Remove duplication posts everywhere

Hi,

I’d like to not show duplicated posts on a same page for exemple if they are in a widget, big slide and so on I don’t want to see them appearing in the latest article, sidebar…

It will be good if you can implement that by default or through a global checkbox.

Please can you point me out where are all the files I should modify:

For the moment I found the class td_data_source and I did something like that

class td_data_source { 
function sow_exclude_duplicate() {
        global $wp_query;

        $EXCLUDE = $wp_query->posts;

        if (isset($EXCLUDE)) {
            $EXCLUDE_ID = array();

            foreach ($EXCLUDE as $post) {
                $EXCLUDE_ID[] = $post->ID;
            }

            return $EXCLUDE_ID;
        }
    }
}

   if (!empty($this->sow_exclude_duplicate())) {
            $args['post__not_in'] = $this->sow_exclude_duplicate();
        }

Please let me know,

Regards,

Fabien

Hi Radu,

Yes this works as I’m using it of all our websites, $args[‘post__not_in’] is one of the parameter for post and pages to http://codex.wordpress.org/Class_Reference/WP_Query

Basically I normally have one main function I use througout our sites where I pass all the parameter I need, in this case I get all the post id in a global variable from wquery then when another call is done for another component I exclude those Ids

The thing is with your theme I don’t know where all the things are and as I saw quickly you are not using a same function to fetch stuff with WPQuery.

This kind of might help you :

function sowGetPosts($options = array()) {
    $args = array();
    
    foreach ($options as $key => $value)
    {
            $key = strtoupper($key);
            $$key = $value;
    }

    if (!empty($EXCLUDE)) {
        $EXCLUDE_ID = array();

         foreach ($EXCLUDE as $post) {
             $EXCLUDE_ID[] = $post->ID;
         }

         $args['post__not_in'] = $EXCLUDE_ID;
    }
    
    if (isset($FROMCATEGORY)) {
        $cat = get_the_category();

        if (!empty($cat)) {
            $args['cat'] = $cat[0]->cat_ID;    
        }
    }
        
    $args['showposts'] = isset($LIMIT) ? $LIMIT : 5;
    
    $custom_query = new WP_Query($args);

    ...... and so on
    // If no articles get me the last 10
    if(!$custom_query->post_count) {
        sowGetPosts(array('EXCLUDE' => isset($posts) ? $posts : '',
                          'TITLE' => 'Latest Articles',
                          'LIMIT' => 10));
    }
   
    unset($custom_query);
    wp_reset_query();
}

Then I can use it eveywhere

sowGetPosts(array('FROMCATEGORY' => true,
                  'EXCLUDE' => $wp_query->posts,
                  ... and so on
            ));

Please include this in the Theme core.

Hello,

did you have implemented this code in last version 2.1.1?

It’s really useful and resolve the problem of duplicate post. I read your answer on ThemeForest comment, regard to resolve the problem when a post is featured, but between a specific category and recent/popular posts?

I don’t see other solutions.

Please, tell use if we can use this solution for the actual version of theme, and how insert it.

Thanks!
