如何在此查詢語句中添加LIKE查詢而不是相等？

我得到這個錯誤，當我在我的查詢添加LIKE如何在此查詢語句中添加LIKE查詢而不是相等？

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' OR agent_ip = 'Counter' OR port = 'Counter' OR 0home_ip_por' at line 45

我的代碼是：

'.($search_field ?" AND home_id = '$search_field' OR user_id_main = '$search_field' OR home_path = '$search_field' 
          OR home_name = '$search_field' 
          OR user_id_main IN (SELECT `user_id` FROM `".$this->table_prefix."users` WHERE users_login = '$search_field') 
          OR user_id = '$search_field' 
          OR user_id IN (SELECT `user_id` FROM `".$this->table_prefix."users` WHERE users_login = '$search_field') 
          OR agent_ip = '$search_field' OR port = '$search_field' 
          " : '').

我需要在這條線來代替=到LIKEOR home_name = '$search_field'

可以嗎共享執行的查詢？ – farhadamjady

使用準備好的語句，否則即使您轉義變量，您也容易受到SQL注入的攻擊。 – Enstage

試試這個：

'.($search_field ?" AND home_id = '$search_field' OR user_id_main = '$search_field' OR home_path = '$search_field' OR home_name LIKE '%".$search_field."%' OR user_id_main IN (SELECT `user_id` FROM `".$this->table_prefix."users` WHERE users_login = '$search_field') OR user_id = '$search_field' OR user_id IN (SELECT `user_id` FROM `".$this->table_prefix."users` WHERE users_login = '$search_field') OR agent_ip = '$search_field' OR port = '$search_field'
