I'm trying to determine if the post is shown in excerpt mode (with a <!--more--> tag or the whole of it is being shown at once. I require this for a plug-in which will insert a piece of code only in full-post mode and not in the excerpt mode.
I've added a filter hook to 'the_content', and tried analyzing the contents of the variable, $content searching for the term <!--more-->. But I guess, WordPress parses this tag, even before it reaches the plug-in hook..
What is the best possible way of determining this?
Second question.. is there a filter hook, that'll apply my plug-ins output ONLY to PAGES and NOT POSTS and vice-versa?
