Question

I try to Insert Into to table some values but i have a problem. there are unnecessary characters (\n) in the fields key1,key2,key3,key4. Here’s an example:

INSERT INTO questions (`key1`,`key2`, `key3`, `key4`, `user_id`, `creation_date`, `taksi`, `type`, `permission`)
        VALUES ('\n17','\n18','\n19','\n20','5','2012-12-18 14:37:31', '1', 'multiple_choice', '0') 

how can I avoid \n ?

original code:

$user_id = $_SESSION['id'];

      $key1 = mysql_real_escape_string($_GET['key1']);
      $key2 = mysql_real_escape_string($_GET['key2']);
      $key3 = mysql_real_escape_string($_GET['key3']);
      $key4 = mysql_real_escape_string($_GET['key4']);

      $taksi = mysql_real_escape_string($_GET['taksi']);
      $permission = mysql_real_escape_string($_GET['permission']);

$sql = "INSERT INTO questions (`key1`,`key2`, `key3`, `key4`, `user_id`, `creation_date`, `taksi`, `type`, `permission`)
        VALUES ('".$key1."','".$key2."','".$key3."','".$key4."','".$user_id."','".$today."', '".$taksi."', '".$type."', '".$permission."')";
        mysql_query($sql);

Answer 1

PHP str_replace. Create your query as a String variable, and then replace all instances of \n with nothingness.
