So, what I am trying to do is creating a slideshow plugin that won't require end user to write a single line of code. I can't use custom posts because I need to keep it simple for the end user.
Is there a hook or a filter that would let me include my php generated code right after the
body_class() ?
Is it true that the only hook I can use is
the_content() ?
Thank you.
As every theme is different you can't really expect a plugin to know where to put the slideshow in.
As you say the best place would be the content filter if that's where you want it. If you want it anywhere else you could inject it after using jquery?
The body_class() functions also offers a filter, if that's what you're looking for:
add_filter('body_class', 'my_body_classes');
function my_body_classes( $classes ) {
// Your code here
return $classes;
}
However, if you want to add the content inside the body right after it starts, that would probably not possible. Unless there is a custom function right after the body tag that can be hooked into, there is no easy way to do this.
You can do a full preg_replace() on pages though, but it is most likely costly.
