The get_the_ID() WordPress function
If you need to obtain the post ID from your posts, you can easily use the get_the_ID() WordPress function. In this article, we will introduce you to the get_the_ID() function.
<?php get_the_ID(); ?>
This function does not have any parameters that can be called within it. It simply returns the post ID exactly as it is.
$postid = get_the_ID();
In this example, we use the get_the_ID() function to get the post ID, and assign it to the $postid variable. Then, we display the contents of the $postid variable using the PHP echo command.
For more information on the get_the_ID() function, take a look at the get_the_ID() WordPress Codex page.
