PHP：IF語句或mysql_query不起作用

Question

我強烈的感覺是IF或mysql_query不起作用。 （我想這是中頻）

if(isset($_POST['delete']) && $admin == "3"){ 
     $query = mysql_query("DELETE FROM dis_posts WHERE post_id = '".$posts['post_id']."'"); 
     $result = mysql_query($query); 
     header("Location: ". $_SERVER['REQUEST_URI']); 
    } 

請幫忙嗎？ 在此先感謝。

Answer 1

如果你的數據庫連接是正常的話
嘗試像這樣：

if(isset($_POST['delete']) && isset($admin) && $admin == "3"){ 
      $query = mysql_query("DELETE FROM dis_posts WHERE post_id = '".$posts['post_id']."'"); 
     if(!$query){ 

      echo "could not updated!"; 
     }else { 
      header("Location: ". $_SERVER['REQUEST_URI']); 
     } 
    } 

Answer 2

我可能是錯的，但是看起來也許這就是你正在嘗試做的...

if(isset($_POST['delete']) && $admin == "3"){ 
    $query = "DELETE FROM dis_posts WHERE post_id = '".$posts['post_id']."'"; 
    $result = mysql_query($query); 
    if($result){ 
     header("Location: ". $_SERVER['REQUEST_URI']); 
    } 
}
