how to detect when a new post is made?

thanks whooami!

this was a great help.

just a quick question.

I have a function that gets passed the post_id. So I want to get 2 things, the content and the category.

I use:

$usepostid = get_post($post_ID);
         $sendcontent = $usepostid->post_content;

to get the content – but i saw that post_category doesn’t work anymore. It says to use get_post_category() – but only within the loop. How can I get the post category ID outside the loop ?

Thanks!

i tried get_the_category() and it worked fine, even outside the Loop
