The plugin is meant to display either text or an image, both in popup form, when you hover over certain words that you identify. For my site what I do is enter in stock tickers into the plugins database and link them each to their own dynamic chart image which I get from my charting program. So in the example I linked to you, EDIG was the stock ticker. Anytime someone hovered over the letters EDIG in my forum, it would display the image I had linked it to, which was the dynamic chart image (which updates upon refresh).
So after trying to research this and experiment, I stumbled upon filters. I see that the SP forum is displayed in the_content filter. I went through the php file for the plugin and found where they ran the add_filter and specified the_content, but I was trying to figure out where the topic titles output to. You answered that question just now so I added the same line with the sph_TopicIndexName filter, and it almost worked!
Now when I go look at the topic titles the key words that i’ve specified all indeed have the underline and look like the charts are going to pop up, but the message “Browse the thread…” still shows up instead. Adding that filter definitely worked, I just need to figure out how to disable that message so the chart can popup instead.
I apologize again for confusing the heck out of you, I’m learning as we go along and am slowly starting to put these pieces together. Thanks for your patience and help so far.
