Php wordpress按slug获取类别，如果为true，则添加类

下午好，问题出在这里： 我有一个asside菜单，这个菜单有4个类别，每个类别都有很多子类别，我想做的是，当我在一个子类别的页面上时，我给左边菜单上的a

一个类，一个活动的类，这样我所在的子类别的类别就会保持打开状态。 整个代码如下：

)))

解决方案：

$thisCat = get_category( get_query_var( 'cat' ) );


            <ul class="main-categ">
            <?php foreach ( $categories as $kCat => $vCat ): ?>
                <li class="main-item <?php echo $thisCat->category_parent == $vCat->cat_ID ? 'active' : ''; ?>"><?php
                                $subCategories = get_categories( array(
                                    'orderby' => 'name',
                                    'order'   => 'ASC',
                                    'parent' => $vCat->cat_ID,
                                    'hide_empty' => 0
                                ));?>

                <a class="main-link" href="#<?php echo $vCat->slug; ?>" data-cat="<?php echo $vCat->slug; ?>"><?php echo $vCat->name; ?></a>
                <?php if( $subCategories ): ?>
                <ul class="subcateg">
                    <?php foreach ( $subCategories as $kSub => $vSub ): ?>
                    <li class="<?php echo get_query_var( 'cat' ) == $vSub->cat_ID ? 'activ':'';?>"><a href="<?php echo esc_url( get_category_link( $vSub->cat_ID ) ); ?>"><i class="fa fa-angle-double-right"></i> <?php echo $vSub->name; ?></a></li>
                    <?php endforeach; ?>
                </ul>
                <?php endif; ?>
            </li>
            <?php endforeach; ?>
        </ul>

$thisCat=get_category（get_query_var（'cat'）；

您可以为添加活动类添加以下代码

<?php 
$getcategory = get_category( get_query_var( 'youtcategory_name' ) ); ?>

<ul class="main-categ">
<?php foreach ( $categories as $kCat => $vCat ): ?>
    <li class="main-item <?php echo $getcategory->category_parent == $vCat->cat_ID ? 'active' : ''; ?>"><?php
                    $subCategories = get_categories( array(
                        'orderby' => 'name',
                        'order'   => 'ASC',
                        'parent' => $vCat->cat_ID,
                        'hide_empty' => 0
                    ));?>

    <a class="main-link" href="#<?php echo $vCat->slug; ?>" data-cat="<?php echo $vCat->slug; ?>"><?php echo $vCat->name; ?></a>
    <?php if( $subCategories ): ?>
    <ul class="subcateg">
        <?php foreach ( $subCategories as $kSub => $vSub ): ?>
        <li class="<?php echo get_query_var( 'youtcategory_name' ) == $vSub->cat_ID ? 'activ':'';?>"><a href="<?php echo esc_url( get_category_link( $vSub->cat_ID ) ); ?>"><i class="fa fa-angle-double-right"></i> <?php echo $vSub->name; ?></a></li>
        <?php endforeach; ?>
    </ul>
    <?php endif; ?>
</li>
<?php endforeach; ?>
</ul>



艾哈迈德：我已经找到了一个解决办法，下面我只是无法将它标记为已解决，谢谢。也许你能帮我做这个？这基本上是同一个问题，我只需要做同样的事情，但张贴页面
$thisCat = get_category( get_query_var( 'cat' ) );


            <ul class="main-categ">
            <?php foreach ( $categories as $kCat => $vCat ): ?>
                <li class="main-item <?php echo $thisCat->category_parent == $vCat->cat_ID ? 'active' : ''; ?>"><?php
                                $subCategories = get_categories( array(
                                    'orderby' => 'name',
                                    'order'   => 'ASC',
                                    'parent' => $vCat->cat_ID,
                                    'hide_empty' => 0
                                ));?>

                <a class="main-link" href="#<?php echo $vCat->slug; ?>" data-cat="<?php echo $vCat->slug; ?>"><?php echo $vCat->name; ?></a>

            </li>
            <?php endforeach; ?>

<?php 
$getcategory = get_category( get_query_var( 'youtcategory_name' ) ); ?>
