have_posts() inaccurate output

    Heya,

    I’m working on a custom theme and the simple PHP function I’m using to determine if a post exists isn’t working. Any idea why this might be?

    <?php if(have_posts()) : ?>
     post found
 <?php else : ?>
     <?php echo wpautop('Sorry, no posts were found'); ?>
 <?php endif; ?>

    The only post is the default “Hello World!”.

    This code displays “post found” whether I’ve deleted the post, or the post is active.

    I don’t get the “Sorry, no posts were found” message after moving the post to the trash. I’ve cleared my cache.

    Appreciate any help

    You need to include whole loop.
    In this article you can find everything you need:
    The Loop

    P.s. you use wpautop in wrong context. If you want to output/echo some strings, you should use localize function like this:

    In addition to using The Loop, have_posts() works in context with the main, global query object. If your code occurs on a single page template for example, the main query is for that page and the status of other posts like Hello World are irrelevant.

    For have_posts() to work for blog posts, the main query has to be for a blog archive.

    For the record, I’m sure this can be far more eloquent but it works…

    $wp_query = new WP_Query( array ( 'posts_per_page' => -1 ) );
 if ( have_posts() ) : while ( have_posts() ) : the_post(); 
    echo "Post exists";
 endwhile; else :
    esc_html_e( 'Sorry, no posts exist.' );
 endif;

    Thanks again –
