I'd like to have even more control of where this code appears on my client's site. Shortcode is great but that would require my client to always put the shortcode in at the beginning of every post.
What is the code I would use to insert this into the single.php file?
In other words, is there something like a "if function exists" kind of code I can copy and paste in place? I have done this with a number of plugins like pixopoint menus etc.
Any help at all would be greatly appreciated!
