I was building a gift registry system where users could create and customize their own registry pages.<\/p>\n\n\n\n

I needed a way to connect the author ID to the post ID and display a different template based on who was viewing the gift registry page.<\/p>\n\n\n\n

But I needed to do it outside the loop.<\/p>\n\n\n\n

How to get the WordPress author ID from a post ID<\/strong>: The code to get the author ID from a post ID outside the loop is get_post_field( 'post_author', $post_id );<\/em> where $post_id is the ID of the post or page you are looking for.<\/p>\n\n\n\n

Here's the code in a more clear format.<\/p>\n\n\n\n

$post_id = 257;\n$author_id = get_post_field( 'post_author', $post_id );<\/code><\/pre>\n\n\n\n
You'll get back a string with just the ID of the author.<\/p>\n\n\n\n
In this example, I'm assuming you're just after the author for the page with ID 257. In reality, you'll probably get that programmatically, rather than hard coding like this.<\/p>\n\n\n\n
This is the same format for all pages and posts. WordPress treats pages as just a type of post.<\/p>\n\n\n\n
If you're working with a WordPress post object, you don't need to extract the ID first. You can pass the object into the function instead of $post_id<\/em>.<\/p>\n\n\n\n
What you do with the Author ID is up to you, but the next step is often to convert the Author ID into the chosen display name of that Author.<\/p>\n\n\n\n
How to get Author Name from a Post ID<\/h2>\n\n\n\n
To get the author display name from a post ID, use this code:<\/p>\n\n\n\n
$post_id = 257;\r\n$author_id = get_post_field( 'post_author', $post_id );\n$author_name = get_the_author_meta( 'display_name', $author_id );<\/code><\/pre>\n\n\n\n
<\/p>\n\n\n\n
What other information can you get from get_post_field<\/em>?<\/h2>\n\n\n\n
By changing the first parameter of get_post_field<\/em>, ie the 'post_author'<\/em> in the earlier examples, you can extract the information in the table below.<\/p>\n\n\n\n
I ran this on a sample page from a default install. Your information will be different.<\/p>\n\n\n\n
Note that the parameters in the field<\/em> column are case sensitive. So you have to use \"ID\" rather than \"id\".<\/p>\n\n\n\n

As you can see, a number of the columns are empty.<\/p>\n\n\n\n
The post_content<\/em> will pull the full content, complete with line breaks. I just reduced it to make it easy to display in the table.<\/p>\n\n\n\n
Notice that the dates are formatted Year\/Month\/Day. That makes it easy to figure out, rather than the confusion over whether it's using the regular format (day\/month), or the US format (month\/day).<\/p>\n\n\n\n
The post_name<\/em> field is also called the slug or the permalink. The different names it uses in different places can cause some confusion if you've not come across it before.<\/p>\n\n\n\n
The post_password<\/em> field displays in plain text, rather than being encrypted. This is also how it's stored in the database.<\/p>\n","protected":false},"excerpt":{"rendered":"
