Template Tags/get posts
Access all post data
Some post-related data is not available to get_posts by default, such as post content through the_content(), or the numeric ID. This is resolved by calling an internal function setup_postdata(), with the $post array as its argument:
<?php $args = array( 'numberposts' => 3 ); $lastposts = get_posts( $args ); foreach($lastposts as $post) : setup_postdata($post); ?> <h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2> <?php the_content(); ?> <?php endforeach; ?>
To access a post's ID or content without calling setup_postdata(), or in fact any post-specific data (data retained in the posts table), you can use $post->COLUMN, where COLUMN is the table column name for the data. So $post->ID holds the ID, $post->post_content the content, and so on. To display or print this data on your page use the PHP echo command, like so:
<?php echo $post->ID; ?>
