從wp_posts刪除WHERE post_author = $ userID;

Question

我有這樣的代碼在我的functions.php

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 


    } 
} 

我不是SQL查詢足夠熟悉弄清楚爲什麼它不工作。我試過

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

和

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

全球WPDB $;是在我的php文件中更早定義的

Answer 1

刪除應該寫入不帶*字符。

Answer 2

查詢應該是這樣的：

DELETE FROM table WHERE ....; 

你的情況

：

"DELETE FROM wp_posts WHERE post_author = $userID;" 

Answer 3

你應該附上與'價值

像這樣：

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

Answer 4

嘗試使用$ user_ID = get_curre nt_user_id（）;全球$ current_user;之後。或聲明$ current_user後的get_currentuserinfo（）;然後通過$ user_ID = $ current_user-> ID獲取當前用戶標識。有關獲取當前用戶登錄的詳細信息，請參閱http://codex.wordpress.org/Function_Reference/get_currentuserinfo
