Single post - display list of all posts + specific post

Question

my single post looks like that: http://pastebin.com/KdEbs82P

I want to display on single post two things:

• list of ALL posts in general
• single post title
• content

What I achieved right now is not satisfing because I AM displaying all posts (and it works ok) but the second part (connected with showing only specific post title and content) don't work. By don't work I mean - it shows only the newest one;/ So giving it into real example:

I have 2 posts called "News about IT" and "TV series". Post about TV is the newest one. After clicking on News about IT i will see all posts in the top and as a main part - title and content of NEWS ABOUT IT. Right now using my solution it shows TV series as a newest post..

how to achieve my solution?

Answer 1

When the single post template is loaded, WordPress has already queried the database for that post. When you call query_posts('post_type=post&posts_per_page=1');, and then run the loop, this simply loads and outputs a single post, which by default will be the latest post. It also has the side-effect of overwriting the original main query.

You don't need to, nor should you ever call query_posts in the template.

To load additional posts beside the single post you are currently viewing, use WP_Query, and leave the main query unaltered.

// load and display all posts
// setting post_type is unnecessary, it will default to post
$all_posts = new WP_Query( array( 'posts_per_page' => -1 ) );
while( $all_posts->have_posts() ):
    $all_posts->the_post();
    // your markup for all posts
endwhile;

// reset the global post variable
wp_reset_postdata();

// now output the single post
// no need for a query, the post data already exists
// in the global $wp_query
while( have_posts() ):
    the_post();
    // your markup for the single post
endwhile;
