非大眾版WordPress純代碼實(shí)現(xiàn)閱讀量統(tǒng)計(jì)

wordpress 2023-11-06編輯：重慶網(wǎng)站建設(shè) WordPress 統(tǒng)計(jì) 代碼

因疫情影響，已經(jīng)2個(gè)多月沒有更新博客了，如果現(xiàn)在還不趕快出來冒個(gè)泡，怕大家誤認(rèn)為我走丟了（因?yàn)閺膩頉]有這么長(zhǎng)時(shí)間斷更過）。

目前我使用的Begin知更鳥主題，文章閱讀次數(shù)統(tǒng)計(jì)是依賴于PostViews插件，大家都知道WordPress的詬病就是插件越多越慢（其實(shí)在我看來并不是插件越多越慢，而是查詢、事件鉤子越多就越慢），所以自己就寫了一個(gè)純代碼版本，實(shí)現(xiàn)了閱讀統(tǒng)計(jì)和部分查詢函數(shù)。

當(dāng)然，可能你想說這些早就有人分享過了；是的，在我寫之前我肯定也會(huì)上網(wǎng)看看已存的，發(fā)現(xiàn)有幾點(diǎn)不如意，例如添加meta的鉤子是放在wp_head的、查詢閱讀數(shù)量必須要傳遞post_id等。

正文

我直接貼出代碼，每個(gè)函數(shù)的功能均在注釋中已經(jīng)標(biāo)識(shí)出：

<span class="hljs-comment">/**
 * 判斷閱讀數(shù)量是否需要增加并進(jìn)行操作
 */</span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">the_views_add</span><span class="hljs-params">($post_ID,$count,$key)</span></span>{
    <span class="hljs-keyword">if</span> (is_single() || is_page()) {
        <span class="hljs-keyword">if</span> ($count == <span class="hljs-string">''</span>) {
            add_post_meta($post_ID, $key, <span class="hljs-string">'0'</span>);
        } <span class="hljs-keyword">else</span> {
            update_post_meta($post_ID, $key, $count + <span class="hljs-number">1</span>);
            $count++;
        }
    }
    <span class="hljs-keyword">return</span> $count;
}
<span class="hljs-comment">//獲取當(dāng)前的閱讀數(shù)量與自增</span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">the_views</span> <span class="hljs-params">($post_id=null,$echo=true)</span> </span>{
    <span class="hljs-keyword">global</span> $post;
    <span class="hljs-keyword">if</span>($post_id==<span class="hljs-keyword">null</span>){
        $post_id = $post->ID;
    }
    $key = <span class="hljs-string">'views'</span>;
    $count = get_post_meta($post_id, $key, <span class="hljs-keyword">true</span>);
    <span class="hljs-keyword">if</span> ($count == <span class="hljs-string">''</span>) {
        $count = <span class="hljs-number">0</span>;
    }
    $count = the_views_add($post_id, $count, $key);
    $count = number_format_i18n($count);
    <span class="hljs-keyword">if</span>(!$echo){
        <span class="hljs-keyword">return</span> $count;
    }
    <span class="hljs-keyword">echo</span> $count;
}
<span class="hljs-comment">//設(shè)置文章發(fā)布的時(shí)候進(jìn)行字段添加</span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">set_views</span> <span class="hljs-params">($post_ID)</span> </span>{
    $key = <span class="hljs-string">'views'</span>;
    $count = get_post_meta($post_ID, $key, <span class="hljs-keyword">true</span>);
    <span class="hljs-keyword">if</span> ($count == <span class="hljs-string">''</span>) {
        add_post_meta($post_ID, $key, <span class="hljs-string">'0'</span>);
    }
}
add_action(<span class="hljs-string">'publish_post'</span>, <span class="hljs-string">'set_views'</span>);

這里再分享一個(gè)查詢函數(shù)，因?yàn)槭亲远x的所以就沒有插件的附帶函數(shù)支持，這個(gè)函數(shù)是查詢N天內(nèi)閱讀數(shù)量最多的文章：

<span class="hljs-comment">/**
 * 獲取查看最多的文章
 * <span class="hljs-doctag">@param</span> $days N天內(nèi)
 * <span class="hljs-doctag">@param</span> $nums 數(shù)量
 * <span class="hljs-doctag">@return</span> array|object|null
 */</span>
<span class="hljs-function"><span class="hljs-keyword">function</span> <span class="hljs-title">get_views_most_post</span><span class="hljs-params">($days, $nums)</span></span>{
    <span class="hljs-keyword">global</span> $wpdb;
    $sql = <span class="hljs-string">"select posts.*, meta.meta_value as views
            from {$wpdb->posts} as posts INNER JOIN (select post_id,(meta_value+0) as meta_value from 
            {$wpdb->postmeta} where meta_key='views' order by (meta_value+0) DESC) as meta
            on meta.post_id = posts.ID
            where posts.post_type = 'post'
            AND posts.post_status = 'publish' AND TO_DAYS(now()) - TO_DAYS(posts.post_date) < {$days}
            ORDER BY meta.meta_value DESC limit 0, {$nums}"</span>;
    <span class="hljs-keyword">return</span> $wpdb->get_results($sql);
}

后記

至于我為什么會(huì)分享這些代碼出來，因?yàn)樵谶^年期間博主寫了一套WordPress主題，目前整體框架和內(nèi)容都均已完成，現(xiàn)在處于優(yōu)化和測(cè)試期，后續(xù)上線會(huì)專門發(fā)文告知，有興趣的小伙伴歡迎多多關(guān)注，感謝你的支持！
