I'm trying to use the $pic_row filter in a plugin.

What I did: Add a filter.

$thisplugin->add_filter('thumb_data','do_title');

The corresponding function (shouldn't do anything ATM but return $pic_row in its original state):


function do_title()
{
global $pic_row;
return $pic_row;
}


As far as I understand, the result should be no change. But in fact, the thumbs are gone. Why?

regards
Timo

Should be


function do_title($pic_row)
{
return $pic_row;
}


What you are filtering is the parameter.

Thanks a lot! :)
