Question

我在显示带有Ajax类别的产品时遇到问题。我已经渲染了所有类别和页面上的所有产品，并且我的类别是链接，并且我禁止对链接执行默认操作，而我想实现这一目标。当您单击类别的链接时，该链接会触发ajax并显示该类别的波纹管产品，所有操作均在同一页面上发生，而无需重新加载。但是当我单击类别链接时，我得到的只是“找不到帖子”

function ajax_filter_get_posts( $taxonomy ) {

    // Verify nonce
    if( !isset( $_POST['afp_nonce'] ) || !wp_verify_nonce( $_POST['afp_nonce'], 'afp_nonce' ) )
      die('Permission denied');

    $taxonomy = $_POST['taxonomy'];

    // WP Query
    $args = array(
      'tag' => $taxonomy,
      'post_type' => 'product',
      'posts_per_page' => 10

    );


    if( !$taxonomy ) {
      unset( $args['tag'] );
    }

    $query = new WP_Query( $args );

    if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post();

      $output  = '<h2><a href="'.get_permalink().'">'. get_the_title().'</a></h2>';
      $output .= get_the_excerpt();

      $result = 'success';

    endwhile; else:
      $output = '<h2>No posts found</h2>';
      $result = 'fail';

    endif;

    $response = json_encode($output);
    echo $response;

    die();
  }

  add_action('wp_ajax_filter_posts', 'ajax_filter_get_posts');
  add_action('wp_ajax_nopriv_filter_posts', 'ajax_filter_get_posts');

在您的查询参数中，您使用tag进行过滤，而您传入的分类术语实际上是一个product_cat。

尝试将ajax_filter_get_posts中的查询参数更改为以下内容：

$args = array(
  'post_type' => 'product',
  'posts_per_page' => 10
  'tax_query' => array(
    array (
      'taxonomy' => 'product_cat',
      'field' => 'slug',
      'terms' => $taxonomy,
    )
  ),
);

通过显示产品的AJAX问题按类别过滤产品
