I was reading this post: When should you use WP_Query vs query_posts() vs get_posts()?, which seems to have become the go-to post for understanding the difference between the different functions for making custom loops.
In the article, it says that
[get_posts] doesn't modify global variables and is safe to use anywhere
Nonetheless, when I inserted into within another loop (I wanted to have a home page showing 3 columns, 2 done with custom fields, one with latest blog posts), I had to preserve the original $post, like so:
<?php global $post; // required $tmp_post = $post; // save original post args = array('numberposts' => 2); // Retrieve just 2 posts $custom_posts = get_posts($args); foreach($custom_posts as $post) : setup_postdata($post); ?> //My posts code here (removed to simplify) <?php endforeach; $post = $tmp_post; //go back to original post ?>
Before I saved the original post, my third column, with the custom field, was blank, but after resetting, as above, it works fine.
Did I misunderstand what that line in the post meant? Did I do something I wasn't supposed to?
