    Hi there,

    I need to display two posts from a query but excluding the current category.

    <?php

  // The Query
  $cat_ID = get_the_category($post->ID);
  $post_cat = $cat_ID[0]->cat_ID;

  $args = array(
	'posts_per_page' => 2 ,
	'orderby' => 'rand'
  );

  $the_query = new WP_Query( $args );

  // The Loop
  if ( $the_query->have_posts() ) {
	echo '<ul>';
	while ( $the_query->have_posts() ) {
		$the_query->the_post();
		if ( ! in_category( $post_cat ) ) {
		  echo get_the_excerpt();
		  } else {
                    //HERE IS THE ISSUE
                  }
		}
	echo '</ul>';
  } else {
  // no posts found
  }
  wp_reset_postdata();
?>

    Right now, it stops when it gets to a post within that current category becausse it just gets blank.

    So can I have the two posts to display ?

    Thanks a lot for any help 🙂

    I tried to use that to exclude the category from the source :

    $args = array(
	'cat' => -$post_cat ,
	'posts_per_page' => 2 ,
	'orderby' => 'rand'
);

    Unfortunately, it breaks somehow the split of languages based on Polylang and I get a mix of content.

    That’s why I’m tried the ! in_category way upper.

    The problem with your first code is that you only fetch two posts. Assuming that at least one of them is in current category there’s no way to display two posts… If both are from current category then by using if… in_category() you simply exclude all fetched posts!

    In theory your second code is much better and I’d say it’s at least compliant with WordPress Codex. I’m not sure what mess can Polylang cause but I’d definitely go this way…

    Good luck and if I’ll manage to find something about problems with Polylang and custom queries I’ll let you know.

    Thanks Adam for your feedback !

    Yeah, but all my tries with the second code (‘cat’ => -$post_cat) killed Polylang someway… I’m pushing the first option on my side.

    Thanks again for helping 🙂

    It’s just a “semi-blind shot” (I don’t have Polylang installed anywhere at the moment) but perhaps you try something like this?

    $mylang = get_query_var( 'lang' );
    $args = array(
    ‘cat’ => -$post_cat ,
    ‘posts_per_page’ => 2 ,
    ‘lang’ => $mylang,
    ‘orderby’ => ‘rand’
    );`
    `

    Hum nope, it did not work… =(

    I made some tries to get the current langage from another way, but same result.

    All right, I guess I’ll install polylang on my test WP and give it a try 🙂

    Very nice from you 🙂

    For information, I also tried to add manually the category IDs and it still breaks Polylang posts split

    $args = array(
		'cat' => -78,-79 ,
		'posts_per_page' => 2 ,
		'orderby' => 'rand'
	);

    I keep looking from your $mylang idea, and I got that :

    $language = get_locale(); if ($language == 'fr_FR') { $mylang =  fr ; } else { $mylang = en ;}

    $args = array(
        'cat' => -78,-79 ,
        'lang' => $mylang,
        'posts_per_page' => 2 ,
        'orderby' => 'rand'
    );
    $the_query = new WP_Query( $args );

    It avoids the mix of languages, which is cool.

    But for some reasons, it still doesn’t care about the ‘cat’ => -78,-79 , even here when I write directly the categories ids…

    'cat' => '-78,-79' ,

    Now it seems to work just fine 🙂
