如何按日期限制wordpress tagcloud？

发布于 2024-09-04 06:32:22 字数 373 浏览 2 评论 0 原文

我已经搜索了很长一段时间，以找到一种方法来按日期限制 WordPress 标签，并按它们在选定时间范围内出现的次数对它们进行排序。但我一直比较不成功。

我想要实现的目标类似于 Twitter 上的热门话题。但在这种情况下，“趋势标签”。默认情况下，wordpress tagcloud 显示有史以来最流行的标签。这对我来说没有意义，因为我想跟踪当前的趋势。

理想情况下，它会是这样的：

今天最受欢迎的标签

奥巴马（18 次提及）
纽约（15 次提及）
钢铁侠（11 次提及）
罗宾汉（7 次提及）

然后乘以“本周最受欢迎”和“本周最受欢迎”月'。有谁知道如何实现这一目标？

好的，所以我想您可能想要的是对最后 50 个帖子执行此操作。

循环遍历最后 n 个帖子，提取每个帖子的每个标签的 term_id，然后将该字符串传递到 include 参数中="http://codex.wordpress.org/Template_Tags/wp_tag_cloud" rel="nofollow noreferrer">wp_tag_cloud();

$how_many_posts = 50;
$args = array(
    'posts_per_page' => $how_many_posts,
    'orderby' => 'date',
    'order' => 'DESC',
);
// get the last $how_many_posts, which we will loop over
// and gather the tags of
query_posts($args);
//
$temp_ids = array();
while (have_posts()) : the_post(); 
    // get tags for each post
    $posttags = get_the_tags();
    if ($posttags) {
        foreach($posttags as $tag) {
            // store each tag id value
            $temp_ids[] = $tag->term_id;
        }
    }
endwhile;
// we're done with that loop, so we need to reset the query now
wp_reset_query();
$id_string = implode(',', array_unique($temp_ids));
// These are the params I use, you'll want to adjust the args
// to suit the look you want    
$args = array(
    'smallest'  => 10, 
    'largest'   => 30,
    'unit'      => 'px', 
    'number'    => 150,  
    'format'    => 'flat',
    'separator' => "\n",
    'orderby'   => 'count', 
    'order'     => 'DESC',
    'include'   => $id_string,  // only include stored ids
    'link'      => 'view', 
    'echo'      => true,

);
wp_tag_cloud( $args );

Okay, so what I think you probably want is to do this for say, the last 50 posts.

Loop over the last n posts, extract the term_id of each tag for each post, then pass that string into the include argument of wp_tag_cloud();

$how_many_posts = 50;
$args = array(
    'posts_per_page' => $how_many_posts,
    'orderby' => 'date',
    'order' => 'DESC',
);
// get the last $how_many_posts, which we will loop over
// and gather the tags of
query_posts($args);
//
$temp_ids = array();
while (have_posts()) : the_post(); 
    // get tags for each post
    $posttags = get_the_tags();
    if ($posttags) {
        foreach($posttags as $tag) {
            // store each tag id value
            $temp_ids[] = $tag->term_id;
        }
    }
endwhile;
// we're done with that loop, so we need to reset the query now
wp_reset_query();
$id_string = implode(',', array_unique($temp_ids));
// These are the params I use, you'll want to adjust the args
// to suit the look you want    
$args = array(
    'smallest'  => 10, 
    'largest'   => 30,
    'unit'      => 'px', 
    'number'    => 150,  
    'format'    => 'flat',
    'separator' => "\n",
    'orderby'   => 'count', 
    'order'     => 'DESC',
    'include'   => $id_string,  // only include stored ids
    'link'      => 'view', 
    'echo'      => true,

);
wp_tag_cloud( $args );

我很确定标签没有时间戳 - 也许您可以搜索特定时间段内具有特定标签的帖子？

我认为你可以查看一些插件，看看是否有你需要的插件

您可以通过查询获取标签列表，这样您就不必循环抛出最后一个帖子。

<ul id="footer-tags">
<?php $wpdb->show_errors(); ?> 
<?php
global $wpdb;
$term_ids = $wpdb->get_col("
    SELECT term_id FROM $wpdb->term_taxonomy
    INNER JOIN $wpdb->term_relationships ON $wpdb->term_taxonomy.term_taxonomy_id=$wpdb->term_relationships.term_taxonomy_id
    INNER JOIN $wpdb->posts ON $wpdb->posts.ID = $wpdb->term_relationships.object_id
    WHERE DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= $wpdb->posts.post_date");

if(count($term_ids) > 0){

  $tags = get_tags(array(
    'orderby' => 'count',
    'order'   => 'DESC',
    'number'  => 28,
    'include' => $term_ids,
  ));
foreach ( (array) $tags as $tag ) {
echo '<li><a href="' . get_tag_link ($tag->term_id) . '" rel="tag">' . $tag->name . '</a></li>';
}
}
?>
</ul>

Yo can get the tag list with a query so you don't have to make a loop throw the last X post.

<ul id="footer-tags">
<?php $wpdb->show_errors(); ?> 
<?php
global $wpdb;
$term_ids = $wpdb->get_col("
    SELECT term_id FROM $wpdb->term_taxonomy
    INNER JOIN $wpdb->term_relationships ON $wpdb->term_taxonomy.term_taxonomy_id=$wpdb->term_relationships.term_taxonomy_id
    INNER JOIN $wpdb->posts ON $wpdb->posts.ID = $wpdb->term_relationships.object_id
    WHERE DATE_SUB(CURDATE(), INTERVAL 30 DAY) <= $wpdb->posts.post_date");

if(count($term_ids) > 0){

  $tags = get_tags(array(
    'orderby' => 'count',
    'order'   => 'DESC',
    'number'  => 28,
    'include' => $term_ids,
  ));
foreach ( (array) $tags as $tag ) {
echo '<li><a href="' . get_tag_link ($tag->term_id) . '" rel="tag">' . $tag->name . '</a></li>';
}
}
?>
</ul>
