Oh damn, here is the good syntax:
`
if (!is_post_type(‘forum’) && !is_post_type(‘post’) && !is_post_type(‘topic’) && !is_post_type(‘reply’)){
if (function_exists(‘my_breadcrumb’)) my_breadcrumb();
}
`
Now it works, I just have to find the “else” part with the bbPress breadcrumb to display in the theme and my problem will be resolved.
[sorry for the multi-posts, but I can’t edit my last reply]
OK, I succeeded in doing the first thing.
I checked in the database and found the custom post types in the wp_posts table:
`
if (!is_post_type(‘forum’) || !is_post_type(‘post’) || !is_post_type(‘topic’) || !is_post_type(‘reply’)){
if (function_exists(‘my_breadcrumb’)) my_breadcrumb();
}
`
The problem now is that I have to do it for all the children pages of these custom post types (forum, post, topic and reply), but I can’t find how to do it. I will try something with the get_page_children() function but I am not sure that it will work with custom posts…
