我有使用types插件创建的自定义帖子类型和类别。

我使用Categories images插件允许/创建类别图像。

我有一个循环，显示中某个类别的帖子<li>s

每个<li> 具有需要获取指定给该类别的图像的背景样式属性。

这是我的适用代码：

$film_categories = get_terms( \'category\' );

    foreach ( $film_categories as $film_category ) {
        $film_category_query = new WP_Query( array(
            \'post_type\' => \'film\',
            \'tax_query\' => array(
                array(
                    \'taxonomy\' => \'category\',
                    \'field\' => \'slug\',
                    \'terms\' => array( $film_category->slug ),
                    \'operator\' => \'IN\'
                )
            )
        ));
        $term_id = get_terms(\'category\');

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

        //$film_background_image = apply_filters( \'taxonomy-images-queried-term-image-url\', \'\' );
        //$film_background_color = types_render_field("film-background-color");
        $hide_all_info         = types_render_field("hide-all-info");
        $film_image            = types_render_field("film-image");
        $film_meta_info        = types_render_field("film-meta");
        ?>

        <?php var_dump($term_id); ?>
            <li id="<?php echo $film_category->{\'slug\'}; ?>" style="background: url(<?php echo z_taxonomy_image_url($term_id); ?>); background-size: cover;">

array(2){
    [0]=> object(stdClass)#380 (9)
        { ["term_id"]=> string(1) "3" ["name"]=> string(10) "Commercial" ["slug"]=> string(10) "commercial" ["term_group"]=> string(1) "0" ["term_taxonomy_id"]=> string(1) "3" ["taxonomy"]=> string(8) "category" ["description"]=> string(0) "" ["parent"]=> string(1) "0" ["count"]=> string(1) "1" }
    [3]=> object(stdClass)#377 (9)
        { ["term_id"]=> string(1) "5" ["name"]=> string(4) "Reel" ["slug"]=> string(4) "reel" ["term_group"]=> string(1) "0" ["term_taxonomy_id"]=> string(1) "5" ["taxonomy"]=> string(8) "category" ["description"]=> string(0) "" ["parent"]=> string(1) "0" ["count"]=> string(1) "1" }
}
