我的functions.php中有这段代码

global $current_user;
$userid = $current_user->ID;
$args = array(
    'post_type' => 'listings',
    'post_status' => 'publish',
    'author' => $userid
);
$the_posts = get_posts ( $args ); // get the published posts for that author
$post_count = count($the_posts); // count the number of published posts for the author
$N = 2; // set number for max posts per user
if ($post_count > $N) {
    if (current_user_is('s2member_level1')) {   


       // This is where I want to delete from wp_post where post_author = $userID


    }
}

我对 SQL 查询不够熟悉，无法弄清楚它为什么不起作用。我试过了

$wpdb = "DELETE FROM wp_posts WHERE post_author = $userID;"

和

$wpdb->query("DELETE FROM wp_posts WHERE post_author = $userID;");

全球 $wpdb; 在我的 php 文件中较早地定义

尝试使用 $user_ID = get_current_user_id(); 在全局 $current_user; 之后。或声明 $current_user 后的 get_currentuserinfo()；然后通过 $user_ID = $current_user->ID 获取当前用户 id。有关获取当前用户登录的更多信息，请参阅http://codex.wordpress.org/Function_Reference/get_currentuserinfo

查询应该是这样的：

DELETE FROM table WHERE ....;

在你的情况下：

"DELETE FROM wp_posts WHERE post_author = $userID;"

您应该用 ' 将值括起来

像这样：

$wpdb = "DELETE FROM wp_posts WHERE post_author = '$userID';"
