Hi,
Instead of the code <?php the_content();?>, just use <?php the_excerpt?>. You can do this either on index.php or home.php
For example; on index.php, you might have the code snippet
<?php if(have_posts()) : ?>
<?php while (have_posts()) : the_post();?>
<h1>
title=<?php the_title();?>>
<?php the_title();?>
</h1>
<?php the_excerpt();?>
<div class=”contentmeta”>
Written by <?php the_author();?>, on <?php the_time(‘n.j.Y’);?>,
filed under <?php the_category(‘, ‘)?> and tagged <?php the_tags(”,’ | ‘,”)?> .
>Continue reading <?php the_title(); ?> →
</div>
<?php endwhile;?>
It will show only the excerpt, and the <?php the_title?> is linked to the full post. Of course on, your single.php, you need to use <?php the_content();?>
