现在在2012年的主题是the_post_thumbnail() 获取特征图像并将其呈现在主博客页面和单个页面中。我尝试删除它，但它也删除了博客可能具有的任何其他图像。我只想从列出所有帖子的主博客页面和单个页面中删除特征图像。php。

任何帮助都将不胜感激

 <a href="<?php the_permalink(); ?>"><?php the_post_thumbnail(); ?></a>

function wpse70960_filter_post_thumbnail_html( $html ) { if ( ( is_home() || is_single() ) { return \'\'; } else { return $html; } } add_filter( \'post_thumbnail_html\', \'wpse70960_filter_get_post_thumbnail_html\' );

function wpse70960_filter_post_thumbnail_html( $html ) { global $post; $page_template = get_post_meta( $post->ID, \'_wp_page_template\', true ); if ( ( is_home() || is_single() || \'template-blog.php\' == $page_template ) { return \'\'; } else { return $html; } } add_filter( \'post_thumbnail_html\', \'wpse70960_filter_get_post_thumbnail_html\' );

Functions.php：从博客中排除类别

所以很明显，如何从模板中排除某些类别，但我不想修改4个模板，使它们忽略某个类别。有没有一种方法可以将某个类别从阅读设置的“博客”集中排除？我正在将博客分配到名为“博客”的页面。。。但显然，档案和搜索也需要对这一超出类别的内容视而不见。我宁愿在里面做functions.php
