Comment (by euromark):
i am very glad this will finally be an issue of high priority in 1.3
:)[[BR]]
in summer 2008, i already pointed out how severe this issue might effect
any website built with cake.
[[BR]]
[[BR]]
since this time i had to continuously hack into the core validation.php in
order to ensure correct validation (replaced str() functions with mb_str()
functions)
[[BR]]
[[BR]]
some people in America will now think, who cares, my site is only visited
by American fellows.[[BR]]
well, the visitors still could inject multibyte characters such as äöü
into forms which usually results in incorrect validation[[BR]]
what i want to say is, that the multibyte functions should not only be
fully supported, but also be 100% integrated into the core.
[[BR]]
[[BR]]
here is what is neccessary to ensure proper "woldwide" validation (if utf8
is your encoding):
[[BR]]
[[BR]]
a)
[[BR]]
mb_internal_encoding('UTF-8'); # important!
[[BR]]
(could be invoked by setting Configure::App.encoding to UTF-8)
[[BR]]
[[BR]]
b)
[[BR]]
in /libs/validation.php (one example on the between validation):
{{{
function between($check, $min, $max) {
//$length = strlen($check);
$length = mb_strlen($check); # CORE-HACK 2008-09-12 ms
| now the character are counted correctly
return ($length >= $min && $length <= $max);
}
}}}
the same goes for minLength, maxLength, etc (or _luhn() for the cc
validation)
