    To insert value from array with named key to string, and to use '' marks, you must enclose it in {} – http://www.php.net/manual/en/language.types.string.php#language.types.string.parsing (Complex (curly) syntax)
    So, for example,

    $adduser= "INSERT INTO users set 
user_name=$_POST['user_name'],
user_password=$_POST['user_password'],
user_mail =$_POST['user_mail']";

    must be 

    $adduser= "INSERT INTO users set 
user_name=\"{$_POST['user_name']}\",
user_password=\"{$_POST['user_password']}\",
user_mail =\"{$_POST['user_mail']}\"";
