Howdy @silvermarc,
Great question.
The way to change what Posts in Page is putting out to the page is to modify the posts_loop_template.php file (hopefully after copying into your theme).
Check out the top three pinned posts on the support forum to get a better idea of the mechanics.
In short, you’ll:
- copy posts_loop_template.php into your theme’s root folder
- open the copied file and edit to add the date
The WordPress function that you can add to posts_loop_template.php to add the date is using the function you mention:
<?php echo get_the_date(); ?>
In fact, you may wish to surround it with some markup to make styling easier, so you might use:
<span class="entry-date"><?php echo get_the_date(); ?></span>
I guess the next question is where you want to put it and that’s really up to you. Here’s some example code you can copy/paste into your customized posts_loop_template.php which contains the date.
<!-- Start of Post Wrap -->
<div class="post hentry ivycat-post">
<!-- This is the output of the post title -->
<h2 class="entry-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<!-- This is the output of the excerpt -->
<div class="entry-summary">
<?php the_excerpt(); ?>
</div>
<!-- This is the output of the meta information -->
<div class="entry-utility">
<span class="entry-date"><?php echo get_the_date(); ?></span>
<?php if ( count( get_the_category() ) ) : ?>
<span class="cat-links">
<?php printf( __( '<span class="%1$s">Posted in</span> %2$s', 'twentyten' ), 'entry-utility-prep entry-utility-prep-cat-links', get_the_category_list( ', ' ) ); ?>
</span>
<span class="meta-sep">|</span>
<?php endif; ?>
<?php
$tags_list = get_the_tag_list( '', ', ' );
if ( $tags_list ):
?>
<span class="tag-links">
<?php printf( __( '<span class="%1$s">Tagged</span> %2$s', 'twentyten' ), 'entry-utility-prep entry-utility-prep-tag-links', $tags_list ); ?>
</span>
<span class="meta-sep">|</span>
<?php endif; ?>
<span class="comments-link"><?php comments_popup_link( __( 'Leave a comment', 'twentyten' ), __( '1 Comment', 'twentyten' ), __( '% Comments', 'twentyten' ) ); ?></span>
<?php edit_post_link( __( 'Edit', 'twentyten' ), '<span class="meta-sep">|</span> <span class="edit-link">', '</span>' ); ?>
</div>
</div>
<!-- // End of Post Wrap -->
I hope that helps!
