Function Reference/the ID

Description

Displays the numeric ID of the current post. This tag must be within The Loop.

Note: This function displays the ID of the post, to return the ID use get_the_ID().

Usage

 <?php the_ID(); ?> 

Parameters

This tag has no parameters.

Examples

Default Usage

<p>Post Number: <?php the_ID(); ?></p>

Post Anchor Identifier

Provides a unique anchor identifier to each post:

<h3 id="post-<?php the_ID(); ?>"><?php the_title(); ?></h3>

Note: In XHTML, the id attribute must not start with a digit. Since the_ID returns the post ID as numerical data, you should include at least one alphabetical character before using it in an id attribute, as in the example above.

Since: 0.71
