Description

描述

The template tag, wp_list_categories, displays a list of Categories as links. When a Category link is clicked, all the posts in that Category will display on a Category Page using the appropriate Category Template dictated by the Template Hierarchy rules. wp_list_categories works in much the same way as the two template tags replaced in WordPress 2.1, list_cats()(deprecated), and wp_list_cats()(deprecated).

模板标签wp_列表_类别,显示了关于[[WordPress:Glossary#Category|类别]的一个列表作为一个关于链接的列表。当点击一个类别的链接的时候,关于那个类别的所有文章都会显示在类别网页上,使用了模板层级规则规定的适当的类别标签wp_列表_类别 与WordPress2.1中被取代的两个标题的运行方式基本相同, 列表_cats()(取消的),和wp_列表_cats()(取消的)。

Include or Exclude Categories

包含或者删除类别

To sort categories alphabetically and include only the categories with IDs of 16, 3, 9 and 5, you could write the following code:

按字母顺序给类别分类,并且只包含ID是16,3,9,和5的类别,你可以写下以下的代码:

<ul>
<?php
wp_list_categories('orderby=name&include=3,5,9,16'); ?>
</ul>


<ul>
<?php
wp_list_categories('orderby=name&include=3,5,9,16'); ?>
</ul>


The following example displays category links sorted by name, shows the number of posts for each category, and excludes the category with the ID of 10 from the list.

下面的例子显示了根据名称分类的类别链接,显示了每个类别的文章数目,并且从列表中删除了ID是10的类别。

<ul>
<?php
wp_list_categories('orderby=name&show_count=1&exclude=10'); ?>
</ul>


<ul>
<?php
wp_列表_类别('orderby=name&show_count=1&exclude=10'); ?>
</ul>


Display or Hide the List Heading

显示或者隐藏列表标题

The title_li parameter sets or hides a title or heading for the category list generated by wp_list_categories. It defaults to '(__('Categories')', i.e. it displays the word "Categories" as the list's heading. If the parameter is set to a null or empty value, no heading is displayed. The following example code excludes categories with IDs 4 and 7 and hides the list heading:

title_liwp_list_categories产生的类别列表设置或者隐藏一个标题或者标头。默认'(__('Categories')',例如,显示单词"类别"作为列表的标题。如果参数设置为零,或者空参数,就不会显示标题。下面的例子代码排除了ID为4和7的类别并且隐藏了列表标题:

<ul>
<?php
wp_list_categories('exclude=4,7&title_li='); ?>
</ul>


<ul>
<?php
wp_list_categories('exclude=4,7&title_li='); ?>
</ul>


In the following example, only Cateogories with IDs 9, 5, and 23 are included in the list and the heading text has been changed to the word "Poetry", with a heading style of <h2>:

在下面的例子中,只有ID是9,5和23的类别包含在列表中,而且标题文本已经更改为"诗",标题样式为<h2>:

<ul>
<?php
wp_list_categories('include=5,9,23&title_li=<h2>' . __('Poetry') . '</h2>' ); ?>
</ul>


<ul>
<?php
wp_list_categories('include=5,9,23&title_li=<h2>' . __('Poetry') . '</h2>' ); ?>
</ul>


Only Show Children of a Category

只显示子类别

The following example code generates category links, sorted by ID, only for the children of the category with ID 8; it shows the number of posts per category and hides category descriptions from the title attribute of the generated links. Note: If there are no posts in a parent Category, the parent Category will not display.

下面的例子编码产生的类别链接,根据ID分类,只对于ID为8的子类别;显示每个类别的文章数目而且从产生的链接的标题 属性中隐藏了类别描述。注:如果母类别中没有包含文章,就不会显示母类别。

<ul>
<?php wp_list_categories('orderby=id&show_count=1
&use_desc_for_title=0&child_of=8'); ?>
</ul>


<ul>
<?php wp_list_categories('orderby=id&show_count=1
&use_desc_for_title=0&child_of=8'); ?>
</ul>

Display Categories with RSS Feed Links

显示拥有RSS Feed 链接的类别

The following example generates Category links sorted by name, shows the number of posts per Category, and displays links to the RSS feed for each Category.

下面的例子产生的类别链接,是根据名称分类的,显示了每个类别中的文章的数目,而且为每个类别显示了链接,连接到RSS feed。

<ul>
<?php
wp_list_categories('orderby=name&show_count=1&feed=RSS'); ?>
</ul>


<ul>
<?php
wp_list_categories('orderby=name&show_count=1&feed=RSS'); ?>
</ul>

To replace the rss link with a feed icon, you could write: 要用一个feed图标来代替rss链接,你可以编写:

<ul>
<?php
wp_list_categories('orderby=name&show_count=1
&feed_image=/images/rss.gif'); ?>
</ul>


<ul>
<?php
wp_list_categories('orderby=name&show_count=1
&feed_image=/images/rss.gif'); ?>
</ul>


Markup and Styling of Category Lists

类别列表的Markup和样式

By default, wp_list_categories() generates nested unordered lists (ul) within a single list item (li) titled "Categories".

默认情况下,wp_列表_类别()在一个单一的列表item(li)标题为"类别"的内部,产生嵌套的无序列表(ul)。


You can [[WordPress:#Display_or_Hide_the_List_Heading|remove the outermost item and list]] by setting the title_li [[WordPress:#Parameters|parameter]] to an empty string. You'll need to wrap the output in an ordered list (ol) or unordered list yourself (see the examples below). If you don't want list output at all, set the style parameter to none.

你可以通过将title_li [[WordPress:#Parameters|参数]]设置到一个空的字符串中,来[[WordPress:#Display_or_Hide_the_List_Heading|移除最外层的item 和列表]]。你需要自己结果覆盖在一个有序的列表(ol)或者无序的列表上(请看看下面的例子)。如果你不想要这些list output,将样式参数设置为没有

If the category list is generated on a Category Archive page, the list item for that category is marked with the HTML class current-cat. The other list items have no class.

如果类别列表是在类别归档网页上产生的,关于那个类别的list item被标记有HTML class current-cat。其它的list item没有class。

...
<li class="current-cat">
  [You are on this category page]
</li>
<li>
  [Another category]
</li>
...


...
<li class="current-cat">
  [You are on this category page]
</li>
<li>
  [Another category]
</li>
...

You can style that list item with a CSS selector :

你可以使用一个CSS 选择器来设计那个list item:

 .current-cat { ... }

.current-cat { ... }
