.org/html/testwiki/extensions/WikiArticleFeeds.php on line 150 '''

Do i really need to change a setting on the ini file or did I just made a stupid mistake (which is likely!) ???

thanks for your help

Lilious 13:29, 24 May 2007 (UTC)


 * Hi Lilious - I haven't seen that before, but it's probably because I'm running older versions of PHP (I suspect you're either using PHP 6 or PHP 5 under stricter rules like "safe mode"). I should refactor my code such that the function declaration itself defines whether the parameter is reference or value (not the other way around). --Jimbojw 16:08, 24 May 2007 (UTC)


 * Update: I've corrected this issue, Lilious. If you redownload the extension, I think you'll see the issue go away (though I haven't been able to reproduce your exact issue locally, so we'll have to wait and see).  Please let me know if this doesn't solve the problem.  Thanks! --Jimbojw 18:52, 24 May 2007 (UTC)

Bad format for the xml output & trailing newlines at the end of extension files
Hello;

In what extensions do you guess, could be the Trailing new lines that provoked a bad xml output format?. I have checked many of them and it remains one blank line at the beginning of the xml output file. I am using mediawiki 1.11.0 version--Jbujosa 11:52, 5 November 2007 (UTC)


 * Hello Jbujosa - see previous messages in this page on that topic. It's probably another extension which has additional leading or trailing whitespace in the file - either before the leading   or after the trailing  ?> </tt>. Good luck! -- Jimbojw 00:19, 11 December 2007 (UTC)

$wgWhitelistRead don't allow to access a page with a WikiArticleFeeds extension
I am working with version 1.11

In my wiki Anonymous users cant read pages: $wgGroupPermissions['*' ]['read'] = false;

I am trying to allow, feeds integrators, to access to pages that are built with the WikiArticleFeeds, using $wgWhitelistRead, but it doesn't work. Any one can help me?


 * Hello there. I'm sorry, but that doesn't make any sense.  If users can't read the page, why should they be able to get a feed of it? -- Jimbojw 00:19, 11 December 2007 (UTC)

error while retreiving feed

 * 1) Installed the extenasion successfully
 * 2) when i try to subscribe to the feed i get the following link in my browser?

XML Parsing Error: not well-formed Location: http://caddcentre.org/caddwiki/index.php?title=Feeddata&action=feed&feed=atom Line Number 2, Column 1:﻿ <?xml version="1.0" encoding="utf-8"?> ^

Abhi kalyan 12:09, 30 November 2007 (UTC)


 * Hello Abhi kalyan, Please see the previous messages about leading and trailing whitespace. Usually this is a result of some other extension which has extra newlines before the beginning of a PHP file, or at the end of it.  Good luck! -- Jimbojw 00:21, 11 December 2007 (UTC)
