[wp-hackers] Best way to verify if a post_id is valid

[Hikari]

tnx for the reply


what I want is basically know if that ID refers to a post that exists and can be accesses

it will be used to get the post permalink and title, and if it's an invalid ID the function should return an error


by "invalid" I mean, beyond an ID that is not in database, also "posts" that are revisions, or weren't published yet (draft, trash, 
etc)

if that ID has a post that can be accesses by a URL, I want its pernalink, else I wanna return an error



get_post() is what I'm doing now, more precisely get_post($value, ARRAY_A), so I'm in the right way

thanks to Google I found http://codex.wordpress.org/Post_Status_Transitions, but I wasn't able to find the difference from draft to 
pending to new status

| Maybe something like:
|
| if ( $post = get_post($post_id) && 'post' == $post->post_type && 'publish'
| == $post->post_status) {
|    // do stuff
| }
|
| Of course, it depends on what you're doing. So, there's no universal "best
| way".
