为什么后视图计数功能不工作?

wordpress php

Harley Liang · 技术社区 · 6 年前

很好的一天。我一直在研究如何根据 this 链接

但是,当我调用存储在循环中的single.php中的函数时,不管我刷新浏览器多少次,我刚发布的帖子仍然保持0视图(帖子没有更新帖子视图计数)。如果有任何帮助,我将不胜感激。

my functions.php文件-用于后视图计数的代码

function subh_set_post_view($postID)
{
    $count_key = 'post_views_count';
    $count = (int) get_post_meta($postID, $count_key, true);
    if ($count == '') {
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return $count . 'View ';
    } else {
        $count++;
        update_post_meta($postID, $count_key, (string) $count);
    }
}

function getPostViews($postID){
    $count_key = 'post_views_count';
    $count = get_post_meta($postID, $count_key, true);
    if($count==''){
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, '0');
        return "0 View";
    }
    return $count.' Views';
}

/**
 * Add a new column in the admin panel posts list
 *
 * @param $defaults
 *
 * @return mixed
 */
function subh_posts_column_views($defaults)
{
    $defaults['post_views'] = __('Views');

    return $defaults;
}

/**
 * Display the number of views for each posts on the admin panel
 *
 * @param $column_name
 * @param $id
 *
 * @return void simply echo out the number of views
 */
function subh_posts_custom_column_views($column_name, $id)
{
    if ($column_name === 'post_views') {
        echo subh_get_post_view(get_the_ID());
    }
}

add_filter('manage_posts_columns', 'subh_posts_column_views');
add_action('manage_posts_custom_column', 'subh_posts_custom_column_views', 5, 2);

我的single.php文件:

尝试此代码。

function subh_set_post_view($postid)
{

$count ou key='post ou views ou count';
$count=(int)获取\u post\u元($postid,$count\u键,真);

如果($count==0){
计数+ +;
删除\u post_meta($postid,$count_key);
添加_post_meta($postid,$count_key,$count++);
}否则{
计数+ +;
更新_post_meta($postid,$count_key,$count);
}

}

函数getPostView($postId){
$count ou key='post ou views ou count';
$count=get_post_meta($postid,$count_key,true);
返回$count。“视图”;
}

/**
*在“管理面板文章”列表中添加新列
*
*@参数$默认值
*
*@返回混合
*/
函数subh_posts_column_views($defaults)
{
$defaults['post_views']=uu('views');

返回$defaults;
}

/**
*显示管理面板上每个日志的视图数
*
*@参数$列名称
*@ PARAM$ID
*
*@返回void只返回视图数
*/
函数subh_posts_custom_column_views($column_name,$id)
{
如果($column_name=='发布视图'){
echo getPostView(get_the_id());
}
}

添加_filter('manage_posts_columns'、'subh_posts_column_views');
添加\action('manage_posts_custom_column'、'subh_posts_custom_column_views',5,2);
< /代码>

get_the_ID() :检索WordPress中当前项目的ID 循环。

这就是你的功能失效的原因。你可以使用 GETHythiId() 只有在循环内部,不能在single.php上使用它。
