WordPress - 自定义分类问题的相关帖子
我正在尝试根据自定义分类法显示相关帖子。我在 wordpress.org 上发现了一个类似的查询。然而,原始帖子在结果中多次重复。 (单词是我使用的自定义分类法的名称)似乎发生的情况是,根据设置的显示数量,单个帖子会被重复。知道什么可能导致这种情况吗?
代码:
<?php
//for in the loop, display all "content", regardless of post_type,
//that have the same custom taxonomy (e.g. words) terms as the current post
$backup = $post; // backup the current object
$found_none = '<h2>No related posts found!</h2>';
$taxonomy = 'words';// e.g. post_tag, category, custom taxonomy
$param_type = 'words'; // e.g. tag__in, category__in, but genre__in will NOT work
$post_types = get_post_types( array('public' => true), 'names' );
$tax_args=array('orderby' => 'none');
$tags = wp_get_post_terms( $post->ID , $taxonomy, $tax_args);
if ($tags) {
foreach ($tags as $tag) {
$args=array(
"$param_type" => $tag->slug,
'post__not_in' => array($post->ID),
'post_type' => $post_types,
'showposts'=>5,
'caller_get_posts'=>1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3>
<?php $found_none = '';
endwhile;
}
}
}
if ($found_none) {
echo $found_none;
}
$post = $backup; // copy it back
wp_reset_query(); // to use the original query again
?>
I'm trying to display related posts based on a custum taxonomy. I found a query at wordpress.org that kind of works. However the original post gets duplicated in the results multiple times. (words is the name of the custom taxonomy I use) What seems to happen is that the single post gets duplicated according to what amount showpost is set. Any idea's what could cause this?
The code:
<?php
//for in the loop, display all "content", regardless of post_type,
//that have the same custom taxonomy (e.g. words) terms as the current post
$backup = $post; // backup the current object
$found_none = '<h2>No related posts found!</h2>';
$taxonomy = 'words';// e.g. post_tag, category, custom taxonomy
$param_type = 'words'; // e.g. tag__in, category__in, but genre__in will NOT work
$post_types = get_post_types( array('public' => true), 'names' );
$tax_args=array('orderby' => 'none');
$tags = wp_get_post_terms( $post->ID , $taxonomy, $tax_args);
if ($tags) {
foreach ($tags as $tag) {
$args=array(
"$param_type" => $tag->slug,
'post__not_in' => array($post->ID),
'post_type' => $post_types,
'showposts'=>5,
'caller_get_posts'=>1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title(); ?>"><?php the_title(); ?></a></h3>
<?php $found_none = '';
endwhile;
}
}
}
if ($found_none) {
echo $found_none;
}
$post = $backup; // copy it back
wp_reset_query(); // to use the original query again
?>

您在
foreach
循环内得到了重复项。该代码实际上是在说;$param_type
因此,如果您有一篇标记有多个术语的帖子属于同一分类,很可能会出现不止一次。
您可以迭代地将查询的帖子添加到
post__not_in
数组中,以确保它们不会再次出现;在
if ($tags) {
上方添加
$post_not_in = array($post->ID);
然后替换行
post__not_in' =>; array($post->ID),
withpost__not_in' =>; $post_not_in,
.最后,将
$post_not_in[] = get_the_ID();
放入while
循环中,位于$found_none = '';
It's inside the
foreach
loop that you're getting duplications. That code is effectively saying;$param_type
So if you have a post that is tagged with more than one term of the same taxonomy, it's likely it will appear more than once.
You can iteratively add queried posts into the
post__not_in
array to ensure they don't appear again;Add
$post_not_in = array($post->ID);
just aboveif ($tags) {
Then replace the line
post__not_in' => array($post->ID),
withpost__not_in' => $post_not_in,
.Finally, drop
$post_not_in[] = get_the_ID();
inside yourwhile
loop, after$found_none = '';
对于我来说,我使用 这个插件自定义分类法相关帖子。我希望该插件能够帮助您解决问题。
As for me i use this plugin for custom taxonomy relate post. I hope that plugin will help your problem.
