我编写了以下函数，问题是当我在快捷代码中设置类别时，它会忽略它并显示自定义帖子类型中的所有帖子。所以这只是一种效果。

function resources_query( $atts ) {
    extract(shortcode_atts(array(
        \'category\'      => \'\',
        \'per_page\'  => -1,
        \'orderby\' => \'date\',
        \'order\' => \'ASC\'
    ), $atts));

    $tax_query = array(
        \'taxonomy\' => \'resources_categories\',
        \'field\'    => \'slug\',
        \'terms\'    => array( esc_attr($category) ),
        \'operator\' => \'IN\',
    );
    $args = array(
        \'post_type\'     => \'resources\',
        \'post_status\'       => \'publish\',
        \'posts_per_page\' => $per_page,
        \'orderby\' => $orderby,
        \'order\' => $order,
        \'tax_query\'   => $tax_query
    );
    $resources_query = new WP_Query( $args );
    if ( $resources_query->have_posts() ) :
        $html_out = \'<div class="fg-row row flex-row">\';
        while ( $resources_query->have_posts() ) :
            $resources_query->the_post();
            $title = get_the_title();
            $content = get_the_excerpt();
            $pdf = get_field( "download_pdf" );

            // Do stuff with each post here
            $html_out .= \'<div class="fg-col col-xs-12 col-md-4 fg-text-dark"><section class="icon-box-v3 light-box text-left fg-text-dark"><i class="icon-box-v3-icons ff-font-et-line icon-document fg-text-dark ffb-icon-1"></i>\';

            if( $pdf ):

            endif;

            $html_out .= \'</section></div>\';
        endwhile;
        $html_out .= \'</div>\';

    else : // No results
        $html_out = "No Resources Found.";
    endif;
    wp_reset_query();
    return $html_out;
}

add_shortcode( \'show_resources\', \'resources_query\' );

下面是我的短代码的实际外观[show_resources category="post-surgery-information" per_page="-1"]. 我不知道为什么它会忽略它并显示所有帖子。我查看了其他Stack文章来帮助我进行设置。

$tax_query = array(
    \'taxonomy\' => \'resources_categories\',
    \'field\'    => \'slug\',
    \'terms\'    => array( $category ), // <--------
    \'operator\' => \'IN\',
);
$args = array(
    \'post_type\'     => \'resources\',
    \'post_status\'       => \'publish\',
    \'posts_per_page\' => $per_page,
    \'orderby\' => $orderby,
    \'order\' => $order,
    \'tax_query\'   => array($tax_query) // <--------
);

$tax_query = array(
    array(
        \'taxonomy\' => \'resources_categories\',
        \'field\'    => \'slug\',
        \'terms\'    => array( esc_attr($category) ),
        \'operator\' => \'IN\'
    )
);
