我正在使用eList wordpress主题。

现在，主页上显示了列出的所有类别的缩略图。现在，在主题上，您将看到它们在类别下没有子类别，只有列表

现在在我的主题中，我有一些子类别，主题确实为此做了准备。查看我的网站here 以及标题中搜索栏旁边的下拉列表，查看我对子类别的定义

Question:

How do I only list the MAIN categories on the home page, and NOT the sub-categories of the main categories as well?

以下是控制缩略图的主页部分的代码：

<?php
    $elist_categories_args = array( \'hide_empty\' => 0 );

    if ( \'on\' == get_option(\'elist_listings_hide_empty\') ) $elist_categories_args[\'hide_empty\'] = 1;

    if ( is_tax() ) {
        $et_term = get_queried_object();
        $elist_categories_args[\'child_of\'] = $et_term->term_id;
    }

    $categories = get_categories( \'taxonomy=listing-category\' );

    $elist_listing_categories = get_terms( \'listing_category\', apply_filters( \'listing_categories_args\', $elist_categories_args ) );
    $elist_category_images = false !== get_option( \'elist_category_images\' ) ? (array) get_option( \'elist_category_images\' ) : array();
    $et_count = 0;

    if ( $elist_listing_categories ){ ?>
        <section id="listing-categories">
            <div class="container clearfix">
                <h1><?php esc_html_e( \'Listing Categories\', \'eList\' ); ?></h1>
                <?php foreach( $elist_listing_categories as $elist_listing_category ) { ?>
                    <?php
                        $et_current_term_query = new WP_Query( 
                            array(
                                \'post_status\' => \'publish\',
                                \'tax_query\' => array(
                                        array(
                                            \'taxonomy\' => \'listing_category\',
                                            \'field\' => \'id\',
                                            \'terms\' => $elist_listing_category->term_id
                                        )
                                    )
                            )
                        );
                    ?>

                    <?php $et_count++; ?>
                    <div class="l-category<?php if ( $et_count % 3 == 0 ) echo \' last\'; ?>">
                        <?php $et_listing_category_link = get_term_link( $elist_listing_category ); ?>
                        <?php if ( isset( $elist_category_images[$elist_listing_category->term_id] ) && \'\' != $elist_category_images[$elist_listing_category->term_id] ) { ?>
                            <div class="thumb">
                                <a href="<?php echo esc_url( $et_listing_category_link ); ?>">
                                    <img class="item-image" alt="<?php echo esc_attr( $elist_listing_category->name ); ?>" src="<?php echo esc_attr( et_new_thumb_resize( et_multisite_thumbnail( $elist_category_images[$elist_listing_category->term_id] ), 70, 70, \'\', true ) ); ?>"/>
                                    <span class="overlay"></span>
                                </a>
                            </div>  <!-- end .thumb -->
                        <?php } ?>
                        <div class="description">
                            <h2><a href="<?php echo esc_url( $et_listing_category_link ); ?>"><?php echo esc_html( $elist_listing_category->name ); ?></a></h2>
                            <p class="info"><?php if ( 1 == $et_current_term_query->found_posts ) printf( __(\'%d Listing\',\'eList\'), $et_current_term_query->found_posts ); else printf( __(\'%d Listings\'), $et_current_term_query->found_posts ); ?></p>
                            <?php if ( \'\' != $elist_listing_category->description ) { ?>
                                <p><?php echo esc_html( $elist_listing_category->description ); ?></p>
                            <?php } ?>
                        </div> <!-- end .description -->    
                    </div> <!-- end .l-category -->
                <?php } ?>
            </div> <!-- end .container -->
        </section> <!-- end #listing-categories -->
<?php } ?>

要精确指出以上代码，以下是保存动态填充缩略图的html部分：

<div class="l-category<?php if ( $et_count % 3 == 0 ) echo \' last\'; ?>">
                        <?php $et_listing_category_link = get_term_link( $elist_listing_category ); ?>
                        <?php if ( isset( $elist_category_images[$elist_listing_category->term_id] ) && \'\' != $elist_category_images[$elist_listing_category->term_id] ) { ?>
                            <div class="thumb">
                                <a href="<?php echo esc_url( $et_listing_category_link ); ?>">
                                    <img class="item-image" alt="<?php echo esc_attr( $elist_listing_category->name ); ?>" src="<?php echo esc_attr( et_new_thumb_resize( et_multisite_thumbnail( $elist_category_images[$elist_listing_category->term_id] ), 70, 70, \'\', true ) ); ?>"/>
                                    <span class="overlay"></span>
                                </a>
                            </div>  <!-- end .thumb -->
                        <?php } ?>
                        <div class="description">
                            <h2><a href="<?php echo esc_url( $et_listing_category_link ); ?>"><?php echo esc_html( $elist_listing_category->name ); ?></a></h2>
                            <p class="info"><?php if ( 1 == $et_current_term_query->found_posts ) printf( __(\'%d Listing\',\'eList\'), $et_current_term_query->found_posts ); else printf( __(\'%d Listings\'), $et_current_term_query->found_posts ); ?></p>
                            <?php if ( \'\' != $elist_listing_category->description ) { ?>

                            <?php } ?>
                        </div> <!-- end .description -->    
                    </div> <!-- end .l-category -->
