Meta and OG description improvement was created by Ruud van Lent
Hi,
first post here :)
I developed a Joomla! plugin that automatically adds Social Sharing buttons to top / bottom of articles. In last version I have added support for K2.
What the plugin does is add a script to the specified position of the article (or Item when in K2).
the script looks like this:
this works (almost) perfect.
Where this goes wrong is when the article has no meta description and K2 generates one from the intro- or full-text.
K2 uses the following code for this in file ./component/com_k2/views/item/view.html.php
The 'cullprit' is in the strip_tags function.
This strips the tags from the description but does not strip the code itself!
so <script type="javascript/text>herecomesthejquerycode</script> becomes herecomesthejquerycode
When posting that page on Facebook (and G+) the text that is being posted starts with "herecomesthejquerycode'... which is wrong :(
I have solved this with a simple regex. The new code in view.html.php will look like (line 2 is added):
What this code (second preg_replace) does is strip the <script...> and </script> tags AND everything (the script itself) in between :)
Hope this helps!
regards,
Ruud.
