Dernier message commandé par date de publication en utilisant WP_Query sur la première page

Je rassemble quelques sites Weben un seulet j'ai créé des articles appropriéset changé leurpost_date (date depublication) à l'heure depublication d'origine. Cependant (même sije listeplus d'un article) le résultat,j'obtiens,est le dernier article selon 'post_modified' assez récent (dernièremise àjour de l'article).

//EDIT - uneexplicationplus détaillée duproblème

Mon article original sur l'ancien site Web date,disons,du 1erjanvier 2001 (date d'origine). Ensuite,je crée unepublication sur lenouveau site Web le 22 septembre 2013 (aujourd'hui)et je règlemanuellement la date depublication dans la zone demodification depublication à la date d'origine. Jepeux voir dans le $ wpdb post_date=2001-01-01et post_modified=2013-09-22. Le dernier shortcode deposte renvoie lepost avec la dernière date post-modified au lieu de la dernière post_date.

//MODIFIER -fin

J'exécute une WP_Querypersonnalisée dans la diapositive d'unplugin,en utilisant une courtebalisepour laplacer là. Leproblèmeest qu'ilprend le derniermessagemodifié au lieu du derniermessagepublié.

Mon codepour le shorttag:

 //[latestpost]
function latestpost_func( $atts ){
    global $post;
    $paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
    $query = new WP_Query( array( 'paged' => $paged ) );
    $latestpost_arg = array(
                          'post_type' => 'post',
                          'posts_per_page' => 1,
                          'orderby' => 'date',
                          'order' => 'DESC',
                          'paged' => $paged,
                          'ignore_sticky_posts' => 1,
                          'category__in' => array( 127, 253 )
            );
    $latestpost_query = null;
    wp_reset_query();
    $latestpost_query = new WP_Query($latestpost_arg);


     if ( $latestpost_query -> have_posts() ) :
      while ($latestpost_query -> have_posts()) :
            $latestpost_query -> the_post();
            if (has_post_thumbnail()) {
                $large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
                $latestpost_image_div = '<div class="slide-post-image"><img src="' . $large_image_url[0] . '" /></div>';
            }

            $latestpost_details_div = '<div class="slide-post-details-div"><h2 class="latest-post-title">' . get_the_title() . '</h2><p class="latest-post-excerpt">' . get_the_excerpt() . '</p></div>';

            $latestpost_output = $latestpost_image_div . $latestpost_details_div;
      endwhile;
     else :
        $latestpost_output = 'Sorry, no posts matched your criteria.';
     endif;

  return $latestpost_output;
 }

 add_shortcode( 'latestpost', 'latestpost_func' );
 

I'm joining together few websites into one and I created appropriate posts and changed their post_date (publish date) to the original time of post. However (even if I list more than 1 post) the result, I get, is the last post according to quite recent 'post_modified' (last update of the post).

// EDIT - more detailed explanation of the problem

My original post on the old website is from, let say, Jan 1 2001 (original date). Next, I create a post on the new website on Sep 22 2013 (today) and manually set the publish date in the Post Edit area to the original date. I can see in the $wpdb post_date=2001-01-01 and post_modified=2013-09-22. The last post shortcode return the post with the latest post-modified date instead of the latest post_date.

// EDIT - end

I'm running a custom WP_Query within a plugin's slide, using a short tag to place it there. The problem is, that it takes the last modified post instead of last published post.

My code for the shorttag:

//[latestpost]
function latestpost_func( $atts ){
    global $post;
    $paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
    $query = new WP_Query( array( 'paged' => $paged ) );
    $latestpost_arg = array(
                          'post_type' => 'post',
                          'posts_per_page' => 1,
                          'orderby' => 'date',
                          'order' => 'DESC',
                          'paged' => $paged,
                          'ignore_sticky_posts' => 1,
                          'category__in' => array( 127, 253 )
            );
    $latestpost_query = null;
    wp_reset_query();
    $latestpost_query = new WP_Query($latestpost_arg);


     if ( $latestpost_query -> have_posts() ) :
      while ($latestpost_query -> have_posts()) :
            $latestpost_query -> the_post();
            if (has_post_thumbnail()) {
                $large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id($post->ID), 'full');
                $latestpost_image_div = '<div class="slide-post-image"><img src="' . $large_image_url[0] . '" /></div>';
            }

            $latestpost_details_div = '<div class="slide-post-details-div"><h2 class="latest-post-title">' . get_the_title() . '</h2><p class="latest-post-excerpt">' . get_the_excerpt() . '</p></div>';

            $latestpost_output = $latestpost_image_div . $latestpost_details_div;
      endwhile;
     else :
        $latestpost_output = 'Sorry, no posts matched your criteria.';
     endif;

  return $latestpost_output;
 }

 add_shortcode( 'latestpost', 'latestpost_func' );
