如何在foreach WordPress模板中獲取tag_description？

Question

我做了這個劇本，

<?php 
function top_tags() { 
    $tags = get_tags(); 

    if (empty($tags)) 
     return; 

    $counts = $tag_links = array(); 
    foreach ((array) $tags as $tag) { 
     $counts[$tag->name] = $tag->count; 
     $tag_links[$tag->name] = get_tag_link($tag->term_id); 
    } 

    asort($counts); 
    $counts = array_reverse($counts, true); 

    $i = 0; 
    foreach ($counts as $tag => $count) { 
     $i++; 
     $tag_link = clean_url($tag_links[$tag]); 
     $tag = str_replace(' ', '&nbsp;', wp_specialchars($tag)); 
     if($i < 11){ 
      print "<li><a href=\"$tag_link\">$tag ($count) </a></li>"; 
     } 
    } 
} 
?> 

但我似乎無法得到每個標籤的tag_description。如果我在foreach函數中使用$description = tag_description();，它不會顯示任何內容。

......怎麼這樣：

<?php 
function top_tags() { 
    $tags = get_tags(); 

    if (empty($tags)) 
     return; 

    $counts = $tag_links = array(); 
    foreach ((array) $tags as $tag) { 
     $counts[$tag->name] = $tag->count; 
     $tag_links[$tag->name] = get_tag_link($tag->term_id); 
    } 

    asort($counts); 
    $counts = array_reverse($counts, true); 

    $i = 0; 
    foreach ($counts as $tag => $count) { 
     $i++; 
     $tag_link = clean_url($tag_links[$tag]); 
     $tag_description = tag_description(get_term_by('name', $tag, 'post_tag')->term_id); 
     $tag = str_replace(' ', '&nbsp;', wp_specialchars($tag)); 
     if($i < 11){ 
      print "<li><a href=\"$tag_link\">$tag ($count) </a> $tag_description </li>"; 
     } 
    } 
} 
?> 

一個這樣做（未經測試）的更有效的方法：

<?php 
function top_tags() { 
    $tags = get_tags(); 

    if (empty($tags)) 
     return; 

    $counts = $tag_links = array(); 
    foreach ((array) $tags as $tag) { 
     $counts[$tag->name] = $tag->count; 
     $tag_links[$tag->name] = array('url' => get_tag_link($tag->term_id), 'description' => $tag->description); 
    } 

    asort($counts); 
    $counts = array_reverse($counts, true); 

    $i = 0; 
    foreach ($counts as $tag => $count) { 
     $i++; 
     $tag_link = clean_url($tag_links[$tag]['url']); 
     $tag_description = $tag_links[$tag]['description']; 
     $tag = str_replace(' ', '&nbsp;', wp_specialchars($tag)); 
     if($i < 11){ 
      print "<li><a href=\"$tag_link\">$tag ($count) </a> $tag_description </li>"; 
     } 
    } 
} 
?>

只是對你的想法發表意見，這不應該使用，你可以使用tag_description您foreach循環內如下

$description = tag_description($tag->term_id); 

以上方法我不是錯，但get_tags已經返回標籤說明您可以返回如下

$tag->description 

編輯

看到的是由get_tags返回，請執行下列操作

$tags = get_tags; 
?><pre><?php var_dump($tags); ?></pre><?php
