show excerpts on twentytwelve childtheme blog page

Try using

<?php if ( is_search() || is_home() || is_archive() ) : ?>

Right now your saying, if it’s search or archive. The blog isn’t an archive.

I’m not sure if is_home() will work, but it might. I know it would if your homepage is the blog.

Looking at the content.php of 2012 a bit more closely, I can see this on line 33:

<?php if ( is_search() ) : // Only display Excerpts for Search ?>
		<div class="entry-summary">
			<?php the_excerpt(); ?>
		</div><!-- .entry-summary -->
		<?php else : ?>
		<div class="entry-content">
			<?php the_content( __( 'Continue reading <span class="meta-nav">&rarr;</span>', 'twentytwelve' ) ); ?>
			<?php wp_link_pages( array( 'before' => '<div class="page-links">' . __( 'Pages:', 'twentytwelve' ), 'after' => '</div>' ) ); ?>
		</div><!-- .entry-content -->
		<?php endif; ?>

Try getting rid of the if else entirely to just this:

<div class="entry-content">
			<?php the_excerpt(); ?>
		</div><!-- .entry-content -->

Hi Christine. Your first solution worked! Thanks so much! I thought for sure the blog page is an archive.
I have tried your second suggestion before, but that makes everything, even pages, show excerpts.Very strange. My homepage is a static page, not a blog.

Christine

I tried your suggestion of including just

<div class="entry-content">
			<?php the_excerpt(); ?>
		</div><!-- .entry-content -->

But when I click the title to go read the full article, it’s just the excerpt again :-/

Actually, I found the issue. Change a single line:

<?php if ( is_search() ) : // Only display Excerpts for Search ?>

to:

<?php if ( is_search() || is_home() ) : // Only display Excerpts for Search and Index ?>

Now, whatever page you have set your Posts to be on will only show excerpts, but clicking the header links will display the entire post.
