Question

Good night, everybody, all right ?

I am trying to list only the products of the category when I enter the page of the category of such a product, what is happening it lists all my products and I can not only list them.

Follows my code:

<div class="wc-products">                       
    <ul class="products columns-3">
        <?php
            $args = array(  'post_type'        => 'product', 
                            'posts_per_page'   => 15, 
                            'taxonomy'     => 'product-category', //woocommerce
                            'orderby'      => 'name',
                            'empty'        => 0
                        );
            $loop = new WP_Query( $args );
            while ( $loop->have_posts() ) : $loop->the_post();
                global $product;

                $parcela    = get_field("parcela");
                $parcela    = (float)$parcela;
                $parcela    = number_format($parcela, 2, ',', '.');
                $qt_parcela = get_field("qt_parcela");
                $avista     = get_field("a_vista");
                $avista     = (float)$avista;
                $avista     = number_format($avista, 2, ',', '.');
                $price      = get_post_meta( get_the_ID(), '_regular_price', true);
                $formatado  = (float)$price;
                $valor      = number_format($formatado, 2, ',', '.');
                $currency   = get_woocommerce_currency_symbol();

Answer 1

Simply restrict the search by passing the Slug of the current product category. To retrieve Slug, use the get_queried_object() function. This function returns the object of the current page. See below:

The arguments of your query are:

$args = array(  'post_type' => 'product', 
                'posts_per_page'   => 15, 
                'taxonomy'     => 'product-category', //woocommerce
                'orderby'      => 'name',
                'empty'        => 0
       );

You must replace it with this:

    $obj = get_queried_object();
    $cat_slug = $obj->slug;
    $args = array(
        'post_type' => 'product',
        'posts_per_page'   => 15,
        'tax_query' => array(
            array(
                'taxonomy' => 'product_cat', //woocommerce
                'field' => 'slug',
                'terms' => array($cat_slug),
                'operator' => 'IN',
            ),
        ),
        'orderby'      => 'name',
        'empty'        => 0
    );
