Manually set global $post vars with an ID, in order to use template tags

Question

I have a function retrieving ID's of posts by very specific means.

I need to be able to set the global $post in order to use functions like the_content(), which does not allow an ID as a parameter.

How can I achieve this?

Answer 1

When your going through your loop add this:

global $post; 
$post = get_post( $ID, OBJECT );
setup_postdata( $post );

//Do something

wp_reset_postdata();

Answer 2

To work with posts outta loop try using:

get_post(post_id)

to get a post with a specific ID out of the loop,when you do this,the global object $post will hold the post which you'v just selected.Now you can get the content using :

$post->post_content .

check the get_post documentation on Wordpress Codex

Answer 3

You may use a one-liner to reset the global post object.

setup_postdata( $GLOBALS['post'] =& $custom_post_object );

When you finish your template or loop be sure to reset the global post so you won't break other templates further down the stack.

wp_reset_postdata();

Note: PHPCS with WordPress standards will complain about overriding the global post so if you're using the WordPress standards you'll need to disable it for the line like so:

setup_postdata( $GLOBALS['post'] =& $post ); //phpcs:ignore

Answer 4

A solution that works for me is:

1. global $post; before the loop
2. setup_postdata($post); inside the loop
3. wp_reset_postdata(); after the loop

Take into account that the name of the variable must be $post
