mysql - PHP Like Function with combination code -

<form method="post" action="post.php"> <input type="text" name="code"/> </form> 

---

<?php $code = $_post['code']; include ("db.php"); $query = mysql_query("select * t_code code '$code'"); if(mysql_num_rows($query)) { echo "got data"; } else echo "no data"; } 

in table t_code

code_id | code 1       | gg125-0015 2       | ba512-1152
