I don't why mysqli_real_escape_string will not add escape strings it seems like it should

$game = $_POST['game'];
$submit = $_POST['submit'];

if($submit){

require "scripts/db.ini.php";

$safe = mysqli_real_escape_string($db, $game);

$insert = "INSERT INTO `games`(`game`) VALUES ('$safe')";

mysqli_query($db,$insert);
}

im inserting I'm a "foobar" shouldnt it escape it with /

 

I don't think you understand what it does. It replaces a couple characters, namely ', with \' so you can insert them into the database.

 

Lets say you were inserting "Jim's Car" - if you didn't escape it, the query would fail, because the sql would read:

 

INSERT INTO `games`(`game`) VALUES ('Jim's Car')

 

So, when you escape it, it replaces Jim's Car with Jim\'s Car, you still get Jim's Car in the database, the backslashes are typically never seen.

 

 

So... yeah - thats escaping. It doesn't just randomly add slashes to strings, and you'll never see the slashes if you insert it into the database instead of print it to the screen.
