I have block view that should be rendered in the node details page. i.e
/node/*. The block should render latest 6 nodes published under the Category
category_field that the node has its value.
However, the URL is rewritten and the category id
tid is not available. The URL is looks like the following:
So the contextual filter is not available in the URL. So, I created the following PHP code, shown in the screen shot, to get the category tid and return it:
node.tpl.php when I try to
var_dump($node->field_category['und']['tid']); it returns the number of
tid of the current node. However, the above demonstrated code seems to be not work in the PHP filter code. When I try to return any available value for an category id such as
19 for example, it works.
In other words, how could I return the current node's category field id to the filter?
