将此添加到函数中。php

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 $count;
}
function setPostViews($postID) {
    $count_key = \'post_views_count\';
    $count = get_post_meta($postID, $count_key, true);
    if($count==\'\'){
        $count = 0;
        delete_post_meta($postID, $count_key);
        add_post_meta($postID, $count_key, \'0\');
    }else{
        $count++;
        update_post_meta($postID, $count_key, $count);
    }
}
