WP Query

  • Hi,

    Having trouble with wp_query ‘category__and’. Cant get it to work.
    This is my code:

    $args = array( 'post_type' => 'product', 'posts_per_page' => 10, 'category__and' => array( 20, 61, 74, 28 ), 'orderby' => 'date' );
$loop = new WP_Query( $args );

while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>
      // Info comes here.
<?php endwhile; ?>
<?php wp_reset_query(); ?>

    Any idea what i’m doing wrong?
    Tanks.

    It doesnt return any posts? Do you have posts that have all the categories assigned to it?

    I have a post that is assigned to all categories. I have tried it with one or two categories but it gave no result.

    What can i get the posts without an error?
    The query works when i remove:’category__and’ => array( 20, 61, 74, 28 ), but i need to get the posts that ar assigned to different categories. It’s an online shop with a search module… You can select a color, a size, …

    But this is my own post?

    I think she meant sharky1989.

    Does ‘category__in’ work?
    Do you have any other loops in the theme template file.

    Can you post the full code of the template file – See theForum Rules on how to post a large excerpt of code.

    Sorry! My bad! ??

    Maybe the posts are fetched but the shortcode doesn’t work properly. try changing this:

    $loop->post->ID

    to this:

    $post->ID

    That also does not work.
    The code is fine i think becaus when i change the query to: 

    $args = array( 'post_type' => 'product', 'posts_per_page' => 10, 'orderby' => 'date' );

    I left out the ‘categorie_and’ and it works. So i think it is the query that is not wright? But i can’t seem to figure out what is wrong.

    Very strange.
    Can you paste this inside your loop to see if post titles are showing up.

    <?php the_title( '<h3>', '</h3>' ); ?>

    that doesn’t change a thing. I can’t see the titles.

    Print_r from the loop:

    Maybe this will help?

    I’m not sure why this isn’t working if you have a post with all categories assigned. Try it with a tax query:

    $args = array(
	'post_type' => 'product',
	'posts_per_page' => 10,
	'orderby' => 'date',
	'tax_query' => array(
		array(
			'taxonomy' => 'category',
			'field' => 'id',
			'terms' => array( 20, 61, 74, 28 ),
			'operator' => 'AND'
		)
	)
);
$loop = new WP_Query( $args );

    Yes it does. The query doesn’t include your category query by looking at the ‘request’ and no posts were found.

    I think a plugin or theme is filtering the query. What plugin are you using for the product posts?
