Category Wordpress Problems

Question

I am taking care of a news site in Wordpress and I realized that when it is selected more than one category by matter of the following conflict:

By the URL I am on the page of the category Lifestyle only that it returns the matter of Health/ Beauty. These matters are marked as category :Lifestyle, Health/Beauty. This is the code of the categories page

get_header(); ?>
    <div id="primary" class="content-area">
        <main id="main" class="site-main">
        <div class="container">
            <div class="row">
<?php
        if ( have_posts() ) : ?>

            <header class="page-header">
<?php
$args = array(
    'category_name' => $slug
);
$terms = get_the_terms( get_the_ID(), 'category');
if( !empty($terms) ) :
    $term = array_pop($terms);
    $cor = get_field('cor', $term );
    $slug = $term->slug;
endif;
?>

<h1 style="color:<?php echo $cor; ?>" class="page-title tac"><?php echo $term->name; ?></h1>



            </header><!-- .page-header -->

Answer 1

The problem is here:

$terms = get_the_terms( get_the_ID(), 'category');
    if( !empty($terms) ) :
        $term = array_pop($terms);
        $slug = $term->slug;
    endif;

get_the_terms() brings a list of the categories associated with the post without any special order (I think it comes in the order that were recorded in the bank), there at $term = array_pop($terms) you waive all other terms and get only the last one. Here plays this term on category_name => $slug and redoes the query, there is no way to bring more than one category like this.

Strictly speaking, and from what you can see from the layout, all these calls to $query = new WP_Query are unnecessary. Just calling the page with the right URL you already have the right posts to display. The changes made in this piece:

// The Query
$args = array(
    'post_type' => 'post',
    'post__not_in' => $ids,
    'posts_per_page' => 4,
    'category_name' => $slug,
    'showposts' => 1, 
    'paged'=>$paged
);
$query = new WP_Query( $args );

Could be done once, by the hook pre_get_posts, and the page would be clean, running only the original query.

ps.: a solution terrible, horrible and not recommended to have the posts appear correctly would change:

$term = array_pop($terms);
$slug = $term->slug;

for

$term_ids = wp_list_pluck( $terms, 'term_id' );

and 'category_name' => $slug, for 'category__in' => $term_ids

This will make the posts appear, but you keep making 3 or 4 times more queries to the bank ($$$) than necessary.

Answer 2

I don’t understand what conflict.

In Wordpress, when you select several categories in a post, it puts in the friendly post URL the first category q vc selected.

And the post always appears in the selected categories.

The code has nothing wrong, You’re picking the posts of the selected category, as this post is in the two categories, so, will display in this category also.
