WP_Query returns post multiple times

    Hi,

    I googled for that problem and already used the search function, but I couldn’t find anyone with the same problem.

    On my index.php i’m using two loops.

    First:

    <?php
				$not_again = array();
				$args = array( 'numberposts' => 4, 'meta_key' => 'ratings_average', 'orderby' => 'meta_value_num', 'order' => 'DESC','category_name' => 'showcase', );
				$postslist = get_posts( $args );
				foreach ( $postslist as $post ) :
				setup_postdata( $post );
				$not_again[]= $post->ID;
			?>

    Second:

    <?php
		$args = array('posts_per_page' => -1, 'post__not_in' => $not_again, 'post_type' => 'post', 'orderby' => 'date',
					'order'   => 'DESC','category_name' => 'showcase');
		$my_query = new WP_Query($args);
		if ($my_query->have_posts()) : while ($my_query->have_posts()) : $my_query->the_post(); ?>

    I’m saving the posts shown in the first loop IDs in the $not_again Array. Then i’m using that array with the post__not_in Option.

    My problem: (example)
    Loop 1 returns: 1 2 3 4
    Loop 2 without category_name returns: 5 6 7 8
    Loop 2 with category_name returns: 5 6 7 8 5 6 7 8

    Anyone ever expierenced that? Any ideas how to solve it?

    Thank you in advance!

  • Hi Taker93

    As rule of thumb after every custom query, we need to use “wp_reset_postdata();” in order to reset to default otherwise there is every possibility of false output.

    So, try and see if that solves your issue.

    Hope this might help you

    Cheers ??

    Hi Tejas,

    thank you for the reply.

    I’m already using

    <?php
			endforeach;
			wp_reset_postdata();
		?>

    at the end of the first loop.

    I don’t know if i can use it at the end of the second because the theme uses Masonry.js . (somekind of infinite scroll stuff)

    Try using that even after second loop.. No harm in trying!

    Well…the posts are somekind of unique now. BUT: Now I see the navigation buttons, which should not be displayed…

    Thank you so far.

    Edit:
    Result without categories is still: Posts are not unique.

    Edit 2:
    I tried:

    <?php $not_again = array();
				$args = array( 'numberposts' => 4, 'meta_key' => 'ratings_average', 'orderby' => 'meta_value_num', 'order' => 'DESC','category_name' => 'showcase', );
				$postslist = get_posts( $args );
				foreach ( $postslist as $post ) :
				$not_again[] = $post->ID;
				setup_postdata( $post );
			?>

    …

    <?php
			endforeach;
			wp_reset_postdata();
		?>
    <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
			<?php if ( in_array(get_the_ID(), $not_again) ) continue; ?>

    …

    <?php endwhile;
		else :
			echo prpin_get_no_result();
		endif;
		wp_reset_postdata();
 		?>

    Result is: Posts are unique. But “previous”-Button is being shown.

    Found out, that the problem was caused by wrong pagination. I disabled the inifinite-scroll script and changed the way of querying.

    These posts were very helpful:

    [resolved] infinitescroll and wp_query is repeating posts
