Hi,
I am trying to clean up my html form inputs before they hit mysql.
Is this possible as I've shown below? (It's not currently working?)
If it will work have I missed anything?
Thanks

$username=  sanitise($_POST['username']);

Open in new window


function sanitise($string) {
  $string = trim($string);
  $string = htmlentities($string);
  $string = strip_tags($string);
  $string = mysqli_real_escape_string($string);
  
  return $string;
}

PHP has built-in functions for this.  Look up filter_var() to learn more.  You will still need to use the escape_string functions.

function sanitise($string) {
  return mysqli_real_escape_string(trim(htmlentities(strip_tags($string))));
}

H'm I didn't know those functions existed.

I appreciate the code tweaks... never thought of doing it inline.

thanks
