secure function - mysql_real_escape_string

[Dat]

Hey I have this form and I run it through a secure function:

 

function isSecure($string)
{
$string = strip_tags($string);
$string = htmlspecialchars($string);
$string = trim($string);
$string = stripslashes($string);
$string = mysql_real_escape_string($string);
return $string;
}

 

But I can't figure out why this happens when I submit something like this into my profile edit form:

 

now it works here @#$%^&*()

Why does this\' happen but this doesn\'t:
"HERE"

 

As you can see it add's slashes to the ' but not to the ". I want to remove those \.

Well your calling mysql_real_escape_string which will add slashes to and apostrophes. Removing the mysql_real_escape_string should do the trick.
