让WordPress分类/标签等存档页也能置顶文章-知新网

WordPress有原生的文章置顶功能，不过只支持在首页让置顶文章在顶部显示，其他如分类页、标签页、作者页和日期页等存档页面，就没法让置顶文章在顶部显示了，只能按默认的顺序显示。如何才能实现存档页面置顶文章呢？今天分享来自百度的方法。

将下面的代码添加到主题的 functions.php 文件即可：

代码说明

1、如果你想让存档页也都显示全部置顶文章，那么就删掉12-45行的代码；
2、如果不想在某分类页显示置顶文章，将第 3 行的

<span class="token keyword">if</span><span class="token punctuation">(</span>

改成：

<span class="token comment">// abc是分类名称</span><span class="token keyword">if</span> <span class="token punctuation">(</span> <span class="token function">is_category</span><span class="token punctuation">(</span> <span class="token string single-quoted-string">'abc'</span> <span class="token punctuation">)</span> <span class="token operator">||</span>

3、如果不想某标签页显示置顶文章，将第 3 行的

<span class="token keyword">if</span><span class="token punctuation">(</span>

改成：

<span class="token comment">// abc是标签名称</span><span class="token keyword">if</span> <span class="token punctuation">(</span> <span class="token function">is_tag</span><span class="token punctuation">(</span> <span class="token string single-quoted-string">'abc'</span> <span class="token punctuation">)</span> <span class="token operator">||</span>

4、如果不想某作者页显示置顶文章，将第 3 行的

<span class="token keyword">if</span><span class="token punctuation">(</span>

改成：

<span class="token comment">// abc是作者昵称</span><span class="token keyword">if</span> <span class="token punctuation">(</span> <span class="token function">is_author</span><span class="token punctuation">(</span> <span class="token string single-quoted-string">'abc'</span> <span class="token punctuation">)</span> <span class="token operator">||</span>

5、以上代码只对主循环有效，如果你在存档页使用WP_Query或query_posts来获取文章列表，又想让这些列表顶部显示置顶文章，可以把第3行代码中的以下代码删掉(注意：可能会导致文章显示数量跟你设置的不一样)：

<span class="token operator">||</span> <span class="token operator">!</span><span class="token function">is_main_query</span><span class="token punctuation">(</span><span class="token punctuation">)</span>

置顶样式

如果你想给置顶文章添加样式，将以下代码添加到functions.php中，会给置顶文章添加一个名为 sticky 的class。具体的css代码，再自行自定义：

<span class="token function">add_filter</span><span class="token punctuation">(</span><span class="token string single-quoted-string">'post_class'</span><span class="token punctuation">,</span>  <span class="token string single-quoted-string">'addStickyClass'</span> <span class="token punctuation">,</span><span class="token number">10</span><span class="token punctuation">,</span><span class="token number">3</span> <span class="token punctuation">)</span><span class="token punctuation">;</span><span class="token keyword">function</span> <span class="token function-definition function">addStickyClass</span><span class="token punctuation">(</span> <span class="token variable">$classes</span><span class="token punctuation">,</span> <span class="token variable">$class</span><span class="token punctuation">,</span> <span class="token variable">$post_id</span> <span class="token punctuation">)</span><span class="token punctuation">{</span>  <span class="token keyword">if</span><span class="token punctuation">(</span> <span class="token function">is_sticky</span><span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token operator">&&</span> <span class="token function">is_category</span><span class="token punctuation">(</span><span class="token punctuation">)</span> <span class="token operator">&&</span> <span class="token operator">!</span><span class="token keyword">isset</span><span class="token punctuation">(</span> <span class="token variable">$classes</span><span class="token punctuation">[</span><span class="token string single-quoted-string">'sticky'</span><span class="token punctuation">]</span> <span class="token punctuation">)</span> <span class="token punctuation">)</span><span class="token punctuation">{</span>    <span class="token variable">$classes</span><span class="token punctuation">[</span><span class="token punctuation">]</span> <span class="token operator">=</span> <span class="token string single-quoted-string">'sticky'</span><span class="token punctuation">;</span>  <span class="token punctuation">}</span>    <span class="token keyword">return</span> <span class="token variable">$classes</span><span class="token punctuation">;</span><span class="token punctuation">}</span>
