I think this is a Ctools context question. I'm writing my first Panels style plugin and am having trouble getting field values from nodes inside the pane. I'm basically trying to recreate the plugin from this tutorial, http://precessionmedia.com/blog/creating-custom-panels-style-plugin-background-image-support, but I have changed it from a region plugin to pane plugin. The pane contains a list of node fields generated by Views, and I need to get the info from an image field but I'm not sure how to proceed.
In the link above, the render region callback uses this function:
ctools_context_keyword_substitute($string, $keywords, $contexts, $converter_options = array()), where
$vars['display']->context, but this array is empty for me. I'm also not sure what values to use for
$string. In the example link above,
$string is replaced by the value entered into the style plugin settings form and the example given in the tutorial plugin is
%node:field_image, isn't this just a token? I'm not sure if this is the right token to use, but I believe the missing context array is what is breaking this function for me.
Thanks, any help is greatly appreciated.
