help: Undefined property: stdClass notice question

[Ruud van Lent]

Hi,

A user of one of my plugins just reported the following notice:

Notice: Undefined property: stdClass::$language in C:\web\IWWA\plugins\content\myplugin\myplugin.php on line 140

Notice: Undefined property: stdClass::$fulltext in C:\web\IWWA\plugins\content\myplugin\myplugin.php on line 504

when looking at those lines I have the following code:

140 > $url = JRoute::_(ContentHelperRoute::getArticleRoute($article->slug, $article->catid, $article->language), false, ($uri->isSSL() == '1' ? '1' : '-1'));
504 > preg_match_all('/<img .*src=["|\']([^"|\']+)/i', $article->introtext . $article->fulltext, $matches_image);

It is a content plugin. The error generated is on a Joomla installation with flexicontent.
So it looks like the $article->language and $article->fulltext are causing problems. Could this be because these are 'empty'?

Could this be flexicontent related or is my code missing a check on the existence of these classes?

Hope somebody can share a light :)

You need to check if those attributes exist, because the
onPrepareContent event is called by several different areas of Joomla,
not all of them sending in a full article. So you might just get an
object with a text attribute with the content to modify and nothing else.

Hi Hannes, thanks for looking over my shoulder :)

Can I use this function: bool property_exists ( mixed $class , string $property )
and if false how can I set the value to something that will not raise the notice?

What is a best practise for this: I have looked at other content plugins, but cannot seem to find one that does this check? Am I just unlucky to run into this? Should I check all the properties?

TIA Ruud
