Do I have to use mysql_real_escape_string if I bind parameters?

I have the following code:

function dbPublish($status)
{
 global $dbcon, $dbtable;

 if(isset($_GET['itemId']))
 {
  开发者_Python百科$sqlQuery = 'UPDATE ' . $dbtable . ' SET active = ? WHERE id = ?';
  $stmt = $dbcon->prepare($sqlQuery);
  $stmt->bind_param('ii', $status, $_GET['itemId']);
  $stmt->execute();
  $stmt->close();
 }
}

Do I need to mysql_real_escape_string in this case or am i okay?

No, you don't have to escape value yourself (i.e. no you don't need to call mysqli_real_escape_string), when you are using prepared statements : the DB engine will do that itself.

(Actually, if you were calling mysql_real_escape_string and using bound parameters, your strings would get escaped twice -- which would not be great : you'd end up with escaping characters everywhere...)

As a sidenote : your values are passed as integers (as indicated by the 'ii'), so you wouldn't have to call mysql_real_escape_string, even if you were not using prepared statements : as its name indicates, this function is used to escape... strings.

For integers, I generally just use intval to make sure the data I inject into my SQL queries really are integers.

(But, as you are using prepared queries, once again, you don't have to do that kind of escaping yourself)

No, you must not. Combining the two would result in visible escape characters showing up in your data.

function dbPublish($status)    
{    
 global $dbcon, $dbtable;    

 if(isset($_GET['itemId']))    
 {    
  $sqlQuery = 'UPDATE ' . $dbtable . ' SET active = ? WHERE id = ?';    
  $stmt = $dbcon->prepare($sqlQuery);    
  $stmt->bind_param('ii', $status, $_GET['itemId']);    
  $stmt->execute();    
  $stmt->close();    
 }    
}
