我在单曲中使用此代码。php和它的工作非常完美。但在指数中。php未显示任何内容。
仅有一个的php:
<div id="relatedposts">
<?php $orig_post = $post;
global $post;
$categories = get_the_category($post->ID);
if ($categories) {
$category_ids = array();
foreach($categories as $individual_category) $category_ids[] = $individual_category->term_id;
$args=array(
\'category__in\' => $category_ids,
\'post__not_in\' => array($post->ID),
\'posts_per_page\'=> 4, // Number of related posts that will be shown.
\'caller_get_posts\'=>1
);
$my_query = new wp_query( $args );
if( $my_query->have_posts() ) {
while( $my_query->have_posts() ) {
$my_query->the_post();?>
<div class="related">
<a href="<? the_permalink()?>" title="<?php the_title(); ?>">
<?php if(has_post_thumbnail()) {
the_post_thumbnail(array(100,100), array( \'class\' => \'relthumb\' ));
} else {echo \'<img class="relthumb" src="\'.get_bloginfo(\'template_url\').\'/images/noimgrelated.png" />\';
}?></a>
<div class="title"><a href="<? the_permalink()?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></div>
</div><!-- /* .related -->
<?
}
echo \'\';
}
}
$post = $orig_post;
wp_reset_query(); ?>
</div><!-- /* .relatedposts -->
如何在索引中工作?对不起,我的英语。

该代码应该有效。我刚刚在自己的索引中进行了测试。php和它的工作。您确定正在查看索引吗。php文件。有时,WP实际上会提取不同的模板:For more info, see WP template hierarchy diagram. 要测试您看到的模板,请将此代码放在函数中。php文件临时:
add_action(\'wp_head\', \'show_template\');
function show_template() {
global $template;
echo \'<span style="color: #000; z-index: 10000; position: absolute;">\' . $template . \'</span>\';
}
