Re: [Wikitech-l] Problem to get an article's content in MW 1.20.2
Hi, thanks for your suggestions, at the end I found it :-) It was a closed data base connection, that prevented Title::newFrom...-methods to get articleId etc. --- the eval part --- $dbReadOnly2 = wfGetDB(DB_SLAVE); # do some stuff $dbReadOnly2->close(); # use another method that needs data base access will fail --- It is because wfGetDB(...); will get the database object as *reference* not as copy (see PHP code of wfGetDB() in file includes/GlobalFunctions.php) and as it is a reference and some other function closes the dabta base connection then there is "silence" ... at least for the db connection Andreas 2013/1/16 Andreas Plank : > 2013/1/16 Krenair : >> You could try RequestContext::getMain() to get the context source object. >> >> Alex Monk >> >> On 16/01/13 16:56, Andreas Plank wrote: > > I tried many functions in various classes: > RequestContext > WikiPage > Title > Article > ... but it is always the same I do not get the raw page content.

You could try RequestContext::getMain() to get the context source object.

Re: [Wikitech-l] Problem to get an article's content in MW 1.20.2
Hi,
One of Tyler Romeo's suggested approach is to use
Article::newFromTitle($titleObj)
... but it does need a second argument of type IContextSource. I do
not know how to get it or how to instantiate it yet. At the moment it
does not retrieve the page content as well because of the missing
IContextSource ...
Can somebody Maybe Article::newFromTitle($titleObj,
IContextSource-something) would
Do I need that IContextSource? I read at Manual:Article.php to use the
WikiPage class instead, so maybe at this point I don't have to use
IContextSource(?). WikiPage::factory($titleObj) prints the same Title
Object structure as Title::newFromText("Existing page but not existing
for Title object class");
Does it may have to do with data base update, some of the maintenance
scripts? Maybe data in the data base are not entirely correct after
upgrading from MW 1.18 to MW 1.20.2? How do I ensure that the data
base has correct page data? When I run php ./update.php --conf
/path/to/LocalSettings.php all is fine ... any further idea?
Thanks,
Andreas

On the http://offene-naturfuehrer.de/web/Spezial:MobileKeyV1
I want to generate a MobileKey for "Lamium (Deutschland)" (the page
exists) and the PHP code wants to get the content of page "Unterlippe
(Lamiaceae)" (the page exists too) but the PHP code above stops at the
step retrieving the articleID. The strange thing is, when I want to
generate a MobileKey for "Lamium (Deutschland)" and just print out
(1) Title::newFromText("Unterlippe (Lamiaceae)") and
(2) Title::newFromText("Lamium (Deutschland)")
... I get only an articleID for (2) not for (1)
WikiPage::factory ($titleObj) prints the same articleID data as
Title::newFromText(...)

It should be working, and it works for me on 1.20.2
Can you provide more details on that $title->getArticleID(); which is
not working?

Re: [Wikitech-l] Problem to get an article's content in MW 1.20.2
While it may be true that there are better methods to call for this
purpose, an article's id should be 0 if and only if it does not exist
(or perhaps if its in a fake namespace like special).

Re: [Wikitech-l] Problem to get an article's content in MW 1.20.2
I think the best thing to do would be to just avoid getting the article ID
in the first place. If you have a Title object, you can just pass that
object directly to either Article::newFromTitle or to WikiPage::factory.

Hi Andreas
Try this
$someobj = WikiPage::newFromId( $ID );
if(is_object( $someobj ) ){
$text = $someobj->getRawText(); or you can use $text =
$someobj->getText();
}
else{
return true;
}

[Wikitech-l] Problem to get an article's content in MW 1.20.2
Hi,
I'm using MW 1.20.2 and I want to get the content of a page for
further parsing in a PHP application. The PHP application is triggered
via a special page (Special:MobileKeyV1) and parses nature guides for
mobile devices.
I tried to get the content via getArticleID() ...
$titleObj=Title::newFromText("Existing page");
$articleID=$titleObj->getArticleID();
Article::newFromID($articleID)->fetchContent();
etc.
... but it returns $articleID=0 although the page exits. With MW 1.18
this approach worked fine, but after upgrade to MW 1.20.2 it does not
any more.
How do I get the page content correctly?
Article::newFromID($titleObj->getArticleID())->fetchContent(); does
not work because getArticleID() returns 0 or -1 although the page
exits
Or can sombody post a hint, what I'm doing wrong? Is there any context
class needed?
Or where there some big changes (MW 1.18 → 1.20) that are not
described yet on http://www.mediawiki.org/wiki/Manual:Title.php ?
I did also a
sudo php ./maintenance/rebuildall.php --conf ./LocalSettings.php
But it did not help either
Thanks for your help!
Kind regards
Andreas
