轉義後的正確語法？

Question

轉義後寫入正確的語法是什麼？

("SELECT torrent_download 
FROM " . DB_PREFIX . "auctions WHERE 
       auction_id='" . $item_details['auction_id'] .); 

我得到的錯誤是意外的「）」

我嘗試過各種「和」，但沒有一個似乎工作

Answer 1

您似乎缺少一個右'爲$item_details['auction_id']，最後才)，這將獲得雙引號括起來的"'");

("SELECT torrent_download 
    FROM " . DB_PREFIX . "auctions WHERE 
      auction_id='" . $item_details['auction_id'] . "'"); 

節省一點在雙引號字符串中有點麻煩，我建議使用{}機箱而不是拼接所有引號。但是，您不能包含常數DB_PREFIX。

("SELECT torrent_download 
    FROM " . DB_PREFIX . "auctions WHERE 
     auction_id='{$item_details['auction_id']}'"); 

Answer 2

("SELECT torrent_download 
FROM " . DB_PREFIX . "auctions WHERE 
      auction_id='" . $item_details['auction_id'] ."'"); 

Answer 3

("SELECT torrent_download 
FROM " . DB_PREFIX . "auctions WHERE 
      auction_id='" . $item_details['auction_id'] . "'"); 

你嘗試了嗎？這是「後面跟着」再次「。
