PHP+Genesis Simple Hooks多分类文章重复显示头部问题求助

问题说明 #

使用PHP和Genesis Simple Hooks为不同分类文章分配头部时，单分类文章显示正常，但文章被分配多个分类（如同时属于news和podcast-season-4）时，页面会加载多个头部。需要实现规则：当文章同时包含这两个分类时，不显示news对应的头部。

原代码（导致重复头部） #

STRING ONE #

<?php
$post = $wp_query->post;

if ( in_category ( array ( 'news' , 'featured-news'  )  ) ) {
    echo
'<div class="wrap"><div class="entry-content">
<h1 class="wp-block-heading graya"><a href="https://baker.utk.edu/news-and-events/news-archive/">News</a></h1>
</div></div>
';
}
?>

STRING TWO #

<?php
$post = $wp_query->post;

if ( in_category ( array ( 'podcast-season-4'  ) ) ) {
    echo
'<div class="wrap"><div class="entry-content"><a href="https://baker.utk.edu/news-and-events/podcast/"><div class="wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow">
<figure class="wp-block-image alignleft size-large is-resized podcast-icon" ><img decoding="async" src="https://baker.utk.edu/wp-content/uploads/2024/02/YMBR.Logo_.Smokey.Slant_.svg" alt="You Might Be Right Logo" class="wp-image-8490" style="width:90px;height:auto"></figure></a>

<h1 class="wp-block-heading graya"><a href="https://baker.utk.edu/news-and-events/podcast/">Podcast</a></h1>
</div></div></div>
';
}
?>

修改后的代码方案 #

将两个逻辑整合，优先判断高优先级分类，避免重复输出：

<?php
$post = $wp_query->post;

// 优先处理podcast-season-4分类，满足则输出播客头部
if (in_category('podcast-season-4')) {
    echo '<div class="wrap"><div class="entry-content"><a href="https://baker.utk.edu/news-and-events/podcast/"><div class="wp-block-cover__inner-container is-layout-flow wp-block-cover-is-layout-flow">
<figure class="wp-block-image alignleft size-large is-resized podcast-icon" ><img decoding="async" src="https://baker.utk.edu/wp-content/uploads/2024/02/YMBR.Logo_.Smokey.Slant_.svg" alt="You Might Be Right Logo" class="wp-image-8490" style="width:90px;height:auto"></figure></a>

<h1 class="wp-block-heading graya"><a href="https://baker.utk.edu/news-and-events/podcast/">Podcast</a></h1>
</div></div></div>';
} 
// 仅当文章不属于podcast-season-4时，才判断是否输出news头部
elseif (in_category(array('news', 'featured-news'))) {
    echo '<div class="wrap"><div class="entry-content">
<h1 class="wp-block-heading graya"><a href="https://baker.utk.edu/news-and-events/news-archive/">News</a></h1>
</div></div>';
}
?>

逻辑说明 #

• 用elseif替代独立if，确保同一时间只会触发一个头部输出逻辑
• 给news分类的判断添加排他条件：只有当文章不属于podcast-season-4时，才会输出新闻头部
• 优先处理podcast-season-4分类，保证多分类场景下只显示高优先级的头部
